    摘要： In an in-wheel motor drive device, a speed reduction part is a parallel shaft gear reducer that includes a plurality of gear shafts extending in parallel to one another. One of the gear shafts is coupled with the rotation shaft of the motor part, the other one of the gear shafts is coupled with the wheel hub of the wheel hub bearing part. Remaining gear shafts decelerate the rotation of the motor part and transmit it to the wheel hub. The motor drive device includes a parking gear attached to any of the gear shafts. The parking pawl has a projection portion engaged with a recess portion of the parking gear. A movement member enables a parking pawl to move between a locking position engaged with the recess portion and an unlocking position not engaged therewith. The parking gear, the parking pawl, and movement member are housed inside a housing.

    摘要： In the link structure linking an in-wheel motor drive device (11) placed in a hollow area of a road wheel (W) of a turnable wheel to a damper (31), a damper bracket (32) extends in the vehicle traverse direction and at least a transversely outer end (321) of the damper (31) is placed in the hollow area of the road wheel (W). A first joint (18) is placed in the hollow area of the road wheel, and rotatably links the transversely outer end (321) of the damper bracket (32) to the in-wheel motor drive device (11). The damper (31) has a lower end (311) coupled to a transversely inner end (322) of the damper bracket (32).

    摘要： An in-wheel motor drive device includes an electric motor section, a speed reducer section having a speed-reduction structure using parallel shaft gears, a wheel bearing section, and a casing. The parallel shaft gears include at least one intermediate shaft each having an input-side and output-side intermediate gears, and an output shaft having a final output gear. The at least one intermediate shaft and the output shaft each have both end portions supported by rolling bearings to be rotatable. Among the rolling bearings, at least one rolling bearing arranged close to the input-side intermediate gear or a rolling bearing arranged close to the final output gear is arranged in a radially-inner-side recess portion of the gear, which is arranged close to the corresponding rolling bearing.
