ABSTRACT:
In a metallic gasket in which a plate member having at least one flexible metal plate has a hole, a flat portion formed at the periphery of the hole and a bead disposed concentrically with the hole to the outside of the flat portion is sandwiched between joining faces, an annular stopper is secured to the plate member at a position corresponding to the flat portion on the side of the hole. The stopper is made of a metal material different from the plate member and formed to an increased thickness at a portion for a larger gap, and formed to a decreased thickness at a portion for a smaller gap depending on the difference of the size of the gap between the joining faces.
