Abstract
A driving apparatus for an electric vehicle includes (a) an electric motor including a rotary shaft and a rotor that is rotatably supported by the rotary shaft, (b) a speed reducer configured to reduce a speed of rotation of the rotary shaft of the electric motor and to output the rotation of the rotary shaft, and (c) a housing that houses the electric motor and the speed reducer. The housing is partitioned by a partition wall into an electric motor room in which the electric motor is housed and a speed reducer room in which the speed reducer is housed. A first refrigerant used in the electric motor room and a second refrigerant used in the speed reducer room are different from each other. At least a part of the speed reducer room is received in the electric motor room in an axial direction of the rotary shaft.
