Abstract

PURPOSE:To decrease the diameter of a bearing and its friction loss and form the whole device in a small size and in light weight, by externally fitting to a guide shaft the hollow shaft of a planet carrier in a planet gear reduction machine and the pipe-shaped shaft part of a pinion gear in a one-way clutch. CONSTITUTION:A motor 1 rotates its armature 2 about a shaft 3 serving as the center, and the torque is transmitted to a pinion 4 constituting a sun gear of planetary gears B'. And a reduction starter, forming the shaft part of a planet carrier 9 to a hollow shape and inserting a guide shaft 10, stops sliding of both the carrier 9 and the shaft 10 in a thrust direction by engaging a stop ring 12 to be mounted with a pair of ring-shaped grooves 11a, 11b. While the shaft part of the planet carrier 9 is supported through a bearing 14 to a center bracket 13 fixed to the motor 1. Further a pinion gear 20 constituting a part of the one-way clutch C' is slidably fitted to the guide shaft 10 through a bearing 21. In this way, the bearing 14, easily supporting the planet carrier 9, can be constituted in a small diameter.
