Abstract

PURPOSE:To prevent the occurrence of deficiency in cooling of a portion around a pinion during high speed rotation by arranging an oil guide member for directing the flow of oil injected from a shaft located at the central part of a carrier to a pinion, on the carrier. CONSTITUTION:Since, during high speed rotation, the force of oil injected through an oil injection shaft 4 located to the central part of a carrier 1 is increased, oil is difficult to flow to an engaging part 21 of a pinion 2. However, since an oil guide member 5 directing the direction of the flow of oil to the pinion 2 and bent at a central part is arranged to a carrier, oil flows to the engaging part 21 of the pinion 2, and the pinion 2 is always cooled by means of oil. The oil guide member 5 axially intercouples a base plate 11 and a carrier plate 12 in a part where the base plate 11 and the carrier plate 12 are positioned in parallel to each other, resulting in improvement of return rigidity of the carrier 1.
