There is provided an electrically driven working vehicle that needs reduced assisting power from an electrical storage device when accelerating subsequent to modulation and still obtains acceleration at least equivalent to that of torque converter vehicles. The electrically driven working vehicle has an engine 1, a generator motor 5 connected mechanically to the engine 1, a generator inverter 6 for controlling the amount of power generated by the generator motor 5, a traveling motor 7 for driving a vehicle body, an electrical storage device 3 connected electrically to the generator inverter 6 and to the traveling motor 7, and a forward/reverse switching device 103 for switching the traveling direction of the vehicle body. The vehicle includes a control device 100 for outputting to the generator inverter 6 an instruction to increase the amount of power generated by the generator motor 5 when the voltage of the electrical storage device 3 is equal to or lower than a maximum voltage level and a speed signal of the traveling motor 7 given upon switching of the forward/reverse switching device 103 is equal to or lower than a predetermined speed.
