To reduce the weight of the drive system as a whole with a central focus placed on an inverter, particularly, the length of a wiring and a tubing around the inverter and also to reduce the weight of an electric vehicle through an efficient cooling of the inverter, a single inverter (5) used to supply an alternating current power to all in-wheel motor devices (4) is positioned at a bilateral position positioned between the left and right in-wheel motor devices (4). A radiator (7) for cooling the inverter (5) is positioned forwardly of the inverter (5). The inverter (5) is disposed above a battery (6) or the inverter (5) and the battery (6) are disposed forwardly and rearwardly relative to each other.
