。 An actuator that regulates the closed position of a throttle valve disposed in a carburetor of an internal combustion engine, and an actuator that is attached to the actuator and forcibly operates the actuator in a direction that reduces the opening degree of the throttle valve in the closed position. It has an emergency actuator drive mechanism, a control system that controls the actuator by detecting idle rotation speed, load condition, etc., and an abnormality detection means that detects an abnormality in the actuator and/or the control system. A safety device for idle rotation speed control, characterized in that the abnormality detection means operates the emergency actuator drive mechanism based on the abnormality detected by the abnormality detection means, and controls the throttle valve so that the closed position opening degree is small. .
