モータ。[Scope of Claim for Utility Model Registration] A shaft, a rotating member rotatably attached to the shaft via a bearing member, a stator attached to the shaft, and a rotor magnet disposed on the rotating member. and a circuit assembly including a Hall element for detecting the rotational angular position of the rotor magnet, wherein the shaft is provided with a movement preventing protrusion that protrudes radially outward. , the stator and the circuit assembly are mounted on the shaft so as to be movable in the axial direction thereof without relative rotation, and the stator and the circuit assembly are elastically biased toward the movement preventing protrusion. A motor characterized in that elastic means is provided, and the stator and the circuit assembly are held at a predetermined position in the axial direction of the shaft by the action of the movement prevention protrusion and the elastic means.
