Claims

[Claims for Utility Model Registration] An upstream exhaust pipe 10 connected to the engine side of an automobile and a downstream exhaust pipe 20 connected to the muffler side are connected, and the relative relationship between the two exhaust pipes 10 and 20 is The exhaust pipe joint allows angular displacement and relative axial displacement, and (a) the upstream exhaust pipe 10 has a cylindrical sliding member 30 and a packing 40 fitted on the outer peripheral surface of the pipe end. That's what I'm doing. (b) A first packing presser 5 is provided at one end of the packing 40 and includes a cylindrical portion 51 and a diameter-reduced cylindrical portion 53 having a diameter reduced by the cylindrical portion 51 and a shoulder portion 52.
0 is disposed such that the cylindrical portion 51 is fitted onto the outer peripheral surface of the end of the packing 40 and the shoulder portion 52 is brought into contact with the end surface of the packing 40. (c) At the other end of the packing 40, there is a second packing presser 6 that includes a cylindrical portion 61 and a reduced diameter cylindrical portion 63 that has a reduced diameter with the cylindrical portion 61 and a shoulder portion 62.
0 fits the cylindrical portion 61 onto the outer circumferential surface of the end of the packing 40, brings the shoulder portion 62 into contact with the end surface of the packing 40, and places the reduced diameter cylindrical portion 63 on the outer circumferential surface of the sliding member 30. be arranged so that they fit together. (d) Reduced diameter cylindrical portion 6 of the second packing presser 60
3. The outer peripheral surface has a convex spherical surface part 71 on the outer surface, a through hole 72 on the inner surface, and a flat surface part 73 on the large diameter side of the convex spherical surface part 71.
A seal body 70 is provided with a seal body 70 that fits the through hole 72 into the outer circumferential surface of the reduced diameter cylindrical portion 63 and
3 is placed in contact with the shoulder portion 62. (e) The downstream exhaust pipe 20 has a concave spherical part 21 at its end and a cylindrical part 2 connected to the concave spherical part 21.
2 is formed, the concave spherical surface portion 21 is brought into sliding contact with the convex spherical surface portion 71 of the seal body 70, and the cylindrical portion 2
2 surrounding the outer peripheral surface of the upstream exhaust pipe 10. (f) Between the downstream exhaust pipe 20 and the first packing holder 50, there is a coil spring 80 biased with a spring force so as to constantly press the packing 40 toward the distal end of the upstream exhaust pipe 10. be arranged. An exhaust pipe joint characterized by the configurations a to f above.
