PURPOSE: To improve responsiveness and changeover accuracy at controlling changeover of an EGR valve.

CONSTITUTION: This EGR device is provided with a first flow control valve 14 of a first EGR passage (r1) of a diesel engine 12, a second flow control valve 15 of a second EGR passage (r2), a lever opening sensor 16 outputting a lever opening signal θL, an engine rotation sensor 17 outputting an engine speed Ne signal, and first and second valve opening sensors 18, 19 outputting valve opening quantity signals of the first and second flow control valves 14, 15. Further it is provided with a control means 20 which computes a valve opening quantity (h0) corresponding to a target recirculating quantity Q0 of the first and second flow control valves based on the lever opening θL signal and the engine speed Ne signal and controls the first and second flow control valves to be the valve opening quantity, the control means 20 computes the deviation dA between the valve opening quantities (h1), (h2) and the valve opening quantity (h0), it controls simultaneously both flow control valves while the deviation is over the set deviation width -a≤dA≤a, and controls only either of both flow control valves while the deviation dA is within the set deviation width.
