A continuously variable tranmission having a continuously variable transmission mechanism for transmitting torque between an input side and an output side by means of frictional forces generated by pushing the input disc and the output disc against the planetary balls and continuously varying a transmission gear ratio between the input side and the output side includes a second group of helical gears capable of generating a first axial force for pushing the input disc toward the output disc a first group of helical gears capable of generating a second axial force for pushing the output disc toward the input disc, and a thrust bearing and a central shaft for transmitting, when an opposite force in such a direction as to move the input disc away from the output disc and opposite force to the first force is generated on a side of the input disc, the opposite force to the output disc.
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,
