Claims

[Scope of utility model registration request]

It is made up of at least three thin metal plates, first, second, and third, stacked on top of each other, and has a bore hole that matches the opening of the cylinder, a through hole that matches the opening of the water and oil hole, and a support inside the through hole. In the cylinder head gasket with a seal ring, the seal ring includes a core metal, a sealing material made of an elastic material reinforced by the core metal, and a sealing material integrally formed on the outer peripheral edge of the sealing material. and a locking protrusion integrally formed on one side of the tongue, and the locking protrusion is located near the through hole in a part of the first thin metal plate. A locking hole for elastically engaging the protrusion is formed, a relief hole or notch is formed in a part of the second thin metal plate that aligns with the locking hole, and a third thin metal plate The part of the tongue that aligns with the tongue piece is a thinned part, and the third thin metal plate does not overlap the first and second thin metal plates in that part. Metal cylinder head gasket with seal ring.
