To prevent erroneous pairing while preventing wheel separation on the premise that core members of one kind are arranged while the left and right sides are alternately inverted in the crawler width direction thereof.SOLUTION: A core member 3 includes first wheel-separation preventing means 11 on one side in a crawler width direction Y disposed on a core member body 7 and a second wheel-separation preventing means 12 on the other side. The first wheel-separation preventing means 11 includes one first wheel-separation preventing projection 20, 21, projecting from a first side surface S1 and a second side surface S2, respectively, in a crawler circumferential direction X of the core member body 7. The second wheel-separation preventing means 12 includes pairs of second wheel-separation preventing projections 22A, 22B and 23A, 23B, projecting from the first side surface S1 and the second side surface S2, respectively. The first wheel-separation preventing projection 20 (21) of one of the core members 3 adjacent to each other in the crawler circumferential direction X, is sandwiched and held between the pair of second wheel-separation preventing projections 22A, 22B (23A, 23B) of the other core member 3.SELECTED DRAWING: Figure 5
【課題】 1種類の芯材を、そのクローラ幅方向の左右を交互に反転しながら配置することを前提とし、脱輪防止を行いながら誤組を防止しする。【解決手段】 芯材3は、芯材本体7に配されるクローラ幅方向Yの一方側の第1脱輪防止手段11と、他方側の第2脱輪防止手段12とを含む。第1脱輪防止手段11は、芯材本体7のクローラ周方向Xの第1側面S1及び第2側面S2からそれぞれ突出する1本の第1脱輪防止突部20及び21を含む。第2脱輪防止手段12は、第1側面S1及び第2側面S2からそれぞれ突出する一対の第2脱輪防止突部22A、22B、及び23A、23Bを含む、クローラ周方向Xで隣り合う一方の芯材3の第1脱輪防止突部20(21)は、他方の芯材3の一対の第2脱輪防止突部22A、22B(23A、23B)間に挟まれて保持される。【選択図】図5
