PROBLEM TO BE SOLVED: To a wheel driving mechanism in a compact manner in the internal space of a wheel itself by fixing a wheel drive mechanism such as a motor, a reducer, a brake and a power transmission gear for driving a wheel to an axle suspending a magnetic body by use of a surplus space. SOLUTION: An axle 3 is fixed in the rotation constraint state to the body element 11 of a wall surface moving device by a key and a key and a key way, and an axle flange 1 is disposed rotatably in a body with the wheel side plate 2 around the axle 3. In the internal space of the axle, a driving part fitting bracket 6 is fixed to the waxle 3 in a surplus space produced outside the movable range of the magnetic body 4. A series of wheel driving mechanisms such as a running drive reducer 7a, a light-weighted and small-sized running drive electric motor 7b with high power density, and power transmission gears 8, 9 are disposed in a suitable combination on the bracket 6 to construct an attractive wheel for magnetic body running incorporating the running drive mechanism. Even if the magnetic body 4 is rotated in the direction of exhibiting the maximum magnetic force in a difference in level, it will not interfer with the running drive mechanism fixed to the axle 3. |
