Claims

[Scope of utility model registration request]

In a silencer in which an inlet pipe and an outlet pipe are inserted into a shell whose openings at both ends are sealed by end plates, the inlet pipe or outlet pipe with a small hole is inserted into the shell. accommodating two cylindrical bodies, the ends of these cylindrical bodies are closed, and the outer peripheral surfaces of these cylindrical bodies are brought into contact with each other on opposite sides to form a mutual contact part, and The outer circumferential surfaces of the equal cylindrical bodies are brought into contact with the inner circumferential surface of the shell on the outside, and small holes are bored in the outer circumferential surfaces of the cylindrical bodies on opposite sides of the mutually contacting portion. The silencer is further characterized in that one of these cylindrical bodies is depressed at the mutually contacting portion, and a communication portion is formed in the mutually contacting portion.
