To provide a pipe fitting for exhaust pipes capable of absorbing the translational displacement of the upstream exhaust pipe and downstream exhaust pipe with each other.
A gasket 18 installed between a first flange 11 and a second flange 12 is furnished with a first seal surface 18A abutting to the first flange 11 slidably, a second seal surface 18B abutting slidably to the peripheral surface 22B of the downstream exhaust pipe 22 (second exhaust pipe), and a load receiving surface 18C parallel with the second flange 12, wherein the first 18A and second seal surfaces 18B are pressed and urged resiliently to the first flange 11 and the peripheral surface 22B by a leaf spring 30 (energizing means) installed between the second flange 12 and the load receiving surface 18C of the gasket 18.
