摘要：
In a linear-type actuator where an elastic wave is excited upon the vibrator composed of a rod shaped elastic member and a piezo member so as to drive the moving member bought into pressure contact upon the vibrator, the present invention provides a linear-type actuator where the improvement of the driving efficiency and the simplification of the driving circuit can be achieved by the new driving principle.
