PURPOSE:To maintain the neutral conditions of a continuously variable transmission stably which is composed of the combination of a transmission pulley mechanism and a differential gear mechanism. CONSTITUTION:On the back of a mavable sieve for each transmission pulley 16, 31 in a transmission pulley means 15 a pair of cam means changing the winding dia. of belt while contacting/separating between both pulleys 16, 31 to/from each other are disposed, and an interlocking means 44 varying the shift ratio while interlocking both cam means so as to change the belt winding dia. of each pulley to the different direction is arranged. In the control force tranmission path from a control lever 46 to the interlocking means 44 a non- sensitive part 50 is installed to enable no tranmission from the control force of the lever 46 to the interlocking means under the neutral conditions of a continously variable transmission. |
