摘要

A hydraulic pressure controller (52) is provided between a hydraulic actuator (391) for changing the effective radii of a drive V-pulley (30) mounted on an input shaft (14) and a driven V-pulley (31) mounted on an output shaft (15) and a hydraulic pump is provided for supplying a hydraulic pressure to the hydraulic actuator (391, 392). The hydraulic pressure controller (52) is controlled by an input torque sensor and a speed change ratio sensor, whereby the hydraulic pressure supplied to the hydraulic actuator (39) is automatically controlled in proportion to the input torque received by the input shaft (14) and the speed change ratio between the input and output shafts (14, 15).
