Abstract: A movable die base (2) is moved toward a stationary die base (1). A pressing force is applied by a bending punch (21) disposed on the movable die base to a bending target portion of a pipe (A) which is placed on a die (11) provided on the stationary die base and which has inserted therein a core metal (17). At the time of this bending work, both ends of the pipe are restricted by holding them with restriction pads (22). When the pressing force is applied by the bending punch, the restriction pads are displaced to follow the pressing of the bending punch, whereby restricted state on both ends of the pipe is constantly maintained.
