PROBLEM TO BE SOLVED: To provide an unevenness correcting apparatus which enables unevenness to be easily and rapidly corrected, even if a great load is imposed on a plumbing column. SOLUTION: In this unevenness correcting apparatus 10, when a force F1 is imparted to one end (a point of a lever) of an arm 20 from a hydraulic cylinder device 24 as "a pressing means", the arm 20 is turned around an action shaft (a point of action) 22, and a fulcrum part 40 is pressed against a side surface of the plumbing column 14 so as to serve as "a fulcrum". Thus, a force F2 acting in the same direction as the force F1 is imparted to a second erection piece 18 from the action shaft 22 as "the point of action", and the plumbing column 14 is displaced by the force F2.
