To provide an elastic crawler that achieves both light weight and durability.SOLUTION: An elastic crawler includes: an endless, belt-like crawler body 2 having a first edge 2a and a second edge 2b in a crawler width direction b; core materials 3 spaced and embedded in a crawler circumferential direction a in the crawler body 2; and a tension member 4 embedded further on a crawler outer peripheral side co than the core materials 3 of the crawler body 2. The tension member 4 includes: a first tension member 4A embedded on a first edge 2a side of the crawler body 2; and a second tension member 4B embedded on a second edge 4b side of the crawler body 2. Each core material 3 includes a first core material 3A. The first core material 3A includes: a first vane part 6A disposed opposite to the first tension member 4A and located in proximity to the first tension member 4A so as to receive a tensile strength F from the first tension member 4A; and a second vane part 6B disposed opposite to the second tension member 4B and located apart from the second tension member 4B so as not to substantially receive the tensile strength F from the second tension member 4B.SELECTED DRAWING: Figure 1
【課題】 軽量化と耐久性とを両立させ得る弾性クローラを提供する。【解決手段】 クローラ幅方向bの第1エッジ2aと第2エッジ2bとを有する無端帯状のクローラ本体2と、クローラ本体2にクローラ周方向aに間隔を空けて埋設された芯材3と、クローラ本体2の芯材3よりもクローラ外周側coに埋設された抗張体4とを含んでいる。抗張体4は、クローラ本体2の第1エッジ2a側に埋設された第1抗張体4Aと、クローラ本体2の第2エッジ4b側に埋設された第2抗張体4Bとを含み、芯材3は、第1芯材3Aを含んでいる。第1芯材3Aは、第1抗張体4Aと対向して配置されかつ第1抗張体4Aから抗張力Fを受けるように第1抗張体4Aに接近して配された第1翼部6Aと、第2抗張体4Bと対向して配置されかつ第2抗張体4Bから実質的に抗張力Fを受けないように第2抗張体4Bから離間して配された第2翼部6Bとを含んでいる。【選択図】 図1
