PROBLEM TO BE SOLVED: To enhance versatility by applying a bracket to various kinds of motor-driven wheelchairs different in the size of wheels without redesigning a constitutive part, by arranging the part installing bracket in the vicinity of a driving wheel, and installing a driving motor and a motive power transmission mechanism on the bracket. SOLUTION: A wheel shaft 11 is fixed to a rear frame 24 of a frame for arranging a seat of a motor-driven wheelchair, and driving force of a driving motor 8 is transmitted by a motive power transmission mechanism to a driving wheel unit 5 installed on the wheel shaft 11. A part installing bracket 12 is arranged in the vicinity of the driving wheel unit 5, and the driving motor 8 and the motive power transmission mechanism are installed on the bracket 12. Thus, when installing the bracket in the motor-driven wheelchair, there is no need to care about the dimensional size of a hub main body and the cover body, so that the bracket can be applied even to various kinds of motor- driven wheelchairs different in the size of wheels without redesigning a dimension and the arranging relationship of a constititive part.
