Description of the Related Art Conventionally, there are various types in which crawler belts are directly wound around wheels and sprockets not covered with tires, as is well known, but these cannot run with the crawler belt removed. Moving to a place where wheels are reduced, such as a wetland, snowy surface, sandy ground, etc. (herein referred to as a wetland etc. site) must be performed using another road-movable vehicle, which is inconvenient. If there is no choice but to drive on a wetland or other site with a vehicle equipped with tires that can be moved on the road, it is necessary to select a place where reduction does not occur There have been many demands for simple, easy and effective measures to avoid such unavoidable situations.
