PROBLEM TO BE SOLVED: To improve positioning accuracy of connecting pins with respect to link plates while maintaining strength of the connecting pins. SOLUTION: In this endless belt for transmission, the large number of link plates 1 are connected with each other by the connecting pins 2A, 2B, and ends of the endless belt for transmission are made rotatably endless by rolling of rolling faces 21 of each of the pins 2A, 2B. In the outer peripheral face portions opposing to inner peripheral faces of fitting holes 13 of the link plates 1, each of the connecting pins 2A, 2B has two flat faces 22 extending in the pin axial direction and a projecting part 2a sandwiched between the flat faces 22. The flat faces 22 of the connecting pins 2A, 2B abut on the link plates 1, and due to this structure, the connecting pins 2A, 2B are highly positioned. The projecting parts 2a function to maintain the strength of the pins 2A, 2B. COPYRIGHT: (C)2006,JPO&NCIPI
