難しくしており、この点でもまた熟練を要する。 When both ends of the linear body 4 are grabbed and bent using radio pliers, it is difficult to bend the linear body into a specified shape, and the inner diameter R1 is set to a desired value. It requires special skill. In addition, bending force and gripping force are required during processing, making processing difficult, and skill is also required in this respect.

弧状になる。 Then, grasp the operating members 10 and 11 with both hands and bend them so that they are parallel to each other as shown in FIG. As a result, the linear body 4
It is curved into a circular arc within one plane passing through the first axis.
At this time, the peripheral edges 12a and 18a of the end portions 12 and 18 of the operating members 10 and 11 come into contact. Then, the operating members 10, 11 are further displaced in the approaching direction as indicated by reference numerals 24, 25. As a result, the edge 12b of the one end portion 12, 18 of the operating member 10, 11,
With 18b as a fulcrum, the ends 1 of the operating parts 14 and 20
4a and 20a are displaced until they come into contact. In this way, the curved arc shape of the linear body 4 is prevented from returning, and an accurate semicircular arc portion is formed by plastic deformation. Since the portion of the linear body 4 that is fixed by the guide holes 17 and 22 remains constant during the bending operation, the portion l3 that is bent, that is, the portion l3 that receives the force, does not change at all times. Therefore,
A uniform force is applied to the bendable portion l3 of the linear body 4 as a whole, and the linear body 4 is deformed so that the curvature of the linear body 4 is constant in all parts. Therefore, the linear body 4 has a semicircular arc shape.
上述の実施例では凹所１６，２１は円錐形であ

ることがわかる。 The experimental results of the inventor of the present invention will be described. The linear body whose cross section is shown in FIG. 1 has an outer diameter of 2.25 mm.
Reference mark R2 in the figure is 7.75 mm, and the bending work was performed by two beginners. Each worker performed bending work on a total of 10 linear bodies. As a result of this work, the curved linear body has an inner diameter of 13 mm and an outer diameter of 15 mm.
It was evaluated whether it fit within the inspection area of a semicircular arc. As a result, out of a total of 20 curved linear bodies, 18 fell within the inspection area, and only 2 fell outside the inspection area. The time required for bending each linear body was approximately 5 seconds. This shows that it is possible to bend a large amount of linear bodies into semicircular arc shapes with high precision.
