Claims

[Scope of utility model registration request]

In a muffler in which a silencing chamber is formed by an inlet side outer plate and the other side outer plate, an inlet hole is formed in the inlet side outer plate, and an exhaust outlet is formed in either one of both outer plates,
A throttle member that forms an exhaust passage together with the inner peripheral wall of the entrance side outer plate is fixed to the inner peripheral wall of the entrance side outer plate,
and one end of the throttle member communicates with the inlet hole, while forming an exhaust passage port in the throttle member that communicates the exhaust passage and the muffling chamber,
A partition guide that partitions the silencing chamber and forms a U-shaped passage from the exhaust passage port to the exhaust exit is fixed between the throttle member and the exhaust outlet, and the partition guide is connected to the first side plate facing the first side plate. 1. A muffler comprising a second side plate and a sound absorbing material filled between the first and second side plates, and wherein one of the side plates is made of a breathable material.
