によって内刃14が構成されている。Therefore, in the above configuration, a drive power source whose phase is controllable is connected to the common electrode plate 40 and the electrode plates 37 and 38, and the drive frequency is adjusted to the flexural resonance frequency. Then, by driving the phase difference to 0, the excitation voltage is applied to the two sets of piezoelectric elements 32 in the same manner. The output end of the vibration transmitting member 8 is made to perform a linear motion in a direction perpendicular to the shaft. In this case, the vibration state of the output end 8a of the vibration transmission member 8 can be changed by changing the phase of the drive voltage applied to the other electrode plate 38 with respect to the one electrode plate 37. ing. Further, the output end 8a of the vibration transmitting member 8 is in pressure contact with a rotor of an ultrasonic motor 15 formed by a rotating member 13 substantially similar to that of the first embodiment, and is formed on the rotor.
