とするエンジンのアイドル回転数制御装置。 An idle operation detection means for detecting an idle operation, a rotation speed detection means for detecting an engine rotation speed, a control amount adjusting means for adjusting a control amount related to the engine rotation speed, and the above-mentioned idle operation detection means and rotation speed detection means. Feedback control means receives the output of the engine and performs feedback control of the engine speed using the control amount adjusting means during idling operation; deceleration control means for controlling the control amount adjusting means so that the engine speed is lowered when the engine speed exceeds the speed limit, and deceleration control limiting means for limiting the deceleration control when the engine speed does not decrease during deceleration control by the deceleration control means. An engine idle speed control device comprising:
