Abstract
A lens barrel assembly includes a lens barrel and a lens hood detachably mounted on the lens barrel. A lens barrel includes a mounting threaded portion and three guide rails at three circularly equally spaced positions around the lens barrel. Each guide rail is provided with a forward latch and a rearward latch. The lens hood is constructed of an elastically deformable member, and has a notch to be engaged with the rail. The lens hood is in sliding engagement with the outer circumference of the lens barrel, and is movable between a retracted position and a photographing position. At each position, the lens hood is locked by the respective latch. The lens hood is easily shifted to the photographing position or to the retracted position along the lens barrel, and is also easily attached to and detached from a camera.
