Abstract
An air-intake control apparatus of an internal combustion engine formed by attaching a flange portion provided to an end portion of a drive motor to a cylindrical hole portion. A throttle body has at least one positioning projection (or recess) provided to an inner wall of the cylindrical hole portion. The drive motor complementarily has at least one positioning recess (or projection) provided to the flange portion at a position corresponding to the positioning projection (or recess). The drive motor is attached to the cylindrical hole portion while the positioning recess (or projection) abuts on the positioning projection (or recess) in such a manner that a center distance between a motor shaft and a throttle shaft takes a predetermined value. Hence, not only attachment workability but also attachment accuracy of the drive motor can be enhanced. The air-intake control device therefore has higher product reliability.
