ABSTRACT:
A steel laminate gasket of the invention is situated for an internal combustion engine having at least one hole therein. The gasket comprises a first plate having at least one first hole corresponding to the hole of the engine and at least one first bead situated around the first hole, a second plate situated under the first plate, and a support device. The size of the support device is smaller than that of the first bead. The support device is situated beneath the first bead so that when the gasket is tightened, the support device abuts against and supports the first bead. As a result, the gasket can provide strong, even and wide sealing pressure.
