Abstract

In an elevator car door apparatus, a locking member is disposed on a blade-carrying car door, and is displaceable between an unlocked position and a locked position interdependently with movement of a doorstop-side blade. A guiding portion is disposed on the locking member. A guiding cam is disposed outside the blade-carrying car door. When the car is positioned outside an appropriate floor alignment position, the blade-carrying car door moves in an opening direction, the guiding portion moves along the guiding cam, the locking member displaces to the locked position, and the doorstop-side blade also displaces to a locking accommodating position, the locking member catches in a fixed latch, and movement of the blade-carrying car door in the opening direction is prevented.
