ABSTRACT:
A lens driving device is provided to reduce a number of required high-accuracy components and also eliminate the unevenness of maximum displacement of a lens holder with respect to a base. An outer edge of a lower spring plate is clamped by a lower casing served as a base and a lower spacer. A first protrusion is formed on a sidewall of the lens holder and protruding outward therefrom. A second protrusion protruding toward the lens holder is formed on an inner circumference of the lower spacer and extends to a position above and separating from the first protrusion by a distance S. The first protrusion props against the second protrusion when the lens holder is moved toward an imaged-object side and reaching a displacement of the distance S.
