Abstract:

PROBLEM TO BE SOLVED: To provide a laminated gasket which exerts favorable seal performance by a simple constitution in a fastening atmosphere in which the rigidity of a flange is lowered, a fastening load is lowered, and an in-bolt distance becomes long.SOLUTION: A laminated gasket grips and fixes an intermediate plate 3 between a pair of plate main bodies 2, 2 having annular beads 22, respectively, and seals flange faces by the annular beads 22 of a pair of the plate main bodies 2, 2 by the fastening of a fastening member between the opposing flange faces of an apparatus. A penetration hole 21 penetrated with a shaft part of the fastening member is formed at the plate main body 2, the intermediate plate 3 is extended to an external edge direction, the extended external edge is bent to the plate main body 2 side, and spacer parts 4 having magnitudes not hindering the sealing of the annular beads 22 are formed at the intermediate plate 3. Penetration holes 41 are formed at the intermediate plate 3 and the bent spacer parts 4 corresponding to penetration holes 23 of the plate main body 2.SELECTED DRAWING: Figure 2
