    • In a truss type actuator having two piezoelectric devices provided for crossing at right angle and driven by two alternating driving signals having a predetermined phase difference between them for driving a chip member along a predetermined elliptic trail (including a circular trail). The piezoelectric devices are contacted by protrusions having a high rigidity and formed on contacting faces of the chip member and a base member for holding the piezoelectric devices, and fixed by adhesive having a low rigidity and filled around the protrusions. Thereby, one of the piezoelectric device hardly receives a reaction force from another piezoelectric device due to the displacement thereof.
    • 在具有两个压电装置的桁架式致动器中,该压电装置被设置为以直角交叉并由它们之间具有预定相位差的两个交替驱动信号驱动,用于沿预定的椭圆迹线(包括圆形迹线)驱动芯片部件。 压电元件与具有高刚度的突起接触,并形成在芯片部件和用于保持压电元件的基底部件的接触面上,并且通过具有低刚性并填充在突出部周围的粘合剂固定。 因此,压电装置中的一个由于其位移几乎不会受到来自另一个压电装置的反作用力。
