Abstract:
An actuator which drives a lens frame in an optical axis direction is constructed by piezoelectric elements, driving members, and a pressing spring. The piezoelectric elements are placed at opposite sides with a driven plate therebetween, and the driving members are fixed to the respective piezoelectric elements. The driving members are pressed against the driven plate from both sides by the pressing spring.
