ABSTRACT:
An intake air control apparatus uses a male screw portion of an intermediate opening adjustment screw retractively screwed in a female screw hole of a sleeve nut fixedly held between fitting bosses. The intermediate opening degree adjustment screw can be thus held on a gear housing. Stress otherwise generated by forcing the male screw directly into a resin portion is prevented around or in the neighborhood of the female screw hole, i.e. the fitting bosses. The intermediary of the sleeve nut also increases the area of the resin portion receiving the shock load, thereby improving shock resistance.
