Abstract: An ultrasonic resonator support structure 10 including a holder 17 supports an ultrasonic resonator 16 at both sides such that the ultrasonic resonator 16 is rotatable to the holder 17. The ultrasonic resonator 16 includes an ultrasonic horn 13 with a machining tool 12 attached, and a first booster 14 and a second booster 15 coaxially fixed one by one to both ends in the axial directions of the ultrasonic horn 13. The holder 17 has a rolling bearing mechanism 18 that rotatably supports the first booster 14 side of the ultrasonic resonator 16 and a gas bearing mechanism 19 that rotatably supports the second booster 15 side of the ultrasonic resonator 16.
