−前記折曲部７αの頚部が損傷する事態も生じる。For this reason, as shown in FIG. 5, in order to cope with the above-mentioned load, a pipe 7' is attached to the wire 7, which is bent and stored and fixed in the storage part 9' of the sleeve 9. When releasing the forceps 5.5, that is, the forceps 1
When the wire 7 and the bent portion 7α of the pipe 7' are moved forward through the operating bush 4' or the operating cylinder 4', there is a risk that the bent portion 7α of the wire 7 and the pipe 7' may separate from the sleeve 9 (the force at this time is 1 y). In addition, if the opening/closing operation of the forceps 5.5, that is, the forward/backward movement of the sleeve 9 is carried out in a summer manner, the neck of the bent portion 7α may be damaged.
従って、スリーブ９９収納部９′に折曲部７ａを収納後
、ハンダ１３で固着しているのが常態である。Therefore, after the bent portion 7a is stored in the sleeve 99 storage portion 9', it is normally fixed with the solder 13.

点がある。According to this conventional example, a high degree of skill is required to form the bent portion 7α and to store the sleeve 9, and the “bent portion 7α
A pipe 7' is required to strengthen the neck of the 1.
There is a problem in that productivity is low because it involves fixing work according to step 3.
