管部の消音構造。[Claims for Utility Model Registration] 1. In an exhaust system in which a bellows pipe 7 for vibration absorption is inserted in the middle, the outer diameter of the exhaust inlet pipe 8 that introduces exhaust gas into the bellows pipe 7 is set to the bellows shape of the bellows pipe 7. The exhaust inflow pipe 8 is extended inward from the exhaust inflow side of the bellows pipe 7 so as to substantially match the inner diameter of the portion 7a, and the bellows shaped part 7
A small hole 12 that communicates with the inside of the exhaust inflow pipe 8 from a cavity 11 formed by the inner wall of the a and the outer peripheral wall of the exhaust inflow pipe 8 is connected to the exhaust inflow pipe. 8. A bellows pipe part noise reduction structure in an exhaust system, characterized in that several rows of bellows pipes are arranged on the peripheral wall of the exhaust system. 2. Request for registration of a utility model characterized in that the bellows tube 7 has a cylindrical portion 7b formed at the rear of the bellows-shaped portion 7a, and an r' inner cylinder 8' is fitted inside the cylindrical portion 7b. A sound deadening structure of a bellows pipe portion in an exhaust system according to item 1.
