Abstract
A metallic gasket, such as for an internal combustion engine, wherein an elastic metallic plate has a pair of combustion chamber holes therethrough in adjacent relationship. Annular sealing beads are formed on the gasket in surrounding relationship to the combustion chamber holes. The beads are disposed closely adjacent so that they substantially overlap in the region between adjacent holes. At the junctions where the adjacent beads meet, the bead width is approximately equal to the bead width in the region between the junctions and in the remaining annular parts of the beads.
