PURPOSE:To increase a transmission load, by engaging a metallic block to the conical contact surface of a pulley, successively connecting the metallic block with an endless state link belt, pulling a following metallic belt through said link belt and transmitting driving power. CONSTITUTION:Link belts 100 are connected in such a manner that link elements 102 of metallic thin plate, drilled with shaft holes in both ends, are parallelly placed in large numbers to the direction of thickness, and their longitudinal one end part is connected in an endless belt state to the other end of the link elements 102, mutually neighboring to the direction of thickness, by a shaft 103 formed with the periphery of a principal part to cylindrical shape. Metallic blocks 1 are connected one by one between the shafts 103 of the link belt 100. The metallic block 1, adapted and engaged to a contact surface 110 of a pulley, transmits driving power of the pulley to the shaft 103 of the link belt 100, and this power is acted to pull the link belt 100 and transmitted to the following metallic block 1. |
