PURPOSE: To efficiently feed lubricating oil to the pinion shaft of planetary gear mechanism.
CONSTITUTION: Planetary gear mechanism P is provided with a fixed planetary carrier 6, and a pinion 11i is rotatably supported to the planetary carrier 6 through a pinion shaft 10i. An annular lubricating oil feeding member 22 provided at a ring gear supporting member 13 rotated while supporting a ring gear 12 on the periphery is provided with a plurarity of fins 221 formed radially. Lubricating oil held inside the lubricating oil feeding member 22 is scattered by centrifugal force so as to be fed to an oil reservoir 19 formed at the side face of the planetary carrier 6 and therefrom fed to a needle bearing 16 for supporting the pinion 11i, through the oil passages 101 102 of the pinion shaft 101.
