Claims

[Scope of utility model registration request]

The exhaust gas passage that penetrates the resonance chamber formed in the sealed casing in the flow direction of the exhaust gas is constituted by a porous sintered metal pipe, and the wall layer of the porous sintered metal pipe has a large number of small holes. A silencer for an engine, characterized in that a hole is formed, the small hole and the ventilation hole created by the porous material are used as a port of the resonance chamber, and the inside of the resonance chamber is filled with a sound absorbing material.
