An elastic endless crawler has cords arranged in a crawler body composed of elastic materials such as an endless belt-like rubber material in and along the longitudinal direction of the crawler body. Main cord layers are embedded in the crawler body to restrain elongation of the crawler body in the longitudinal direction. Bias cord layers are also embedded in the crawler body. The bias cords of the bias cord layers are so arranged that they incline reciprocally in mutually-opposite directions in relation to a straight line measured in the transverse direction of the crawler body which intersects the longitudinal direction of the crawler body at a right angle.
