Exhaust gas aftertreatment device for an internal combustion engine of a motor vehicle

The invention relates to an exhaust gas aftertreatment device for an internal combustion engine of a motor vehicle with at least one exhaust gas conduction element (10), which comprises at least one exhaust gas channel (12) through which exhaust gas of the internal combustion engine can flow, with a dosing device (16), by means of which, at at least one supply point (18), a reducing agent for denitrifying the exhaust gas can be introduced into the exhaust gas channel (12), and with a first flow dividing element (28), which is arranged in the exhaust gas channel (12) and by means of which the exhaust gas channel (12) is divided into a first tributary channel (30), through which a first tributary flow of the exhaust gas can flow, and a second tributary channel (32), through which a second tributary flow of the exhaust gas can flow and in which the supply point (18) is arranged, wherein the first flow dividing element (28) comprises a channel region (38), through which the second tributary flow can flow and whic
