Abstract
In the intake air quantity control device for an internal combustion engine, in which an open area formed at a portion of the throttle body is encapsulated by a cover including a rotational angle detector, a throttle gear is fixed to a throttle shaft for rotatably supporting a throttle valve and has a fitting portion at a portion of the throttle gear. The rotational angle detector includes a rotor that is rotatably supported and arranged in the cover in such a way that an axis of the rotor is identical to an axis of the throttle gear, and a lever that is provided at a portion of the rotor, which is faced to the throttle shaft, and engaged to a wall portion of the throttle gear at a portion of the lever.
