Abstract: An object of the present invention is to provide an anti-loosening device that exhibits its anti-loosening effect by means of an eccentric fit between a protrusion 12 of a nut 10 and a recess 22 in a nut 20, wherein the inclination of the nut 20 relative to the nut 10 when they have been tightened is minimized. The outer peripheral surface of the protrusion 12 and the inner peripheral surface of the recess 22 are constructed in such a manner that, with the nuts screwed to a threaded shaft S and an eccentric fit established between the protrusion 12 of the nut 10 and the recess 22 in the nut 20, the tapered outer peripheral surface portion 12a of the protrusion 12 interferes with the tapered inner peripheral surface portion 22a of the recess 22 along part of the circumference while a gap is formed between the distal-end outer peripheral surface portion 12b of the protrusion 12 and the closer-to-bottom inner peripheral surface portion 22b of the recess 22 along the entire circumference.

Abstract: A novel screw-fastening assembly having anti-loosening capabilities includes a first and a second screw elements 11,12 adapted to be screw-fastened; the element 12 includes a recess R, the recess being open toward the element 11; and the element 11 includes an protrusion P, the protrusion being introduced into the recess R in a fastened state. The recess R has an inner peripheral surface formed in a cylindrical shape that is straight along the axial direction. The protrusion P is shaped as a circular column or cylinder having a maximum-diameter portion at one location along the axial direction. The protrusion P and the recess R are eccentric relative to each other such that the maximum-diameter portion of the protrusion and the inner peripheral surface of the recess are in pressure contact only along part of their circumference in the fastened state.

Abstract: A member with threads is provided that is made of a carbon-fiber-reinforced composite material with improved strength. Carbon fibers each extending in the axial direction across at least two threads appearing in a longitudinal cross section are embedded in the at least two threads in a zigzag manner along the surface shape of the at least two threads appearing in a longitudinal cross section. Preferably, the member is a nut, where the above-described structure is embedded in the threads of the female threadform of the nut, thereby providing a nut that is lightweight and exhibits improved strength.

Abstract: There is provided an implant having a slack prevention function by an eccentric fitting structure. An engaging shaft 53, which is decentered with a screw shaft 52, is provided at the end of an abutment screw 5, and is engaged with an engaging hole 45 provided in the bottom of a screw hole 44, into which an abutment screw 5 is screwed, and thus, the screw shaft 52 is inclined to and eccentric from the screw hole 44. Thereby, the screw shaft 52 comes to be strongly pressed partially in a circumferential direction toward the screw hole 44, so that internal stress in the horizontal direction is accumulated on the screw shaft 52. The screw 5 is threaded with maintaining prevailing torque caused by the internal stress, which enables the screw 5 to be fastened to the right position.

Abstract: A novel pivot-mounting device is provided that can accommodate various thicknesses of rotatable members and facilitate repeated attachment and detachment and that can prevent loosening due to vibration. A lower nut (4) is used to fix a bolt (2) to an object to which a member is to be attached (A), and then an upper nut (3) having a boss (32) that rotatably supports the rotatable member (B) is tightened on the bolt (2). The lower nut (4) includes an engagement recess (41) into which the boss (32) can be fitted; the outer peripheral surface of the boss (32) and the inner peripheral surface of the engagement recess (41) are each formed into a straight cylinder shape; and the outer peripheral surface of the boss (32) is slightly eccentric relative to the female thread hole (3a) such that the boss (32) engages the engagement recess (41) to produce, in both nuts (3, 4), pressing forces in a direction perpendicular to the axis.

The second control unit selects one of the target braking controlled variable and the backup target braking controlled variable in accordance with operating conditions of the first control unit and the second control unit. The second control unit outputs a drive signal to the actuator so as to bring the braking force of road wheel closer to the selected one of the target braking controlled variable and the backup target braking controlled variable.
