PROBLEM TO BE SOLVED: To achieve a structure capable of suppressing pressing force required to secure surface pressure of each traction part in a G/N (Geared/Neutral) state and in the vicinity part, in a continuously variable transmission capable of achieving the G/N state. SOLUTION: A toroidal continuously variable transmission 3a constituting this continuously variable transmission by being combined with a planetary gear unit 4a includes input discs 7a and 7b and output discs 9a and 9b at a center part and both end parts, respectively. The output shaft 9b part of them includes a hydraulic pressing device 28 for generating shaft force to secure surface pressure of each traction part to be a rolling contact part between each disc 7a, 7b, 9a and 9b and each peripheral surface of each power roller 8a.
