PURPOSE:To improve the durability of a chain type belt by receiving the load applied from a power transmission block by each link plate in distribution and preventing the concentration of load onto a pair of link plates. CONSTITUTION:A power transmission block 32 is fixedly supported by a block supporting hole, and the part close to the engagement edge surface 31 is supported by the a pair of third inner link plates 7 and 7, and the intermediate part is supported by the second inner link plates 6 and 6. Therefore, on the engagement with a pulley 21, load is distributed onto the third inner link plates 7 and 7 and the second inner link plates 6 and 6, and the concentration of load onto only the outside link plate can be prevented, and the durability of a chain type belt 1 can be improved. |
