Zusammenfassung:PROBLEM TO BE SOLVED: To provide an oscillation actuator capable of simplifying a structure that supplies lubricant to a contact portion between a rotator and an oscillator.SOLUTION: An oscillation actuator 101 includes: a roller 1, an oscillator 2 having a first contact face 2a1 and a second contact face 2b1 in contact with the roller 1; a piezoelectric element 3 that oscillates the oscillator 2; a preload member 8 that pressurizes the roller 1 on the oscillator 2; and a lubrication member 10 provided in the vicinity of the first contact face 2a1 and the second contact face 2b1 of the oscillator 2 and in contact with the roller 1.
