レンズ鏡筒レンズ位置補正装置。[Scope of Claim for Utility Model Registration] (1) A zoom lens in which a zoom drive lens barrel has a turtle groove and a guide groove that intersect with each other, and a lens holding frame that holds a lens inside the fixed lens barrel is movable in the optical axis direction. In the lens barrel, an eccentric knob is provided by pressing the guide roller that engages with the cam groove and the guide groove, and the lens holding frame is finely adjusted by the eccentricity of the eccentric knob without rotating the guide roller. A lens position correction device for a zoom lens barrel configured to perform image point correction. (2) A notch is formed on the upper surface of the guide roller, and a concave-convex shape is formed on the outer peripheral surface of the eccentric knob so that they fit therein, thereby suppressing slight movement of the guide roller after adjustment. A zoom lens barrel lens position correction device according to claim 1.
