<P>PROBLEM TO BE SOLVED: To provide a lens moving device which has increased moving displacement of a lens and minimizes the loss of power transmission to increase driving efficiency. <P>SOLUTION: A lens moving device includes a lens receiving part with at least a lens disposed therein, having first and second extension parts formed at opposed sides in a predetermined interval from each other. The lens moving device also includes an actuator configured so that a body which has first and second output members contacting the first and second extension parts of the lens receiving part at opposed ends thereof, and thereby expands, contracts and bends when power is applied, is arranged between the first and second extension parts to provide a moving force required for the transfer of the lens receiving part. The lens moving device also includes a preload member provided in the upper part of the actuator, so that the preload member compresses the first and second extension parts against the actuator body to maintain the status of pressed contact between the first and second extension parts and the first and second output members. The moving device further includes a guide part for guiding the movement of the lens receiving part in an optical axis direction. <P>COPYRIGHT: (C)2007,JPO&INPIT |
