METAL GASKET

摘要

The present invention has an object to provide a metal gasket which enables improvement of sealing properties by making sufficient compression of a full bead possible even if elastic coating is formed along the full bead. In the gasket (1) having a full bead (13), formed on a metal substrate (10), having a mountain-shaped protruding surface formed on one side in a thickness direction and a valley-shaped recessed surface formed on the other side in the thickness direction, elastic coating (20) is formed on the whole surface of the protruding surface of the full bead (13), and the elastic coating (20) is formed on the recessed surface of the full bead (13), except a slit-shaped elastic coating-free section (14) along a bottom section (13a) of the recessed surface.

主权项

1. A metal gasket in which a full bead forming a mountain-shaped protruding surface on one side in a thickness direction and forming a valley-shaped recessed surface on the other side in the thickness direction on a metal substrate, characterized in that
elastic coating is formed on the whole surface of the protruding surface of the full bead; the elastic coating is formed on the recessed surface of the full bead except a slit-shaped elastic coating-free section along a bottom section of the recessed surface: the full bead is deformed by compression into a flat surface shape and generates a compressive reaction force when the metal substrate is attached between facing surfaces of counterpart members and fastened; and the elastic coating is brought into close contact with the counterpart member without a gap by the compressive reaction force of the full bead.
