PURPOSE: A vehicle-wheel driving device for an in-wheel system is provided to enhance assembling performance and productivity by modularizing each part of an in-wheel system. CONSTITUTION: A vehicle-wheel driving device for an in-wheel system comprises an output shaft(132), an in-wheel motor(120), a reduction gear unit, a reducer housing, and a motor housing. The output shaft drives wheels. The in-wheel motor is arranged in the wheel to rotate an input shaft, which is indirectly connected to the output shaft. The reduction gear unit is connected between the input shaft and the output shaft. The reduction gear unit reduces and transfers the number of rotation of the input shaft to the output shaft. The reducer housing comprises a front housing and a rear housing, which protect the reduction gear unit. The motor housing protects at least a part of the in-wheel motor.
