回転数制御装置。[Scope of Claim for Utility Model Registration] An intake increasing means for increasing the amount of intake air after the engine is started; an idle speed adjusting means for adjusting the idle speed of the engine; a speed sensor for detecting the actual speed of the engine; Feedback control means for controlling the idle rotation speed adjusting means in a feedback manner so that the actual rotation speed detected by the rotation speed sensor converges to the target idle rotation speed; When the actual rotation speed returns to the set rotation speed or higher after starting the control by the feedback control means when the rotation speed has decreased below the set rotation speed, if the feedback control amount at that time exceeds the set value, the feedback control is performed. control stopping means for holding the feedback control amount and stopping control of the feedback control means by resetting the feedback control amount if the feedback control amount does not exceed a set value. Rotation speed control device.
