Abstract
An exemplary lens barrel includes an accommodating member having a cylinder, a lens barrel, a holder for fixing the accommodating member, and a resilient member. The cylinder has a plurality of stepwise slits each having an end exposed at an underside surface thereof. The lens barrel has a plurality of restricting elements extending from an outer surface thereof. The lens barrel is coaxially accommodated in the cylinder with the restricting element passing through a corresponding slit. The resilient member is sandwiched between the lens barrel and the holder, capable of changing its length under an external force, such that a focal length of the lens module is adjustable when the restricting elements move in and along the slits.
