Abstract:
A metal laminate gasket to be arranged between two members includes a first metal plate and a second metal plate laminated together. The first metal plate has a first hole to be sealed, a first bead around the first hole, and a plurality of second holes around the first bead as bolt holes. The second metal plate has a third hole and fourth holes corresponding to the first and second holes, respectively, and depressions formed at a side facing the first metal plate around the third hole. Each of the depressions is formed on two sides of a line connecting a center of the third hole and a center of each of the fourth holes so that a compressing force of the bead when the gasket is compressed becomes substantially equal around the first hole.
