<p>A cylinder head gasket (10, 10A) is formed of a metal plate (11, 11A), cylinder bore sealing devices (22) formed on the metal plate for sealing around cylinder bores, and at least one water hole sealing device (23, 23A, 23B) formed on the metal plate. The water hole sealing device has an inner sealing portion (23a, 23Aa, Ba) extending along and outside the cylinder bore sealing devices to have a space thereto and extending outside the water holes on a side of the cylinder bores, and an outer sealing portion (23b, 23Ab, 23Bb) situated outside the water holes and extending along the inner sealing portion. The inner and outer sealing portions surround a plurality of water holes (13) therein, and continuously extend to join together to have at least one gas releasing portion (17, 17A, 17B) between end portions of the water hole sealing device. Thus, even if the combustion gas leaks from the cylinder bores, the gas can be prevented from entering the water holes. <IMAGE></p> |
