Claims

[Scope of utility model registration request]

(1) The casing constituting the muffler body, which has an exhaust gas inlet pipe and an exhaust pipe, is divided from approximately the center in the longitudinal direction, and the inner wall surface of each half casing is preformed and the surface is heat-resistant painted. A sound absorbing material made of asbestos-based inorganic material is attached, and the sound absorbing material is held down by a partition member that divides the internal space from the exhaust gas inlet to the exhaust port provided in the casing to form an exhaust gas flow path. . A muffler for an internal combustion engine, characterized in that the joint edges of the half-split casings are joined together by caulking.

(2) The partition member is formed of a sheet metal, and a joint piece is protruded from a suitable position of the partition member to penetrate through the sound-absorbing material and spot-weld to the inner wall surface of the casing. internal combustion engine muffler.
