PURPOSE:To improve the durability of a load block and a link of an endless belt by holding link coupling pins in contact with coupling pin pressing blocks, and disposing paired load blocks which are adapted to cover the link coupling pins and have contact surfaces with a driving pulley between the pressing blocks. CONSTITUTION:Link pieces 3 of an endless belt are held by bar-like pins P, and the respective bar-like pins are clamped by contact portions of the respective bar-like pin pressing blocks 6. A pair of load blocks 7, 8 which are adapted to cover the respective bar-like pins and have contact surfaces with a driving pulley are disposed between the pressing blocks. The load blocks are always paired to increase the number of contact surfaces with the driving pulley, so that the durability is improved. As the link pieces 3 do not contact the pressing blocks 6, the durability of links is improved. |
