Abstract:
A gasket, comprising:a gasket member extending substantially throughout an entire area to be sealed, said gasket member having a first hole to be sealed and a plurality of second holes for allowing bolts to pass therethrough situated around the first hole, a compressible sealing member disposed on at least one side of the gasket member to completely surround the first hole adjacent thereto without surrounding the second holes, and a hard coating formed of a material different from those of the gasket member and the compressible sealing member and disposed on at least said one side of the gasket member to surround the second holes, said hard coating being formed independently from the compressible sealing member and having compressibility less than that of the compressible sealing member so that a reduction of compressibility around the second holes in use is suppressed, said hard coating being spaced from the compressible sealing member with a gap therebetween and formed in each of areas around the second holes to be spaced from each other.
