A packing that prevents fluid flow between the first member and the second member by 2. The sealing surface that contacts each of the second members is constituted by a cylindrical surface perpendicular to the plane, and a recess is formed around the entire circumference at substantially the center of both end surfaces in the axial direction. . (2) The gasket according to claim 1, wherein the ratio of the distance between the sealing surfaces to the distance between the end surfaces is 2 or more. (3) The gasket according to claim 1 of the utility model registration, characterized in that a plurality of slits are carved in the radial direction of both end faces. (4) The gasket according to claim 1 of the utility model registration, characterized in that an inclined surface is formed at a corner where the both end faces and the sealing surface intersect.
