PROBLEM TO BE SOLVED: To preclude the possibility of separation with respect to a rubber crawler, even when great driving force in a pitching direction is applied in a core bar. SOLUTION: At least a protrusion 6 extended along a width direction of a rubber crawler 1 is formed on an embedded face of core bar 2 for the rubber crawler 1 to constitute an uneven face, in the core bar 2 for the rubber crawler 1 embedded at a prescribed interval along a longitudinal direction of the endless rubber crawler 1 to be laid width-directionally. Even when great driving force is transmitted to a sprocket engaging part 4 in the core bar 2 to make pitching force act on the core bar 2, a pitching behavior of the core bar 2 inside the crawler 1 is effectively precluded to prevent separation, since the protrusion 6 formed extendedly at least along the width direction of the crawler 1 exists on an embedded face of the core bar 2.
