ABSTRACT:
A gasket of the invention is installed between two engine parts of an internal combustion engine. The gasket may be formed of one metal plate including at least one first hole, at least one sealing device formed around the first hole, and a plurality of bolt holes for attaching the gasket to the engine. The metal plate further includes at least one second hole situated adjacent to the first hole between the two bolt holes, and a bead around the second hole. The second hole is arranged such that a substantial portion of the second hole is located outside an imaginary line linking between centers of the two bolt holes adjacent to each other. The bead includes an inner section near the first hole having spring constant weaker than a remainder of the bead. Therefore, when the metal plate is tightened between the engine parts, the bead can be compressed equally to securely seal around the second hole. The metal plate may be combined with other metal plates to constitute a steel laminate gasket.
