Abstract
An actuator for an engine idling control mechanism, which includes a throttle valve disposed in an intake manifold tube, a slidable plunger unit, a drive mechanism for forcibly sliding the plunger unit, a detecting device for detecting whether the throttle valve is open or closed, and a control unit for controlling the drive mechanism in relation to the detecting device, for properly setting the degree of opening of the throttle valve at the time the engine is idling. The plunger unit is designed in such a way that, when the throttle valve is closed, the plunger unit is pushed by a control lever which is positioned in accordance with the degree of opening of the throttle valve. The drive mechanism can set the degree of opening of the throttle valve through the plunger unit and the control lever. The detecting device includes a pair of magnets and a detector for detecting the magnetic flux of the magnets. The magnets are slidable in the same direction as the plunger unit, and are slid by the plunger unit when the throttle valve is closed, for adjusting the degree of opening of the throttle valve.
