A ring-shaped elastic endless crawler comprises an elongated belt-shaped elastic crawler body, and a plurality of cords disposed in array and embedded in the crawler body so as to extend in a longitudinal direction of the crawler body. Cord protrudin g portions at each of the ends of the crawler body are divided into groups such that each group has a protruding length different from those of other groups. The endless crawler further comprises a plurality of elastic protrusions for driving the endless crawler that are formed at predetermined intervals in the crawler body longitudinal direction on an inner peripheral surface of the crawler. The cords are embedded into the crawler body so that the ends of co rd protruding portions are located at positions in which said ends and the driving protrusions overlap each other.
