Patent ID: 8459657

Claim:
A metallic gasket comprising: a base plate made of a thin metal plate, said base plate having at least one opening; beads, each bead formed along a seal line; and a first thickness-increased portion made thicker than the remaining base plate, wherein each bead comprises, in combination: a metal bead formed by bending said base plate in a through-thickness direction to create a single convex portion, the single convex portion having opposing inclined surfaces on only one surface side of said base plate, the metal bead having a height higher than the thickness-increased portion; and a rubber bead made of an elastic sealing material, the rubber bead having a first portion disposed on the inclined surface of the convex portion facing the first thickness-increased portion a second portion disposed in a concave portion of the metal bead opposite said convex portion, and a third portion disposed on the inclined surface of the convex portion of the metal bead opposite the inclined surface on which the first portion of the rubber bead is disposed, wherein the thickness of the first portion of the rubber bead is substantially equal to an overall height of the metal bead, wherein a top surface of the first portion of the rubber bead is substantially parallel with a flat surface of the only one surface side of said base plate, wherein the rubber bead having the first portion the second portion, and the third portion is configured to be compressed and deformed in the through-thickness direction by interacting with a deformation of the metal bead, and wherein the first portion of the rubber bead extends toward the thickness-increased portion such that a side surface of the first portion opposite the metal bead is disposed between and a distance from both an edge of the first thickness-increased portion nearest the metal bead and an end of the metal bead nearest the first thickness-increased portion.
