ABSTRACT:
A metal laminate gasket of the invention is used for an internal combustion engine. The gasket is formed of first and second metal plates extending substantially throughout an entire area of the gasket. The first plate includes a main portion, a curved portion for defining a first hole, and a flange extending from the curved portion. The second plate is situated under the main portion of the first plate, and includes a second hole in which the curved portion is located, an inner portion situated around the second hole and disposed on the flange, and a recess formed in the inner portion around the second hole to form a thin portion. At least one bead is formed on at least one of the first and second metal plates to surround the hole of the engine to seal the same. The surface pressure of the gasket around the hole can be adjusted by regulating the thickness of the thin portion.
