To provide a rubber composition for crawler that can achieve both of wear resistance and low heat build-up properties at high levels while maintaining excellent cut resistance.SOLUTION: A rubber composition for crawler contains a rubber component containing styrene-butadiene rubber, inorganic filler such as carbon black, and a compound represented by the following formula (I) (where A is an aryl group with at least two polar groups, where the polar groups may be the same or different. R1 and R2 independently represent at least one substituent selected from the group consisting of a hydrogen atom, an acyl group, an amide group, an alkyl group, a cycloalkyl group and an aryl group, and the substituent may have at least one of O, S and N atoms).SELECTED DRAWING: None

    【課題】良好な耐カット性を維持しつつ、耐摩耗性及び低発熱性を高いレベルで両立できるクローラ用ゴム組成物の提供を目的とする。【解決手段】スチレンブタジエンゴムを含有するゴム成分と、カーボンブラック等の無機充填材と、下記式(I)で表される化合物とを含むことを特徴とする。(式中、Aは、アリール基であり、少なくとも2つの極性基を有し、該極性基は同じであっても、異なっていてもよい。R1及びR2は、それぞれ独立して、水素原子、アシル基、アミド基、アルキル基、シクロアルキル基及びアリール基からなる群から選択される少なくとも一種の置換基であり、さらに、該置換基は、O、S及びN原子のうちの一種以上を含んでいてもよい。)【選択図】なし
