ンサ構造。[Scope of Claim for Utility Model Registration] (1) A silencer with a flat shape whose height is lower than its width, in which a predetermined range is provided at the center of a flat-shaped outer cylinder member whose height is lower than its width. An exhaust pipe member having a large number of holes formed therein is inserted into the exhaust pipe member, and plate members whose upper and lower ends are connected to the upper and lower surfaces of the outer cylindrical member are spaced apart from each other in the width direction on both sides of the exhaust pipe member. A silencer structure characterized in that a heat insulating/sound absorbing member is filled between a side portion of the outer cylinder member and the plate member. (2) The outer cylindrical member has upper and lower surface portions whose widthwise center portions protrude inward to form upper and lower protrusions;
The silencer structure according to claim 1, wherein an exhaust pipe member is fixedly supported by the upper and lower protrusions.
