Abstract
A metallic gasket includes two elastic metal base plates and a thinner subplate disposed between the inner sides of the base plates, wherein at least two cylinder bore holes are perforated in each of the base plates and subplate, a bead protrudes outward from each base plate at the periphery of each cylinder bore hole by way of a flat area, and a linear bead joining the beads for both of the adjacent cylinder bore holes is formed between the adjacent cylinder bore holes. The subplate includes an essentially circular circumferential edge portion present only at the periphery of each of the cylinder bore holes and a continuous portion between adjacent cylinder bore holes. The subplate is secured to the circumference at the inner side of one of the base plates at a portion of the flat area of the base plate near the cylinder bore hole, the outer circumferential end at the peripheral edge of the subplate is varied within the bead width of the base plate and a linear bead that can be contained within the linear base plate bead is formed only in the continuous portion of the subplate.
