<P>PROBLEM TO BE SOLVED: To easily form a rubber crawler to be mounted on a construction machine such as a hydraulic shovel, a farm machine and other crawler vehicles. <P>SOLUTION: The rubber crawler includes an endless belt-shaped crawler body formed of a rubber material, and core metals disposed in the crawler body at intervals in a crawler circumferential direction. The core metal includes a blade part 25 embedded in the crawler body and a protrusion 26 protruding from the blade part 25 toward the inner circumferential surface of the crawler body. The method of manufacturing the rubber crawler includes a connection process of connecting the blade part 25 and the protrusion 26. The connection process includes inserting a convex part 35 formed in one of the blade part 25 and the protrusion 26 into a concave part 33 formed in the other one, and compressively deforming the convex part 35 in its axial direction to increase the diameter in the concave part 33, thereby bringing the convex part 35 into press-contact with an inner wall surface of the concave part 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
