<P>PROBLEM TO BE SOLVED: To provide a rubber crawler of a simple constitution provided with a derailment inhibiting protrusion having an enhanced derailment inhibiting performance, by suppressing the amount of a shift in the turning direction of a core when the rubber crawler runs on an obstacle in the width direction. Ž<P>SOLUTION: The rubber crawler is constituted by embedding a core 12 having a pair of guide protrusions 16a and 16b approximately in its center part with its wing portions 14 extending in the width direction and embedding steel cords 20 provided on the grounding face side of the wing portions 14 and extending in a circumference direction. Derailment inhibiting protrusions 30a and 30b formed in parallel with the grounding face and protruding in directions opposite to each other are provided on the grounding face side of the wing portions 14 of the core 12. On the ground face side of the derailment inhibiting protrusions 30a and 30b, bulged portions 31a and 31b bulged to the grounding side are formed, and are sandwiched between the steel cords 20 from both sides in the width direction.
