<p>The camera lens barrel (2,3) includes a driving power source (20), a set of lenses (6,12,7,14) mounted in the barrel and a number of reference shafts (10,11) extending parallel to an optical axis. At least one of the reference shafts (10) is provided with a threaded portion (10a) and used as a rotating shaft of the driving power source. Detent means (17) are also provided for preventing deflection of a body of the driving power source, so that the lens moves to and fro along the threaded portion upon activation of the driving power source. <IMAGE></p> |
