PURPOSE:To allow only a split crawler at a repair position to be easily replaced and increase the strength of the whole crawler by dividing the crawler at multiple positions in the longitudinal direction and providing junction sections on both ends of the core wire portion of the split crawler respectively. CONSTITUTION:In a rubber crawler 6, multiple reinforcing steel wires 9 are buried in the width direction of a rubber endless belt-shaped body 7, and many core metals 8 serving as coupling members of drive rollers are arranged in the longitudinal direction. A lug 8a guiding a driven roller is formed at the center in the width direction of the core metal 8, and a hole 7a with which the tip of the driven roller is engaged is formed between the core metals 8. In this case, the crawl 6 is divided at multiple positions in the longitudinal direction, and connecting fittings 10 are fitted on both ends of steel wire portions 9A, 9A' of split crawlers 6A, 6A' respectively. Pins 11 are inserted into holes 12 of the connecting fittings 10 to connect the split crawlers 6A, 6A' to each other.
