Abstract
A cylinder head gasket includes a first gasket base plate at a cylinder head side, a second gasket base plate at a cylinder block side, a shim that adjusts the gasket thickness, and a pressure increasing plate that increases the surface pressure at the side of periphery portions of the cylinders. In the first and second gasket base plates full beads are swollen at the side of periphery portions of cylinders, and half beads are swollen at a site outward of the full beads. The full beads of the first and second gasket base plates are formed so that top portions of the full beads face each other at positions that are opposite to each other in the up-down direction. The shim and the pressure increasing plate are sandwiched between the top portions.
