PURPOSE:To reduce speed change operating force at the maximum reduction side by fixing a speed change lever arranged on a screw unit provided at the pivot shaft end of trunnion system while inclining by specific angle against the rotary axis of power roller. CONSTITUTION:Input shaft 1 is fitted with an input disc 2 while an output shaft and an output disc (not shown) are arranged in front. Two power rollers 3 are arranged between the input disc 2 and the output disc while supported rotatably by a trunnion 4. Speed change levers 11 are fixed while facing each other while the coupling link 12 of respective speed change lever 11 is coupled through a balance link 13 and fixed while inclining by the angle theta against the direction of the rotary axis of power roller 3. |
