Abstract
A continuously variable transmission having a continuously variable transmission mechanism including an input member, an output member, and a rotary member sandwiched therebetween, transmitting torque between the input member and the output member by means of frictional forces generated by pushing the input member and the output member against the rotary member, and continuously varying a transmission gear ratio between the input member and the output member, an axial force generating portion which rotates in one direction to generate a first axial force for pushing one of the input member and the output member toward the other and rotates in the other direction to generate a second axial force opposite to the first force, and an opposite axial force transmitting portion for transmitting the second force to the other of the input member and the output member when the axial force generating portion generates the second force.
