A rubber crawler which reduces all conventionally occurring drawbacks by forming rubber, lugs to the outer peripheral surface so as to correspond to protrusion meshing positions that are susceptible to external flaws or cracking, with significantly enhanced durability of the rubber crawler. In a rubber crawler with metal cores provided at front and rear with protrusions for wheel fall-off prevention, in which the metal cores are buried at a fixed pitch along the longitudinal direction of a rubber elastic body and the wheel fall-off prevention protrusions of adjoining metal cores mesh with each other, rubber lugs are formed to the outer peripheral surface so as to correspond to the meshing portions of the wheel fall-off prevention protrusions. 1 - metal core, 2,3 - protrusions, 5a, 5b rubber lugs, 6 - sprocket engagement hole.
