PURPOSE:To permit the compulsory lubrication between a pinion gear and a pinion shaft and between the pinion gear and a shaft supporting part by forming an oil passage in the pinion shaft and an oil reservoir onto the pinion carrier of a planetary gear apparatus, thus permitting lubricating-oil to be compulsorily supplied. CONSTITUTION:A transmission is equipped with a planetary gear apparatus consisting of a sun gear 1 integrally formed with a sun gear shaft 29 rotatably fitted onto an output shaft 12, pinion gear 2 meshed with the sun gear 1, carrier 4 which supports the pinion gear 2 and has a shaft supporting part 4B spline- fitted onto the outer periphery of the output shaft 12, and a ring gear 3. In this case, an oil passage 4E is formed on the shaft 4A of the carrier 4, and an oil reservoir 4H is formed at one edge of the oil passage 4E, thus constituting an oil storage means 6. Lubricating oil is supplied between the pinion gear, shaft 4A, and the supporting part 4B through the oil storage means 6 from a lubricating- oil feeding means 5. |
