Claims

[Claims for Utility Model Registration] (1) An exhaust outlet pipe that is removably attached to the muffler body is arranged inside the muffler body, and this exhaust outlet pipe is connected to the arrester body made of a cylindrical wire mesh,
A lid body fixed to one end of the arrester body,
and a cylindrical cap fixed to the other end of the arrester body, and the lid body is provided with a male screw inserted into the insertion hole provided in the lid body from inside the lid body, and the muffler body is provided with a male screw that is inserted from inside the lid body. By screwing into the female thread,
The mouthpiece is attached to the muffler body, and the mouthpiece is configured such that a protruding piece provided on the mouthpiece that expands radially outward is brought into contact with the inner circumferential surface of a cylindrical guide member provided on the muffler body. A muffler with a spark arrester attached to the muffler body above. (2) An engagement groove with a diameter smaller than the outer diameter of the threaded portion is formed at the lower part of the neck of the male screw, and the screw seat surface around the insertion hole of the lid body is formed in a conical shape that protrudes inward in the axial direction. , the screw seating surface is pressed against the muffler body and deformed into a flat plate shape by the screwing of the male and female screws, thereby contracting the inner diameter of the insertion hole and causing the inner peripheral edge to fit into the fitting. A muffler with a spark arrester according to claim 1, which is irremovably engaged in the axial direction with a matching groove. (3) An engagement groove with a smaller diameter than the outer diameter of the threaded portion is formed at the lower part of the neck of the male screw, and the male screw is inserted into the engagement groove of the male screw inserted into the insertion hole of the lid, so that the male screw can be removed from the insertion hole. A muffler with a spark arrester according to claim 1, in which a clip is engaged to prevent the spark arrester from causing a spark arrester.
