PROBLEM TO BE SOLVED: To provide an endless structure of a rubber crawler arranged so as to avoid concentration of the strain to the rubber in the neighborhood of the steel cord tip, capable of specifying the layout at the steel cord tip, and accordingly specifying the shape of a core and also the shape of a lug, and thereby enhancing the lifetime of the rubber crawler. SOLUTION: The endless structure of the rubber crawler is embodied so that the tips of steel cords 3 at the ends of an end-equipped crawler base 1 are overlapped on each other and subjected to vulcanization bonding, wherein the cord tip 3a positioned at the periphery is located right over the core 20, and the front-left width W20 of the core is made smaller than the front-left width W2 of the other cores 2.
