The outer cylinder 2 and the columner body 3 are mutually in an eccentric relation with an eccentric distance (l) and a space 4 having the minimum clearance 4a and the maximum clearance 4b is provided. This clearance 4 becomes a passage for the circular pipe (p) having a mean outer diameter (d) to be corrected. The relations between (l1), R1, R2, (d) are as follows, d=(R1-R2-l)X1/(1-alpha), where alpha is a rate of deformation and its value is 0.005-0.03. Either of the outer cylinder 2 and the columner body 3 is freely rotatable and is connected to a driving source. The width of the minimum clearance part 4a to give the maximum deformation value is regulated its eccentric distance (l) so as to become narrower by alphad than the mean outer diameter of the circular pipe (p). In this way, the accurate correction working is performed.
