PROBLEM TO BE SOLVED: To significantly improve the rubber crawler life by positioning outside periphery side end portion of flat plane of cross-directional end portion of a rubber crawler whose core metal has cambered portion toward inside periphery of the cross-directional portions, further outside with respect to the outside periphery side face. SOLUTION: Each cross-directional end of a core metal 2 of rubber crawler is inverted to inside periphery side by approximately 30 deg. to form a cambered portion 5. The cambered portion 5 is covered with a padded portion 6 that is formed in connection with the inside periphery end portion of a rubber elastic body 1 in longitudinal direction. In the cross-directional end portion of the rubber elastic body 1, particularly, an end portion 8 of a flat plane 7 in vertical direction is positioned further outside (P2) with respect to a level state P1 on outside periphery side face of the core metal 2. In this structure, rubber thickness is made large by parting crack concentrating portion in cross- directional end portion of the rubber elastic body from cross-directional end of the core metal. This prevents cracks from occurring in this portion.
