PURPOSE:To reduce the transmission torque and decrease the contact force by controlling the transmission torque control means and contact force generating means at the time of speed change by means of a speed change actuator. CONSTITUTION:A V-belt dreven type nonstage transmission CVT has a clutch mechanism 300, and consists of shaft force generating mechanisms 8 and 9 as contact force generating means provided to an input pulley 3 and output pulley 4 and a transmission torque control means 200, and operates the transmission torque control means at the time of speed change and further controls the contact force generating means. Thus, the transmission torque between the speed change actuator and the driving parts is reduced and the contact force is also decreased to enable the speed change actuator to be miniaturized. |
