Abstract
An object of the present invention is to provide a gasket capable of ensuring an excellent sealing property by a pair of seal beads oriented in directions axially opposing to each other, regardless of an inserting direction of the gasket into a setting groove. The object is achieved by a gasket in which: an axial length of a reinforcement ring () is formed to have a length such that the other axial end of the reinforcement ring () approaches an end surface of the other mating member or an end surface of a setting groove () in a state that one axial end of the reinforcement ring () contacts the end surface of the setting groove or the end surface of the other mating member; one axial end of the reinforcement ring () projects from an outer peripheral portion of a first seal bead (), and the first seal bead () has rigidity lower than rigidity of a second seal bead (); and the second seal bead () is formed with interference relative to the end surface of the other mating member or the end surface of the setting groove in a state that one axial end of the reinforcement ring () contacts the end surface of the setting groove or the end surface of the other mating member.
