Description of the Related Art A laminated metal gasket in which a first and a second plate are superposed on each other to form a gasket base material has a cylinder hole formed therein, and a folded portion for preventing gas leakage from the cylinder hole. A metal ring is provided in the portion, and the gas ring is prevented by the metal ring such that the sealing surface pressure is intensively generated in the folded portion as compared with the portion other than the folded portion.

ることがある。In the conventional example, when a folded portion provided with a metal ring is compared with a portion other than the folded portion, gas leakage occurs due to a concentrated seal surface pressure at the folded portion. Although it can be prevented, depending on the position of the tightening bolt (bolt hole in the case of gasket) or the relationship between the part between cylinder holes and other parts, etc.
It is not necessary for the entire area of the folded portion to generate a uniform sealing surface pressure, and the generation of the sealing pressure may rather be a cause of gas leakage.

It was created to provide a certain product.

ものである。A gasket material is constituted by a first plate and a second plate which are superimposed on each other, and the first plate is folded back on the second plate side without overlapping the second plate. Providing a folded portion constituting a hole, between the folded piece constituting the folded portion and the first plate, at least a part of the outer peripheral edge,
A metal ring having a wide portion is interposed, and the wide portion of the metal ring is engaged with a concave edge provided on an inner peripheral edge surrounding the cylinder hole of the second plate.

いだ製品を提供できる。[Effects] Since the wide portion of the metal ring reduces the tightening load of the tightening bolt, the folded portion where the wide portion is located has a reduced seal surface pressure as a whole, and the reduced portion is folded. The gasket can be provided with a well-balanced seal surface pressure distribution as a whole, distributed to the other parts of the part, and the wide part of the metal ring is engaged with the concave edge so that the metal ring is Since it does not rotate (move) along the periphery of the metal ring, it is possible to provide a product that reliably prevents gas leakage due to the rotation of the metal ring.

A portion 8 of the wide portion 6a, which is disposed closer to the narrow portion 6b and protrudes from the folded portion 4, is connected to the cylinder hole 3 of the second plate 2.
