PROBLEM TO BE SOLVED: To provide a crawler which is superior in durability and suppresses the formation of a crack near the end of a core bar effectively. SOLUTION: The crawler K comprises a crawler body 11 of an endless belt shape, core bars 12 embedded in the crawler body 11 longitudinally of the belt shape at every a prescribed distance, and lugs 13 projected on the crawler body 11 longitudinally of the belt shape at every a prescribed distance. The end 12a of each core bar 12 is formed into an end face 112a that has a radius of curvature of 3 mm or more. In addition, a reinforcing fiber layer 1 and an elastic layer 2 with high hardness are formed at the outside of the end 12a of the core bar 12 to be curved in correspondence to the end face 112a.
