Zusammenfassung:PROBLEM TO BE SOLVED: To suppress the occurrence of judder vibration during a transition period of power transmission with friction slide.SOLUTION: A control device of a friction power transmission mechanism includes a friction transmission RT, and a roller pressing force feedback control system 7 that performs feedback control on pressing force so that the actual slide speed of the friction transmission RT becomes a target slide speed. In the control device of the friction transmission RT, the roller pressing force feedback control system 7 comprises a judder controller 74 designed so as to eliminate a phase advance at the feedback control.
