It is an object to fix a catalytic body (175), which has a cylindrical case (176) and is housed in an exhaust pipe (152), to the exhaust pipe (152) that serves as part of an exhaust system connected to an engine, the catalytic body (175) can be housed in and fixed to the exhaust pipe (152) even if the case (176) of the catalytic body (175) and the exhaust pipe (152) are made of different materials, thus increasing the freedom in choosing materials for the case of the catalytic body (175) and the exhaust pipe (152). <??>In the invention, a bracket (178), which is made of the same material as an exhaust pipe (152), is welded to an inner circumferential surface of the exhaust pipe (152), and the bracket (178) is crimped on a case (176) of a catalytic body (175). <IMAGE>
