Claims

[Claims for Utility Model Registration] (1) In a muffler that is installed in the middle of an exhaust pipe of an engine and has a cylindrical part with a larger diameter than the exhaust pipe, the sound range is located at a position facing the exhaust pipe in the cylindrical part. A silencer comprising: a control means; and a sound absorbing member disposed within the cylinder portion at a position facing the sound range control means. (2) Utility model registration claim 1, characterized in that the sound range control means is formed by overlapping a large number of hollow pipes whose dimensions change substantially continuously.
Silencer as described in section. (3) The silencer according to claim 1, wherein the sound range control means is formed of a porous member.
