A catalytic converter support structure for an exhaust pipe

The present invention provides a catalytic converter support structure for an exhaust pipe, which is a support structure effective for vibration of a vehicle body while ensuring ease of assembly and disassembly of the catalytic converter, and is also simple in structure and miniaturized. The intermediate portion of the exhaust pipe (54) that connects a cylinder head and a muffler is divided, and an outer cylinder (92) of a catalytic converter (57) using a catalyst to purify the exhaust gas is disposed across the end faces (81c, 82c) of the exhaust pipe (54). Further, one of the front exhaust pipe (81) and the rear exhaust pipe (82) (the front exhaust pipe (81)) before and after the end faces (81c, 82c) is provided with a front enlarged diameter portion (81b) that fixes one end of the outercylinder (92). Further, the other of the front exhaust pipe (81) and the rear exhaust pipe (82) (the rear exhaust pipe 82) is held at the other end of the outer cylinder (92). The outer cylinder (92)is detachably attached to
