PROBLEM TO BE SOLVED: To enable effective drop-off of mud clogged between lugs by improving an outer peripheral surface of a rubber crawler. SOLUTION: The rubber crawler comprises an endless rubber elastic body 1; a steel cord 3 buried in its central part toward a longitudinal direction; and the lugs 5, 6 formed on the outer peripheral surface 8. A projection shape 7 is formed at an area where the steel cord and the lugs intersects with one another and on the outer peripheral surface of the rubber crawler between the adjacent lugs.
