RUBBER CRAWLER

PROBLEM TO BE SOLVED: To provide a rubber crawler that effectively prevents a crawler end from being bent or deformed and prevents core end cracks, without reducing productivity of the rubber crawler.SOLUTION: The rubber crawler is formed by embedding a plurality of cores in an endless rubber elastomer. High-hardness rubber harder than other inner periphery rubber is provided in at least a position where the core is embedded and on the side inner than the core. The high-hardness rubber is arranged in a range that covers the inside and outside in the width direction of the rubber elastomer, with respect to the position corresponding to the edge of the cores, on the inner periphery of the endless rubber elastomer.
