In a drive device, it is possible to reduce the size of a planetary gear mechanism, reduce the size and weight of the entire drive device, reduce the dimension between the tip ends of an output shaft for outputting rotational torque, the tip ends protruding in directions opposite to each other, and improve vehicle stability. External sun gears are coupled to an input shaft. Planetary carriers are coaxial with the input shaft, are adjacent to planetary gears in the axial direction thereof, and have external gears that rotate together with the planetary carriers. Ring gears respectively meshing with the planetary carriers are rotatably supported and rotate in mutually opposite directions by means of a differential mechanism. Intermediate gears and input-side gears are respectively fixed to intermediate shafts, the intermediate gears respectively meshing with the external gears. Output gears respectively meshing with the input-side gears are respectively fixed to output shafts.
