Patent ID: 7793942

Claim:
A metal gasket comprising: a first metal plate having a main full bead around a hole to be sealed, said main full bead having bottom portions from which the main full bead directly rises upwardly, and a flat surface around the hole at a side opposite to a side that the main full bead rises; and a second metal plate laminated with the first metal plate on a depression side of the main full bead, said second metal plate having restricting members for receiving the bottom portions of the main full bead when the gasket is compressed, wherein said first and second metal plates are made to fit in shapes of engine members to be installed, and said first metal plate is configured such that the bottom portions are located above the restricting members when the first metal plate is placed on the second metal plate without applying pressure thereto, and the bottom portions project toward the second metal plate and directly engage the restricting members only when the gasket is compressed to restrict lateral expansion of the main full bead to thereby provide an appropriate surface pressure by the main full bead.
