    摘要: In an automatic transmission, a planetary gear set 30 is disposed adjacently to an end cover 6b and configured such that its inner peripheral face of a carrier 33 is rotatably supported on an outer peripheral face of a boss portion 6b1 provided at the end cover 6b. A lubricating-oil supply passage comprises an oil passage \ 6br formed from the end cover 6b to the boss portion 6b1, an oil passage 33r formed in the carrier 33 so as to tightly connect to the oil passage 6br at the inner face of the carrier, and an oil passage 35r formed in the pinion shaft 35 so as to tightly connect to the oil passage 33r and reach an outer peripheral face of the pinion shaft. There is provided a lubricating oil supply means V for supplying lubricating oil to the bearing portion 101 via the above-descried lubricating-oil supply passage.

    摘要: On an input shaft 1 are provided in order from a side of an engine E a torque converter 4 with a lock-up clutch, a first planetary gear set G1 as a multiplying mechanism, a counter drive gear 5 outputting a rotational drive force to a countershaft 2 , a second planetary gear set G2 as a speed-change element, a third planetary gear set G3 as a speed-change element. Accordingly, there can be provided an automatic transmission for six forward speeds with plural planetary gear sets, clutches and brakes that can properly reduce a clutch capacity and restrain gear noises with its compact and light-weighted structure.
