Claims

[Claims for Utility Model Registration] A motor having a case supported by a support body;
The planetary gear includes a drum rotatably supported by a motor case at one end via a bearing, and a planetary gear reduction mechanism provided in the drum to reduce the rotational output of the motor and transmit it to the drum. In a winch in which the reduction mechanism rotatably holds a plurality of pinions around a predetermined sun gear by a fixed carrier fixed to a case of a motor, the fixed carrier holds a plurality of predetermined pinions fixed to the case. a plurality of struts extending in the axial direction of the drum between the pinions, and a connecting section connecting the plurality of struts on the other end side of the drum from a predetermined plurality of pinions, the connecting section and the drum. A winch characterized in that a bearing is interposed between the inner peripheral part of the other end and the other end.
