Here, the contact point between the telescope side floor 1 on which the first existing rail 3 is installed and the dome side floor 2 on which the second existing rail 4 is installed and the temporary rail 5 is the primary mirror. The so-called “carrying vehicle” (hereinafter, simply referred to as “carrying vehicle”) 7 is different before passing over the temporary rail 5 before so-called and after passing after passing over.

That is, the floor 1 on the side of the telescope and the floor 2 on the side of the dome are different from each other in basic rigidity, and when the carrier truck 7 straddles the floors 1 and 2, one of the floors 1 or 2 is moved by its own weight. The temporary rail 5 inclines as it sinks. Therefore,

So that the carriage 7 rides on the temporary rail 5 on the traveling direction side of the carriage 7 with respect to the vertical line Z as a boundary.
It is formed into a curved surface shape having a radius curvature. The boundary point (perpendicular line) Z in this case is determined from the amount of deviation between the telescope-side floor 1 and the dome-side floor 2 during its own weight deformation.

Next, the operation of the first embodiment will be described. When the carrier 7 travels from the telescope-side floor 1 toward the dome-side floor 2, the fitting recesses 5 of the existing rail 5 are fitted into the fitting projections 30 and 40 of the first existing rail 3 and the second existing rail 4.

52a and the lower rounded curved surfaces 51b and 52b are formed. Also, on both sides of the fitting convex portions 30 and 40, as in the case of the second embodiment, the side curved surface 30b,
40b is formed in advance. Therefore, also in the fourth embodiment, the same effect as in the first and second embodiments can be obtained.

In each of the above-mentioned embodiments, the temporary rail 5 is installed between the first and second existing rails 3 and 4, and the traveling body is run on these rails.
The traveling body is not limited to the above, and may be a traveling body for any purpose as long as the traveling body can travel on the rail. Also, although the wheels have been described as being of the double brim type, the temporary rail 5 may be of the single brim type because it can withstand the twisting force.
