A planetary gear device includes a bearing inner cylinder including an internal gear on the inner circumferential side, a bearing fitted on the outer circumference of the bearing inner cylinder, an output shaft outer cylinder fitted on the outer circumference of the bearing, and an output shaft end plate that fixedly supports the planetary carrier and transmits a rotation thereof to the output shaft outer cylinder. A wheel is fitted onto the outer circumference of the output shaft outer cylinder so as to prevent relative rotation. The bearing inner cylinder is fixed to a support frame. A drive motor is fixed coaxially with the planetary gear device on the side of the support frame opposite to the bearing inner cylinder, and a rotation shaft is coupled to the sun gear.
