An exhaust pipe assembly provided with a bellows pipe for connecting an upstream exhaust pipe and a downstream exhaust pipe is disposed so as to form a double pipe construction with a first joint pipe which is connected to the upstream exhaust pipe and a second joint pipe which is connected to the downstream exhaust pipe. A pair of ball receiving portions are disposed on a peripheral surface of the first joint pipe at a distance from each other in a circumferential direction, and a pair of ball receiving portions are disposed on a peripheral surface of the second joint pipe at a distance from each other in a circumferential direction. The ball receiving portions are disposed at an angular phase difference with each other in the circumferential direction. There is provided a coupling piece which has a pair of first ball joint portions engaged with the pair of ball receiving portions of the first joint pipe through a ball, and a pair of second ball joint portions engaged with the pair of ball receiving portions of the second joint pipe respectively through a ball.
