Abstract
The present invention provides a lens driving device includes at least two spring components each of which includes an inner side retaining part, an outer side retaining part, a plurality of wrist parts configured between the inner and outer side retaining parts and prolonged along the circumference direction, inner side connecting parts for connecting one ends of the wrist parts with the inner side connecting part, and outer side connecting parts for connecting the other ends of the wrist parts with the outer side retaining part. Moreover, serpentine necking parts are formed at the roots of the connecting part of the inner side retaining part, straight line-shaped necking parts are formed at the roots of the connecting part of the outer side retaining part, so that stresses acting on the inner side connecting parts and the outer side connecting parts during assembling are absorbed.
