摘要： A gasket includes an annular gasket base and an outer circumferential seal that adheres along an outer circumferential edge portion of the gasket base. The outer circumferential seal includes a sandwiched portion that is sandwiched between opposing end surfaces of two members together with the gasket base, and a bulging rim portion that bulges outwards from outer surfaces of the two members over the whole circumferences of the outer surfaces, when the gasket base is sandwiched between the opposing end surfaces of the two members.

摘要： 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.

摘要： An object of the present invention is to provide a water jacket spacer that can prevent cooling water from entering the space between the water jacket spacer and a bore side inner wall face of a water jacket by a simple structure and can facilitate mounting work into the water jacket. Provided is a water jacket spacer 1 that is inserted into a water jacket 102 and regulates the flow of cooling water flowing into the water jacket 102 from a cooling water inflow port 105a. The water jacket spacer 1 includes a first seal lip 13 that is arranged on the upper end of a spacer main body 10 and is in contact with a bore side inner wall face 102a of the water jacket 102 to seal a gap formed between the bore side inner wall face 102a and the spacer main body 10.

摘要： A sealing apparatus using a gasket in which a gasket main body is integrally formed with a reinforcing ring, the gasket main body has a one-end-side seal bead and an other-end-side seal bead which are positioned on one end side and another end side of the reinforcing ring in an axial direction and are oriented in directions facing away from each other in the axial direction, the one-end-side seal bead is closely contacted on a bottom surfaced of an attachment recessed part formed in a housing, and the other-end-side seal bead is closely contacted on a cover which closes the attachment recessed part of the housing, wherein in a state of being attached in the attachment recessed part with the cover removed from the housing, at least a part of an outer peripheral portion of the gasket serves as a supportable portion by providing a flange consecutively provided on an outer periphery side of the reinforcing ring.
