PROBLEM TO BE SOLVED: To propose a rubber crawler structure preventing breakage of various kinds of auxiliary cords embedded in a rubber crawler, particularly to provide a technology for preventing breakage of the auxiliary cords caused by rolling of a rolling wheel on the inner peripheral surface of a coreless rubber crawler. SOLUTION: The rubber crawler comprises an endless rubber elastic body 1; main cords 2 embedded lined up in the longitudinal direction; a plurality of bias cords 3a, 3b embedded in relation to the main cords; or further 0°ply cords 4 embedded at a right angle to the embedded direction of the main cords 2; and a lug 6 formed at the outer peripheral surface, wherein the rolling wheel 10 rolls on the inner peripheral surface, and the thickness of rubber 9 between the main cords 2 and bias cords 3a, 3b and/or 0°ply cords 4 corresponding to the edge part 10a of the rolling wheel 10 is made thicker than rubber thickness between both of the cords at the other part.
