摘要： A first planetary gear and a clutch are placed between a second carrier of a second planetary gear and an output shaft in the axial direction. A transmission case has a small diameter tubular portion that rotatably supports an output shaft, an annular wall portion extended radially outward from the small diameter tubular portion, and a large diameter tubular portion extended in the axial direction from the outer periphery of the annular wall portion such that the first planetary gear and the clutch are partially surrounded. A mount is fixed to a vehicle body of a vehicle so as to at least partially overlap the small diameter tubular portion, the annular wall portion, and the large diameter tubular portion as viewed in the radial direction. A parking gear of a parking lock device is coupled to the outer periphery of the second carrier.

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