ABSTRACT:
A torque transmission belt means comprises a metallic ring which extends around a driving pulley and a driven pulley and a plurality of blocks made of hard material, which are linked up by the ring so as to be shiftably engaged therewith. Each block is provided with a concave portion in the front surface or the rear surface in the moving direction of the ring and an elastic member is fixed to the front surface or the rear surface of a back plate portion of each block, which forms a bottom of the concave portion so that each elastic member is contacted with the back plate portion of the adjacent block. Since each block is contacted with the adjacent blocks through the elastic members, the torque transmission belt means silently operates.
