PURPOSE:To eliminate the necessity to make a hydraulic pump large-sized by providing a through oil path provided from the first gear side toward a planetary gear and a receiver member guiding the lubricating oil flowing from the engagement point between the first gear and the second gear to the direction parallel with a shaft center to the above through oil path. CONSTITUTION:The lubricating oil accumulated at the lower section in the fourth chamber reaches the third gear 82 and the second gear 80 the lubricating oil stuck to the outer periphery teeth of the gear 80 is conveyed to the engage ment portion with the first gear 78 and flows out from here. The pressure of the lubricating oil is increased at the outer periphery of the gear 78 by this pump action, part of the lubricating oil flows out to the direction parallel with the shaft center of the gear 78 and passes a bearing 130 and is received by a cylindrical receiver member 204, and it is guided by the member 204 and reaches the flange section 66 of a carrier 70 and fed to the inner periphery of the sun gear 56 side of planetary gears 60 and 62 via a through oil path 202 from there. No lubricating oil is required to be fed by pressure to lubricate the gears 60 and 62. |
