发明名称 LENS DRIVING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a lens driving device in which inclination of a lens holding member can be prevented and whose assembling characteristics can be improved. SOLUTION: A lens driving device is provided with a cam ring 20, which is arranged freely turnably at a base 10 and acts as an end face cam in an optical axis direction L, a guide shaft 30 which is extended in the optical axis direction, a lens-holding member 50 which is attached freely slidably to the guide shaft 30 and has a follower pin 53, and an energizing means which energizes the follower pin 53 toward the cam ring 20 in the optical axis direction. The lens driving device adopts a compression spring 60, which is arranged between a front surface of the lens holding member 50 and a cover 70 as the energizing means. Thereby, assemblability can be improved, and the inclination, etc., of the lens-holding member 50 can be prevented.
