PROBLEM TO BE SOLVED: To significantly reduce a phenomenon such as derailing by solving the problem that sediment or the like easily intrudes to the inner circumferential surface of a rubber crawler, resulting in derailing or the like, and making intrusion of sediment difficult. SOLUTION: This rubber crawler is a core metal-less rubber crawler comprising an endless rubber elastic body 1, a steel code 2 buried in the rubber elastic body, rubber projections 4 formed on the inner circumferential surface, and rubber lugs 3 formed on the outer circumferential surface, which is laid around a sprocket and an idler provided on a machine body and a track roller arranged between the both. The rubber projections are formed at a fixed pitch synchronously with the sprocket teeth, and a recessed part 5 to be fitted to the sprocket teeth is formed at the apex of each rubber projection.
