Claims

[Scope of utility model registration request]

A concave spherical seal seat 2 whose diameter increases toward the end and a flange 3 are integrally provided at the pipe end of one exhaust pipe 1, and are arranged opposite to the exhaust pipe 1 of the other exhaust pipe 4. A seal ring 5 having a convex spherical surface portion 5a corresponding to and in sliding contact with the concave spherical seal seat 2 is provided on the outer circumferential surface of the end of the tube. A pressing block 6 that presses the exhaust pipe 4 is slidably arranged in the axial direction of the exhaust pipe 4. One end of the pressing block 6 and the exhaust pipe 1 is fixed to the pressing block 6, and the other end is inserted through the flange 3. The exhaust pipe 1 is connected by a pair of headed bolts 7 disposed as shown in FIG. and
One end of a bellows-like pipe 9 is fixed to the pressing block 6, and the bellows-like pipe 9 surrounds the outer peripheral surface of the exhaust pipe 4 and extends in its axial direction, and the other end is fixed to the exhaust pipe 4. An exhaust pipe joint characterized by:
