<P>PROBLEM TO BE SOLVED: To provide an elastic crawler improving ride quality by suppressing a core metal from being inclined with a load from a rolling wheel in traveling. <P>SOLUTION: A rubber crawler 10 includes a rubber crawler body 12 formed of a rubber material in an endless belt shape, a plurality of core metals 14 which are buried circumferentially in the rubber crawler body 12 at intervals in the crawler, extended in the crawler width direction, and receive a load from the rolling wheel 102 passing the crawler inner peripheral side, and a plurality of lugs 50, 52 which are projected at the position corresponding to the core metals 14 on the outer peripheral surface of the rubber crawler body 12 and are alternately disposed circumferentially on right and left in a crawler across the center line CL of the crawler width direction of the core metals 14 viewed from the crawler outer peripheral, and wherein ends 51E, 53E at the center line side of the crawler width direction of top surfaces 51, 53 contacting to a ground are positioned on the central line CL or over the central line CL and the top surfaces 51, 53 circumferentially adjacent to the crawler viewed from the crawler width direction circumferentially continue in the crawler. <P>COPYRIGHT: (C)2012,JPO&INPIT |
