内側縁部を折り返してグロメット部９を形成している。(Problem to be Solved by the Invention) As a gasket inserted between a cylinder block and a cylinder head of an internal combustion engine, it is especially important to seal the periphery of the cylinder opening 4, so in the case of a metal gasket. A ring-shaped bead 8 is formed on the peripheral edge of the cylinder opening 4, and a grommet portion 9 is formed by folding back the inner edge of the opening 4 of the sub-plate 2.

なるという問題点があった。In this case, the bead 8 improves the sealing performance due to the elasticity of its convex portion, and the grooves 21 to 9 improve the sealing performance by increasing the clamping pressure due to the increase in the plate thickness. Since the grommet part 9 is formed by avoiding plastic deformation of a metal plate, the thickness of the grommet part tends to be uneven and there is a risk of cracking, so it is necessary to control the surface pressure applied to the grommet part. In addition, the selection of materials is limited, and an additional mold incorporating the grommet portion is required for manufacturing.

In the metal gasket, a zone of an appropriate width at the peripheral edge of the cylinder opening of the secondary plate is divided from the rest of the secondary plate, and the plate thickness of the zone at the peripheral edge of the cylinder opening is different from that of the remaining part of the secondary plate. Make the plate thick and configure the metal gas Kent.

できる。(Function) As described above, in the present invention, in a metal gasket in which a sub-plate is sandwiched between a plurality of substrates, a zone of an appropriate width at the peripheral edge of the cylinder opening of the sub-plate is provided. Since it is divided from the rest, and the thickness of the zone around the opening for the cylinder is made different from the thickness of the rest of the sub-plate,
For example, by making the plate thickness of the peripheral edge of the cylinder opening a desired amount thicker than the thickness of the remaining part of the sub-plate, the surface pressure of the peripheral edge of the cylinder opening can be increased as desired.
すなわち本発明によれば、必要とする面圧を得るための
ガスケットの設計がきわめて容易になる。That is, according to the present invention, it becomes extremely easy to design a gasket to obtain the required surface pressure.
