<p>A cylinder head gasket (1) comprising: a pair of gasket base sheets (4, 5) including combustion chamber holes (8) and full beads (4a, 5a) surrounding the combustion chamber holes (8); a intermediate sheet (6) disposed between the pair of 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 (4b, 5b) surround the full beads and are not positioned over the shim sheet. A water hole (10) is formed outside a region surrounded by the first half beads, and furthermore the first half beads are spaced apart from each other at locations close to the combustion chamber holes in a state where a centerline connecting the centers of the combustion holes is disposed between the first half beads. A cooling liquid is not allowed to flow into the spaces between neighboring full beads so as to prevent the separation of a coating.</p> |
