Abstract
A metal gasket for a cylinder head has a lamination of plates. The gasket includes two base metal plates each of which includes cylinder holes, circumferential beads formed around the peripheries of individual cylinder holes, cooling water holes formed outside the peripheries of the circumferential beads, and an outer bead formed so as to entirely enclose the circumferential beads and the cooling water holes. The circumferential beads of the two base plates are aligned in a direction of thickness of the gasket. Claw shaped protrusions are provided for one of an outer step adjustment metal plate and an inner step adjustment metal plate and extend from a cooling water jacket to the outer edges of the base plates into engagement holes in the other of the inner step adjustment plate and the outer step adjustment plate.
