Abstract:
An elevator door device provided with a malfunction detection vane 28 mounted on a safety shoe 25 and a malfunction detection roller which comes into contact with the malfunction detection vane 28 and switches on a shoe switch 27. The malfunction detection roller 29 is installed only on an off-malfunction detection floor.
