Metallic gasket |
摘要 |
A metallic gasket comprising a base plate having a first thickness-increased portion 3 formed at a peripheral edge on a combustion chamber opening 3 side of a base plate, and a first seal line SL1 and a second seal line SL2 arranged on the outer side of said first thickness-increased portion 3. No openings other than a cooling water hole 8 exist between said two seal lines. Beads formed along said seal lines SL1 and SL2 each 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. <IMAGE>
