Zusammenfassung: | The present invention provides a lens driving device for reducing inclination angle of a lens during shooting. In the lens driving device of this invention, a front spring (22) and a rear spring (24) disposed respectively at the front and rear sides of the optical axis (O) of a lens holder (14), each comprises: inner peripheral ends (222, 242) installed on the lens holder (14); outer peripheral ends (224, 244) installed on the fixing parts (12, 18, 20, 28); and two arms (226, 246) connecting the inner peripheral ends and the outer peripheral ends. The direction having a maximal spring coefficient among the circumferential directions of the plane where the front spring (22) and the optical axis (O) are orthogonal and the direction having a maximal spring coefficient among the circumferential directions of the plane where the rear spring (24) and the optical axis (O) are orthogonal have an included angle less than 45 degrees. |
