PURPOSE: An angle of a nozzle portion of variable nozzle turbine turbocharger is varied without a vacuum pump, a pulse width modulation valve, and an actuator to reduce cost and volume. CONSTITUTION: A control device of variable nozzle turbine turbocharger comprises an engine rpm sensor(10) for sensing engine rpm, a fuel injection sensor(30) for sensing an injection amount of a fuel valve, a stepping motor(50) for driving a nozzle portion of outer turbocharger system, and a controlling portion(20) outputting driving voltage value of the stepping motor by the engine rpm and the fuel injection amount from a predetermined control map.
