In the flat plate double-sided linear motor type elevator shown in FIG. 1, between the secondary conductors 15 in the conventional system in which power is supplied to the primary conductor 14 through the power cable 20 as shown in FIG. Since the power cable 20 passes through the power cable 20, the power cable 20 may come into contact with the secondary conductor 15. In order to prevent the contact between the secondary conductor 15 and the power cable, it is necessary to provide a pulley 21 at the bottom of the hoistway 1 and connect the power cable 20 to the primary conductor 14 via this pulley 21.

Therefore, by supplying power to the primary conductor 14 through the conductive material 11 in the counterweight guide rail 9, the power cable 20 and the power cable pulley 21 are not required, and the hoistway can be simplified. Further, when the weight of the electric power cable 20 is increased during a high stroke, the car 6 supporting the electric power cable 20 is also stiff and the load applied to the linear motor is also increased. However, these effects can be eliminated when the power cable 20 is no longer needed.
