    • An elastic member 43 comprises a crystalline resin. The elastic member is fixed to a piezoelectric element 42 that generates vibration in response to application of an AC voltage, is in contact with a movable body 45 in use, and flexurally vibrates in response to the vibration of the piezoelectric element 42 to drive the movable body 45. The elastic member 43 may have a tooth 43b on an opposite side with respect to a side fixed to the piezoelectric element 42. The crystalline resin may be a poly(aryl ketone) resin or a poly(phenylene sulfide) resin. The piezoelectric actuator has an excellent transmission of flexural vibration. In a case where a displacement expansion element of a displacement-expanding piezoelectric actuator is formed from a crystalline resin, the actuator greatly amplifies an expansion and contraction displacement of a piezoelectric element. In a case where a resonance member of a Langevin transducer is formed from a crystalline resin, the transducer allows the vibration of the surface at a high speed even in application of a low electric current (or a low voltage).
    • 弹性构件43包括结晶树脂。 弹性构件被固定到压电元件42上,该压电元件42响应于施加交流电压而产生振动,与使用中的可移动体45接触,并且响应于压电元件42的振动而弯曲地振动以驱动可动 弹性构件43可以在相对于固定到压电元件42的一侧的相对侧上具有齿43b。结晶树脂可以是聚(芳基酮)树脂或聚(苯硫醚)树脂。 压电致动器具有优异的弯曲振动传递。 在位移膨胀型压电致动器的位移膨胀元件由结晶树脂形成的情况下,致动器极大地放大压电元件的膨胀和收缩位移。 在Langevin换能器的共振构件由结晶树脂形成的情况下,即使施加低电流(或低电压),换能器也可以高速地振动表面。
