DRIVE DEVICE FOR TRANSPORTATION MACHINE

A rear wheel driving system (1) includes a first and second motors (2A, 2B), rear wheels (Wr) which propel a wheeled vehicle (3), and a one-way clutch (50) which is provided on a power transmission path between the first and second motors (2A, 2B) and the rear wheels (Wr). The one-way clutch (50) includes inner race (51) and an outer race (52), which has the same rotational axis and rotates relatively, and sprags (53) which are interposed between the inner race (51) and the outer race (52). The rear wheel driving system (1) includes an eccentric acquiring unit for acquiring an eccentricity which is a deviation between a rotational axis (O') of the inner race 51 and a rotational axis (O) of the outer race (52).
