ABSTRACT:
In order to improve the sealing property and the resistance to pressure of a gasket coated with foam rubber layers, the foam rubber layers are formed on both surfaces of a metal plate from a rubber which is swollen by the medium to be sealed by the gasket, e.g. a rubber having an oil swelling property such as an NBR, is used. In this way the sealing property thereof is improved.
