Patent ID: 8382636

Claim:
A continuously variable transmission comprising 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, wherein the continuously variable transmission includes a first axial force generating portion capable of generating a first axial force for pushing the input member toward the output member, a second axial force generating portion capable of generating a second axial force for pushing the output member toward the input member, and an opposite axial force transmitting portion for transmitting, when an opposite axial force in such a direction as to move the input member away from the output member and opposite force to the first force is generated on a side of the input member, the opposite force to the output member to push the output member toward the input member.
