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