挿入しやすくしている。3 to 7 are explanatory views of how to use the opening degree limiting jig 32 of this embodiment. When the operator manually opens the hall door 24, first, the opening degree limiting arm 40 is oriented in a direction substantially orthogonal to the contact plate 34 as shown in FIGS. 3 and 4. This holds the backing plate 34 and holds the handle 44.
It can be easily done by twisting. And the backing plate 34
Is brought into contact with the surface of the hall door 24 on the elevator hall side, and at the same time, the opening degree limiting arm 40 is inserted into the gap of the hall door 24. By adjusting the direction of the opening restricting arm 40 (the direction orthogonal to the contact plate 34) as described above, the opening restricting arm 40 is inserted when the contact plate 34 is brought into contact with the landing door 24. It is easy to do.
