Abstract
The metal gasket according to the present invention is formed by bead base plates comprising elastic metal plates having beads and auxiliary beads along the circumferences of holes, and an intermediate plate interposed between these bead base plates. The stoppers and stepped portions formed on the intermediate plate prevent the total compression of the beads on the bead base plates when the metal gasket is tightened, and enable the irregularity of the opposed surfaces of a cylinder head and a cylinder block to be offset. The auxiliary beads provided on the bead base plates display the sealing performance with respect to the beads and minimize the dead spaces around the holes.
