Abstract
The present invention provides a lens driving device having a component for limiting a movement amount generated during impacting, wherein an impact force is alleviated by utilizing the component for limiting the movement amount, so that a driving coil can be prevented from falling off, and the damage to the leaf springs can be alleviated. The leaf springs formed into a cantilever beam structure as the damper for alleviating the impact in the vertical direction and the planar direction are arranged between the lower fixing body and the upper fixing body, and the impact force can be alleviated by utilizing first projection parts and second projection parts projected out from the lens support, and the existing structure does not need to be greatly changed.
