ABSTRACT:
A seal rubber3is placed in a first peripheral groove2formed in one main surface1A of an approximately flat-plate-shaped metal body1. A second peripheral groove4and multiple communicating holes5to communicate between the second peripheral groove4and the first peripheral groove2are formed in the other main surface1B of the metal body1. A retaining rubber6disposed in the second peripheral groove4, the seal rubber3, and a bridge rubber7disposed in the communicating hole5are integrated. The first peripheral groove2is made to be a dovetail groove, the second peripheral groove4is made to have an inner surface inclined to reduce the groove width from a groove opening side to a groove bottom surface side, and the groove width D4-2of the groove bottom surface and the inner diameter D3of the communicating hole5are made to be substantially the same. As a result, release or breakage of the seal rubber does not occur during opening or closing of the two members, stable seal performance is achieved, and even when a large seal is to be made, the seal rubber can be attached easily.
