PROBLEM TO BE SOLVED: To provide an elastic crawler capable of reliably preventing run-off of a tracker roller by increasing the strength and durability of a driving projection. SOLUTION: A hollow reinforcing core 10 having an opening end 10a with the crawler width direction being the longitudinal direction thereof is embedded inside a driving projection 6 which is formed on an inner circumferential surface 7b of a crawler body 7. A filler 11 (an elastic body) is embedded inside the reinforcing core 10. By integrating the filler 11 with a component 12 of the driving projection 6, the strength and durability of the driving projection 6 are increased, and run-off of a tracker roller 5 is reliably prevented thereby.
