Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a diaphragm arranged in an inner pipe from breaking due to a thermal stress inside a connection part, in an arrangement in which the connection part inserted and fitted to an flange is provided at an end on an upstream side of a two-passage double exhaust pipe connected to an exhaust manifold. SOLUTION: The diaphragm 4 is provided in a diameter direction inside an inner pipe 2. In the connection part 5 inserted and fitted to the flange 6, the inner pipe 2 is formed into a circle and an outer pipe 5 is formed into an ellipse, and a clearance 13 is provided between the two pipes. Accordingly, though the diaphragm 4 is exposed to heat of the highest temperature to considerably thermally extend in a width direction, resistance against the thermal extension is reduced due to provision of the clearance 13, whereby the stress can be reduced.
