More than, according to present embodiment, the position of the short transverse Z (arrow A 1, A2 direction) of the axis of guide 14 and Width X (arrow B 1, B2) can be adjusted respectively independently, but and precision adjust optical axis L 2 well.
And in the present embodiment, as above-mentioned, by the rear side that is pressed in axis G direction, perhaps the front end components 44 of being suppressed in the front side of axis G direction by ring spring 43 is moved in the mode that is directed to dip plane S, and moves to short transverse Z by screw 51.On the other hand,, perhaps moved to Width X by the front end components 44 that is pressed in arrow B 2 directions by being pressed in arrow B 1 direction by screw 52 by laminated spring 55.Thereby, can most desirably bring into play the short transverse Z of the axis of guide 14 and the position of Width X are distinguished the above-mentioned action effect of adjusting independently.
And then, as above-mentioned, because screw 51 is screwed together in the body 5 of shell 4 in axis G direction, and, screw 52 is screwed together in the body 5 of shell 4 at Width X, therefore, reduced on the formation of the short transverse Z in the shell 4 restriction (for example, be used to guarantee that the screw that screw 51,52 is screwed togather is grown etc.), can realize the slimming of shell 4.
In addition, in the present embodiment, as above-mentioned, the axis of guide 14 has front end components 44, is formed with dip plane S1 in its front end components 44.Thus, and when axis body 41 directly forms dip plane S1, compare, can fully guarantee the area of dip plane S.
In addition, in the present embodiment,,, therefore, can guide moving of front end components 44 energetically with dip plane S because the face 44d of front end components 44 is pushed along short transverse Z by laminated spring 55 as above-mentioned.
In addition, in the lens barrel 2 of present embodiment, the optical axis that is constituted as the optical system by adjusting shutter Zoom lens unit 12 can easily be adjusted the optical axis L 2 of optical axis L 2.That is the axis of guide 14 guiding moving, to the highest optical system of the contribution degree of the adjustment of optical axis L 2.In addition, in lens barrel 2, body 5 is formed by resin, and the dimensional tolerence of the base end part 41a of the recess 42 of body 5 and axis body 41 becomes chimeric (chimeric) tolerance, has suppressed the negative effect of fascinating optical axis being adjusted of the axis of guide 14.
More than, ring spring 43 constitutes the 1st and suppresses member, and the face 44c with front end components 44 in the laminated spring 55 suppresses part at Width X and constitutes the 2nd and suppress member.
