Patent abstract
A metal gasket includes a first metal plate having a main full bead with bottom portions around a hole to be sealed, and a second metal plate laminated with the first metal plate on a depression side of the main full bead. The second metal plate has restricting members for restricting expansion of the bottom portions of the main full bead. Thus, when the gasket is compressed, lateral expansion of the main full bead is restricted to provide an appropriate surface pressure by the main full bead.
