Abstract

A drive device includes a fluid coupling and a rotary electrical machine. The fluid coupling includes an impeller and a turbine, and is configured such that a torque is inputted thereto from one axial side and outputted therefrom to another axial side. The rotary electrical machine includes a first stator and a rotor. The first stator is disposed in a non-rotatable manner. The rotor is disposed to be rotated about a rotational axis of the fluid coupling. The first stator includes a first stator core, first and second coil ends. The first coil end protrudes from the first stator core in an axial direction. The second coil end protrudes from the first stator core to an opposite side of the first coil end in the axial direction. The first coil end is bent radially outward and located in part radially outside an outer peripheral surface of the first stator core.
