PURPOSE: Structure of a clamp for an exhaust pipe is provided to seal the connection portion of the exhaust pipe efficiently by the annular clamp, and to improve flow of exhaust gas by inserting the additional connecting member to the connection part of both exhaust pipes. CONSTITUTION: An annular dam is protruded in the end of a front pipe to connect exhaust pipes(20a,20b), and an expansion part is formed in the end of the rear pipe to surround the dam. The dam is surrounded by the expansion part, and the connection portion is bound with the annular clamp. A cylindrical member(30) is inserted to the inner periphery of the connection portion of the exhaust pipes, and a fixing groove(26) is formed in the inner periphery of the rear exhaust pipe and spaced from the expansion part. A fixing projection(33) is formed in the rear part of the cylindrical member, and fitted to the fixing groove. The cylindrical member is composed of an outer cylinder(31) and an inner cylinder(32). Grooves(34a,34b) are formed in the inner periphery of the outer cylinder, and projections(35a,35b) are formed in the outer periphery of the inner cylinder.
