ABSTRACT:
A metal gasket of the invention is used for an internal combustion engine. The gasket is formed of at least one metal plate for constituting the metal gasket. The gasket includes at least one bolt hole, and a bead having a main portion extending toward the bolt hole and an end portion located near the bolt hole. The end portion extending from the main portion changes a direction to incline in a direction away from the bolt hole. Accordingly, the end portion can be easily compressed when a bolt passing through the bolt hole is tightened. The plate with the bead may be combined with other plates to form a metal laminate gasket.
