ABSTRACT:
A metal gasket in which a thin metal plate for reinforcing the beads of an elastic metal plate is laminated on bead regions only of the elastic metal plate, whereby a stable sealing performance is secured for a long period of time. This metal gasket comprises a thin metal plate provided with beads extending around the circumferences of parallel arranged combustion chamber holes, and an elastic metal plate having combustion chamber holes and extending with a predetermined width and laminated on the portions of the thin metal plate which are around the combustion chamber holes so as to be opposed to valley portions of the beads. The thickness of the thin metal plate is set smaller than that of the elastic metal plate. The thin metal plate is fixed to the elastic metal plate with locking portions formed at the outer circumference of the former engaged with slits formed in the regions of the latter which are on the outer sides of the beads, the thin metal plate being combined with the elastic metal plate at joint portions thereof by spot welding or laser welding.
