PROBLEM TO BE SOLVED: To provide a rubber crawler having excellent durability by eliminating any separation phenomenon of an adhesive boundary exposed part A in a rubber lug forming a contact surface of rubbers in an endless structure. SOLUTION: In an endless structure of the rubber crawler, the rubber crawler comprises a long rubber elastic band 1 with ends, steel cords 2 embedded in the longitudinal direction of the rubber elastic band, and rubber lugs 4, 4a, the steel cords protruded from both ends of the rubber elastic band 1 overlap each other, and both ends 1a, 1b of the long rubber elastic band 1 with ends are integrally vulcanization-molded. An adhesive boundary exposed part A in the rubber lug forming a contact surface of rubbers during the integrated vulcanization-molding is formed on an inclined side face of the rubber lugs.
