摘要： A fluid pressure nut 16 has a first load supporting member 17 disposed in a flange 13a and a second load supporting member 18 axially movably attached to the first load supporting member 17, wherein the second load supporting member 18 is screw-connected to a bolt 15 in a screw hole 28. A pressure chamber is provided between the first load supporting member 17 and the second load supporting member 18, and a seal ring 44 is attached to an end portion of a pressure chamber 27. The seal ring 44 includes a first curve portion contacting with the first load supporting member 17, a second curve portion contacting with the second load supporting member 18, and a pressure receiving portion continuing into the first and second curve portions, wherein pressure applied to the pressure receiving portion is converted into axial-directional sealing forces of the curve portions.

摘要： A first load-receiving member having a cylinder and a screw hole through which a bolt is thread-engaged and a second load-receiving member having a piston and a fastening face that is made in contact with a member to be fastened are attached to a nut, and a number of balls made of steel the surface of which is lubricated by grease are loaded into a pressure chamber that is formed as a compartment by the cylinder and the piston. Since these balls exert fluidity in the pressure chamber, a load applied to the balls is transmitted to the cylinder and the piston through the balls by screwing the input bolt. Thus, the first load-receiving member is moved in the axis direction with respect to the second load-receiving member, thereby applying a tensile force to the bolt.
