Abstract
A loading cam for continuously variable transmissions includes cam rollers contacting an input disk and a cam flange to press the input disk in the axial direction of a main shaft of the transmission upon shifting, a holding member engaged with the cam flange to hold the cam rollers, and a cover attached to the holding member. The cover cooperates with the holding member to define a passage for supplying lubricating oil for the cam rollers.
