Claims

[Scope of utility model registration request]

A finisher is attached to the terminal end of a tail pipe extending from a muffler of an internal combustion engine exhaust system, with an air passage formed between the inner circumferential surface of the finisher and the outer circumferential surface of the terminal end of the tail pipe. In the muffler finisher mounting structure provided,
A damping mass damper is attached to the outer peripheral surface of the terminal end of the tail pipe, and a part of the mass damper is spaced apart from the outer peripheral surface of the tail pipe and protrudes outward to provide a damper-side mounting portion. A finisher mounting structure for a muffler, characterized in that the finisher is provided with a finisher-side mounting portion, and the damper-side mounting portion and the finisher-side mounting portion are tightened by a tightening mechanism to mount the finisher.
