範囲第１項記載のズームレンズの絞り補正装置。[Scope of Claim for Utility Model Registration] 1. A zoom lens that changes the aperture diameter in response to zooming to compensate for fluctuations in the aperture value due to zooming, which is rotatable around the optical axis; The aperture part is held in the lens barrel without being able to move in the axial direction, and the aperture diameter is changed by rotating the aperture part around the optical axis in response to the movement of the variable magnification moving body in the optical axis direction. and an interlocking mechanism that connects the variable magnification moving body and the aperture section so as to
The interlocking mechanism is a zoom lens aperture correction device that can adjust the tilt with respect to the optical axis during assembly adjustment. 2. The aperture correction device for a zoom lens according to claim 1, wherein the interlocking device is provided so that its inclination with respect to the mounting member 7 can be adjusted using two adjusting screws.
