摘要： PROBLEM TO BE SOLVED: To reduce weight without lowering the durability of a connecting structure of an exhaust pipe connecting by using a bellows. SOLUTION: In the connecting structure of the exhaust pipe connecting two exhaust pipes by the bellows, accordion portion curves on axial direction both end sides of the bellows are bent outward in a radial direction, and axial direction both end cylindrical portions of the bellows are integrally welded on an outer surface of the exhaust pipe with a reinforcing ring. The reinforcing ring has an end part inner surface of an axial direction bellows accordion part side with an R-shaped or tapered axial cross section, and an axial direction bellows accordion part side end surface of the reinforcing ring is positioned so as not to contact with the bellows accordion part.
