|1. (WO2017179670) WHEEL MODULE|
|Applicants:||MINEBEA MITSUMI INC.
A wheel module (1, 1A-1G, 1200, 2200, and 3200) according to an embodiment is equipped with a wheel, a motor, a holding member, and a brake. The wheel (64, 1212) has a tire attached thereto. The motor (65, 64D-65H, 1213i, 2213i, and 3213i) is arranged on the inside of the wheel, and is equipped with a stator and a rotor. A shaft (61, 61A-61H, 1213c, 2213c, and 3213c) is affixed to the rotor so as to be coaxial with the rotational axis of the rotor, and transmits the rotational force of the rotor to the wheel. The holding member (1, 1A-1G, 1213e, and 3213e) holds the stator. The brake (100, 100A-100H, and 1230) restricts the rotation of the shaft. One end of the holding member in the axial direction of the rotational axis of the rotor is affixed to and supported by a support member (5, 1220). The brake is arranged on the opposite side from the wheel, with the support member therebetween. The shaft passes through the one end of the retaining member and a through-hole formed in the support member, and extends to the interior of the brake.
