Abstract: A lens hood which is integrated with a lens cover is provided. The lens hood is attached in front of an imaging lens, and is configured to prevent undesired light incident on the imaging lens. The lens hood includes a lens cover having an upper door and a lower door, and a hood body. The hood body supports the upper door and the lower door so as to rotate the upper door and the lower door in opposite directions to each other about an axis orthogonal to an optical axis of the imaging lens, and has a storage space that stores the upper door and the lower door.

Abstract: A lens barrel of this technique includes a movable lens barrel unit section, and a master flange unit having a lens unit, and is switched between a collapsed state where the movable lens barrel unit section is stored in the master flange unit and an extended state where the movable lens barrel unit section is extended from the master flange unit. The master flange unit has a moving frame supported to be movable in an optical axis direction via a first elastic member extendable in the optical axis direction, and a lens frame supported to be movable in the optical axis direction via a second elastic member extendable in the optical axis direction relative to the moving frame. In the collapsed state, the movable lens barrel unit section presses the lens frame such that the moving frame and the lens frame get closer to the master flange against repulsive forces of the first elastic member and the second elastic member.
