ABSTRACT:
A lens barrel unit with a lens barrier highly resistant to infiltration of external dirt, dust, and water has a pair of blade members each pivotally movable about a barrier joint hole. Engaging shafts connect to the blade members. The engaging shafts extend coaxially with the barrier joint holes about which the blade members pivotally move. A barrier driving ring applies a driving force to each engaging shafts to rotate it about the corresponding barrier joint hole. The lens barrel has a pair of through holes through which the engaging shafts are rotatably inserted. The engaging shafts are driven for rotation by the driving force transmitted to hook parts of the rotary shaft. The blade members are pivotally movable in the optical axis direction. The lens barrel also serves as a barrier base plate and is disposed between the blade members and the barrier driving ring.
