、メタルシリンダヘツドガスケツト。 It is made by laminating two thin metal plates, the first and the second.
Metal cylinder head gaskets that have a bore hole, a through hole for passing lubricating oil or cooling water, and a plurality of small circular holes for inserting bolts are made of hard material such as stainless steel or spring steel. A through hole having a larger diameter than the bore hole is formed at a position aligned with the bore hole of the first thin metal plate, and is made of a semi-hard material such as stainless steel or high carbon steel, and is made of a semi-hard material such as stainless steel or high carbon steel. The peripheral edge of a through hole smaller in diameter than the bore hole, which is formed at a position that matches the bore hole in the second metal thin plate which is also thicker,
A grommet is formed by folding the grommet 180 degrees without overlapping with the first thin metal plate, and the inside of this grommet is made into a bore hole, and both the first and second thin metal plates located around the through hole are provided with a grommet. A metal cylinder head gasket, characterized in that a protrusion is formed to surround the entire circumference of the through hole.
