シリンダヘツドガスケツト。 A metal cylinder head gasket is made by laminating two thin metal plates and has a plurality of bore holes, through holes for passing liquid, and a plurality of small circular holes for inserting bolts. The thickness of the first thin metal plate exposed on one side of the first thin metal plate is larger than the thickness of the second thin metal plate exposed on the other side,
The first metal thin plate is folded back 180 degrees at least in a part of the peripheral edge of the cylinder head gasket to form a folded part having a thickness of two first metal thin plates, and the first metal thin plate is not overlapped with this folded part. a through hole in at least one of the first thin metal plate and a second thin metal plate that is laminated on the first thin metal plate and has a through hole having a larger diameter than the bore hole formed in the first thin metal plate; In the part located around the first,
An annular protrusion higher than the difference in thickness between the second thin metal plate is formed on the inner peripheral edge of the bore hole of the first thin metal plate, and the second thin metal plate is thinner than the second thin metal plate. A metal cylinder head gasket characterized by being equipped with a grommet made of a thin metal plate that is thicker than one-half the thickness of the thin metal plate.
