The second speed change pulley 5 is attached to a control shaft 22 arranged parallel to the driven shaft 2 at the lower part of the driven shaft 2 and reciprocated in a direction perpendicular to the driven shaft 2, and inserted into the V-shaped groove of the second speed change pulley 5. 2 discs 24. The first disc 23 and the second disc 24 are members that forcibly maintain the pitch diameters of the first speed change pulley 4 and the second speed change pulley 5 at predetermined values, respectively, and do not operate both at the same time. That is, when one disc is inserted into the V-shaped groove of the corresponding speed change pulley and pressed against it, the other disc remains inserted into the V-shaped groove of the corresponding speed change pulley and is pressed against the surface of the V-belt. You can wait at close range without contact. For details, see the first speed change pulley 4 from the upper end.
The displacement h1 from the second control shaft 22 to the lower end of the second speed change pulley 5 is inputted to a computer (not shown) every moment, and when the value of h1 changes, the displacement h1 from the second control shaft 22 to the lower end of the second speed change pulley 5 changes. 2 is changed to a value sufficient to place the second disc 24 close to the V-belt without contacting it. Therefore, when the first disk 23 is removed from the position where the first speed change pulley 4 is held at the forced pitch diameter, the second disk 24 is immediately moved to hold the second speed change pulley 24 at the forced pitch diameter. can be operated for.
