Abstract
In a lens barrel for use in a camera, the inner wall of a fixed barrel and the outer wall of a rotatable barrel are shaped in a first helicoid engagement and the inner wall of the rotatable barrel and the outer wall of a lens holding-barrel are shaped in a second helicoid engagement, wherein a pitch of the second helicoid engagement is substantially equal to that of the first helicoid engagement. One end of a flexible print circuit is connected with an electrical device on the lens holding-barrel, the middle portion of it is extended backward between the outer wall of the lens holding-barrel and the inner wall of the rotatable barrel and is turned around the back end of the rotatable barrel so as to be further extended forward between the outer wall of the rotatable barrel and the inner wall of the fixed barrel, and the other end of it is passed a through hole provided on the fixed barrel and is extended to the camera body.
