An internal gear configuring a reduction gear is supported and fixed to a rotation side flange provided on an axially outer end portion of a hub, and the hub is rotationally driven based on a driving force input through the internal gear. Accordingly, since a drive shaft for rotationally driving the hub is not necessarily connected to a center hole of the hub, an electric generator and a wireless communication device can be disposed in an accommodating space having a large space provided on an axially inner side of the hub.
