Abstract
In an engine intake control apparatus, a cover is made of synthetic resin, a motor support plate is made of metal, a positioning boss is integrally formed on the cover, a first positioning hole arranged on a motor support plate is fitted on an outer peripheral surface of the positioning boss, and the positioning boss is positioned and fitted with a throttle valve body each other. With such an engine intake control apparatus, it is possible to perform with high accuracy the mutual positioning between the three components, i.e. the motor support plate, the cover and the throttle valve body, and it is possible to effectively improve the opening and closing accuracy for the opening and closing of the throttle valve by the motor.
