Abstract
A cylinder head gasket 1 has a gas seal plate P1 in which a combustion chamber hole 11 is drilled, an oil seal plate P2 in which an oil hole 13 is drilled, and a main plate P3 provided between the gas seal plate and the oil seal plate. Plate thicknesses of the gas seal plate, the oil seal plate, and the main plate are made different from each other, the plate thickness of the gas seal plate is larger than the plate thicknesses of the oil seal plate and the main plate, and end portions of the gas seal plate, the oil seal plate, and the main plate are connected to each other. A combustion gas, lubricant oil or the like from a combustion chamber or an oil passage can be effectively sealed, and the cylinder head gasket can be manufactured inexpensively.
