Abstract
A metal laminate cylinder head gasket is formed by a plurality of metal plates laminated together, and a misalignment preventing portion for preventing misalignment of the laminated metal plates, formed in the metal plates. The misalignment preventing portion includes a pair of notches facing each other and penetrating each of the metal plates, and a bridging portion provided between the notches in each of the metal plates and bulging in one direction to project from a surface of each of the metal plates. The metal plates are laminated together such that the notches and the bridging portions overlap and closely contact to engage together to thereby prevent displacement of the metal plates.
