Abstract:
An elevator door device includes a failure detection vane mounted on a safety shoe, and a failure detection roller to be brought into contact with the failure detection vane to turn on a shoe switch. The failure detection roller is mounted only on an OFF-failure detection floor. In a case where the shoe switch is turned off when a door is fully closed on the OFF-failure detection floor, it is determined that the safety shoe has OFF failure, and in a case where the shoe switch is turned on when the door is fully closed on an ON-failure detection floor, on which the failure detection roller is not mounted, it is determined that the safety shoe has ON failure.
