行なうことができる。 The transport vehicle configured as described above has the towing rod 27 connected to the tow vehicle, and is towed by the travel of the tow vehicle. During this run, due to the turning of the towing vehicle,
Fork 5 of front wheel device 2 whose transport vehicle is also a caster
While rotating around the central axis 8, the rear wheel device 3
turns without rotating, but in this case the wheels 21
Since a plurality of wheels 21 are arranged in the axial direction on the axle 13 so as to be able to rotate independently through the hub 17, when turning, the wheels 21 on the outside rotate at a higher rotational speed than the wheels 21 on the inside. Therefore, compared to the conventional system in which a plurality of wheels on the same axle rotate at the same rotation speed, it is possible to turn easily with a smaller turning radius.
