An exhaust gas recirculation valve in a vehicle has two valves that are controlled individually by using one driving source. The exhaust gas recirculation valve enables secure operation of a vehicle even if the driving source is out of order. The exhaust gas recirculation EGR valve includes a driving unit having a driving motor for rotating a motor shaft and an interlocking unit for receiving rotational force from the motor shaft. A rod portion moves upon reception of the rotational force. A valve unit at an end portion of the rod portion controls a flow rate of the exhaust gas. A valve housing is coupled to the driving unit as one unit and has an EGR port and a bypass port. The interlocking unit includes a valve return member for rotating the motor shaft forcibly to make the valve unit to move to an initial position.
