検出機構。[Claims for Utility Model Registration] (1) A vehicle steering system comprising a steering rod that moves in the axial direction to steer wheels, and a steering angle sensor that determines the steering angle of the wheels from the distance traveled by the steering rod. The apparatus further comprises: a displacement converting means for converting the moving distance of the steering rod by a certain ratio smaller than 1 determined according to a maximum moving distance of the steering rod, and the steering angle sensor A steering angle detection mechanism for a vehicle steering device, comprising a displacement sensor that detects a displacement converted by. (2) The displacement converting means has an inclined surface that extends along the axial direction and has an inclination corresponding to the ratio that moves together with the steering rod, and the displacement sensor has an inclined surface that extends along the axial direction and has an inclination that corresponds to the ratio. Claim 1 of the Utility Model Registration Claim, comprising a differential transformer including a sensor shaft that is always in contact with the inclined surface in the right angle direction and moves in the right angle direction in response to the movement of the inclined surface. A steering angle detection mechanism of a vehicle steering device according to. (3) The wheel is a rear wheel, and the slope and inclination of the first steering rod that steers the rear wheel are determined according to the maximum travel distance of the second steering rod that steers the front wheel. A steering angle detection mechanism for a vehicle steering device according to claim 2, wherein the steering angle detection mechanism is different from the slope of a similar inclined surface of a steering rod.
