PROBLEM TO BE SOLVED: To provide a motor-driven vehicle, which can be stably traveled over a step or ladder and can perform compact turns. SOLUTION: A traveling unit 7 is configured by arranging a driving wheel unit 32 composed of an arm 12, sprockets 21, 22 and 23 pivotally supported on the arm 12 and a pair of front and rear wheels 10 and 11 on each of left and right sides of a driving case 6 and the traveling unit 7 is located on each of front and rear sides of a vehicle stand 2. In such a motor-driven vehicle 1, the torque ratios of operation upon the sprockets 21, 22 and 23 are made almost equal and the driving wheel units 32 can be individually driven.
