Elevator Door Stopping Device

An elevator door stopping device which can prevent that elevator door is closed by itself when power supplied to a motor for opening and closing the elevator door is interrupted, an improvement of the elevator door stopping device characterized in that a first magnetic body is fixed on a shaft rotating in interlock with opening and closing of the elevator door so as to generate a magnetic force in a radial direction perpendicular to the shaft, and a second magnetic body is fixed on a fixed face spaced apart from the first magnetic body at a predetermined interval in the radial direction in such a manner that the second magnetic body has the opposite pole to the first magnetic body, so that a magnetic force is generated between the first magnetic body and the second magnetic body in the radial direction perpendicular to the shaft.
