Provided is a driving device for rear wheels of a 4 wheel driving electric vehicle, which can minimize a loss in the drive power during 4-wheel by transmitting the drive power to the rear wheels based on a disconnector input shaft, rather than a clutch, after synchronizing a rotating speed of the disconnector input shaft based on a first motor with a rotating speed of a hub based on rear wheels. Other aspects of the present invention provide a driving device for rear wheels of a 4 wheel driving electric vehicle, which can prevent a loss in the drive power during 2-wheel driving by preventing a load based on a differential device from being generated by connecting the differential device between a reduction gear group and the disconnector input shaft.
