PURPOSE:To prevent noise from being produced by making link mount V-shaped blocks have elasticity in the longitudinal direction of pins as well as arranging elastic portions for preventing pin mount V-shaped blocks from tilting around the pins. CONSTITUTION:Forming a link mount V-shaped block 5 with a plate spring, its outer end in the radial direction of a pulley is made of a corrugated form in the direction of width of a V-groove of the pulley to set a corrugated plate spring 5a. This corrugated plate spring 5a, squeezed between the pin mount V-shaped blocks 4 due to part of transmission power in the pulley's V-groove, increases the width of the link mount V-shaped block 5 in the direction of the pulley axis corresponding to the decrease in the height of corrugation. This makes the link mount V-shaped block 5 frictionally engage with side surfaces 6a of the pulley's V-groove.
