PURPOSE:To diminish change of dies and improve work efficiency by constituting one of a pair of dies of a platelike member that can come into contact with an elastic bent member and a pushing member that pushes the platelike member against another die. CONSTITUTION:When bending the member 7 to be bent, the member 7 is placed between the platelike member 6 and a lower die 2, and an upper surface plate 3 is lowered. Pushing members 5a, 5b go down and come into contact with the platelike member 6 and bend the platelike member 6 and member 7 to be bent. To change the size of bending circular arc of the member 7 to be bent, a lower die is changed. As the size of circular arc of the member to be bent 7 is determined by the curved face of the lower die 2, bending can be performed at high accuracy even if adjustment of distance between supporting points of pushing members 5a, 5b is rough. |
