CYLINDER HEAD GASKET AND METHOD FOR MANUFACTURING SAME

摘要

A cylinder head gasket (1) is provided with first and second base plates (3, 5) and an intermediate base plate (6), and combustion chamber holes (8) are formed in the base plates so as to correspond to the positions of the cylinder bores. Pressure increasing members (12) are provided between adjacent combustion chamber holes. In the direction in which the combustion chamber holes are arranged, each of the pressure increasing members (12) is exposed to the openings of the adjacent combustion chamber holes and is configured in such a manner that the thickness of the pressure increasing member (12) is uniform from one combustion chamber hole to the other. A load is concentrated between adjacent combustion chamber holes and a load is concentrated also in the openings of the combustion chamber holes. As a result, the sealing properties between the combustion chamber holes are satisfactory.
