PROBLEM TO BE SOLVED: To provide a lens driving device capable of preventing the change of motor characteristics and smoothly moving a carrier in the optical axis direction of a lens by preventing the deformation of a spring due to the shift in the horizontal direction and backlash of the carrier.SOLUTION: The lens driving device 1 moves the carrier 7 in the optical axis direction of the lens by an electromagnetic force generated by the energization of a coil 10. The spring 11 is an annular leaf spring in plan view and includes an inner ring 11a attached to the side of the carrier and an outer ring 11b attached to the side of an outer barrel part 5. The carrier 7 has a positioning part 23 provided to project outward in a radial direction and the outside edge 23a of the positioning part 23 is located to face the inner circumference of the outer ring 11b of the spring 11, to perform positioning between the carrier 7 and the outer barrel part 5. |
