Abstract
The present embodiment relates to a lens driving device comprising: a fixing member; a housing; a bobbin; an elastic member; and a support member, wherein the support member includes a wire and a member disposed around the wire, and on the basis of an optical axis direction, the member has a length greater than ½ of the length of the bobbin, and the wire protrudes from one end of the member and is coupled to the elastic member, and protrudes from the other end of the member and is coupled to the fixing member.
Claims20
A lens driving device comprising:
- a housing;
- a bobbin disposed in the housing;
- a base spaced apart from the housing;
- a first coil disposed on the bobbin;
- a magnet disposed on the housing and facing the first coil;
- a first substrate disposed on the base and comprising a second coil facing the magnet;
- a first elastic member connecting the bobbin and the housing;
- and
- a support member connecting the first elastic member and the first substrate,
- wherein the support member comprises a wire and a buffer part formed of a material different from the wire and surrounding at least a portion of the wire,
- wherein the buffer part is formed of a different material than the first elastic member,
- wherein the buffer part comprises a groove recessed from an outer circumferential surface of the buffer part, and
- wherein the groove of the buffer part is spaced apart from an upper end and a lower end of the buffer part.
