An internal combustion engine equipped with an idle control valve whose opening is controlled so that the actual engine speed approaches a preset target speed during idling operation, in a bypass passage that communicates upstream and downstream of the throttle valve in the intake passage. In the idle speed control device, means for detecting a steady state during idle operation, and means for comparing engine speed in the steady state during idle operation with an allowable rotation speed for a cooling water temperature set higher than a target rotation speed. 1. An idle speed control device for an internal combustion engine, comprising means for stopping fuel supply when the engine speed exceeds an allowable speed.
