Abstract

PURPOSE:To reduce noise at the time of chain belt power transmission by reducing the bending pitch at the time of wrapping round a pulley to the half of the conventional pitch, so that a polygon formed by the respective pitches approach a circle. CONSTITUTION:A block 70 positioned between tabs 44, 54 has rolling surfaces 73, 74 of both block piece 71, 72 brought into contact with each other to form the second pivot. When a chain belt 30 is wrapped round a pulley, the belt is bent by a pin 60 forming the first pivot, and the block 70 is bent between a pair of block pieces 71, 72. That is, both block pieces 71, 72 are rolled along the contacting rolling surface 73, 74 to bent according to the diameter of wrapping round the pulley. Thus, the bending pitch P at the time of wrapping round the pulley is a distance between the pin 60 and the block 70, which is half the conventional pitch. Accordingly, a polygon formed by the respective pitches approaching a circle to reduce noise at the time of power transmission.
