PROBLEM TO BE SOLVED: To provide a rubber crawler with its rigidity being gradually changed in the width direction of the rubber crawler by incliningly arranging an end of a bias cord embedded on the inner and outer sides with respect to the width end of a main cord. SOLUTION: The rubber crawler comprises an endless rubber elastic body 1, a main cord embedded along its longitudinal direction, and a bias cord embedded on the inner side and/or the outer side. The rigidity in the width direction of the rubber crawler is gradually changed in the width direction by successively changing the positions of ends 30, 4a0, 4b0 with respect to the end width of the main cord.
