PROBLEM TO BE SOLVED: To provide an oscillation wave unit, e.g. an oscillation wave motor, having a long durable time and generating a large torque. SOLUTION: This oscillation wave unit comprises an oscillator group where a plurality of oscillators 1 provided, on the opposite sides in the axial direction, with drive sections 3, 4, 5 for forming a drive wave are arranged coaxially, a plurality of contactors 2 coming into pressure contact with the drive sections, and members 19a, 19b, 19c, for holding the oscillator group. The plurality of oscillators are driven to move relative to the plurality of contactors in same direction. |
