ま次工程に移行する怖れがあった。However, in the above conventional example, in order to set both anchor pieces 32/33 to a right-angle cross in the step shown in FIG. While holding the washer 36 with one hand, the connecting string 35 is appropriately pulled with the other hand, and the tension of the string causes the two anchor pieces 32/33 to move from the overlapping state in FIG.
In this case, it is rotated in the shape of an orthogonal cross as shown in the figure, but in this case, the state is closed by the washer 36 and it is difficult to see, so that the operability is poor and the first important function as this kind of anchor function. It was not possible to confirm the orthogonal cross-shaped arrangement, and there was a fear that the process would proceed to the next step without being sure.
