に相互芯の確認ができるようになる。In FIGS. 1 and 2, the light projecting section 4 has been used so far.
The light rays radiated from the a to the light receiving portion 4b facing each other were invisible light rays, and the lower end and 1500 mm above the lower end are visible light rays 6a and 6b. According to the present invention, the visible light rays 6a and 6b are defined at the two positions, and the visible light rays 6a and 6b emitted from the light projecting portion are placed at the center of the mark marked on the light receiving portion as shown in FIG. Since the mutual cores of the light beams can be aligned with each other by adjusting the parts, the adjustment work is facilitated, and the mutual cores can be easily confirmed during the inspection work.

に当たる下端と本来なら上端とすべきだが、現状の安全
装置上端部は１８００ｍｍと高い位置となり調整作業と
確認作業がしづらいと判断し、確認し易い１５００ｍｍ
の位置とした。The reason for setting the positions of the visible rays 6a and 6b to the lower end and the position of 1500 mm from the lower end is that the lower end which is the foot of the passenger and the upper end should be the upper end, but the upper end of the current safety device is as high as 1800 mm. It is judged that it is difficult to perform the adjustment work and the confirmation work, and it is easy to confirm 1500 mm
