ABSTRACT:
A metal laminate gasket of the invention is installed in an internal combustion engine with a hole to be sealed. The gasket is basically formed of first, second and third metal plates laminated with each other, and a grommet to seal around the holes of the engine. The grommet includes an upper portion and a lower portion with different lateral length. A main sealing section defined by the upper and lower portions and the first and third plates is formed around the hole of the engine, while a resilient sealing section is formed outside the main sealing section. The resilient sealing section is defined by the upper portion of the grommet, a bead on the first plate, and the second and third plates. The surface pressures at the main and resilient sealing sections can be easily controlled.
