Claims

[Scope of utility model registration request]

A muffler body is formed by pressing two press-molded outer plates facing each other in close contact with each other, and a muffler body is formed by pressing two plates with press-formed grooves facing each other in close contact with each other, and is fixed within the muffler body to form the grooves. A muffler for an internal combustion engine, comprising a dual-purpose member in which a portion is used as an exhaust passage and a flat part other than the groove is used as a partition wall partitioning the inside of the muffler main body, the pipe being formed by a perforated plate having a sound absorbing material attached thereto. A muffler for an internal combustion engine, characterized in that a sound deadening member formed by winding is held between two plate members constituting the dual-purpose member.
