A wheel driving device is proposed in which it is possible to prevent vibration of an internal gear due to torque transmitted to the internal gear from being transmitted to a speed reducer casing. The wheel driving device includes a speed reducer (20) for transmitting the rotation of an electric motor (10) to a hub ring (51) supporting a vehicle wheel after reducing its speed. The speed reducer is a cycloid speed reducer including an external gear (24), and an internal gear (26) meshing with the external gear (24) and rotationally fixed to the speed reducer casing (21) through a rotationally fixing means (40) which is also capable of elastically supporting the internal gear (26). The rotationally fixing means (40) absorbs, by elastic deformation, vibration of the internal gear (26) due to torque transmitted from the external gear (24) to the internal gear (26), thereby preventing the vibration of the internal gear from being transmitted to the speed reducer casing (21).
