PURPOSE: To provide a surface shape adjusting system capable of efficient adjustment of a surface shape.

CONSTITUTION: A moving adjustment body 10 is provided which is moved between plural pole brace bodies 8 supporting a parabolic antenna 2 while successively grasping them and moves error adjusting parts 9 attached to a parabolic antenna 2 of pole brace bodies 8. The moving adjustment body 10 is moved to the pole brace body 8 in the part, where an antenna surface 3 of the parabolic antenna 2 has not a prescribed surface shape, while successively grasping adjacent pole brace bodies 8 and moves the error adjusting part 9 of this pole brace body 8 forward or backward to give the antenna surface 3 of the parabolic antenna 2 the prescribed surface shape. Thus, the surface shape is efficiently adjusted by the simple and light-weight constitution.
