ABSTRACT:
A lens driving mechanism for moving a lens in its optical axis direction has a lens frame for holding the lens, guide means for guiding the lens frame to be movable in the optical axis direction of the lens, and an actuator having an actuation portion that moves in a direction nearly parallel to the optical axis of the lens. In the lens driving mechanism, the lens frame and the actuation portion are directly or indirectly connected so that the lens frame does not move in the optical axis direction relative to the actuation portion of the actuator.
