ル回転数制御装置。[Scope of Claim for Utility Model Registration] Feedback is provided so that the engine speed reaches the target idle speed by controlling the ignition timing within a control range between a preset upper limit and lower limit during idling. An engine idle speed control device comprising: a working state detecting means for detecting a working state of an external load on the engine; and a predetermined period of time from the time when the operating state detecting means detects the operation of the external load. An engine idle speed control device comprising: upper limit value correction means for correcting the upper limit value to be smaller;
