星歯車機構。[Claims for Utility Model Registration] A plurality of pinion gears meshing with at least one of a ring gear and a sun gear are rotatably fitted around the outer periphery of each pinion pin, and both ends of each pinion pin are supported by a carrier. In the planetary gear mechanism, the carrier includes a carrier body that supports one end of the pinion pin and a carrier cover that supports the other end of the pinion pin, and the carrier body and the carrier cover and a bridge portion extending parallel to the pinion pin between each pinion gear and divided into a bifurcated portion into an inner layer portion having a small diameter and an outer layer portion having a large diameter on the tip side; A planetary gear mechanism characterized in that a tip end of the bridge portion is fixed to the other of a carrier body and a carrier cover.
