Abstract
An electronically-controlled throttle valve control device may include a coil spring that is engaged with a throttle body and a rotating body to bias a throttle valve in a fully opening direction and a fully closing direction, a spring guide that is provided to the rotating body and is capable of supporting the coil spring from inside, and an opener member that is provided to the rotating body and is biased by the coil spring in the fully opening direction or the fully closing direction. The coil spring includes a first coiled portion that is capable of biasing the throttle valve in a first direction, a second coiled portion that is capable of biasing the throttle valve in a second direction, and an intermediate coiled portion that is positioned between the first and second coiled portions. The coil spring is formed such that a central axis of the intermediate coiled portion is displaced radially outwardly relative to a central axis of the first coiled portion.
