A mixing device structure for recirculation exhaust gas in an automobile is provided to improve degree of freedom of control and precision of an engine control by maintaining concentration of recirculation exhaust gas constant. A mixing device structure for recirculation exhaust gas in an automobile comprises an inlet pipe through which new gas to be sent to a combustion is introduced; an EGR path connecting an EGR valve or an EGR cooler to the inlet pipe; an EGR tube(30) located on the spot where in the newly introduced gas and the recirculation gas meets; and an EGR pipe(50), installed to the EGR tube inclined, through which recirculation exhaust gas is introduced. The recirculation gas is guided to a suction pipe(10) through the EGR path. The EGR tube regularly maintains the concentration of the recirculation exhaust gas.
