Since the first embodiment of the present invention is a structure for elevating the boarding car 20 between the wire rope 50 fixed to the upper and lower portions, it is important that the wire rope 50 maintain a constant tension.

By the above-described tension maintaining device, it is possible to increase the friction force between the sheave and the wire rope so that the wire rope always maintains a constant tension.

In addition, when there are two driving sheave as shown in FIG. 3a , one end of each wire rope 50 is fixed to the upper fixing part 51 provided on the upper part of the ramp, and the other end of the wire rope 50 is the first driving sheave (21a) → the second driving sheave 21b → the first driving sheave 21a → The second driving sheave 21b is wound in sequence, and then fixed to the lower fixing part 52 provided at the lower part of the ramp.
