Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent sudden change of an engine speed by properly controlling the quantity of sucked air. SOLUTION: The device comprises a feedback control means 17, a sucked air quantity control means 18, a reset means 19, and a prohibition means 20. The feedback control means 17 is for controlling the quantity of sucked air at the idling operation of the engine so that the engine speed is the same as a target frequency of idling rotation. The sucked air quantity control means 18 is for controlling the quantity of sucked air so that the sucked air is gradually increased when the operation condition of the engine is changed from the idling operation to the non-idling operation. The reset means 19 is for resetting the quantity of feedback control calculated by the feedback control means 17 to zero. The prohibition means 20 is for substantially prohibiting the rest means 19 from resetting the quantity of feedback control while the operation condition is changed from the idling operation to the non-idling operation till the gradual increase of the quantity of sucked air controlled by the sucked air quantity control means 18 is finished.
