<p>[Technical Problem] It is an object to provide a metal gasket in which a sealing performance that is equal to or greater than that of the prior art can be obtained by using less tightening force than used in the prior art. [Solution of Problem] An annular metal gasket for sealing a space between members by being pressed in the vertical direction in a state of being mounted between the members, the metal gasket comprising an annular outer ring having a substantially C-shaped cross-section and having a circumferential-direction opening formed therein, and an annular inner ring fitted inside the outer ring. The inner ring is formed so as to have a polygonal cross-section comprising an upper corner part that makes contact with an upper side of an inside surface of the outer ring, a lower corner part that makes contact with a lower side of the inside surface of the outer ring, an inner-circumference-side corner part formed on an inner-circumference side of the inner ring so as to be positioned between the upper corner part and the lower corner part, and an outer-circumference-side corner formed on an outer-circumference side of the inner ring so as to be positioned between the upper corner part and the lower corner part. Bend parts having an inner angle larger than 180° are formed between the upper corner part and the inner- and outer-circumference-side corner parts; and between the lower corner part and the inner- and outer-circumference-side corner parts.</p> |
