<p>A first planetary gear unit PR and a clutch C 3 for outputting reduced speed rotation are located on one axial side of a second planetary gear unit PU, and a clutch C 1 for connecting and disconnecting an input shaft 2 to/from a sun gear S 2 and a clutch C 2 for connecting and disconnecting the input shaft 2 input to/from a carrier CR 2 are located on the other axial side of the second planetary gear unit PU. An output mechanism is located between the first and second planetary gear units. As compared with a drivetrain wherein the clutch C 1 or clutch C 2 is located between the two planetary gear units, the two planetary gear units can be located closer together, and a transmitting member that transmits the reduced speed rotation can be made shorter. Further, compared to a drivetrain wherein the clutches C 1 , C 2 , C 3 are located together on one axial side, the oil supply to the hydraulic servos can be simplified.</p> |
