A control device of an exhaust gas recirculating device capable of preventing a flow detection sensor inside an intake passage from being affected by the operation of an exhaust gas recirculating valve provided in an exhaust gas recirculating system, wherein drive pulses of a frequency to reciprocate a valve disc (11) of the exhaust gas recirculating valve at a frequency not disturbing a vortex produced in a Karman air flow sensor disposed inside the intake passage are supplied to each phase coil of a stepping motor (1) driving the exhaust gas recirculating valve, preferably the frequency of the drive pulses should be 10 Hz or less and varied.
