Claims

[Claims for Utility Model Registration] (1) Three thin metal plates, first, second, and third, are stacked together to form a bore hole that matches the opening at the top of the cylinder, and the top surface of the cylinder block and the cylinder head are connected to each other. In order to form the above-mentioned bore hole in a metal cylinder head gasket that is used while being sandwiched between the lower surface and the lower surface, a second hole formed in an intermediate second thin metal plate is also connected to the bore hole. In order to form a A seal ring, which is an annular body formed of heat-resistant rubber and whose inner peripheral surface side is covered with a metal plate, is installed at a position outside the hole, sandwiched between the first and third thin metal plates. A metal cylinder head gasket featuring: (2) Instead of directly sandwiching the seal ring between the first and third thin metal plates, a support plate connected to the outer peripheral edge of the seal ring is sandwiched between the first and third thin metal plates, The metal cylinder head gasket according to claim 1, wherein the seal ring is exposed inside the first and third holes. (3) The metal cylinder head gasket according to claim 1, wherein instead of the seal ring, a wire ring is attached, in which a surface layer of chromium or nickel is formed on the surface of an iron core material with a copper intermediate layer interposed therebetween.
