Abstract

A planetary gear mechanism includes a planetary carrier and pinions rotatably carried on the planetary carrier through pinion shafts. An annular lubricating oil supply member is mounted on a ring gear supporting member which supports a ring gear on its outer periphery and which is rotatable. The lubricating oil supply member has a plurality of fins formed radially thereon. The lubricating oil received within the lubricating oil supply member while submerged in the lubricating oil is scattered by a centrifugal force and supplied to oil reservoirs defined in the adjacent side of the planetary carrier and then from the oil reservoirs via oil passages in the pinion shafts to the needle bearing which supports the pinions. With the above construction, it is possible to effectively supply the lubricating oil to the pinion shafts of the planetary gear mechanism when the planetary is in a fixed position.
