Abstract: A turning mechanism is equipped with a wire (first movable member) which moves in a movable direction (direction of the arrow B) under the motive power of a turning actuator, a wire (second movable member) which moves in a movable direction under the motive power of a turning actuator, and a coupler connecting the two wires. The coupler is configured in a manner so that the wires are capable of being moved independently in the case that a difference (differential angle) between the toe angles of the rear wheels lies within an allowable range, whereas in the case that the differential angle has exceeded the allowable range, is configured in a manner so that the wires are capable of being operated in a mutually interlocked manner.

Abstract: An actuating member includes: a first movement member and a second movement member which are located at a proximal side of the elongated member and are configured to be relatively movable toward and away from each other along an axial direction of the elongated member; a push-pull member that includes a first connection portion configured to be connected to the first movement member, a first extension portion extending from the first connection portion toward a distal side in the axial direction of the elongated member, a second connection portion configured to be connected to the second movement member, and a second extension portion extending from the second connection portion toward the distal side in the axial direction of the elongated member; and an operation member configured to operate the movement of the first movement member and the second movement member.

Abstract: A linear actuator includes: a pinion shaft coaxially coupled to a motor shaft; a driven gear that is engaged with a pinion gear on the pinion shaft; a nut that rotates with the driven gear; a feed screw mechanism that converts rotation movement of the nut into linear movement of a rod; a coupling part allowing an outer peripheral surface of the motor shaft to be serration coupled to an inner peripheral surface of a vertical hole in the pinion shaft; and a pressurizing unit that generates a pressure that axially acts between e motor shaft and the pinion shaft in the coupling part.

Abstract: An electric power steering apparatus comprises a transmission mechanism having a drive gear and a driven gear. One end of the drive gear is supported by a bearing hole in a housing through a bearing and a curved plate spring. The curved plate spring comprises a main body surrounding the bearing and at least one crank-shaped elastic tongue supported by at least one of ends of the main body. A recess formed on an inner peripheral surface of the bearing hole has a bottom and a pair of inner wall surfaces opposed to each other in the circumferential direction of the bearing hole. A relief portion for avoiding contact with a connection portion of the elastic tongue is formed between at least one of the inner wall surfaces and the inner peripheral surface of the bearing hole. A boundary between the relief portion and the inner peripheral surface of the bearing hole is engaged with the main body of the curved plate spring, to restrict the movement of the main body in the circumferential direction.
