Abstract
An elastic endless crawler according to the present invention comprises an annular belt-shaped elastic crawler body and a plurality of cords with ends, said cords being disposed substantially parallel with one another at predetermined intervals and embedded in the crawler body, wherein one end and the other end of each cord are overlapped, as seen from the belt side. Further, at at least one of a crawler inner peripheral side and a crawler outer peripheral side, there are provided a plurality of members for holding the cord ends within the crawler body. As a result, a chance of free ends of embedded steel cords protruding out from the rubber body during use of the rubber crawler and a chance of the rubber crawler running off of a unit for driving for rotation thereof can be eliminated.
