WIPO Patent Application WO/2016/088524
Kind Code:
A1
Abstract:
Provided is a seal ring capable of being manufactured at low cost by injection molding and capable of reducing the amount of leakage of fluid. A seal ring is integrally formed in an annular overall shape, which has a cutout at one circumferential location, using a thermoplastic resin composition. The seal ring has a ring body and also has a first protrusion (21) and a second protrusion (22), which are provided protruding in the circumferential direction from a first end and a second end of the ring body. The transverse cross-section of the ring body is rectangular, the transverse cross-section of the second protrusion (22) is triangular, and the first protrusion (21) has a slope conforming surface (23) parallel to the sloped surface (24) of the bottom side of the triangle of the second protrusion (22). The first protrusion (21) and the second protrusion (22) are dimensioned so as not to protrude from a basic rectangular shape when the first protrusion (21) and the second protrusion (22) are overlapped and the cut is closed.
