PROBLEM TO BE SOLVED: To provide an electric wheel driving device of small size and lightweight, easy to show a sufficient traveling performance, and generating a low noise during operation, at a low cost. SOLUTION: An electric motor 5 and a wedge roller friction roller type reduction gear 6 are combined as one body and arranged on the inner diameter side of a wheel 1 constructing a wheel 3. The purpose is achieved by using the wedge roller friction roller type reduction gear 6 having a good transmitting efficiency and generating the low noise during operation.
