Abstract
In a planetary gear set, a pinion shaft extending through one of planetary pinions has one and opposite end portions supported by two spaced plate portions of a carrier. Needle bearings are disposed between the pinion and the pinion shaft. Pinion washers extend around the piston shaft and radially between the pinions and the adjacent plate portions of the carrier. In order to withstand a thrust which the needle bearings are subjected to, the pinion washers have integral portions extending axially into spaces defined between the pinion, the needle bearings and the spaced plate portions of the carrier. Alternatively, the pinion shaft may have integral portions extending radially into the spaces.
