PROBLEM TO BE SOLVED: To simplify a mounting structure of an oil catch plate to a carrier of a composite planetary gear mechanism while suppressing oil leakage to the external from between the carrier and the oil catch plate.SOLUTION: In a lubrication device of a composite planetary gear mechanism in which an oil catch plate for collecting an oil scattered by centrifugal force, and introducing the same to an oil passage formed on a pinion shaft of a second planetary gear mechanism, mounted on a carrier of the second planetary gear mechanism, a cylindrical portion connected to an outer peripheral portion of the carrier of the second planetary gear mechanism at its inner peripheral portion, is formed integrally with a ring gear of a first planetary gear mechanism; a step portion for axially positioning the carrier of the second planetary gear mechanism, is formed on the cylindrical portion; a mounting portion of an outer periphery of the oil catch plate is held by the step portion and a side face portion of the carrier of the second planetary gear mechanism; and the carrier of the second planetary gear mechanism is fixed to the cylindrical portion. |
