摘要： PROBLEM TO BE SOLVED: To provide a cylinder head gasket in which horizontal displacement between an opening-side end portion of a grommet and a gasket substrate is prevented, thereby preventing reduction of a sealing performance in that portion.SOLUTION: A cylinder head gasket 1 comprises a plurality of gasket substrates 11-13 which are laminated mutually, and in the gasket substrates, combustion chamber holes 11a-13a and bolt holes 11b-13b are formed, respectively. A grommet 14 is provided to cover inner edges of all the combustion chamber holes 11a-13a, and opening-side end portions 14a, 14b of the grommet 14 are fixed to the gasket substrates 12 and 13 in contact with the grommet. Thus, even when displacement in a horizontal direction occurs between a cylinder head and a cylinder block, since the opening-side end portions of the grommet are fixed to the gasket substrates, horizontal displacement therebetween can be prevented, thereby maintaining an excellent sealing performance for a long time.
