Abstract:
A metal gasket of the invention is used for an internal combustion engine. The gasket is formed of at least one metal plate extending substantially throughout an entire area of the engine to be sealed, and includes a plurality of fluid holes including cylinder bores and liquid holes. Double beads are formed in the metal plate and located around at least one of the fluid holes. The double beads are an inner bead and an outer corrugated bead surrounding the inner bead to securely and widely seal around the fluid hole. The outer corrugated bead provides surface pressures partly differently when the corrugated bead is compressed, to thereby seal around the fluid hole and to support the pressure applied thereto.
