ABSTRACT:
A metal laminate gasket of the invention seals between two engine parts with holes. The gasket is basically formed of a first plate and a second plate situated above the first plate. The first plate includes a groove formed around a hole to be sealed, which includes an inlet portion and two inclined side walls. The second plate includes a bead formed around the hole to be sealed, which includes two base portions and two side portions. When the first and second plates are assembled, the side portions of the bead abut against the side walls of the groove. When the gasket is tightened, the side portions of the bead are pushed against the side walls of the groove to seal therebetween, and surface pressures are formed at the base portions of the bead around the groove to securely seal between the engine parts.
