The timepiece armor assemblymain portion 2 has a frame-like case band 4, acover glass 5 mounted to a surface of thecase band 4, and a case back 6 mounted to a back face of thecase band 4. Thefront lid 3 is attached to thecase band 4 through apivot axle 7 so as to be opened or closed thecover glass 5. - Detailedly, as shown in FIG. 7B, the
front lid 3 is provided with two short, cylindrical axle fittingportions 8 protruding from its circumference edge, and thecase band 4 is provided with a short, cylindrical pivot axle supporting convex portion 9. The pivot axle supporting convex portion 9 is disposed between the two axlefitting portions 8, and both end portions of thepivot axle 7 penetrating through this pivot axle supporting convex portion 9 are respectively inserted into the axle fittingportions 8. Therefore, thefront lid 3 can rotate about an axis of thepivot axle 7 over an opened position not covering acover glass 5 and a closed position covering thecover glass 5. - Torsion springs10 wound around the
pivot axle 7 are respectively interposed between the pivot axle supporting convex portion 9 and the axle fittingportions 8. Thetorsion spring 10 is provided from its free state to wound state and, as shown in FIG. 7A, oneend portion 10 a butts against the circumference edge of thefront lid 3 and theother end portion 10 b butts against the surface of thecase band 4 and is supported thereby. By this constitution, since a spring force of thetorsion spring 10 is given to thefront lid 3 through oneend portion 10 a, thefront lid 3 is always biased in its closing direction. Therefore, thefront lid 3 can be maintained so as not to be opened carelessly. As to this pocket watch, a user can see a dial and the like by pressing and opening thefront lid 3 by means of his/her finger against the spring force of thetorsion spring 10. - Further, in a conventional portable apparatus with lid, two hinge portions protruding from a case are provided, and two-step through-hole is formed in this hinge portion. After a pin has been loosely fitted to the two-step through-hole of the hinge portion, of one side, protrusively provided in a case main body, and an elastic body, such as urethane resin, previously maintained in a through-hole provided in a connecting base of the lid has been inserted through the pin, a split pipe is fitted to a tip of the pin under a state that the tip of the pin faces an inside of a large diameter portion of the two-step through-hole of the hinge portion of the other side. In this manner, the lid is connected to the case main body (refer to, for example,
Patent Document 1, JP-A-7-248387 Gazette, pages 2-3, FIGS. 1-3) - Hitherto, since the
torsion spring 10 disposed between theaxle fitting portion 8 and the pivot axle supporting convex portion 9 is exposed, by the fact that it is seen, it is liable to give an unsightliness in external appearance. - As to the constitution in which the
front lid 3 is biased in its closing direction, the bothend portions torsion spring 10 used therefor are exposed to an outside of thefront lid 3. In this case, there is the fact that, as shown in FIG. 7(A), oneend portion 10 a is slightly exposed from a surface of thefront lid 3 by a dispersion in length of the bothend portions front lid 3, and the like. Under such a situation, there is a fear that oneend portion 10 a and the like are caught by user's finger, clothes and the like when handling and the like. - As mentioned already, as to the constitution in which the
front lid 3 is biased in its closing direction, there is no device for limiting an opening of thefront lid 3 at a predetermined open position. Therefore, if thefront lid 3 is excessively opened, the spring force of thetorsion spring 10 becomes weak by an excessive load accompanying thereby, so that there is a fear that a function of always maintaining thefront lid 3 to its closed state is decreased. - Accordingly, a problem to be solved by the present invention is to provide a portable apparatus with opening/closing lid and a timepiece armor assembly for watch, each of which can improve the external appearance, in each of which clothes and the like are not caught by the end portion of the spring biasing the opening/closing lid, and each of which can maintain the biasing function for the opening/closing lid by the spring.
- A premise of the present invention is a portable apparatus with opening/closing lid, in which to a frame-like portion of an apparatus armor main portion there is rotatably attached, through a pivot axle, the opening/closing lid for opening or closing individually a front face or a back face or both of these faces of the main portion, and this opening/closing lid is biased in its closing direction or opening direction by a spring.
- And, the present invention for solving the above problem is characterized in that the opening/closing lid is provided with a cylindrical axle fitting portion rotatably fitting to the pivot axle, a spring accommodating hole facing this axle fitting portion is provided in a position biased from an axle center of the pivot axle of the frame-like portion, the spring consisting of a coil spring is accommodated in this spring accommodating hole under its compressed state, and the opening/closing lid is biased by giving a spring force of this spring to the axle fitting portion.
- In the present invention and each invention mentioned below, the frame-like portion of the apparatus armor main portion and the opening/closing lid can be made of a metal or a synthetic resin and, in case of the synthetic resin, they can be made of one having a transparency capable of seeing therethrough an inside not limited opaque one. In the present invention and each invention mentioned below, the spring accommodating hole extends in a thickness direction of the frame-like portion and can be provided approximately perpendicularly to an axis of the pivot axle (there is included a case where the axis is perpendicular or slanted at an angle less than 10° approximating to a perpendicularity). In case where the spring accommodating hole is provided perpendicularly, it is excellent in a point that it is unnecessary to increase an outer diameter of the frame-like portion by increasing a wall thickness along a radial direction of the frame-like portion. In case where the spring accommodating hole is slantingly provided, it is excellent in a point that such a design becomes possible that a lever action given to the opening/closing lid is easily developed by largely ensuring a distance between a line of force of the spring and the axle center (fulcrum) of the pivot axle. In the present invention, a biasing force of the coil spring can be directly given to the axle fitting portion by causing one end portion of this spring to contact with the axle fitting portion or, by interposing a transmission body between one end portion of the coil spring and the axle fitting portion, the biasing force of the coil spring can be indirectly given to the axle fitting portion through this transmission body.
- In the present invention, since the biasing force of the spring is applied to the axle fitting portion possessed by the opening/closing lid in a position biased from the axle center of the pivot axle, the opening/closing lid can be biased in a predetermined direction by the lever action whose fulcrum is made the pivot axle. The spring bearing this biasing force is the coil spring, and is accommodated in the spring accommodating hole of the frame-like portion possessed by the apparatus armor main portion. Since this spring accommodating hole faces the axle fitting portion, the whole coil spring is substantially covered and concealed by the frame-like portion and the axle fitting portion such that the coil spring is not exposed to an outside of the apparatus armor main portion and, by covering an end portion of the coil spring in the vicinity of the axle fitting portion by means of the axle fitting portion, this end portion can be made so as not to protrude to the outside of the apparatus armor main portion. And, in case where the opening/closing lid biased in its closing direction is excessively opened for instance, a load applied accompanying this to the coil spring is proportional to a distance from the axle center of the pivot axle to an outer circumference face of the axle fitting portion, but there is no fact that an excessive force greater than a certain constant quantity is applied to the coil spring because the axle fitting portion is cylindrical.
- In a preferred mode of the present invention, the transmission body having a convex curved face contacting with the axle fitting portion is interposed between the spring and the axle fitting portion. In this mode, the transmission body may be a pin-like one only whose tip portion is semispheric or has an approximately inverted U-shape in section, or it may be a solid sphere which is spherical as a whole, and this transmission body can be made of a metal or a synthetic resin.
- In this mode, by using the transmission body, it become easy to accurately determine the point of force by the coil spring with respect to the axle fitting portion, and the coil spring in the spring accommodating hole can be covered and concealed from the axle fitting portion side by this transmission body.
- In a preferred mode of the present invention, an outer circumference region, of the axle fitting portion, facing the spring accommodating hole accompanying the fact that the opening/closing lid biased in its closing direction is opened from its closed state is formed in an arc face. In this mode, it is desirable that the outer circumference region of the axle fitting portion is formed by the arc face whose radius from the axle center of the pivot axle is an equal distance, but it may be formed by an arc face the radius of which slightly, gradually increases or gradually decreases.
- In this mode, in case where it is attempted to excessively open the opening/closing lid, since the outer circumference region formed by the arc face of the axle fitting portion faces the spring accommodating hole, the opening/closing lid can be further opened while suppressing an excessive force from being applied to the coil spring. Consequently, it can be adapted such that no excessive load is given to an attaching portion of the opening/closing lid.
- In a preferred mode of the present invention, plural flat pressure-receiving outer circumference regions continuous in a circumferential direction are provided in the outer circumference face of the axle fitting portion.
- In this mode, on the occasion of an opening/closing motion of the opening/closing lid, every time a corner portion formed between the adjoining pressure-receiving outer circumference regions passes over the point of force of the coil spring, a momentary compression and release of the coil spring is performed, so that it is possible to give a click feeling.
- The portable apparatus with opening/closing lid of the present invention can be implemented for a pocket watch or wristwatch, which is a watch. Accordingly, the watch of the present invention has such advantages that an external appearance is improved, clothes and the like are not caught by an end portion of the spring biasing the opening/closing lid, and a biasing function for the opening/closing lid by the spring can be maintained.
- Further, a premise of the present invention is an armor assembly for watch, in which to a case band of a timepiece armor main portion there is rotatably attached, through the pivot axle, a front lid for opening or closing a surface of the main portion, and this front lid is biased in its closing direction by the spring.
- And, the present invention for solving the above problem is characterized in that the front lid is provided with the cylindrical axle fitting portion rotatably fitting to the pivot axle, the spring accommodating hole facing this axle fitting portion is provided in the position biased from the axle center of the pivot axle of the frame-like portion, the spring consisting of the coil spring is accommodated in this spring accommodating hole under its compressed state, and the front lid is biased by giving the spring force of this spring to the axle fitting portion.
- In this invention, since the biasing force of the spring is applied to the axle fitting portion possessed the front lid in the position biased from the axle center of the pivot axle, the front lid can be biased in the predetermined direction by the lever action whose fulcrum is made the pivot axle. The spring bearing this biasing force is the coil spring, and is accommodated in the spring accommodating hole of the case band of the timepiece armor main portion. Since this spring accommodating hole faces the axle fitting portion, the whole coil spring is substantially covered and concealed by the case band and the axle fitting portion such that the coil spring is not exposed to the outside of the timepiece armor main portion and, by covering the end portion of the coil spring in the vicinity of the axle fitting portion by means of the axle fitting portion, this end portion can be made so as not to protrude to the outside of the timepiece armor main portion. And, in case where the front lid biased in its closing direction is excessively opened for instance, the load applied accompanying this to the coil spring is proportional to the distance from the axle center of the pivot axle to the outer circumference face of the axle fitting portion, but there is no fact that the excessive force greater than the certain constant quantity is applied to the coil spring because the axle fitting portion is cylindrical.

- Hereunder, a 1st embodiment of the present invention is explained referring to FIG. 1-FIG. 4.
- In FIG. 1, a
sign 21 denotes a wristwatch, for instance, as a portable apparatus with opening/closing lid, and thiswristwatch 21 is formed while accommodating a timepiece movement 23 (refer to FIG. 2) as a built-in part in atimepiece armor assembly 22 as an apparatus armor assembly. - As shown in FIG. 2 and FIG. 3, the
timepiece armor assembly 22 has a timepiece armormain portion 25 as an apparatus armor main portion, afront lid 26 as an opening/closing lid, and acoil spring 27 for biasing thisfront lid 26 in its closing direction. - The timepiece armor
main portion 25 is formed while making a surface of the timepiece armormain portion 25 by bonding atransparent cover glass 32 to one face in thickness direction of its frame-like case band 31 by means of an adhesive, and making a back face of the timepiece armormain portion 25 by mounting, for example, an opaque metal-made case back 33 to the other face in thickness direction of thecase band 31. Thecover glass 32 covers a dial. - Although the
case band 31 is formed in an approximately annulus ring form by an opaque material such as a metal, in case where it is made a see-through type, thecase band 31 may be formed by a transparent synthetic resin. In FIG. 2 and FIG. 3, asign 34 denotes an annular rubber gasket for sealing. Incidentally, to thecase band 31 there are respectively attached a winding stem pipe (not shown in the drawing) while penetrating though a part of the case band in a radial direction, and a crown 35 (refer to FIG. 1) connected to a winding stem of thetimepiece movement 23 while being inserted into this pipe from an outside. - As shown in FIG. 4, in a position spaced by about 180° from the
crown 35 of thecase band 31, there are respectively provided a pivot axle supportingconvex portion 36 and, while being positioned in both sides of this, a pair of spring accommodating holes 37. To the pivot axle supportingconvex portion 36, there is attached penetrating in its width direction apivot axle 38. - As shown in FIG. 2 and FIG. 3, the
spring accommodating hole 37 is drilled in a thickness direction of thecase band 31 while extending in a direction perpendicular to an axis A (refer to FIG. 4) of thepivot axle 38. Each of thesespring accommodating holes 37 has a tapered hole bottom, and anopening 37 a opened to one face of thecase band 31 to which thecover glass 32 has been mounted. A center axis B of eachspring accommodating hole 37 deviates from an axle center C of thepivot axle 38 in a radial direction of thecase band 31. That is, in this embodiment, both of thespring accommodating holes 37 are provided while being biased toward an outside in the radial direction of thecase band 31 by a deviation dimension D with respect to the axle center C. - The
front lid 26 is made of, for example, a metal or synthetic resin, and has a circular shape somewhat smaller than thecase band 31. Thefront lid 26 is provided with a pair of axlefitting portions 41 protruding from its circumference edge. These axlefitting portions 41 have a short cylindrical shape of approximately the same shape as the axle supportingconvex portion 36. By inserting respectively end portions of thepivot axle 38 into each of a pair of axlefitting portions 41 disposed with the pivot axle supportingconvex portion 36 being placed between them, thefront lid 26 is attached so as to be rotatable about thepivot axle 38 with this being made a fulcrum. By this rotation, thefront lid 26 can move over an opened position exposing thecover glass 32 and a closed position covering and concealing thecover glass 32. - A pair of axle
fitting portions 41 attached while fitting to an outer circumference of thepivot axle 38 respectively faceopenings 37 a of thespring accommodating holes 37 so as to close them, and are disposed just above theopenings 37 a in FIG. 2 and FIG. 3. In an outer circumference face of theaxle fitting portion 41, there is provided one flat pressure-receivingouter circumference region 42 while forming a part of the outer circumference face. Additionally, within the outer circumference face of theaxle fitting portion 41, an outer circumference region 41 a, which faces the opening 37 a of thespring accommodating hole 37 accompanying the fact that thefront lid 26 is opened, is formed by an arc face continuous to the pressure-receivingouter circumference region 42. This outer circumference region 41 a becomes the arc face whose radius from the axle center C of thepivot axle 38 is an equal distance. In FIG. 2 and FIG. 3, asign 31 a denotes a clearance portion formed in thecase band 31 so as not to hinder a rotation of theaxle fitting portion 41. - In each
spring accommodating hole 37, there are accommodated thecoil spring 27, and atransmission body 45 supported by one end portion of thiscoil spring 27. Outer diameters of thecoil spring 27 and thetransmission body 45 are approximately equal to an inner diameter of thespring accommodating hole 37, and therefore center axes of thecoil spring 27 and thetransmission body 45 approximately coincide with the center axis B of thespring accommodating hole 37. Thecoil spring 27 is incorporated under its compressed state under which thetransmission body 45 is butted against the outer circumference face of theaxle fitting portion 41, and the other end is butted against the hole bottom of thespring accommodating hole 37. Therefore, a spring force of thecoil spring 27 is always given to theaxle fitting portion 41 through thetransmission body 45, and thereby thefront lid 26 is biased in its closing direction. Thetransmission body 45 has a pin-like form, its tip portion is formed in a convex curved face, e.g., hemispherical form, and it contacts with the outer circumference face of theaxle fitting portion 41 by this convex curved face. - As to the
wristwatch 21 having the above constitution, a state that thefront lid 26 has been closed so as to hinder a seeing of the dial is shown in FIG. 2. Under this state, the pressure-receivingouter circumference region 42 which is a part of the outer circumference face of theaxle fitting portion 41 faces so as to obturate the opening 37 a of thespring accommodating hole 37, and thetransmission body 45 is pressed to this pressure-receivingouter circumference region 42 by the spring force of thecoil spring 27. Therefore, thefront lid 26 receives a clockwise biasing force in FIG. 2, and is maintained in its closed state. In this case, since thetransmission body 45 is pressed to the flat pressure-receivingouter circumference region 42, a predetermined force is required in order that thetransmission body 45 is transferred to the outer circumference region 41 a, of theaxle fitting portion 41, consisting of the arc face beyond a corner portion denoted by asign 41 b in FIG. 2, so that thefront lid 26 is suppressed by a moderation of the predetermined force from being opened carelessly. - In order to see the dial, it is possible by counterclockwise opening the
front lid 26 by means of a hand with thepivot axle 38 being made the fulcrum. A state that thefront lid 26 has been opened is shown in FIG. 3. Under this opened lid state, the pressure-receivingouter circumference region 42 of the outer circumference face of theaxle fitting portion 41 is disengaged from thetransmission body 45, and the arc-like outer circumference region 41 a of theaxle fitting portion 41 contacts with thetransmission body 45. - Therefore, even if the
front lid 26 is greatly opened further, thecoil spring 27 does not generate excessively compressing by its motion, and it is possible that no large load is given to thefront lid 26. Cosequently, since thecoil spring 27 and an attaching portion of thefront lid 26 are suppressed from being injured and the spring force of thecoil spring 27 does not generate weak as well, it is possible to maintain the biasing function for thefront lid 26 by thecoil spring 27 for a long period of time. - In the
wristwatch 21 having the above constitution, as mentioned already, thecoil spring 27 biasing thefront lid 26 is accommodated in thespring accommodating hole 37 of thecase band 31. In particular, in this embodiment, thetransmission body 45 covers thecoil spring 27 from theaxle fitting portion 41 side. Accordingly, thecoil spring 27 is not exposed outside the timepiece armormain portion 25. Moreover, in this embodiment, since thecase band 31 and the like are opaque, it is possible that thecoil spring 27 and thetransmission body 45 in thespring accommodating hole 37 cannot be seen from an outside. Therefore, the decrease in the external appearance of thewristwatch 21 by thecoil spring 27 becomes null, so that it is possible to give a high grade sensation to thewristwatch 21. - In addition to this, as mentioned already, since the
coil spring 27 is not exposed outside the timepiece armormain portion 25, there is no fear that the end portion of thecoil spring 27 is caught by the user's finger and clothes, etc. in various handling, etc. during thewristwatch 21 is carried, so that it is desirable. - Additionally, since the biasing force of the
coil spring 27 is extended to theaxle fitting portion 41 through thetransmission body 45, it is easy to accurately determine the point of force of thecoil spring 27 with respect to theaxle fitting portion 41. By this, it becomes easy to suppress the dispersion of the biasing force for thefront lid 26, so that it is possible to stabilize a quality of thewristwatch 21. - FIG. 5A and FIG. 5B show a 2nd embodiment of the present invention. Since this embodiment has basically the same constitution as the 1st embodiment, the same sign as the 1st embodiment is applied as to the same constitution, and explanations of that constitution and the action are omitted and hereunder it is explained about different portions.
- In the 2nd embodiment, the
axle fitting portion 41 of thefront lid 26 is made a polygonal cylindrical form and, in its outer circumference face, there are continuously provided plural flat pressure-receiving outer circumference regions, e.g., pressure-receivingouter circumference regions 42 a, 42 b, in a circumferential direction of theaxle fitting portion 41. By this, acorner portion 43 is formed between the adjoining pressure-receivingouter circumference regions 42 a, 42 b. Incidentally, it is desirable to provide three or more flat pressure-receiving outer circumference regions. Further, in this 2nd embodiment, from a relation that the polygonal cylindrical body is adopted in theaxle fitting portion 41 usually brazed to the front lid, the flat faces forming a polygonal shape are provided in place of the outer circumference region consisting of the arc face, of theaxle fitting portion 41, adopted in the 1st embodiment, but it is also possible to make these portions by the arc faces. - The constitution other than that mentioned above is the same constitution as the 1st embodiment. Accordingly, also in the 2nd embodiment, the problem of the present invention can be solved similarly to the 1st embodiment. Moreover, in this 2nd embodiment, since the
axle fitting portion 41 has the polygonal cylindrical form, when opening or closing thefront lid 26, the momentary compression and release of thecoil spring 27 is performed every time thecorner portion 43 passes over the point of force of thecoil spring 27. By this, it is possible to give a definite click feeling. - FIG. 6A and FIG. 6B show a 3rd embodiment of the present invention. Since this embodiment has basically the same constitution as the 2nd embodiment, the same sign as the 2nd embodiment is applied as to the same constitution, and explanations of that constitution and the action are omitted and hereunder it is explained about different portions.
- In the 3rd embodiment, the
spring accommodating hole 37 is provided in thecase band 31 while being biased toward an inside in radial direction of thecase band 31 by the deviation dimension D with respect to the axle center C of thepivot axle 38. By this, it is formed such that the spring force of thecoil spring 27 accommodated in thespring accommodating hole 37 is exerted to theaxle fitting portion 41 through thetransmission body 45, and thefront lid 26 is biased counterclockwise in FIG. 6A and FIG. 6B, in other words, in a direction along which thefront lid 26 is opened. - Incidentally, in a portion, of the
case band 31, adjoining the crown, there is provided a push type lock button biased by a not-shown spring in a direction protruding from an outer circumference of thecase band 31 and, corresponding to this, a free end portion of thefront lid 26 is provided with an engaging portion engaged with or disengaged from the lock button. By closing thefront lid 26, the engaging portion engages with the lock button, so that thefront lid 26 can be maintained in its closed state. Conversely to this, by pressing the lock button, since the engagement between this button and the engaging portion is released, thefront lid 26 can be opened by the biasing force of thecoil spring 27. - Further, in the outer circumference face of the polygonal cylindrical
axle fitting portion 41 of thefront lid 26, 1st-3rd flat pressure-receivingouter circumference regions 42 a-42 c are continuously provided in the circumferential direction of theaxle fitting portion 41. By this, thecorner portions 43 are formed respectively between the mutually adjoining 1st, 2nd pressure-receivingouter circumference regions 42 a, 42 b and between the 2nd, 3rd pressure-receivingouter circumference regions - The constitution other than that mentioned above is the same constitution as the 2nd embodiment. Accordingly, also in the 3rd embodiment, the problem of the present invention can be solved similarly to the 2nd embodiment and, when opening or closing the
front lid 26, it is possible to give the definite click feeling. - The present invention is not limited to each of the above embodiments. For example, in an implementation as the watch, it can be applied also to a case where to a timepiece body main portion there is attached an opening/closing lid as a back cover for opening or closing a back face of the former, or a case where to the timepiece body main portion there are attached the opening/closing lid as the back cover for opening or closing the back face of the former together with an opening/closing lid for opening or closing a front face of the same, and the like.
- According to the present invention, since the coil spring biasing the opening/closing lid in a predetermined direction is not exposed outside the apparatus armor main portion, the external appearance can be improved and, since the end portion of the coil spring is not protruded to the outside of the apparatus armor main portion, there is no fear that the user's clothes and the like are caught by this end portion of the spring and, moreover since no excessive force is given to the coil spring even if the opening/closing lid is excessively opened in case where the coil spring-biases the opening/closing lid in its closing direction for instance, it is possible to provide the portable apparatus with opening/closing lid, in which the biasing function for the opening/closing lid by the spring can be maintained.
- According to the invention adapted such that the coil spring in the spring accommodating hole is covered and concealed from the axle fitting portion side by the transmission body, it is advantageous in a viewpoint of realizing the improvement in the external appearance and in a viewpoint of preventing the clothes and the like from being caught by the end portion of the spring and, since it is easy to accurately determine the point of force by the coil spring with respect to the axle fitting portion, it is possible to provide the portable apparatus with opening/closing lid, in which it is easy to suppress the dispersion of the biasing force for the opening/closing lid.
- According to the invention adapted such that no excessive force is given to the coil spring in case where the opening/closing lid is excessively opened, it is possible to provide the portable apparatus with opening/closing lid, in which no excessive load is given to the attaching portion of the opening/closing lid.
- According to the invention in which the plural flat pressure-receiving outer circumference regions continuous in the circumferential direction are provided in the outer circumference face of the axle fitting portion, it is possible to provide the portable apparatus with opening/closing lid, in which the definite click feeling is given on the occasion of the opening/closing motion of the opening/closing lid.
- According to the invention in which the portable apparatus with each opening/closing lid is realized as the watch, it is possible to provide the watch whose external appearance can be improved, in which the clothes and the like are not caught by the end portion of the spring biasing the opening/closing lid, and in which the biasing function for the opening/closing lid by the spring can be maintained.
- According to the present invention, since the coil spring biasing the front lid in the predetermined direction is not exposed outside the timepiece armor main portion, the external appearance can be improved and, since the end portion of the coil spring is not protruded to the outside of the timepiece armor main portion, there is no fear that the user's clothes and the like are caught by this end portion of the spring and, moreover since no excessive force is given to the coil spring even if the front lid is excessively opened in case where the coil spring biases the front lid in its closing direction for instance, it is possible to provide the timepiece armor assembly for watch, in which the biasing function for the front lid by the spring can be maintained.
