| 摘要 |
This ultrasonically-actuated unit is provided with: an ultrasonic wave transmission unit that is provided along the lengthwise axis and transmits ultrasonic vibrations; a relay unit that, at a node position of longitudinal vibrations, is contiguous with the ultrasonic wave transmission unit or is connected to the ultrasonic wave transmission unit; and a non-contact vibration unit that can transmit improper vibrations, is provided along a direction parallel to the lengthwise axis in the state of not contacting the ultrasonic wave transmission unit, and to which improper vibrations are transmitted from the ultrasonic wave transmission unit via the relay unit. The ultrasonically-actuated unit is provided with a vibration absorbing unit that absorbs the improper vibrations transmitted to the non-contact vibration section. |
