Abstract

PURPOSE:To bend a work to a precise bent angle by turning a 2nd and a 3rd turning member with an operating device. CONSTITUTION:In a 1st oscillatory rotation mechanism part 4, a 1st turning member 40 is turned by the operation of a driving motor 44 a desired angle round the axis of a member X to be worked. Second and 3rd turning members 50, 60 are turned entirely with this turning and torsional bending of the axis is performed to the member X to be worked. When a motor 56 is actuated in the 2nd oscillatory rotation mechanism part 5, the 2nd turning member 50 is turned by a desired angle in the clockwise or in the couterclockwise direction. Since the 3rd turning member 60, too, is turned, the axial direction of the member X to be worked can be bent by a bending member of the 3rd turning member 60 to the right or to the left. Further, in the 3rd oscillatory rotation mechanism, the 3rd turning member 60 only is turned by the operation of a driving motor 63 a desired angle round the axis 61 upward or downward. The member X to be worked engaged to the engaging part with this turning can be bent forcedly upward or downward.
