Abstract
Car doors hanging down via door hangers are disposed on a door rail that is disposed on a vertically-oriented frame disposed above an entrance of a car and extends along a width direction of the entrance of the car. One of a magnetic proximity switch and a target for detecting that the car doors are fully open and fully closed is disposed on a horizontal part extending from an upper end of the frame toward the entrance of the car. The remaining one of the magnetic proximity switch and the target is disposed on an extending part extending from each of the door hangers so as to be opposed in a vertical direction to the one of the magnetic proximity switch and the target for detection.
