Abstract

See full text

A first clutch is configured to switch between connection and disconnection of a second carrier and a housing. The first clutch is arranged between a first planetary gear mechanism and a second planetary gear mechanism in the axial direction. A second clutch is arranged between the second planetary gear mechanism and the first planetary gear mechanism in the axial direction. The second clutch has an outer diameter which is smaller than an outer diameter of the first clutch. A first piston is configured so that, by applying pressure to the first clutch, the first clutch is connected. A return spring lines up with the first clutch in the axial direction and is arranged on the outside of the second clutch in the radial direction. The return spring presses the first piston to separate from the first clutch.
