摘要

A cylinder head gasket arranged between a cylinder head and a cylinder block in an internal combustion engine. The cylinder head gasket has a core web of steel with hooks arranged between facing sides of a pair of gasket plates made of a heat resistant resilient material, such as asbestos or graphite. Grommet rings are fitted to edges of openings in the web and the gasket plates aligned corresponding to the respective cylinder bores. The web has regions adjacent to the inner periphery of the aligned openings and located substantially inside of the grommet member rings, the regions containing no hooks, or containing hooks having a reduced height.
