Lens module

1 . A lens module, comprising:

a lens barrel configured to accommodate a lens; and

a support member disposed in the lens barrel, and configured to support the lens,

wherein the support member comprises a first support member made of a first material, and a second support member made of a second material that is different from the first material,

wherein the first support member is configured to support the lens, and the second support member is disposed to be spaced apart from the lens and the lens barrel, respectively,

wherein at least a portion of the first support member is configured to be in direct contact with the lens barrel in an optical axis direction, and the second support member is configured to be exposed toward the lens,

wherein a surface of the second support member that is exposed toward the lens is recessed, in the optical axis direction, relative to a surface of the first support member that is in contact with the lens,

wherein the first support member comprises a step disposed on a lens-facing surface thereof, and the second support member is disposed on the step,

wherein at least a portion of inner surfaces of the step extends beyond the second support member and faces each other in a direction perpendicular to the optical axis, and

wherein a rigidity of the second support member is greater than a rigidity of the first support member.

2 . The lens module of claim 1 , wherein the first support member is configured to be in contact with the lens to support the lens.

3 . The lens module of claim 1 , wherein the support member is configured to have a ring shape.

4 . The lens module of claim 1 , wherein a portion of a first surface of the first support member in an optical axis direction, is configured to be in contact with the lens, and at least a portion of a second surface of the first support member in a direction perpendicular to the optical axis, is configured to be in contact with the lens barrel to support the lens.

5 . The lens module of claim 1 , wherein the first surface is a surface at which the first support member and the lens are in contact.

6 . The lens module of claim 5 , wherein the second support member is exposed in the optical axis direction.

7 . The lens module of claim 4 , wherein the portion of the first surface of the first support member in the optical axis direction further comprises a portion that is in contact with the lens barrel.

8 . The lens module of claim 7 ,

wherein the step is positioned between the portion of the first support member that is in contact with the lens, and the portion of the first support member that is in contact with the lens barrel.

9 . The lens module of claim 4 , wherein an empty space is disposed between the second support member and the lens.

10 . The lens module of claim 4 , wherein the support member comprises a plurality of protrusions that extend from the second support member, and are configured to protrude in an outer diameter direction of the first support member.

11 . The lens module of claim 10 , wherein the plurality of protrusions are further configured to protrude further toward the lens barrel than a side surface of the first support member on which the plurality of protrusions are disposed.

12 . The lens module of claim 11 , wherein a side surface of the first support member on which the plurality of protrusions are disposed is a flat surface.

13 . The lens module of claim 10 , wherein the plurality of protrusions are disposed to be spaced apart from each other in a circumferential direction of the second support member.

14 . The lens module of claim 1 , wherein the support member is configured in a form of a pressing ring, comprising a first pressing ring and a second pressing ring.

15 . A lens module, comprising:

a lens;

a lens barrel;

a first pressing ring configured to contact and support the lens; and

a second pressing ring made of a material, different from a material of the first pressing ring, and integral with the first pressing ring,

wherein at least a portion of the first pressing ring is configured to be in direct contact with the lens barrel in an optical axis direction, and the second pressing ring is configured to be exposed toward the lens,

wherein the second pressing ring is disposed to be spaced apart from the lens and the lens barrel, respectively,

wherein a surface of the second pressing ring that is exposed toward the lens is recessed, in the optical axis direction, relative to a surface of the first pressing ring that is in contact with the lens,

wherein the first pressing ring comprises a step disposed on a lens-facing surface thereof, and the second pressing ring is disposed on the step, and

wherein at least a portion of inner surfaces of the step extends beyond the second pressing ring and faces each other in a direction perpendicular to the optical axis.

16 . The lens module of claim 15 , wherein a rigidity of the second pressing ring is greater than a rigidity of the first pressing ring.

17 . The lens module of claim 15 , wherein a plurality of inclined portions are disposed on an inner circumferential surface of the first pressing ring.

18 . The lens module of claim 17 , wherein the plurality of inclined portions are configured to have different inclination angles with respect to an optical axis.
