PROBLEM TO BE SOLVED: To improve an assemblability, manufacture a joint in a compact size and lightweight, and reduce a cost. SOLUTION: An inner joint 2 is formed on the downstream end part of an upstream exhaust pipe H1, and an outer joint 3 is formed on the upstream end part of a downstream exhaust pipe H2. The upstream exhaust pipe H1 and the downstream exhaust pipe H2 are connected to each other by a bellow tube 4, and displacement controlling means 6, 6 for the bellow tube 4 are provided on a connected part of the inner joint 2 and the outer joint 3. The displacement controlling means 6, 6 are provided with balls 6A, 6A. Caps 6D, 6D by which the balls 6A, 6A are respectively received are specially provided on the inner surface of the outer joint 3 in a peripheral direction. On the outer surface of the inner joint 3, a groove 6B is formed as a ball receiving part for receiving balls 6A, 6A.
