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.

A cowl box is provided in a vehicle body between a rear edge of an engine hood and a windshield. The front hood is mounted on the vehicle body to be swung open and closed about a hinge mounted on the vehicle body on the rear side of the rear edge of the front hood. The cowl cover is opened and closed by a driving mechanism comprising a four-bar link mechanism including first and second links each of which is pivoted at one end thereof on a member mounted on the front hood and at the other end on the lower surface of the cowl cover and which extend substantially in parallel spaced from each other in the longitudinal direction of the vehicle body, a driving motor and a connecting mechanism for transmitting the output power of the driving motor to the four-bar link mechanism.

A controlling circuit for a motorcar front window wiper accommodating apparatus of a concealed type wherein a wiper is accommodated within an opening portion provided between the front window lower edge and the bonnet rear-end edge, the opening portion is opened and closed by the cowl cover, to a controlling circuit for interlockingly controlling the operation between the cowl cover and the wiper. It is adapted to operatively cooperate the opening and closing operations of the cowl cover with the wiper, to actuate the wiper when the cowl cover reaches the position where it does not interfere with the lifting wiper wiping portion to be lifted in the position before it reaches its fully open position in the opening process of the cowl cover so as to retain the speediness of the wiper actuation to remove the delay feeling for improving the safety.
