ABSTRACT:
The thickness of an intermediate plate portion (31b) is smaller than the thickness of a stopper portion (31a). The thickness of a portion of a cylinder head gasket (20) having the stopper portion (31a) is set to be greater than the thickness of other portions of the cylinder head gasket (20). Before the cylinder head gasket (20) is provided between contact surfaces (12a, 13a), a space (S) is formed between the stopper portion (31a) and an adjustment stopper portion (32a), and the intermediate plate portion (31b) partially contacts the adjustment plate portion, and a bead (33a) contacts the adjustment plate portion (32b).
