ABSTRACT:
A steel laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket comprises a first plate and a second plate situated under the first plate. The first plate includes at least one first hole corresponding to the hole of the engine, a base portion, at least one curved portion and at least one flange situated above the base portion. The curved portion and flange are integrally formed with the base portion. A side wall is formed on one of the base portion and the flange to form an embossed portion thereat. Also, a bead is formed on the embossed portion to thereby provide a sealing pressure stronger than the embossed portion when the gasket is tightened.
