Metal gasket

A metal gasket which is interposed between a cylinder head and a cylinder block and provides a seal therebetween, the metal gasket comprising:

• an elastic metal substrate provided with a bead on a cylinder opening peripheral portion;
• a thin metal plate thinner than the elastic metal substrate, a part of the thin metal plate being arranged at a convex portion side of the bead, the thin metal plate being fixed in an outside area of the bead of the elastic metal substrate,
• wherein the thin metal plate and the elastic metal substrate are deformed into a convex portion or a concave portion which continues in a first direction by a press working and are deformed into a cut concave portion or a cut convex portion in a second different direction from the first direction.

A metal gasket which is interposed between a cylinder head and a cylinder block and provides a seal therebetween, the metal gasket comprising:

• an elastic metal substrate provided with a bead on a cylinder opening peripheral portion;
• a thin metal elate thinner than the elastic metal substrate, a part of the thin metal elate being arranged at a convex portion side of the bead, the metal thin plate being fixed in an outside area of the bead of the elastic metal substrate,
• wherein the thin metal plate and the elastic metal substrate are mutually coupled at a mutual biting portion between metals, to which a surrounding portion of a deformed base portion deformed by a press in the thickness direction is side by side.
