ABSTRACT:
A metallic gasket comprising a base plate having a first thickness-increased portion3formed at a peripheral edge on a combustion chamber opening3side of a base plate, and a first seal line SL1and a second seal line SL2arranged on the outer side of said first thickness-increased portion3.No openings other than a cooling water hole8exist between said two seal lines. Beads formed along said seal lines SL1and SL2each consist of a convex metal bead raised only upward from an upper surface of said base plate and a rubber bead made of an elastic sealing material fixed to a convex portion and a concave portion of said metal bead. This structure of said metallic gasket can improve a processing accuracy of said metal bead and also enhance cooling effects on said metallic gasket itself and said joint surfaces of an engine, between which said metallic gasket is disposed.
