MINIATURE MOTOR

摘要

[PROBLEMS] A miniature motor in which the diameter and the size are reduced by preventing a failure that the bearing comes off the motor housing fitting part due to the force exerted in a thrust direction on the bearing through a drop impact, or the like, and thereby decreasing the number of components without marring the output characteristics of the miniature motor. [MEANS FOR SOLVING PROBLEMS] In the miniature motor, the magnet containing portion of the small-diameter section of the motor housing is partially provided with a step perpendicular to the rotary shaft, and the step has a magnet stop surface for holding the magnet at a noncontact position with respect to the bearing when the magnet abuts against the magnet stop surface in the thrust direction of the rotary shaft.
