ABSTRACT:
A throttle valve control device for an internal combustion engine controls an opening degree of a throttle valve by electrically drivingly rotating a rotary shaft, to which fixed is the throttle valve, in response to an angular movement of a speed acceleration pedal. The control device is actuated only in case of emergency. The control device is provided with a throttle valve returning mechanism for imparting a torque to cause the rotary shaft to rotate in a direction in which the throttle valve is fully closed. '
