PROBLEM TO BE SOLVED: To provide a rubber crawler which hardly generates a crack on an outer peripheral surface thereof. SOLUTION: Ends 13A, 13B on a width direction center side of lugs 12A, 12B are superimposed on a projection part (a broken line part in Fig.) of a guide jut 16. Since the ends 13A, 13B are superimposed on the projection part of the guide jut having high rigidity, the ends bend less than other portions when the track is wrapped around a sprocket etc, and the concentration of strain at the ends 13A, 13B is prevented. Therefore, the generation of cracks at the ends 13A, 13B of the lugs 12A, 12B can be prevented. COPYRIGHT: (C)2009,JPO&INPIT
