検出センサ。[Claims for Utility Model Registration] A drive shaft connected to a rotational drive source is rotatably supported by a pair of bearings, and a detection disc for detecting the rotational speed of the drive shaft is provided on the outer periphery of the drive shaft. In the fixed rotation detection sensor, a coil spring is disposed inside the drive shaft, and the stopper plate whose outer peripheral portion is pressed against the one bearing portion by the biasing force of the coil spring is driven by the drive shaft. The detection disk is arranged to be slidable in the axial direction of the shaft, and the detection disk is pressed against the other bearing by the pressing force of the stopper plate, thereby applying a constant braking torque to the drive shaft. Characteristic rotation detection sensor.
