PROBLEM TO BE SOLVED: To inexpensively provide a small elevator power feeding device capable of feeding power to a car of an elevator without using an elevator cable easy to generate problems of wear and car oscillation and suppressing heat generation. SOLUTION: A primary power source device 4 provided on an elevator control device 14 supplies sine-wave current changing with time. A guide line 5 laid in almost parallel to a moving direction of the car 2 of the elevator in a hoistway 1 of the elevator carries current supplied from a temporary power source device 14 and is provided with a receiving coil. A receiving unit 6 mounted on the car 2 takes out current from the guide line 5 by electromagnetic induction and utilizes current for illumination of the car 2, opening and closing of a door and charging of a battery. |
