Exhaust pipe joint assembly

摘要

An exhaust pipe assembly (1) provided with a bellows pipe (13) for connecting an upstream exhaust pipe (2) and a downstream exhaust pipe (5) is disposed so as to form a double pipe construction with a first joint pipe (14) which is connected to the upstream exhaust pipe (2) and a second joint pipe (15) which is connected to the downstream exhaust pipe (5). A pair of ball receiving portions (141, 141) are disposed on a peripheral surface of the first joint pipe (14) at a distance from each other in a circumferential direction, and a pair of ball receiving portions (151, 151) are disposed on a peripheral surface of the second joint pipe (15) at a distance from each other in a circumferential direction. The ball receiving portions (141, 141 / 151, 151) are disposed at an angular phase difference with each other in the circumferential direction. There is provided a coupling piece (16) which has a pair of first ball joint portions (161, 161) engaged with the pair of ball receiving portions (141, 141) of the first joint pipe (14) through a ball (17), and a pair of second ball joint portions (162, 162) engaged with the pair of ball receiving portions (151, 151) of the second joint pipe (15) respectively through a ball (17). <IMAGE>
