Abstract:
A metal gasket for sealing two parts, comprising:one metal gasket member extending substantially throughout an entire area of the parts and having a bead and two outer surfaces to contact the parts, at least two elongated seal coatings coated on the two surfaces of the gasket member to be spaced apart from each other to sandwich the bead therebetween without overlapping the bead to thereby constitute sealing lines on the surfaces of the gasket member, said sealing lines being arranged so that one of the sealing lines on one surface of the gasket member is laterally shifted from the other of the sealing lines on the other surface of the gasket member without providing the seal coatings on immediate opposite sides of the gasket member, respectively, and micro coatings coated on the two surfaces of the gasket member without overlapping the seal coatings and having a thickness less than that of the seal coating.
