  • Patent number: 10612660
    Abstract: The invention provides a gasket having sealing lips in axial both ends of a gasket body in which a reinforcing ring is embedded. The gasket, has a structure in which the gasket body is displaced to the one axial side within the mounting groove when pressure acts on the gasket because the rigidity of a second sealing lip is set to be higher than the rigidity of a first sealing lip or a reinforcing ring is disposed closer to the one axial side within the gasket body. Furthermore, a seal bead which is brought into close contact to the bottom surface of the mounting groove when mounted is provided in the gasket body and a space portion surrounded by the second sealing lip, the seal bead, and the bottom surface and the other side surface of the mounting groove when mounted is provided.
