Abstract
In an ultrasonic vibrator, a plurality of electrode pairs, each including electrodes halved on one surface, are arranged in the circumferential direction so as to constitute an electrostrictive element. The electrostrictive element is held and tightened by a vibrator and a metal member. The vibrator is provided with foot portions divided in a number of divisions coincident with the number of the electrode. The halved electrodes of the electrode pairs are connected while parallel in matching with the circumferential position, and AC voltages controlled in relative phase or relative amplitude are applied to respective electrodes. Various vibrations are generated in the vibrator, and the elliptic rate can be controlled during control of the vibration direction or generation of elliptic vibration.
