ABSTRACT:
The present invention relates to a metal gasket for sealing the joint surfaces of the cylinder head and the cylinder block of an internal combustion engine. The metal gasket comprises a plural number of metal plates and an annular rigid resin layer, each of the metal plates having opening(s) corresponding to the combustion chamber hole(s) of the gasket and bolt holes. The plural number of the metal plates are laminated so as to be overlaid on each other. The first metal plate disposed on the side of one outer surface of the gasket has a bent portion formed by turning back the peripheral portion of its opening, the bent portion having a curved portion and a flange portion. The bent portion encloses the peripheral portion of the opening of the second metal plate which is one of the metal plates laminated. The annular rigid resin layer is formed of, e.g., an epoxy resin. The rigid resin layer is disposed on either the surface of the second metal plate confronting the first metal plate or the inner surface of the first metal plate, or on one of the surfaces of the metal plates laminated between both of the above surfaces, so as to surround the combustion chamber hole. The thickness of the part of the gasket in which the rigid resin layer is disposed is larger than that of the remaining part of the gasket.
