Metallic gasket

A metallic gasket comprising a base plate made of a thin metal plate, said base plate having at least a combustion chamber opening and a cooling water hole, and having a first thickness-increased portion made of metal and increased in thickness and encircling a peripheral edge of said combustion chamber opening, a first bead formed on the outer side of said first thickness-increased portion of said base plate in a manner to endlessly encircle said combustion chamber opening, and a second bead formed on the outer side of said first bead in a manner to endlessly encircle said combustion chamber opening and said cooling water hole,

• wherein in a region of said base plate between said first bead and said second bead, there are no holes other than said cooling water hole, and each of said first and second beads is a composite bead of a metal bead and a rubber bead, wherein said metal bead is formed only on one surface side of said base plate by bending said base plate in a through-thickness direction to create a convex portion higher than the height of said first thickness-increased portion, wherein said rubber bead is formed of an elastic sealing material fixed to said convex portion side surface of said metal bead and filled in a concave portion on the reverse side of said convex portion and said rubber bead is compressed and deformed in the through-thickness direction in cooperation with deformation of said metal bead, and wherein said elastic sealing material on the surface of said convex portion side is fixed at least to the surface of said convex portion of said metal bead and is arranged to have a height equal or substantially equal to the height of said metal bead, further a second thickness-increased portion is provided at an outer peripheral edge of said base plate.
