Claims

[Claims for Utility Model Registration] 1 Several expansion chambers 11, 17, 18, an outlet pipe 14 whose upstream end opens to the most downstream expansion chamber 17 among these expansion chambers, and a catalytic converter 13 a main muffler 21 which is attached to the engine and has several expansion chambers 11,
a flexible pipe 25 whose one end opening communicates with one of the expansion chambers 17 and 18;
An internal combustion engine-mounted muffler comprising a resonance chamber 30 that communicates with the opening at the other end of the flexible pipe 25 and is formed separately from the main muffler 21. 2. The resonance chamber 30 is equipped with a bracket 31,
2. The internal combustion engine-mounted muffler according to claim 1, wherein the muffler is mounted on a frame member or body of a motor vehicle using the bracket and disposed within an engine rule. 3. Claim 1, wherein the resonance chamber 30 is made of resin.
Or the internal combustion engine-mounted silencer described in 2.
