PCT No. PCT/JP92/00691 Sec. 371 Date Jan. 24, 1994 Sec. 102(e) Date Jan. 24, 1994 PCT Filed May 27, 1992 PCT Pub. No. WO92/21549 PCT Pub. Date Dec. 10, 1992The present invention relates to a highly elastic rubber crawler mounted on a mobile working machine, the crawler having improved durability, easily passing around a drive wheel and inflicting no damage on a paved road surface. Specifically, a highly elastic rubber crawler defines engageable holes in the main body of the crawler into which the tops of teeth of a drive wheel are fitted, engageable portions between engageable holes for meshing with the roots of the teeth of the drive wheel, projections at both sides of the engageable portion for preventing the drive wheel from falling off the crawler, and lugs projecting from an outer peripheral surface. The inner peripheral layer including the projections is formed of highly rigid urethane rubber, the outer peripheral layer including the lugs is formed of vulcanized rubber or an equivalent elastic member, and, on the inner peripheral layer in the vicinity of a border surface between the inner peripheral layer and the outer peripheral layer in the main body of the crawler, reinforcing cords having high strength are aligned and embedded in the circumferential direction of the crawler at both sides of the engageable holes, and other reinforcing cords are embedded at the engageable portions in a direction perpendicular to the circumferential direction.
