PROBLEM TO BE SOLVED: To provide a bender auxiliary tool which measures a flexure degree while bending a rod-like article and can achieve a target flexure degree.SOLUTION: A bender auxiliary tool which is used while being attached to a hand-operated bender which comprises a bar, a bending part at a tip of the bar, and an engagement part above the bending part, and which inserts a rod-like article into between the bending part and the engagement part and bends the rod-like article by utilization of a principle of leverage. The bender auxiliary tool comprises: an installation part which is installed to the rod-like article; an expansion part which is projected from the installation part; a rail part which stands up from the expansion part; a slide bar which moves the rail part following bending of the rod-like article while contacting the rod-like article; and a measure which is attached to the rail part and measures a movement distance by bending of the rod-like article corresponding to a bending angle of the rod-like article.SELECTED DRAWING: Figure 1 |
