役目をさせている。Figure 1 shows a conventional metal gasket, which is inserted between the joint surface of the cylinder block and the cylinder head, and the cylinder head is fastened with bolts.
- is compressed to prevent gas and water from leaking from the joint surface. This metal gasket 1 has a cylinder hole 2 that forms a seal line for preventing leakage.
Beads 1:' 3, 6, and 7 are formed in the vicinity of the cooling water hole 4 and the oil hole 5, respectively, and their roles are to prevent gas venting, cooling water leakage, and oil leakage prevention, respectively. I'm letting you do that.

However, the surrounding surface area of the bead 6 formed in the vicinity of the cooling water hole 4 has been enlarged. In this embodiment, the bead 6 has conventional four cooling water holes 4.
A continuous bead 6 is formed around each of the four cooling water holes 4 and two ρ cylinder holes 2 inside the bead line 6 forming one continuous seal line.

可能となる。This configuration not only prevents the cooling water from leaking to the outside, but also prevents the cylinder block from forming in the area between the seal line formed by the bead 6 and the seal line formed by the bead 3 around the cylinder hole. 12 and cylinder head 14
Since cooling water can flow through the gap between the joint surfaces, a cooling effect can be expected. To explain this with a cross-sectional view, the conventional metal gas cooling water is sealed by forming a bead 1:6 around the cooling water hole 4 in Fig. 3, so the seal line 6-6 Cooling water can flow only in the area between the two. However, in FIG. 4 showing an embodiment according to the present invention, the cooling water flows between the outer seal line 6 of the cooling water hole 4 and the seal line 3 of the cylinder hole 2 7! It becomes possible to distribute to area b.
