- a second coil facing the magnet;
- a first elastic member connecting to the bobbin and the second housing;
- and
- a second elastic member connecting to the first housing and the second housing,
- wherein the second coil is spaced apart from the first housing,
- wherein the magnet comprises a first magnet and a second magnet opposite to the first magnet with respect to an optical axis,
- wherein the second coil comprises a first coil portion facing the first magnet and a second coil portion facing the second magnet, and
- wherein a first moving direction of the first magnet by an interaction between the first magnet and the first coil portion of the second coil is different from a second moving direction of the second magnet by an interaction between the second magnet and the second coil portion of the second coil.
A lens driving device comprising:
- a first housing;
- a second housing disposed in the first housing;
- a bobbin disposed in the second housing;
- a first coil disposed on the bobbin;
