Referring to FIG. 5A, the fan blade 113 according to the present embodiment is inclined to have an angle of −α (counterclockwise) with respect to the horizontal direction. When the fan blade 113 having such a configuration rotates clockwise together with the rotation of the first rotating plate 112, the opposite direction of gravity is caused by the rotation of the fan blade 113 as shown by the solid arrow of FIG. 6.
