Claims

[Scope of utility model registration request]

An expansion chamber and a resonance chamber are defined inside the cylindrical body with both ends of the outer cylinder closed, the outside of the cylindrical body and the expansion chamber communicate with each other through an inlet pipe and an outlet pipe, and the expansion chamber and the resonance chamber communicate with each other through a resonator pipe. In the silencer, the inlet pipe and the resonator pipe are fitted in the expansion chamber, and
A silencer characterized in that a large number of small holes are bored in the peripheral wall of the inlet pipe near the fitting part.
