<p>A lens driving device is provided with a base (10); a lens frame (40); a nut (70) which screws together with a lead screw (60) and moves with the lens frame (40); a main guide shaft (31) which guides the lens frame (40) in an optical axis direction; a sub-guide shaft (32) which guides the lens frame (40) in the optical axis direction while regulating rotation of the lens frame (40); and a cover (20) arranged to face the base (10) for fixing the main guide shaft and the sub-guide shaft by having them fit in the cover. The lens frame (40) is provided with a lens holding section (42) protruding to the outer side of the base and the cover. The base (10) and the cover (20) are provided with a first positioning pin (23a) and a first positioning hole (12a), which are arranged at the vicinity of the main guide shaft (31), and a second positioning pin (23b) and a second positioning hole (12b), which are arranged at positions separated from the main guide shaft (31).Thus, the lens driving device which can be highly accurately assembled and has high optical performance can be obtained.</p> |
