Abstract
An in-wheel drive unit basically has a motor, a motor casing member, a planetary gear set, a hub flange and a pair of bearings. The motor includes a rotor that is rotatably driven. The motor casing member covers the motor. The planetary gear set is arranged coaxially about the rotational axis of the rotor. The planetary gear set includes a sun gear coupled to the rotor, a ring gear supported on the motor casing member, at least one pinion gear operatively arranged between the sun gear and the ring gear, and a carrier supporting the pinion gear. The hub flange is fixedly coupled to the carrier. The bearings rotatably support the hub flange and the pinion gear. The bearings are disposed on opposite sides of the pinion gear with respect to an axial direction of the pinion gear.
