PROBLEM TO BE SOLVED: To protect the rubber projections from wear, breakage, and the like and to improve life of the rubber crawler by embedding a wear resistant member in a rubber projection in the width direction of a rubber crawler, and locating the innermost end of the exposed portion of the wear resistant member above the base portion of the rubber projection. SOLUTION: A rubber lug 6 is formed on an outer peripheral surface of an endless rubber elastic body 1, which is a rubber crawler. On an inner peripheral surface of the endless rubber elastic body 1, rubber projections 2 used for transmission of driving force or for prevention of deviation from rolling wheels are formed at a certain pitch. A wear resistant member 10 is embedded at the rubber projection 2 in a width direction of the endless rubber elastic body 1. An innermost end 10a of an exposed portion of the wear resistant member 10 is located above a base portion 2a of the rubber projection 2. Consequently, the rubber projections 2 projecting from the inner peripheral surface of the endless rubber elastic body 1 are protected from wear, damage, and the like. Accordingly, the generation of crack at a boundary of the rubber projections 2 and the endless rubber elastic body 1 is reduced.
