Abstract
In a metallic gasket having a metallic sheet made with a recess surrounding around a diverse type of hole, in which an elastic sealing member is installed, a relation between the recess and the elastic sealing member in their cross sections and also configurations is so specified as to use the elastic sealing member within a range of elastic limit inherent in the elastic sealing member, thereby improving the sealing performance of the metallic gasket. The elastic sealing member is smaller than the recess in their cross section perpendicular to the major side of the metallic sheet. Thus, the elastic sealing member, when the metallic gasket is squeezed, may serve its useful function within the range of inherent elastic limit.
