Description of the Related Art Hitherto, in order to travel on a snowy road, a chain is attached to a tire and wheels are replaced with spiked tires to prevent slipping and allow safe operation and traveling. However, they are often unpleasant to attach and detach because they stain clothes and the like, and it takes a lot of time and labor. Further, even if slip is prevented, the chain and spiked tires become inoperable on frozen slopes, which is not sufficient to avoid danger. Therefore, various types of vehicles with a caterpillar have been provided so far in order to surely climb and descend a snow slope.

走行に移行される。Further, when approaching the snowy road and shifting to running on the caterpillar C, the front belt wheel 2 is lowered to the grounding position, and the lower belt guide roller 5 follows the front belt wheel 2 together. Down to the ground. When the vehicle body B is further moved horizontally to the same vehicle body width as the rear wheel R of the automobile, the endless belt 3 is attached to the front belt wheel 2 and the upper and lower belt guide rollers 4,5. When the rear wheel R is rotated at this time, the rear wheel R is then pulled in from the side portion of the tire T of the wheel R from the end portion of the endless belt 3, and the endless belt 3 is completely wheeled on the tire T. When the endless belt 3 is attached to the tire T, the endless belt 3 is pulled by the rotational driving of the rear wheel R and rotates together with the front belt wheel 2. That is, from tire T running to ratchet C

However, according to the present invention, the rear wheel tires T to the end of the wheels can be driven during running. It is possible to automatically switch from the endless belt 3 to the rear wheel tire T, and from the endless belt 3 to the road without snow, from the road without snow to the road without snow, to the road with snow. And now you can move without any effort. For this reason, switching between running on snowy roads and running on snowless roads will occur immediately, dust will be generated by chains and spiked tires, and slip accidents will occur after traveling from running on snowless roads to running on snowy roads. Will be able to be reduced.
