Abstract
A device for supporting an ultrasonic vibration assembly comprises an ultrasonic vibrator, a vibration transmitter coupled to the end of the vibrator coaxially thereto, two flanges provided at a prescribed distance from each other on the outside circumferential surface of the transmitter so as to act as pistons, a cylinder in which the flanges are fitted so as to be movable in the axial direction of the cylinder, and mechanisms for feeding a pressurized fluid to two openings defined between the flanges and both the ends of the cylinder. The cross-sectional area of one portion of the interior of the cylinder is made different from that of the portion of the opening, and one of the flanges is made different in outside diameter from the other thereof and fitted in the end portion.
