A wheel module according to an embodiment includes a wheel, a motor, a shaft, a holding member and a brake. A tire is mounted on the wheel. The motor is arranged on the inner side of the wheel and includes a stator and a rotor. The shaft is fixed to the rotor coaxially with a rotation axis of the rotor and transmits rotation force of the rotor to the wheel. The holding member holds the stator. The brake 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. The brake is 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 and the supporting member.
