Abstract
A throttle control apparatus has a torsional coil spring that is associated with the throttle body and the rotator to bias throttle valve to a predetermined intermediate angle between a full open angle and a full close angle. An actuator rotates the rotator against a biasing force of the torsional coil spring. The torsional coil spring has a first and a second loading portions that apply biasing forces to the rotator to bias the throttle valve from the full open angle or from the full close angle toward the intermediate angle. The rotator is provided with a spring force receiving portion that receives both the biasing forces applied by the first and second loading portions so that the first and second loading portions sandwich the spring force receiving portion therebetween.
