ABSTRACT:
A lubricating oil feeding device includes a carrier and a carrier cover that are attached to both ends of the pinion shaft of the planetary gear and that are arranged in an axial direction of an input shaft of the automatic transmission; an oil sump groove that opens in a peripheral direction and the axial direction of the input shaft, the oil sump groove is structured by a wall portion of the carrier cover formed radiating from a center of the input shaft, a base portion of the carrier cover that extends in an axial direction of the pinion shaft, and an end portion on an inner peripheral surface of a clutch hub that is connected with the base portion; and an oil passage that feeds lubricating oil from the oil sump groove to the pinion shaft, and provides the lubricating oil for the planetary gear.
