Abstract

A curvature retaining device () includes two support points () that can abut against one surface of a plate-shaped workpiece W, one or more pressing points () that can abut against a position of the other surface of the plate-shaped workpiece (W) between the support points (), and forward/backward drive means (support unit () and pressing unit ()) for moving at least either the support points () or the pressing points () forward to and backward from the other. Preferably, the two support points () abut against the one surface of the plate-shaped workpiece (W) at a first distance (Ls), the two pressing points () abut against the other surface of the plate-shaped workpiece (W) at second distance (Lp) shorter than the first distance (Ls), and a middle point of the first distance (Ls) and a middle point of the second distance (Lp) match with each other.
