Abstract:
A piston includes a piston main body and a seal ring. The seal ring has a metal ring including a fitting tube portion fitted to a cylinder portion of the piston main body and a flange portion extending radially to axially oppose a pressure receiving portion of the piston main body, and a rubber-like seal main body provided on the metal ring. The seal main body has a first seal lip contacting an inner surface of a clutch cylinder, a second seal lip extending from an end of the flange portion to contact the pressure receiving portion, and an axial direction compression seal portion provided on the flange portion and compressed toward the pressure receiving portion.
