ABSTRACT:
In a rubber crawler, lags are generally are formed on the outer surface of an endless belt-like elastomer, and rubber projections for transmission of driving force and prevention of the rubber crawler from coming of off from a wheel are formed on the inner surface of the elastomer at regular pitches. Rein forcing cord layers are embedded in the elastomer along its longitudinal direction. An abrasion resistant member is embedded in the rubber projection along the width direction of the rubber crawler. Its both end portions are exposed at the sides of the rubber projection. The abrasion-resistant member has a central portion having a small diameter and a pair of end portions connected to the ends of the central portion and having a large diameter. In the exposed portion of the end portion which is exposed at the side surface of the rubber projection, its most interior portion in the radial direction is positioned above the base portion of the rubber projection. The rubber crawler of the invention includes thicker portions formed to extend from the width end of the elastomer over the end of the reinforcing cord layer.
