Abstract
A carrier structure for a planetary gear system has a pinion shaft rotatably supporting a pinion gear, a carrier body fixedly supporting the pinion shaft, needles disposed between an internal periphery of the pinion gear and an external periphery of the pinion shaft, a pinon washer disposed between each end face of the pinion gear and the carrier body and mounted on the pinion shaft for supporting thrust load of the pinion gear, and a support portion provided in the pinion washer for supporting the thrust load of the needles. The pinion washer has sliding surfaces mating with the pinion gear and the carrier body, to respectively. At least one of the sliding surfaces is provided with a plain bearing member. When the pinion gear is rotated, the thrust of the needles can be born by the support portion of the pinon washer. Also, when the pinion gear is rotated, the portion to slid about the support portion is the end face of the needle, the external peripheral surface of the pinion shaft and the internal peripheral surface of the pinion gear.
