PROBLEM TO BE SOLVED: To enhance working efficiency and to make the mirror surface of an antenna highly accurate. SOLUTION: A mount structure 3 to mount a reflecting mirror 2 is interposed between a support structure 1 to support the reflecting mirror 2 and the reflecting mirror 2 itself. The mount structure 3 has a screw shaft 7 supported by the support structure 1, an adjustment nut 8 screwed to the screw shaft 7, a support 9 having a supported face 13 that is a face of the adjustment nut 8 and that is supported by an orthogonal face 12 at a right angle to the shaft to support the reflecting mirror 2, and a fixing nut 11 that is screwed with the screw shaft 7 to fix the support 9 while clamping the support 9 between the adjustment nut 8 and the nut 11. The adjustment nut 8 has polygonal circumferential faces around the screw shaft 7. A hex wrench is used to tighten both the nuts to assemble each mirror surface element by adjusting and fixing each freely at an optional height in a direction of normal. Thus, the working efficiency can be enhanced with high precision. Provision of a scale marking is preferred.
