MUFFLER, MUFFLER DEVICE PROVIDED THEREWITH, AND DAMPERS

摘要

Disclosed is a muffler device whereby the vibration of a muffler is suppressed regardless of the natural frequency of the body of said muffler. Said muffler device comprises: a muffler (2); two exhaust pipes (Pi and Po), the ends of which are connected to the muffler (2); and a support part (3) that supports the muffler (2). The muffler (2) comprises: a muffler body (20) in which an expansion chamber (2a) for reducing noise propagated via the pipes (Pi and Po) is formed; and damper mechanisms (D) that contain large numbers of granular bodies (D0) that move in response to vibration of the muffler body (20), thereby attenuating said vibration.
