Document Type and Number:
Japanese Patent JP5782551
Kind Code:
B2
Abstract:
Provided is a seal ring manufactured from a mixture containing a soft resin including at least one of a thermoplastic elastomer and a dynamic crosslinked resin, and a hard resin including a thermoplastic resin. With this seal ring, the adhesion to the inner peripheral surface of a housing can be maintained in a no-load state where a hydraulic pressure is not generated even after use as a one-piece type for an extended period of time and oil leakage can be effectively prevented. The mixture constituting the seal ring preferably has a compression permanent deformation of 95% or lower after immersion in an automatic transmission fluid at 150°C for 100 hours.
