Abstract
A lens barrel includes a first holding member configured to hold a lens, a second holding member configured to hold the first holding member, a protection member located at an object side of the lens in an openable and closable manner and configured to protect the lens when in a closed state, and a drive member configured to open and close the protection member. The first holding member includes an adjustment surface configured to support the first holding member rotatable with respect to the second holding member around a point located on an optical axis of the lens. The drive member is located such that the drive member overlaps the first holding member as viewed from an optical axis direction of the lens.
