Torque transmission belt means

摘要

A torque transmission belt means which is extended between a driving pulley and a driven pulley for transmitting a driving force from the driving pulley to the driven pulley. The torque transmission belt means comprises a plurality of ring-shaped metallic strips which are superimposed on each other, and two kinds of blocks which are arranged along the metallic strips so as to be shiftably engaged therewith. Only one kind of blocks are contacted with said pulleys and the other kind of blocks are bevelled on opposed surfaces facing to the direction of the movement so that they can tilt with respect to one kind of blocks when they are entrained around the pulleys.
