In a left-right wheel driving device (10) including two motors (1, 2) that drive left and right wheels and a gear mechanism (3) that amplifies a torque difference between the two motors (1, 2) and transmits the amplified torques to the left and right wheels, respective, rotating shafts (1A, 2A) of the two motors (1, 2) are coaxially disposed. The left-right wheel driving device (10) further includes motor shafts (11) that are positioned between the rotating shafts (1A, 2A) coaxially with the rotating shafts (1A, 2A) and that are each provided with a motor gear (21), counter shafts (12) that are disposed in parallel to the motor shafts (11) and that are each provided with a first intermediate gear (22) meshing with the motor gear (21) and a second intermediate gear (23) having a diameter smaller than that of the first intermediate gear (22), and output shafts (13) that are disposed in parallel to the motor shafts (11) and that are each provided with an output gear (24) meshing with the second intermediate gear (23). The gear mechanism (3) is disposed on one end side of each of the output shafts (13) and one of the left and right wheels is disposed on the other end side of the output shaft (13).
