A continuously variable transmission includes: first to third power transmission components; a rolling component; a support shaft for the rolling component; a first guide member that includes a first guide portion for guiding a first protrusion portion of the inserted support shaft; a gear shift member that includes a gear change portion; a first actuator which tilts each rolling component by moving each second protrusion portion along the gear change portion with rotation of the gear shift member at a time an input-output gear ratio is changed; a second guide member that includes a second guide portion for guiding a second protrusion portion of the inserted support shaft; and a second actuator which prohibits rotation of the second guide member during reverse rotation of the first and second power transmission components and allows rotation of the second guide member during normal rotation of the first and second power transmission components.
