Rubber track, rubber track assembly, and, rubber crawler production method

摘要

PPROBLEM TO BE SOLVED: To provide a rubber crawler in which a positional accuracy of a metal core is favorable by regulating movement in a metal core longitudinal direction and a metal core short-side direction when a rubber is vulcanized to be attached to the metal core, a rubber crawler assembly, and a method of manufacturing rubber crawler. PSOLUTION: The metal core 15 forming the rubber crawler includes: a pair of projections 16 projecting toward an inner circumferential surface side of the rubber crawler; a regulated portion 26 formed between the projections 16 and brought into contact with a mold 30 to regulate the movement in the metal core short-side direction when the projections 16 are aimed downward and the metal core 15 is displaced at a predetermined position of the mold 30 for molding and vulcanizing the rubber crawler; and recesses 22 formed on distal ends of the projections 16 and abutting on the mold 30 to support the metal core 15 when the projections 16 are aimed downward and the metal core 15 is displaced at a predetermined position of the mold 30.
