Abstract
A metal gasket of the invention is used for an internal combustion engine having a plurality of cylinder bores therein. The gasket is formed of at least one metal plate. The metal plate includes a plurality of holes corresponding to the cylinder bores, and at least one intermediate portion between the holes adjacent to each other. A plurality of beads is formed around the respective holes. The width of the bead at the intermediate portion is narrower than that at the rest of the bead, and the height of the bead at the intermediate portion is higher than that at the rest of the bead. Thus, the bead at the intermediate portion provides a sufficient surface pressure to seal thereat.
