A rear wheel drive device (1) is provided with first and second electric motors (2A, 2B), a rear wheel (Wr) for propelling a vehicle (3), and a one-way clutch (50) provided in the motive power transmission route of the first and second electric motors (2A, 2B) and the rear wheel (Wr). The one-way clutch (50) is provided with: an inner race (51) and an outer race (52) having the same rotational axis, the inner race (51) and outer race (52) being capable of rotating relative to each other; and a sprag (53) interposed between the inner race (51) and the outer race (52). The rear wheel drive device (1) is provided with an eccentricity acquisition means for acquiring eccentricity, which is the misalignment between the rotational axis (O') of the inner race (51) and the rotational axis (O) of the outer race (52). |
