The invention provides a drive unit which can realize a plurality of forward modes without complicating the structure. The torque converter amplifies the torque in the first rotational direction. The first torque transmission path (6a) transmits torque via a torque converter (3). The second torque transmission path (6b) does not transmit torque via the torque converter (3). The first gear train (41) outputs torque in the first rotational direction as torque in the forward rotational direction. The second gear train (42) outputs the torque in the first rotational direction as the torque in the reverse rotational direction. The control unit (9) controls the motor (2) so as to rotate in a first rotational direction in a first forward mode and outputs torque via the first torque transmission path (6a) and the first gear train (41), and controls the motor (2) so as to rotate in a second rotational direction in a second forward mode and outputs torque via the second gear train (41). And outputs torque via the second torque transmission path (6b) and the second gear train (42).
