Abstract
The lens barrel includes a lens housing barrel including a first barrel portion and a second barrel portion having a diameter smaller than that of the first barrel portion, an external barrel disposed at an outer circumference of the lens housing barrel and extending from an object side further than the first barrel portion to the second barrel portion, and a first elastic member disposed between the external barrel and the second barrel portion and elastically deformable with a movement of the external barrel with respect to the lens housing barrel due to an external force from the object side. The lens barrel further includes a second elastic member disposed between the external barrel and the first barrel portion and elastically deformable with a movement of the external barrel with respect to the lens housing barrel due to an external force from a radially outer side.
