PROBLEM TO BE SOLVED: To lower the cost required for controlling a pair of pulleys and to improve functions. SOLUTION: A torque sensor 11 installed to an input shaft of a continuously variable transmission reduces a drain flow rate so as to increase a pressure inside a tube 20 when a transmission torque is increased. A valve 25 is provided with a function increasing a pressure of a tube 19 higher than that of the tube 20, 29, 30. Fluid inside the tube 19 is fed from a speed change ratio regulating value 10 to pulleys 1, 2. |
