(Effects of the Invention) As described above, the present invention provides a crawler traveling device in which an endless belt-shaped crawler is hung around a driving wheel, an idler wheel, and a series of intermediate idlers and rotates in circulation. The feature is that an endless belt made of an elastic material such as rubber is hung between the rolling wheels, and the intermediate free rolling wheels are brought into contact with the crawler via the endless belt, so that the cushioning effect is improved. In the case of metal crawlers and elastic crawlers whose transfer surface is on the core metal, it is possible to reduce noise and improve the durability of the crawler. It is possible to increase speed, the running of the vehicle is not hindered even if the endless belt is damaged, and the damaged endless belt can be easily replaced with a new one. In addition, when the present invention is applied to an elastic crawler, there is no damage to the rubber or other materials on the rolling surface of the intermediate idler wheels of the crawler body made of an elastic material such as rubber, so the thickness of the rubber etc. can be reduced, making the elastic crawler lightweight. It is possible to achieve this goal.

Furthermore, since the endless belt engages with the links of the metal crawler or the guide protrusions of the elastic crawler, it is possible to prevent the wheels from coming off, and safe and quiet circulation is possible.
