PROBLEM TO BE SOLVED: To provide a super-fine adjustment apparatus for an optical apparatus capable of performing fine focusing adjustment and having load bearing characteristics, while holding an imaging apparatus. SOLUTION: A clamping screw 30 having a ball with its part made a flat surface, and a spring 17 are arranged on a wall surface 18 being the surface of a first unit 10 facing a second unit 20. The second unit 20 includes a fine focus adjustment handle 21 which is operated so as to finely move the first unit 10, and a fine moving screw shaft 22 connected to the handle 21 and arranged along the wall surface part 27. Further, a fine movement lever 40 is rotatably fixed along the wall surface part 27 by taking a fulcrum shaft as a center. When a flange part 23 is moved in a left direction in Fig. by rotating the handle 21, a projection part 44 is pressed by the flange part 23, then, the lever 40 is rotated by taking the fulcrum shaft 48 as the center, and the end face 43 of the lever 40 goes upward in the fine movement direction. Thus, as a fine movement spring bearing 16 goes upward, the first unit 10 goes upward. COPYRIGHT: (C)2007,JPO&INPIT
