PROBLEM TO BE SOLVED: To avoid the concentration of distortion by using high hardness rubber relative to the bend of an ear of a rubber crawler, and to thereby suppress the generation of ear cutting. SOLUTION: In the rubber crawler, a steel cord row 2 is buried in a rubber elastic body 1 constituting the rubber crawler. The rubber crawler comprises a rubber projection 3 formed on an inner peripheral side and a lug 4 formed on an outer peripheral side. The high hardness rubber layer 7 exists the an inner surface of the rubber crawler corresponding to left and right ends of a member contacted with the inner peripheral surface of the rubber crawler.
