    • A flexible tube for an automobile exhaust system which has a bellow assembly to absorb the first exhaust pipe and the second exhaust pipe for the an exhaust system having a cylindrical outer cover (5) made of plate to cover the outer periphery of the bellows (3)1 the first collar (7') and the second collar (7") with the risers (7a', 7a") bent toward the inner surface (5a) of the outer cover (5); the first elongation displacement stopper member (6') and the second elongation member displacement stopper member (6") respectively formed by bending the inner side of the outer cover (5); and the first elastic stopper member (8') and the second elastic stopper member (8") provided at the risers (7a', 7a") of both collars (7', 7"). As a further modification, the second outer cover (9) may be provided inside of the outer cover (5) to form displacement stoppers (9a, 9b) by bending the both end portions of the second outer cover.
