Continuously variable transmission

A continuously variable transmission including a first disk unit with a first guide slot, a second disk unit with a second guide slot which the first guide slot crosses, and a guide member provided to move along the first guide slot and the second guide slot in response to relative rotation of the second disk unit to the first disk unit, the continuously variable transmission comprising:

• a rotation driving unit rotating any one of the first disk unit and the second disk unit with respect to the other one,
• wherein the rotation driving unit includes
• a barrel cam member,
• a linear movement member linearly moving in response to rotation of the barrel cam member,
• a driving cam member in which a driving cam profile is formed, linearly moving together with the linear movement member, and
• a driven cam member rotatably in which a driven cam profile that contacts the driving cam profile and converts the linear motion of the driving cam profile into the rotary motion is formed, being connected integrally with any one of the first disk unit and the second disk unit and selectively rotating in response to the linear movement of the driving cam member.
