Claims

[Scope of utility model registration request]

In a metal cylinder head gasket, which is made by laminating three or more 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 first method is to change the height of the annular protrusion surrounding the bore hole on the middle thin metal plate, and the height of the annular protrusion surrounding the bore hole at both ends and the protrusion strip around the middle bore hole. The thickness of both ends is made thicker than the thickness of the middle part by at least one of the second means of forming protrusions only around the small circular holes located at both ends of the circular hole. A metal cylinder head gasket featuring:
