ABSTRACT:
A lens actuating device moves a movable lens held by a lens holder in predetermined directions. The lens actuating device has a power transmitting shaft connected to the lens holder for movement in axial directions thereof, and a fluid case having a shaft support sleeve and filled with a working fluid, the power transmitting shaft being axially slidably supported in the shaft support sleeve. The fluid case includes a piezoelectric device as a portion thereof. When a drive voltage is applied to the piezoelectric device, the piezoelectric device can be deformed to displace the working fluid in the fluid case to move the power transmitting shaft axially, thereby moving the lens holder and the movable lens in the predetermined directions.
