<p>A planetary gear device includes a bearing member (60) mounted on an inner coupling annular wall surface (3531) of a planet carrier (30) to support rotatably a force transmitting member (50) relative to the planet carrier (30) in an accommodating chamber of a mounting frame (10) . A sun wheel member (51) of the force transmitting member (50) meshes with a plurality of planet wheel members (40) which mesh in turn with an inner annular toothed portion (11) of the mounting frame (10) so as to reduce speed of an output shaft of a motor that is coupled with a tubular coupling portion (522) of the force transmitting member (50). With such an arrangement, accurate alignment of the sun wheel member (51) with the planet carrier (30) can be maintained. <IMAGE></p> |
