PROBLEM TO BE SOLVED: To solve the problem, wherein spacers or the like that differ in thickness are required, when the spacer is interposed, and a plate material is deformed, since the action directions of compression force of compression spring and pressure of an adjusting screw are deviated from each other, when the compression spring is interposed. SOLUTION: After storing the compression spring 16 in a nut 14 attached to a boss 46 with a screw hole 46a and a male screw 46b, a maintenance board 30 of an image device is loaded, the adjusting screw 12 is inserted into the compression spring 16 to be attached to the boss from the upside of the maintenance board and tightened, until the maintenance board contacts the nut. The nut 14 is let out from the maintenance board 30 to make the holding plate into a floating state, the adjusting screw 12 is tightened against elastic force of the compression spring 16, its tightening state is adjusted and the position of the maintenance board 30 to a mirror box 40 is adjusted. The nut 14 is returned, tightened, until it contacts the maintenance board 30, and the maintenance board after adjustment is held and fixed between the nut and a head 12a of the adjusting screw.
