To provide a vehicular motor driving apparatus that can reduce wasteful heat of an electric motor and rotate the electric motor even when travelling resistance torque exceeds generated torque of the electric motor.

The vehicular motor driving apparatus can reduce the wasteful heat of the electric motor 22 by actuating a clutch function of a torque limitter device 56, interrupting a power transmission passage between the electric motor 22 and a rear wheel 26, and idling the electric motor 22, when a drive torque Tm of the electric motor 22 reaches a torque limitter value Tlim of the torque limitter device 56, and moreover, can collect energy by converging the idled electric motor 22 into rotation energy of a flywheel 68 and accumulating it.
