A female screw portion 24 is formed over the entire length of a through hole 23 passing through an axis of an ultrasonic horn 13, first and second male screw portions 25, 26 formed on the ultrasonic horn 13 side of axes of first and second boosters 14, 15 are screwed into the female screw portion 24, the ultrasonic horn 13 and the first and second boosters 14, 15 are fastened coaxially, leading ends 27, 28 of the first and second male screw portions 25, 26 are not in contact with each other inside the through hole 23, and a cutting blade 12 is attached to an outer periphery of a base portion 20 of the ultrasonic horn 13 having a space portion 29 surrounded by an inner wall of the through hole 23 and the leading ends 27, 28 of the first and second male screw portions 25, 26.
A fastening structure of an ultrasonic resonator having an ultrasonic horn which includes a cutting blade on an outer periphery, and first and second boosters respectively coupled to one side and the other side of the ultrasonic horn in the axial direction, the ultrasonic resonator that, by ultrasonic standing waves generated with an ultrasonic transducer coupled to a free end surface of any one of the first and second boosters as a drive source, while oscillating the ultrasonic horn serving as an R/L converter in the radial direction which is orthogonal to the axial direction of the ultrasonic horn, rotates on an axis of the ultrasonic horn and performs ultrasonic machining, wherein
