ABSTRACT:
A metal gasket excellent in sealing performance and capable of sealing with a small pressing force. The metal gasket comprises at least one metal sheath with a C-shaped cross-section and a ring elastic core surrounded by the metal sheath. The metal gasket provides a seal upon exertion of a force in the axis center direction. The metal sheath has a locally thin cross-section over the whole annular length, and when the metal sheath subject to a force and deformed, the deflection in the axis direction of the metal sheath due to concentrated stress on the thin worked portion causes the formation projections at both sides of the deflection which projections are pressed onto the sealing face to form air-tight seals.
