Claims

[Claims for Utility Model Registration] (1) A plurality of elastic metal plates having beads protruding in the same direction formed at corresponding positions, such that the protruding directions of the beads are aligned and the corresponding beats are overlapped with each other. In the gasket, the width of the bead is made wider as the bead is formed on the metal plate disposed on the protruding side of the bead, and the height of the bead is set on the plurality of metal plates. 1. A metal gasket characterized in that the beads are substantially the same, and the radius of curvature of the rising base of the bead is made smaller as the bead is formed on a metal plate disposed on the protruding side of the bead. (2) A gasket including a plurality of metal plates in which a plurality of elastic metal plates each having beads formed at corresponding positions and projecting in the same direction are stacked so that the corresponding beads overlap each other with the protruding directions of the beads aligned. The width of the bead is made substantially the same for the beads formed on the plurality of metal plates, and the height of the bead is made higher for the bead formed on the metal plate disposed on the protruding side of the bead, and A metal gasket characterized in that the radius of curvature of the rising base of the bead is made larger as the bead is formed on a metal plate disposed on the protruding side of the bead. (3) A gasket including a plurality of metal plates in which a plurality of elastic metal plates each having beads formed at corresponding positions and projecting in the same direction are stacked so that the corresponding beads overlap each other with the protruding directions of the beads aligned. In this method, the width of the bead is made wider for the bead formed on the metal plate disposed on the protruding side of the bead, and the height of the bead is made wider for the bead formed on the metal plate disposed on the protruding side of the bead. 1. A metal gasket characterized in that the radius of curvature of the rising base of the bead is made smaller as the bead is formed on a metal plate disposed on the protruding side of the bead.
