A left and right wheels drive system includes: a first drive source (M1) and a second drive source (M2); a left drive wheel (WL) and a right drive wheel (WR); and a gear mechanism (2) interposed between the first and second drive sources (M1,M2) and the left and right drive wheels (WL,WR), the gear mechanism including: a pinion set (20) in which a plurality of pinion gears (21,22) are installed on one shaft; and an element group (E1,E2,E3,E4,E5) which is linked with the pinion set (20) and which includes a first element (E3,E5), a second element (E4), a third element (E1) and a fourth element (E2). When the first element (E3,E5) is held stationary, the second, third and fourth elements (E4,E1,E2) rotate in the same direction. When the first element (E3,E5) is held stationary, the second element (E4) rotates at a higher speed than the third and fourth elements (E1,E2). One of the first and second drive sources (M1,M2) is connected to the first element (E3,E5), and the other of the first and second drive sources (M2,M1) is connected to the second element (E4). One of the left and right drive wheels (WL,WR) is connected to the third element (E1), and the other of the left and right drive wheels (WR,WL) is connected to the fourth element (E2).
