摘要： PROBLEM TO BE SOLVED: To provide an elevator device capable of detecting a rope-like body, which is caught by car doors when closing the doors, with simple structure without requiring electric power.
SOLUTION: A detector 14 is provided in car doors 7 (7A, 7B) on a door stop side to project from a door stop side end when closing the door by using the door closing motion of the doors 7 as motive power, and a detecting means 16 is provided to detect projection of the detector 14. Since the detector 14 is projected from the door stop side end by the door closing motion of the car doors as motive power, a driving machine for driving the detector 14, which requires electric power, and wiring for power are unnecessary, and as a result, structure can be simplified.
