Abstract

A resonance device (28) which is provided in an exhaust device (23) having a silencer (27) that silences sound of exhaust gas from an engine (21) and which silences a specific frequency sound includes: an exhaust pipe (34) which is provided downstream of the silencer (27) in an exhaust flow direction and whose first end portion (34a) is connected to the silencer (27); an inner pipe (35) connected to a second end portion (34b) of the exhaust pipe (34) and having at least one penetration hole (35a); and an outer pipe (36) that is attached to the inner pipe (35) so as to surround a periphery of the inner pipe (35) and that defines, together with an outer periphery of the inner pipe (35), space that forms a resonance chamber (37). An outer periphery of the second end portion (34b) of the exhaust pipe (34) is inserted into the inner pipe (35) so that a step (39) is formed at a connecting portion between the second end portion (34b) and the inner pipe (35).
