[0084] Image 6 It is a front view showing the outline of the ends of the car position adjusting ropes in the second embodiment of the double-deck elevator according to the present invention. exist Image 6 In , parts having the same structure as those of the first embodiment are denoted by the same symbols, and repeated descriptions thereof are omitted. exist Image 6 Among them, the hydraulic cylinder 25 a is configured to drive the fixing member 32 supporting the spring as the elastic body 19 . According to the structure of this embodiment, since the vibration amplitude generated by the repeated load acting on the elastic body 19 only needs to be able to cope with the fluctuation of the load, the required strength of the elastic body 19 can be reduced, and the size of the elastic body can be reduced. . The correction of the position of the elevator car can obtain the same effect by adopting the same structure as that of the above-mentioned embodiment. This embodiment c...

[0086] Figure 7 It is a front view showing the outline of the ends of the car position adjusting ropes in the third embodiment of the double-deck elevator according to the present invention. Figure 7 The illustrated fixed member moving device 25a is configured to drive a fixed member 26a suspending a wire rope as the car position adjusting rope 17 by means of a ball screw device 25a. The ball screw shaft 33 is passed through the fixing nut 34 for the ball screw fixed on the fixing member 26a, and the rotational torque is converted into the linear motion of the ball screw by the ball screw driving device 35 (such as a servo motor), thereby passing the ball screw shaft 33 to correct the variation of the elevator car position. The detection of the position of the elevator car can be accomplished by the same structure as that of the above-mentioned first embodiment. Since the ball screw device can be driven by electricity, it does not require the use of pressure fluid, that is...
