Claims

[Scope of utility model registration request]

This sealing device consists of a cylinder rad gasket 1 and a seal ring 8 installed in a through hole 4 as a water hole or an oil hole bored in the cylinder rad gasket 1. A support frame 9 that has a similar shape to the through hole 4 and is slightly smaller than the through hole 4, and this support frame 9.
and a backing 10 that fits around the outer periphery of the support frame 9. The thickness of the support frame 9 is at least as large as that of the cylinder
A seal device characterized in that when the gasket is installed between the upper surface of the cylinder block and the lower surface of the cylinder head, the thickness of the gasket is equal to or less than that of a sheet constituting the gasket.
