It is taken out from the inside of the road to the elevator hall through the hole in the bottom of the case (4a). Then, turn the lock nut (7) by hand from the landing side through the connector (9) and the core 1 (sa) to the threaded part (6a) of the wire penetration hardware (6) and screw it in lightly. After that, move one hand from the entrance to the landing to the case (4a).
Hold down the wire penetration hardware (6) by turning it 10 times on the back side, hold the tightening tool holder with your remaining hand, engage its engaging part (12a) with the lock nut (7), and rotate f'L. The agreement will be concluded. At this time, the core wire (8a) Tri, which has been passed through once, and the notch (
121)), so there is no problem with one operation. Furthermore, if there is a small gap around the lock nut (7), it is possible to tighten the lock nut (7), so even if the depth of the case (4a) is difficult to find and the width is narrow, it is possible to tighten the lock nut (7).
The lock nut (7) can be easily tightened.
また、複数の電線貫通金物（６）を近接して取り付ける
場合でも、容易にロックナツト（７）の締結が可能であ
る。Further, even when a plurality of wire-penetrating metal fittings (6) are attached close to each other, the lock nut (7) can be easily fastened.
なお、上記のように一人でロックナツト（７）の締結が
できるので作業時間は大幅に短縮される。Furthermore, since the lock nut (7) can be tightened by one person as described above, the working time is significantly shortened.
上記実施例では締付工具αＸ５は筒状体（１２Ａ）で形
