Electronically controlled throttle control apparatus

摘要

In a gear case of a throttle body, a valve gear is fixed to one end of a throttle shaft, an intermediate reduction gear is rotatable around an intermediate shaft, a pinion gear is fixed to a motor shaft of a drive motor, and a full close position stopper is provided for defining the full close position of a throttle valve. Those are provided all in alignment with the longitudinal centerline of the gear case. For car models where the throttle body bore inside diameter is identical but the rotation direction of the drive motor differs, only some components in the gear case need be replaced and the other components in the gear case can be used as common components.
