Abstract

In order to provide a metal gasket suitable for use for a flange made of synthetic resin, the metal gasket disposed between a resin flange and an aluminium flange is composed of two elastic metal plates, on each of which a half bead is formed, and which are superposed on each other to be jointed so that half beads are directed opposite to each other.Since bending in a state, where the gasket is tightened, can be suppressed to an extremely small value at a same level in the case where the flanges are tightened without gasket, it is possible to remove worsening in flatness (planarity) of the resin flange.
