Abstract:
The bending device 25 comprises a positioning jig 10 having a clearance opening 8 formed therein for passing an elongate material 1, fixed to a device body, and a movable bending jig 28 having a clearance opening 30 formed therein for passing the material 1, provided at a position to which the material 1 is supplied from the positioning jig 10. The bending jig 28 is attached to a dome portion 26 which is part of a rotating member 24 rotated along a spherical surface having the center on the material 1 passing through the positioning jig 10.
