項記載の減速体内蔵小形電動機。[Claims for Utility Model Registration] (1) A stator winding wound in a ring shape is fixed to the inner peripheral side of a cylindrical part of a stator yoke that also serves as a motor cover, and the stator yoke cylindrical part is connected to the stator winding. The fixed shaft is extended axially outward from the line to form stator magnetic poles, and is connected to the reducer case at the outer periphery of this extension, and is fixedly held cantilevered on the wall of the reducer case. The outer circumferential surface of a rotatably supported permanent magnet rotor faces the inner circumferential surface of the stator magnetic poles via a gap, and a gear is cut on the outer circumference of the small shaft diameter portion of the rotor. In a small electric motor with a built-in speed reducer whose rotation is reduced by a plurality of sets of gear trains in the speed reducer case and taken out to the outside via a final output shaft, the free end of the cantilevered fixed shaft is formed of an elastic material. A small electric motor with a built-in speed reducer, characterized in that the motor is supported by a bearing, and the outer periphery of the bearing is held by the surface of a hollow hole formed in the center of the end face of the stator yoke. (2) The bearing provided to support the free end of the fixed shaft is a bearing having an oil retaining material containing a lubricant attached to the end face facing the rotor. Scope of claim for utility model registration No. 1
A small electric motor with a built-in speed reducer as described in .
