Abstract
A throttle control device includes a motor coupled to the throttle shaft, so that the throttle valve rotates to open and close an intake air channel as the motor is driven. A detection device serves to detect the degree of opening of the throttle valve and includes a pair of magnets and a sensor. The magnets are mounted to the throttle shaft via a magnet support and are positioned to oppose each other across the rotational axis of the throttle shaft in order to produce a uniform magnetic field. The sensor is mounted to the throttle body and serves to detect a direction of the magnetic field produced by the magnets, so that the detection device outputs a signal representing the degree of opening of the throttle valve.
