Metal laminate gasket with continuous bead

摘要

A metal gasket is formed by a bead plate provided with a continuous bead, and an outer plate partly bent around combustion chamber holes to laminate the metal plates together. The bead has a linear common portion situated in an intermediate area between two cylinder bore holes, curved surrounding portions diverging from the linear common portion near the one second hole to partly surround the cylincder bore and water hole, and a curved linking portion extending between the curved surrounding portions to partly surround the water hole. The water hole is completely surrounded by the parts of the curved surrounding portions and the curved linking portion.
