<P>PROBLEM TO BE SOLVED: To provide an easy-to-manufacture core metal for a crawler, which suppresses the oscillation of a track roller during travelling. <P>SOLUTION: A plurality of core metals 20 are arranged to the rubber crawler 10 at an interval in the circumferential direction of the crawler. The core metals 20 include: a pair of wing sections 24 provided in the direction of the crawler width at an interval and extending in the direction of the crawler width; a center section 22 provided between the pair of the wing sections 24 while being shifted in the circumferential direction of the crawler relative to the wing sections 24; and a pair of rail sections 28 provided between the wing sections 24 and the center section 22, extending in the circumferential direction of the crawler, wherein the length of the circumferential direction of the crawler is longer than the center section 22, extending in the direction S2 reverse to the direction S2 shifted to each of the wing sections 24 further than the center section 22, and constituting at least a part of the rolling surface 32 on which the track roller 104 rolls. <P>COPYRIGHT: (C)2012,JPO&INPIT |
