Abstract
A planetary gear device includes a bearing member mounted on an inner coupling annular wall surface of a planet carrier to support rotatably a force transmitting member relative to the planet carrier in an accommodating chamber of a mounting frame. A sun wheel member of the force transmitting member meshes with a plurality of planet wheel members which mesh in turn with an inner annular toothed portion of the mounting frame so as to reduce speed of an output shaft of a motor that is coupled with a tubular coupling portion of the force transmitting member. With such an arrangement, accurate alignment of the sun wheel member with the planet carrier can be maintained.
