    • A toothed belt includes: a belt main body in which a plurality of cords are arranged side by side in a widthwise direction of a rubber layer; a plurality of teeth portions formed at one surface of the belt main body; and a tooth cloth covering surfaces of the teeth portions. A cloth base material is obtained by impregnating a surface layer rubber composition into an original canvas and by forming a surface layer, and an adhesion layer rubber composition is attached to one surface of the cloth base material to form an adhesion layer, thus forming the tooth cloth. The rubber layer contains: HNBR including HNBR in which a Mooney viscosity at 100° C. is in a range of from 100 to 160; and a polymer alloy obtained by finely dispersing zinc methacrylate in HNBR. The rubber layer and rubber compositions preferably contain hydrogenated carboxyl NBR.
    • 齿形带包括:带主体,其中多根帘线沿橡胶层的宽度方向并排布置; 形成在所述带主体的一个表面的多个齿部; 以及覆盖齿部的表面的齿布。 通过将表层橡胶组合物浸渍到原始帆布中并形成表面层而获得布基材,并且将粘合层橡胶组合物附着到布基材的一个表面上以形成粘合层,从而形成牙齿 布。 橡胶层含有:HNBR,其包含HNBR,其中100℃下的门尼粘度在100至160的范围内; 和通过在HNBR中精细分散甲基丙烯酸锌得到的聚合物合金。 橡胶层和橡胶组合物优选含有氢化羧基NBR。
