Abstract

A wheel is provided with a motor having a stator and a rotor and has with a fixed-side member supporting the stator and a rotative-side member receiving rotation transmitted from the rotor. The wheel is supported between a pair of arms with a wheel axle. An axle rotatively supports the rotor and the rotative-side member. An engaging part is provided for engagement with the fixed-side member to position the center of rotation of the rotative-side member with respect to the fixed-side member. The fixed-side member and the rotative-side member are integrated by engagement of the engaging part with the fixed-side member. This configuration allows the axle to be positioned with respect to the fixed-side member, such that the centers of holes in the axle and the fixed-side member for insertion of the wheel axle will be in alignment. The unit U is then incorporated in between the pair of arms.
