Patent abstract
To improve the lifespan of a rubber crawler by reducing as much as possible cracks due to bending at the time of wraparound. Bending deformation no longer becomes concentrated at a specific place because bending rigidities at the time of wraparound are not so different from each other overall. For that reason, the occurrence of cracks can be reduced. As a result, the lifespan of the rubber crawler is improved.
