vehicle. A driving apparatus of an electric vehicle includes an electric motor provided in anelectric motor case, the electric motor having an output shaft protruding outside theelectric motor case, a planetary gear mechanism provided in a speed reducer case, theplanetary gear mechanism transferring the driving force at a reduced speed from theoutput shaft to the driving wheel. The output shaft integrally includes a sun gear meshedwith a planetary gear of the planetary gear mechanism. The speed reducer case includesa positioning section disposed concentrically with the output shaft, the positioningsection being combined with the electric motor case. A meshing length between the sungear and the planetary gear is larger than an insertion depth of the positioning section.
