PURPOSE:To obtain a large amount of displacement with less driving energy, by aligning one-axial type actuating members and non-actuating members in the direction approximately perpendicular to the axial direction of the actuating members, linking the neighboring members at one end of each member, and avoiding the continuation of the linking parts of the members at the same end of each member. CONSTITUTION:A voltage is applied between lead wires 8 at both ends from the outside. Then the voltage is applied to all conductors 4 for external electrodes through conductors forming grade separation at the upper surface of linking members 7. The actuator comprising an individual piezoelectric element 1 is expanded (contracted) in correspondence with the value of the voltage Va. Therefore, the amounts of displacements in the actuator apparatus are added from one end to the other end. Then, the amount of displacement at the end part at the time of the voltage Va becomes md, where (d) is the amount of displacement of the individual actuator, and (m) is the number of the actuators. |
