PURPOSE: An exhaust gas recirculation system of a vehicle is provided to minimize reduction difference of NOx of each cylinder, and to reduce vibration and noise from uniform combustion by evenly mixing exhaust gas and fresh air with a mixing unit in the connection portion between an intake passage and an EGR(Exhaust Gas Recirculation) pipe and supplying exhaust gas without deviation. CONSTITUTION: An exhaust gas recirculation system including an EGR pipe branched off from an exhaust system of an engine of a vehicle and an intake system communicated with the EGR to mix and supply air and exhaust gas to a combustion chamber is composed of a housing(20) communicated with the outlet of the EGR pipe and composed of a hollow flow passage(21), a flow pipe(22) communicated with the intake passage of the intake system and spaced from the hollow flow passage in the housing, and communication holes(23) arranged around the flow pipe to communicate the hollow flow passage of the housing with the flow pipe of the intake system.
