To provide a rubber crawler in which breakage or deformation of a tension member is suppressed and which therefore has improved durability.SOLUTION: A rubber crawler 2 is provided that is wound around a driving wheel 3 and transmits driving force. The rubber crawler includes: a crawler body 4 made of rubber; a core material 5 embedded in the crawler body 4 at an interval in a circumferential direction a, and made of a material harder than rubber; and a tension member 6 embedded on more crawler outer peripheral side than the core material 5 of the crawler body 4 and extending in the crawler circumferential direction a. An opposing surface region 12 facing the tension member 6, of the core material 5 includes, in the crawler circumferential direction a, a first end region 12A on one side, a second end region 12B on the other side, and an intermediate region 12C therebetween. When the rubber crawler 2 is wound around the driving wheel 3, a distance d1 between the first end region 12A and the tensile member 6 in a crawler thickness direction c is twice or more a distance d2 between the intermediate region 12C and the tensile member 6 in the crawler thickness direction c.SELECTED DRAWING: Figure 4
【課題】 抗張体の破損又は変形を抑制し、耐久性を向上させたゴムクローラを提供する。【解決手段】 駆動力を伝達するための駆動輪3に巻き掛けられるゴムクローラ2である。ゴムからなるクローラ本体4と、クローラ本体4にクローラ周方向aに間隔を空けて埋設されかつゴムよりも硬質の材料からなる芯材5と、クローラ本体4の芯材5よりもクローラ外周側coに埋設されてクローラ周方向aに延びる抗張体6とを含んでいる。芯材5の抗張体6に面する対向面領域12は、クローラ周方向aにおいて、一方側の第1端部領域12Aと、他方側の第2端部領域12Bと、これらの間の中間領域12Cとを含んでいる。ゴムクローラ2が駆動輪3に巻き掛けられたときに、第1端部領域12Aと抗張体6とのクローラ厚さ方向cの距離d1が、中間領域12Cと抗張体6とのクローラ厚さ方向cの距離d2の2倍以上である。【選択図】 図4
