一のシール効果を低減させるという不都合がある。In addition, during use, as the deck surface gap around the combustion chamber increases or decreases due to combustion pressure, an alternating load acts on the bead of the metal gasket, causing it to sag, and this alternating load also acts on the fastening bolts. There is a risk of damaging the bolt and the part of the cylinder that engages with Pole I.Furthermore, the tightening force of the bolt may be reduced and the metal gasket 1 may be damaged.
This has the disadvantage of reducing the first sealing effect.

Therefore, it is possible to compensate for irregularities in the deck surface gaps of the cylinder head, particularly around the combustion chamber, which occur when the cylinder head is fastened, thereby preventing combustion gas, etc. from entering from the large gaps around the combustion chamber. Further, it is possible to prevent the metal gasket from being contaminated by intruding combustion gas or the like and from reducing the sealing effect due to the accumulation of contained substances. Furthermore, the alternating load acting on the bead is weakened to prevent the bead from sagging, thereby preventing damage to the fastening bolt and the cylinder head portion to which this bolt engages, and reducing the fastening force of the fastening bolt. th can be prevented and a stable sealing effect can be obtained. Furthermore, since the compensation part is formed on the substrate without adding any other parts, the structure can be simplified, the metal gasket can be easily installed, and the cost I can be reduced.
