PROBLEM TO BE SOLVED: To provide a connection having a simple structure which can connect two wheels interlockably regardless of the mounting angles of two shafts 1, 2 and which can improve traveling stability by controlling a difference in rotation between the two wheels instead of a universal joint which connects the axles of two wheels.SOLUTION: Annular bodies 3, 4 are connected to the ends of the two shafts 1, 2 respectively, and annular-body members 5, 6 are engaged with the annular bodies 3, 4 in a state where each of them forms a chain. Then shafts 7, 8 are projected from the end of each of the annular-body members 5, 6 so that they are opposed to each other, and cylindrical bodies 9, 10 are attached to the shafts 7, 8 respectively. The cylindrical bodies 9, 10 are provided so that they can be rotated by a fixed shaft 20, and a ring-shaped magnet 21 is engaged with the fixed shaft 20 in the hollow space formed by the cylindrical bodies 9, 10. One disc-shaped member 22 is brought into intimate contact with the ring-shaped magnet 21. By the magnetic force of the ring-shaped magnet 21, the rotation of the two shafts 1, 2 can be controlled. |
