Document Type and Number:
WIPO Patent Application WO/2017/002800
Kind Code:
A1
Abstract:
Provided are a gasket, a spherical joint, and an exhaust pipe with excellent workability in assembly work and capable of preventing the occurrence of noises. A gasket (4): is a cylinder having a large diameter end face (40), a small diameter end face (41), and a spherical outer circumferential surface (42); is formed from reinforcing material such as wire mesh and a heat-resistant material such as expanded graphite; and is used in spherical joints (1) for connecting car exhaust pipes (2a, 2b). The inner circumferential surface (44) of an insertion hole (43) of the gasket (4) into which an exhaust pipe (2a) is inserted is configured so as to be elastically deformable in the radial direction by alternately disposing interference sections (45), which provide interference with respect to the exhaust pipe (2a), and clearance sections (46), which form clearances with respect to the exhaust pipe (2a), in the circumferential direction.
