い等の欠点があった。A convex or stepped bead is formed on an elastic metal plate, and this bead allows internal combustion engines, for example,
A metal gasket that efficiently seals the joint surface between a cylinder head and a cylinder block has already been completed and filed by the inventor of this application. This metal gasket is constructed by laminating a base plate made of an elastic metal plate and sub-plates provided on both the front and back sides of this base plate, and the deck surface is formed by the bolt tightening force between the cylinder head and the cylinder block. It has already been made public that a seal line is formed on the joint surface to ensure close contact and achieve an outstanding sealing effect. However, this metal gasket has the disadvantage that when the sealing performance caused by the beads provided on the substrate is too strong, it damages the cylinder head and cylinder block, which are the mating surfaces of this metal gasket. In addition, the strength of the surface pressure exerted by the communicating seal line of the bead on the mating surface may be extremely uneven depending on the location, and in this case, a gap may be created.
There were drawbacks such as the inability to achieve effective sealing throughout the bead.

Since the rise of the second bending part 30 is steep and the rise of the second bending part 30 is gradual, the contact area between the first bending part 28 and the second sub-plate 10 is large, and the second bending part 30 and the first The contact area with the sub-plate 8 becomes smaller. Therefore, the surface pressure generated on the first auxiliary plate 10 by the restoring force of the bead 4 is small on the first auxiliary plate 8-)2, and locally large on the second auxiliary plate 10. Become. For this reason, by arranging the third sub-plate 12 on the back side of the second sub-plate 10 as in the first embodiment, the surface pressure transmitted to the cylinder block 18 is reduced and averaged.

The blood pressure on the front and back sides of the metal gasket is approximately equal, and the sealing effect of the metal gasket is improved. Also, since the hardness of the sub-plate that comes into contact with the mating surface is softer than the substrate, there will be no thermal distortion, tool marks, scratches, etc. on the joint surface. Ii US is possible, so
A good micro-sealing effect can be achieved.
