A wheel module (1, 1A to 1G, 1200, 2200, 3200) in an embodiment includes a wheel, a motor, a holding member, and a brake. A tire is mounted on the wheel (64, 1212). The motor (65, 65D to 65H, 1213i, 2213i, 3213i) is arranged on the inner side of the wheel and includes a stator and a rotor. A shaft (61, 61A to 61H, 1213c, 2213c, 3213c) is fixed to the rotor coaxially with a rotation axis of the rotor and transmits rotation force of the rotor to the wheel. A holding member (1, 1A to 1G, 1213e, 3213e) holds the stator. The brake (100, 100A to 100H, 1230) restricts rotation of the shaft. One end portion of the holding member in the axial direction of the rotation axis of the rotor is fixed to and supported by a support member (5, 1220). The brake is arranged on the opposite side to the wheel with the support member interposed therebetween. The shaft extends to an inner portion of the brake while passing through through-holes formed in the one end portion of the holding member and the support member.
