軸微動装置。[Claims for Utility Model Registration] The rotation of the holder part is finely adjusted by tightening a rotating shaft that allows the holder part to rotate freely with respect to the base part via a tensioning frame, and making slight movements. In the rotating shaft fine movement device, an outer cylinder is inserted and fixed to the holder portion with its end protruding, a collar portion is formed on the outer circumferential surface, and a female screw portion is formed on the inner circumferential surface, and the outer cylinder is inserted into the outer cylinder, an intermediate hollow shaft body fixed with screws in the axial direction of the outer cylinder with the flange abutting the end part; and rotatably mounted inside the outer cylinder outside the intermediate hollow shaft body, A tensioning hollow shaft body has a tensioning operation knob fixed to one end thereof, and a male threaded part is formed to be screwed into the female threaded part to slightly rotate the holder part inside the intermediate hollow shaft body. 1. A rotating shaft fine adjustment device comprising a fine adjustment shaft body which is mounted so as to be movable forward and backward, and has a fine adjustment operation knob fixed coaxially with the tightening operation knob at one end thereof.
