When supporting a wheel (30), which has arranged therein a motor (40) comprising a stator (41) and a rotor (42), and which is provided with an anchoring side member (60) for supporting the stator (41) and a rotating side member (31) to which rotation of the rotor (42) is transmitted, in between a pair of arms (20L, 20R) with a wheel axle (21), an engaging section (22p) that is to be engaged to the anchoring side member (60), and that positions the rotating center of the rotating side member (31) in relation to the anchoring side member (60), is formed on an axle (22) that supports the rotor (42) and the rotating side member (31) rotatably, and the axle (22) is positioned in relation to the anchoring side member (60) by making the engaging section (22p) engaged to the anchoring side member (60) and making the rotating side member (31) and the anchoring side member (60) become a unit, which in turn aligns the centers of insertion holes thereof into which the wheel axle (21) is to be inserted, thereby making the mounting of the unit (U) (which is the wheel (30)) in between the pair of arms (20L, 20R) easier. |
