Abstract
A lens barrel unit for a zoom lens camera which is more compact in the axial optical direction in the retracted state because the lens group moving means and linear movement guiding means are juxtaposed along the optical axis. The lens barrel unit also has a reduced outer diameter due to a reduction in the need for a separate outer helicoid portion of the moving means and elimination of guiding grooves on the inside of the fixed barrel unit.
