Abstract: 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).
