Abstract
A V-ribbed belt A is made up of a compression rubber 3, an adhesion rubber 1 laminated to the upper surface of the compression rubber 3, and a plurality of tension members 2 fixed by rubber of the adhesion rubber 1 to be held in place in the adhesion rubber 1 and arranged in the direction of the length of the belt. The upper surface of the adhesion rubber 1 is covered with a covering fabric-rubber composite B. All the rubber sections of the composite B are composed of a rubber compound formed by incorporating 5 to 15 phr of an adhesive prepared by mixing resorcinol or denatured resorcinol with a methylene donor, into H-NBR. The adhesion rubber 1 and the compression rubber 3 are composed of a rubber compound whose principal components are ACSM and carbon for achieving good belt back-face drive in high-temperature environment.
