<P>PROBLEM TO BE SOLVED: To provide a zoom lens barrel which eliminates the necessity of preparing a plurality of adjustment members corresponding to the amount of inclination shift to be adjusted of a movable lens and is capable of continuously adjusting the amount of inclination shift of the movable lens. <P>SOLUTION: The zoom lens barrel guiding a movable lens group displaced on an optical axis by zooming by a guide pole, to move the movable lens group on the optical axis includes: a fixed frame member; an adjusting frame member indirectly supporting a shift-adjusted movable lens; the guide pole planted in the adjusting frame member in parallel with the optical axis; adjustment coupling means coupling the fixed frame member and the adjusting frame member, so as to adjust an interval between the fixed frame member and the adjusting frame member by interposing a compression elastic member at least at three places at the center of the optical axis; and a movable lens frame member supporting the shift-adjusted movable lens and sliding on the guide pole. <P>COPYRIGHT: (C)2013,JPO&INPIT |
