Claims

[Scope of utility model registration request]

The muffler main body 1 is divided by a separator 2 to form expansion chambers 6, 7, and 8 that are communicated with each other by a passage pipe 4, and the rear expansion chamber is expanded by passing through the front expansion chamber 6 and middle expansion chamber 7 in the axial direction of the muffler body. In a muffler comprising an introduction pipe 3 leading to a chamber 8, and a muffler tail pipe 5 that passes through a middle expansion chamber 7 and a rear expansion chamber 8 and releases exhaust gas from the front expansion chamber 6 into the outside air, The open end position of the muffler tail pipe 5 is extended to the lower part of the muffler body 1 which is lower than the introduction pipe 3 and the passage pipe 4, and only the upper half around the middle expansion chamber 7 position of the muffler tail pipe 5 having the open end is extended. A muffler structure characterized in that a large number of small holes 5a are bored in the muffler structure.
