PROBLEM TO BE SOLVED: To provide a high-load transmission belt made of hydrogenated nitrile rubber in which Aramid short fibers and carbon black are included in certain amounts so as to give the belt a sufficient hardness and unlikelihood to cause cracking with repetitive bending, capable of eliminating rattling between the center belts and the block, and excellent in the resistance against bending and the heat resistance. SOLUTION: The high-load transmission belt 1 is structured so that a plurality of blocks 2 are fitted fast at the specified pitch in the longitudinal direction of the center belts 3a and 3b, wherein the rubber composition of the center belts 3a and 3b is 10-25 parts by weight Aramid short fibers and 60-80 parts by weight carbon black nitrile rubber with respect to 100 parts by weight hydrogenated nitrile rubber.
