ABSTRACT:
A cylinder head gasket for an internal combustion engine is basically formed by first and second metal plates laminated together. The first metal plate includes a base portion, a first hole to be sealed formed in the base portion, a curved portion extending from the base portion to surround the first hole, a flange extending from the curved portion and located above the base portion, an annular portion formed in the flange immediately outside the curved portion, and a first bead formed in the flange outside the annular portion to project outwardly. The second metal plate is laminated on the base portion not to overlap with the flange.
