Abstract
A planetary gear has a sun gear having external teeth on an outer peripheral side, a plurality of pinion gears engaged with the sun gear, a carrier supporting the plurality of pinion gears, a circular oil catch plate on an end of the carrier, and a rotation member having a ring gear, on an outer peripheral side of the carrier and the oil catch plate. An engaging element engaged with the rotation member is disposed on an outer periphery of the planetary gear. The oil catch plate includes an open close valve which opens a passage at at least a predetermined rotation number. Lubrication oil supplied to the planetary gear is guided to the engaging element through the passage when the open/close valve is opened. This enables adjusting of the lubrication amount in accordance with a variation occurring in a ratio of a lubrication amount to each part.
