A rubber crawler comprising:
- an endless rubber body entrained around a plurality of wheels;
- a plurality of rubber projections that are formed at the rubber body at intervals around a peripheral direction of the rubber body, that project toward an inner peripheral side of the rubber body, and that limit movement of the wheels in a rubber body width direction through contact;
- and
- at least one metal member embedded in each rubber projection, the at least one metal member raising a rigidity of the rubber projection in the rubber body width direction, and including a portion that is exposed from the rubber projection;
- wherein,
- in each rubber projection, the at least one metal member extends from an apex face side to a base side of the rubber projection, with one end portion in an extension direction of the at least one metal member exposed from the apex face of the rubber projection, and with another end portion in the extension direction of the metal member at a position lower than half of a projection height of the rubber projection.
