PURPOSE:To make it possible to move a vehicle on a wall surface without scratching the wall surface, by utilizing tires packed therein with magnetic fluid for travelling wheels. CONSTITUTION:Magnetic fluid 24 is packed in a tire 22, and electromagnets 30 are provided on both side parts of the tire 22. In order to move a wall surface running vehicle, at first the coils of the magnets 30 are energizged to creat magnetic flux for attraction between a wall surface 14 and the magnetic fluid 24 and between the lower end of an iron core 36 and the wall surface 14 so that the vehicle 10 is attracted onto the inclined wall surface 14. Then, wheels 20 are rotated by drive motors 39 to advance the vehicle 10. Further, the turning of the vehicle may be easily made by a steering device. With this arrangement utilizing magnetism, the vehicle 10 is surely attracted onto the wall surface 14, and as well the tread area of each wheel of the vehicle with respect to the wall surface 14 is small, thereby the steering of the vehicle is simple so that the vehicle may be smoothly turned. |
