Claims

[Scope of utility model registration request]

A tail pipe 3 that communicates with the inside of the muffler body 1 is inserted into the bottom surface 2a of a small recess 2 formed on the outer surface of the muffler body 1. A noise-reducing lid 5 is removably fitted and fixed so that an exhaust port 4 is formed between the tail pipe 3 and the periphery of the opening. This muffler structure for a small engine is characterized in that it is constructed by integrally forming a partition wall 5a that can form an exhaust passage 6 leading to an exhaust passage 6 in a zigzag shape.
