Abstract
A lens barrel includes a rectilinear unit, a lens unit, and a light shielding member. The lens unit is arranged inside the rectilinear unit and is movable relative to the rectilinear unit in an optical axis direction. The light shielding member functions for light shielding between the rectilinear unit and the lens unit. The light shielding unit has a light shielding layer and a support layer. The shielding layer is fitted on a decoration frame of the lens unit and closes a gap defined between the rectilinear unit and the lens unit and extending in the optical axis direction. The support layer has a body bonded to the light shielding area. The body has at least one low rigidity portion. The low rigidity portion has rigidity lower than that of the body.
Claims14
A lens barrel comprising:
- a first barrel portion;
- a second barrel portion which is arranged inside the first barrel portion and is movable in an optical axis direction relative to the first barrel portion;
- and
- a light shielding member for light shielding between the first barrel portion and the second barrel portion,
- wherein the light shielding member comprises:
- a light shielding layer with an endless ring shape which is slidably fitted on the second barrel portion and closes a gap defined between the first barrel portion and the second barrel portion and extending in a direction orthogonal to the optical axis direction;
- and
- a support layer including a body with endless-ring shape bonded to the light shielding layer and at least one low rigidity portion having rigidity lower than that of the body.
