PROBLEM TO BE SOLVED: To provide a rubber crawler with remarkably improved durability by effectively avoiding peel damage at a center lug section causing the peel damage of a grounding lug. SOLUTION: A surface vertical to the advance direction of a center lug 9 provided at the buried position of a core bar 3 for connecting the grounding lugs 8A, 8B formed at a specific interval in a longitudinal direction at both sides of an outer-periphery grounding section of the rubber crawler 1 is formed on a curved surface 9A in terms of side view. Thus the configuration of the curved surface can cleverly handle large resisting force due to obstacles such as gravel from a road surface for moderately dispersing even if the surface 9A being vertical to the advance direction of the center lug 9 close to, especially the engagement section of a sprocket receives the resisting force when the rubber crawler 1 that repeats advance and retreat is driven. As a result, the peel is not generated in the center lug 9 at an early stage, and spread to the grounding lugs 8A, 8B connected to the center lug 9 is avoided for lengthening service life.
