PURPOSE:To facilitate the position adjustment in three axial directions, by planting screw bar in a supporting device fitted to a reflective mirror frame and supporting a unit mirror panel of the reflective mirror by a spherical screw tool inserted to this screw bar. CONSTITUTION:Upper and lower subplates 5 and 6 where screw taps are provided in center parts, a supporting bar 3a to be screwed to these subplates 5 and 6, and a check nut 8 are assembled under the state of rough setting of a vertical direction Y, and this assembled material is adjusted in a radius direction Z as well as a circumferential direction X between a supporting base 4 and a unit mirror panel 2, and the lower subplate 5 is fixed to the supporting base 4 by a bolt set 9. Next, respective inside-and-outside screw cylindrical materials 13 are rotated individually to be moved in the direction Y of the screw axis between the upper subplate 6 and the unit mirror panel 2, thus adjusting the supporting device finely. Thereafter, locking washers 14 for inside-and-outside screw cylindrical materials 13 are set, and the upper subplate 6 is fixed by inside screw parts of inside-and-outside screw cylindrical materials 13 and a bolt set 10, thus fixing the unit mirror panel 2 indirectly. |
