Abstract
A rubber crawler has a structure in which connecting members are sequentially fitted onto wing portions adjacent to each other without using steel cords for resisting tensile force applied to the rubber crawler. Accordingly, the rubber crawler of the present invention has excellent characteristics in that breakage of steel cords due to the tensile force can be prevented, and torsion of the rubber crawler can be reduced.
