<p>A metallic gasket (10) comprises: a pair of bead plates (14) which has cylinder holes (12) corresponding to cylinder bores and also has full beads (22) for surrounding the cylinder holes; a first intermediate plate (18) disposed between the pair of bead plates; and a shim plate (16) disposed in regions around the cylinder holes so as to be disposed between the first intermediate plate and one of the bead plates. The thickness of contact sections (19) of the first intermediate plate, said contact sections (19) being in contact with the shim plate, is varied in the circumferential direction of the cylinder holes, and circular arc-shaped slits (23) for surrounding the outer sides of the contact sections, the thickness of which is varied, are formed in the first intermediate plate. The thickness of the contact sections (19) is varied in the circumferential direction of the cylinder holes (12) to obtain an optimum contact pressure force, and the amount of bending of the first intermediate plate caused by the formation of the contact sections (19) can be reduced by the slits (23).</p> |
