PURPOSE: To detect deviation in steering angle accurately through a simple structure, by generating electromotive force when an input shaft rotates according to the steering of a steering wheel, and detecting the rotational displacement of the input shaft.
CONSTITUTION: This rotation detector consists of a rotor magnet 13 provided at one terminal of a control valve 3, a stator coil 17, and a casing which contains said members and serves as an iron core yoke, and the rotor magnet 13 is fixed to the input shaft 11 of the control valve 3 in such a way that it rotates together with the shaft in one body. Therefore, the rotation detector has a kind of generator structure for generating electromotive force by the rotation of the input shaft 11 of the control valve 3. Thus, the input shaft is provided as part of the rotation detector and its rotation is detected directly, so the deviation in steering angle is detected very accurately through the simple structure.
