An exhaust gas recirculation apparatus is provided to precisely mix exhaust gas with new fuel mixture when the exhaust gas exhausted from cylinders of an engine is re-circulated through an intake system so as to reduce NOX. An exhaust gas recirculation apparatus(1) of a vehicle includes an introducing opening(3) to receive exhaust gas and to communicate with an exhaust gas introducing pipe(2), partitions(5) having a plurality of through-holes(4) and provided at inner sides of the introducing opening to form a mixing chamber(6) of a predetermined space, and a gas pipe(7) for allowing new fuel mixture to flow, and a guide pipe(8) for guiding fuel mixture mixed in the mixing chamber into a combustion chamber, respectively coupled with the inner ends of the mixing chamber. The respective through-holes of the partitions are coupled with mixing pipes(10) having a plurality of penetrating holes(9) so that new fuel mixture flows into the guide pipe through the mixing pipes. The exhaust gas introduced into the mixing chamber when the new fuel mixture passes through the mixing chamber enters the mixing chamber and is mixed with the new fuel mixture.
