摘要： When a fourth sun gear 24s is held stationary so as to be unrotatable, a Ravigneaux type planetary gear mechanism 25 transfers power, which has been transferred from an input shaft 20i to a third carrier 23c, to a third sun gear 23s and a third ring gear 23r with the speed of the power increased such that the rotational speed of the third sun gear 23s is higher than the rotational speed of the third ring gear 23r. A clutch C2, which corresponds to the third sun gear 23s which rotates at a higher speed than that of the third ring gear 23r, is disposed between the Ravigneaux type planetary gear mechanism 25 and a second planetary gear 22 disposed in proximity to the Ravigneaux type planetary gear mechanism 25 with respect to a first planetary gear 21.

摘要： When a third sun gear 23s and a fourth sun gear 24s are non-rotatably held stationary by a brake B2, a compound planetary gear train 25 of an automatic transmission 20 increases the speed of the power transmitted to a third carrier 23c, and transmits the resultant power to a third ring gear 23r and a fourth carrier 24c serving as a first output element and to a fourth ring gear 24r serving as a second output element. A clutch C3 for selectively connecting the fourth ring gear 24r of the compound planetary gear train 25 to first and second sun gears 21s and 22s of first and second planetary gears 21 and 22 and a clutch C4 for selectively connecting the third ring gear 23r and the fourth carrier 24c of the compound planetary gear train 25 to the first and the second sun gears 21s and 22s are disposed on a side closer in the axial direction to the compound planetary gear train 25 than the first and the second planetary gears 21 and 22.

摘要： An automatic transmission (11) includes a bicylindrical member (50) in which an inner cylinder portion (50a) and an outer cylinder portion (50c) are integratedly formed through a flange portion (50b), and which forms a portion of a clutch drum of a third clutch (C3). The inner cylinder portion (50a) structures a first base portion in which a piston (43) of a fourth clutch (C4) slides, and the outer cylinder portion (50c) structures a second base portion in which a piston (33) of the third clutch (C3) slides. An end portion (50d) of the outer cylinder portion (50c) is provided extending so as to run through a clutch drum (42) of the fourth clutch (C4), and the clutch drum (42) is restricted from detaching by a snap ring (51). The clutch drum (42) also contacts and supports a cancel plate (34), and is supported by the outer cylinder portion (50c). The clutch drum (42) is thus supported more toward an outer perimeter side, and even if the clutch drum (42) is subject to a centrifugal hydraulic pressure of a cancel oil chamber (37), deformation can be suppressed.
