Abstract
A vehicle drive apparatus includes a fluid coupling connected to an engine, and a rotating electric machine connected to the engine via the fluid coupling. The fluid coupling has an impeller to which torque having been output from the engine is input, and a turbine facing the impeller. The impeller rotates about a rotation axis. Torque having been output from the impeller is input to the turbine via a fluid. The turbine rotates about the rotation axis. The vehicle drive apparatus has a path provided between an output shaft of the engine and the impeller, the path through which torque having been output from the engine is transmitted to the impeller not via the turbine, and paths through which torque having been input to the impeller is output via the rotating electric machine, passing through a radially outside relative to the impeller with respect to the rotation axis from the impeller via the turbine.
