ABSTRACT:
A motor-driven throttle valve control device has a throttle shaft and a coupling lever rotatably provided on the shaft, both being coupled by a spring. A default spring energizes the coupling lever toward a position of the default opening of the throttle valve. The throttle shaft rotates separately from the coupling lever in the direction of the full open throttle valve from a point at which the coupling lever comes into contact with a stopper defining the default position and, together with the coupling lever, in the full close direction of the throttle valve from the point. Thereby, the throttle valve can be kept at the default position by the default spring through the coupling lever when a motor driving the throttle valve is not powered.
