A hub arranged at a center of a wheel includes a hub shaft extending along a central axis, a hub body rotatably arranged on the hub shaft, a stator having a coil, a rotor having a rotor shaft extending along the central axis, and a lead wire electrically connected to a conductive wire. The rotor shaft is connected to the hub body. The hub shaft has a through hole penetrating from an end part on the axial other side to the outer peripheral surface. The through hole has a first opening part formed on an outer peripheral surface of the hub shaft. The lead wire is arranged in the through hole. An end part on an axial one side of the first opening part and an end part on an axial other side of the first opening part have different circumferential positions with respect to the central axis.
