Rear wheel steering device for e.g. automobile, has movable element fixed on part and movable in axial direction of screw when screw is screwed in nut, where surface of element receives charges which are subjected to pulling and flexion

摘要

The device has a fixing part (20) at a level of a case (12) to fix the case on a chassis (1) by fixing a socket (2) at a level of the chassis with a screw (30) and a nut (40). A pair of opposed parts (21, 22) is provided at a level of the fixing part facing each other in an axial direction of the screw to maintain the socket. A movable element (23) in a form of a ring is fixed on one of the parts (21, 22) and is movable in the axial direction of the screw when the screw is screwed in the nut. A lateral surface of the element receives the charges which are subjected to pulling and flexion.
