Abstract
A drive device includes a fluid coupling, a transmission shaft, and a rotary electrical machine. The fluid coupling includes a cover, a turbine, and an impeller. The turbine is fixed to the cover. The impeller is disposed inside an outer shell formed by the cover and the turbine. The impeller is opposed to the turbine. The transmission shaft extends to penetrate the outer shell of the fluid coupling. The transmission shaft is connected to the impeller. The rotary electrical machine includes a first stator and a rotor. The first stator is disposed in a non-rotatable manner. The rotor is attached to the outer shell of the fluid coupling.
