PROBLEM TO BE SOLVED: To provide a high load transmission belt having a long service life, which reduces frictional resistance of a block and a pulley when the block gets in the pulley or gets out of the pulley when running the belt while being wrapped around the pulley, hardly generates block rocking to a center belt, and reduces problems including generation of vibration, noise and heat caused by friction of the block and the pulley and rocking of the block. SOLUTION: The high load transmission belt consists of an upper beam 11, a lower beam 12 and the block 2 having a groove for inserting the center belt 3b surrounded by a pillar 13, and a recessed groove 22 is provided in a side surface 2b of the upper beam 11.
