装置のフエイルセーフ装置。 In an idle rotation speed control device, an idle control valve driven by a step motor is interposed in a bypass passage that bypasses an intake throttle valve provided in an intake passage of an internal combustion engine. The present invention further comprises: a cutoff means for cutting off the step motor while ensuring a predetermined flow rate; a means for determining a failure of the step motor; and a control means for operating the cutoff means based on a failure determination signal from the failure determination means. A fail-safe device for the idle speed control device.
