ント。[Claims for Utility Model Registration] (1) A rotating side seal member and a stationary side seal member are arranged facing each other in contact with each other in a casing, and the stationary side seal member is pressed toward the rotating side seal member by a biasing mechanism. A rotary joint in which a predetermined surface pressure is applied to a rotating side seal member and a stationary side seal member, characterized in that a surface pressure adjustment mechanism for changing the pressing force of the biasing mechanism is provided. Joint. (2) A casing, a rotating member whose rear end is inserted into the casing and rotatably supported, a rotating seal member fixed to the rear end of the rotating member, and a rear end surface of the rotating seal member. a stationary side seal member that comes into contact with the stationary side seal member, a sleeve that supports the stationary side seal member and is movable in the axial direction of the casing, and a sleeve that is arranged at a predetermined distance from the sleeve and moves in the axial direction of the casing. a spring that is disposed between the piston member and the sleeve and biases the sleeve toward the rotating member; a moving mechanism that moves the piston member in the axial direction of the casing; a fluid passage formed in the axial direction of the casing by communicating the rotating seal member, the stationary seal member, the sleeve, and the piston member; and a fluid supply port that opens in the casing and communicates with the rear end surface of the piston member. A rotary joint characterized by being equipped with.
