PURPOSE:To improve the durability of a friction transmitting V-block by installing and fixing a number of friction transmitting V-block pieces onto the both edge parts of a link chain connecting pin, thus preventing the generation of a slip between the V-block and a chain. CONSTITUTION:A friction transmitting V-block 1 which winds in squeezed state into the V-groove of a pulley transmits the driving revolution force of the pulley to a holding pin installed onto the block and a fixed pin, and each traction forces of the holding pin 5 and fixed pins 7a and 7b is transmitted to the whole of a chain through a ring plate, and a motive power is transmitted by the pulling force of the chain. Therefore, the friction transmitting V-block 1 is provided with the function as the medium for transmitting the driving force of the pulley onto a chain link plate. |
