PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission in which the length of an inside hole in an input shaft formed to feed oil to each oil chamber of a hydraulic pressure-applying device is minimized to enable the ensuring of good workability and sufficient strength. SOLUTION: The toroidal continuously variable transmission is provided with an input shaft 1 input for the rotary force from an engine, an input side disk 2 coupled with the input shaft 1 to integrally rotate with the input shaft 1, an output side disk receiving the rotary force of the input side disk 2 at a predetermined change gear ratio via a power roller installed between the input side disk 2 and the hydraulic pressure applying device 30A which is arranged in the rear of the input side disk 2 and presses the input side disk 2 in the axial direction. The pressure applying device 30a has a plurality of oil chambers 67, 70. All feeding port 92 to feed oil into each oil chamber 67, 70 is formed to be almost on the same circumference.
