PROBLEM TO BE SOLVED: To provide a rubber crawler capable of largely enhancing durability of an engagement part of the rubber crawler with a drive sprocket and effectively preventing generation of impact/contact noise of the drive sprocket to the engagement part. SOLUTION: In the rubber crawler extending in an endless form, having a lug 2 applied to a road surface on an outer peripheral surface and having the engagement part 5 with the drive sprocket 3 on an inner peripheral surface, a reinforcement layer 7 is buried/arranged over the approximately whole width and a core metal 8 extending in a width direction is buried/arranged with a predetermined pitch in a circumferential direction at an inner peripheral side of the reinforcement layer 7. A central portion 9 of the core metal 8 for supporting drive force of the drive sprocket 3 is completely buried in a rubber elastic body 10 contributing to absorption of drive energy without exposure of the core metal 8 (9).
