PROBLEM TO BE SOLVED: To provide a drive unit assembly capable of reducing exhaust emissions and the weight, and exhibiting enhanced gear reduction in a wider range. SOLUTION: An electric drive device is provided for each of driven wheels so that the exhaust is reduced, and a planetary axle assembly is dispensed with so that the weight is reduced. Further, in order to achieve enhanced gear reduction in a wider range, an inner planet gear has a different number of teeth in a reduction gear assembly than an outer planet gear to achieve the desired gear reduction.
