Claims

[Scope of Claim for Utility Model Registration] (1) In a steering device that electrically detects the steering state of a steering wheel, drives an actuator based on this detection signal, and steers a steering wheel by the actuator, a steering wheel; a steering shaft connected to the steering shaft; a steering shaft force detector that detects the axial force of the steering shaft; a reaction force generator that generates a steering reaction force based on a detection signal output by the steering shaft force detection means; A deformable annular gear having a substantially elliptical cross section disposed within the gear is pressed by a cam member and partially meshes with the internal gear, the annular gear is connected to the steering shaft, and the cam member is connected to the reaction force generator. A steering device comprising: a speed reduction mechanism that is coupled to the internal gear and connects the reaction force generator to the steering shaft at a speed reduction ratio according to the difference in the number of teeth between the internal gear and the annular gear. (2) The input shaft connected to the steering handle and the output shaft connected to the reaction force generator are rotatably supported coaxially in the housing, and the input shaft and output shaft are rotated relative to each other via a torsion bar. possible to connect,
A steering device in which a torque sensor for detecting relative rotational displacement between an input shaft and an output shaft is arranged in a housing, the first fixing means for prohibiting axial displacement of the input shaft; and the torque sensor and the reaction force. a second shaft provided between the generator and the output shaft for inhibiting axial displacement of the output shaft;
A steering device comprising: a fixing means; and a steering device.
