Abstract:
1. A gasket used for various kinds of objective members to be sealed, said objective remembers having the same outer shape and a plurality of differently figured bores, said gasket comprising: a metal base plate; a compound layer made of a synthetic resin or of a rubber material mixed with a fiber material, said compound layer being integrally laminated on at least one surface of said metal base plate; an outer frame and a partition frame formed inside of said outer frame for defining openings formed corresponding to said plurality of bores; a common bead structure for sealing, constituted by chevron-type full-beads, on whose opposite sides recess grooves are formed provided on said outer frame and at common portions of said partition frame, said chevron-type full beads of said common portion sealing such openings for bores that are not associated with the difference of shape of the bore due to the kinds of objective members; and a selective bead structure for sealing, constitute by a plurality of chevron-type full beads on whose opposite sides recess grooves are formed, provided at the other portions of said partition frames except said common portions thereof, at least one of said chevron-type full beads of said selective bead structure sealing such bores that are not sealed with said chevron-type full beads of said common bead structure, wherein: a sealing material made of a rubber material or of a synthetic resin is filled only into the grooves of said chevron-type full beads where said chevron-type full beads of said common bead structure and those of said selective bead structure are crossed or matched, thereby constituting an auxiliary sealing portion.
