Claims

[Scope of utility model registration request]

The exhaust gas flowing in the exhaust gas pipe is led into the room from the front small outlet holes formed in a large number on the circumferential wall of the exhaust gas pipe, and the exhaust gas in the room is guided into the room through the small number of small holes in the front formed on the circumferential wall of the exhaust gas pipe. In a silencer equipped with an expansion chamber in which the exhaust gas is introduced into the exhaust gas conduit again from the rear introduction hole, the outlet small hole and the introduction hole formed in the exhaust gas conduit have a hole diameter of A noise-reducing mouth characterized by being configured to have different characteristics.
