PROBLEM TO BE SOLVED: To provide a bending correcting device for a bend blade of a bending press for metal plates with which the correction of the error of blade parallelism to an upper die and lower die is automatically executed and, moreover, because the mode of the generation of the error of every classes of products is preserved as numerical data, the generation of accidental error is dealed with properly and quickly in the bending press for metal plates where link mechanisms to which horizontal links and vertical links which are moved with crank mechanisms are pivotally attached are parallely disposed concerning the driving device for the bend blade. SOLUTION: About at least one of horizontal links 9 provided in parallel, the eccentric shaft 18 of the crank mechanism constituting the driving device is pivotally supported to that horizontal link 9 through an eccentric bearing 25, a servomotor 29 for turning the eccentric ring 27 of the eccentric bearing 25 bit by bit is attached to the horizontal link 9, which is finely adjustable forward and backward by turning the eccentric ring 27.
