PURPOSE:To prevent the occurrence of noise and the reduction in durability by providing elastic bodies which elastically support a link connecting body in a definite position so as to be closely in contact with each other, so that respective V-type blocks are energized in the same direction, in the longitudinal direction of pins. CONSTITUTION:A link connecting body 3 is constituted by connecting pins 1 adjacent each other with link plates 2, and pin-mount V-shaped blocks 4 are arranged in the longitudinal direction of the link connecting body 3 and are formed so as to surround it in the lateral direction. Further, the pin-mount V-shaped blocks 4 are constituted by block parts 4a and 4b divided on the surface bisected in the breadth direction of a pulley V-groove 5, and after each pin 1 has been inserted into blind holes 4c, 4d, these block parts are integrated by welding 6. Furthermore, a disk spring 7 is fitted in each pin 1, and each of the pin-mount V-shaped blocks 4 is energized in the same direction, in the longitudinal direction of the pin 1. Accordingly, all the pin-mount V-shaped blocks 4 are aligned in the driving direction of belt, and the occurrence of noise and the reduction in durability can be prevented.
