るエンジンのサイレンサー構造。 An exhaust guide pipe is provided passing through a resonance chamber formed in the silencer shell in the form of a closed container, and a resonance passage having a predetermined cross-sectional area and passage length is provided in a portion of the exhaust guide pipe corresponding to the resonance chamber. The exhaust guide pipe has a two-piece structure consisting of a first pipe body and a second pipe body that are fitted into each other in the axial direction at a position facing the resonance chamber. and the first
The first tube, which is fitted on the radially outer side of the tube and the second tube, has the second tube fitted on the inside thereof.
A convex strip that bulges outward in the radial direction is formed at a portion that becomes a fitting joint to the tube body, spanning the entire axial length of the fitting joint, and the first tube body and the second tube body are fitted together. In the inserted and joined state, the protrusion and the corresponding second
A silencer structure for an engine, characterized in that the resonance passage is constituted by a gap formed between the tube body and the outer circumferential surface of the tube body.
