CYLINDER HEAD GASKET

PROBLEM TO BE SOLVED: To provide a cylinder head gasket capable of preventing a cooling liquid from flowing into spaces between full beads and full beads in a case where the full beads are separated from each other.SOLUTION: The cylinder head gasket 1 includes: a pair of gasket base sheets 4, 5, in which combustion chamber holes 8 and full beads 4a, 5a surrounding the combustion chamber holes 8 are formed; an intermediate sheet 6 disposed between the pair of the gasket base sheets; and a shim sheet 7 disposed between the intermediate sheet and one of the gasket base sheets. The shim sheet 7 is positioned over the full beads, and first half beads 4b, 5b are formed on the gasket base sheets at locations such that the first half beads surround the full beads and are not positioned over the shim sheet. Water holes 10 are formed outside a region surrounded by the first half beads, and furthermore the first half beads are separated from each other at locations where the combustion chamber holes are close to each other in a state where a centerline connecting the centers of the combustion holes is disposed between the first half beads. According to this invention, the separation of a coating can be prevented by preventing the cooling liquid from flowing into the spaces between the full beads adjacent.
