A toroidal continuously variable transmission is provided with a power roller 8 which is gripped between input/output disks 5, 6 arranged on the same axis, a cam flange 2 which is disposed on the same axis as the input disk 5 and is connected to an input shaft 1, and cam rollers 3 which are gripped between the cam flange 2 and the rear face of the input disk 5. Bearings 41, 44, 45 are interposed in the contact position on the long radius end face 3b of the cam roller 3 and the inner circumference of the retainer 4. These bearings allow the reduction of frictional resistance on the contact point of the cam roller 3 and the retainer 4 and improve the torque transmission capacity and component lifespan of the toroidal continuously variable transmission.
