Title:
MOTOR
Document Type and Number:
Japanese Patent JP2017103947
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor that allows a rotor-side stopper to be easily checked to see whether it securely comes into contact with a stator-side stopper even when the rotor-side stopper for regulating the rotating range of a rotor with respect to a stator and the stator-side stopper are arranged in the motor.SOLUTION: In a motor 1, a stator-side stopper 13a for regulating the rotating range of a rotor with respect to a stator has a shape projecting in a radial direction. An end face of the stopper 13a in a circumferential direction and a rotor-side stopper 9a come into contact with each other, thereby regulating the rotating range of the rotor with respect to the stator. The stoppers 9a, 13a are arranged closer to the center side of the motor 1 than a bearing part 21a is in the axial direction. The bearing part 21a has a notch part 21c, notched such that at least part of the stopper 13a can be seen when the motor 1 is viewed from the one end side in the axial direction.SELECTED DRAWING: Figure 5
