When the above work is completed, an adhesive is prepared, and the opening on the upper end side of the shaft hole of the upper boss portion 25a of the upper member 25 of the adjustment base 24 of the support leg 18 is used as an adhesive injection port and adhered from there. Inject agent G (see FIG. 9A).

The injected adhesive G passes from the shaft hole of the upper boss portion 25a of the upper member 25 of the adjusting table 24 to the shaft hole of the lower boss portion 26a of the lower member 26, and passes through the shaft hole of the lower boss portion 26a of the lower member 26. It reaches the upper end portion of the support column 22 of the leg portion 20 screwed to the support column 22 and flows into the shaft hole 22b formed in the support column 22. Then, using this shaft hole 22b as an adhesive introduction path, it reaches the lower end of the shaft hole 22b, that is, the foundation floor 1.

Then, the adhesive G propagates from there through the gap between the foundation floor 1 and the lower surface of the base plate 21, radiates from the central portion of the base plate 21, and reaches the peripheral edge portion of the base plate 21 (FIG. 9 (b)). reference).

At this time, as shown in FIGS. 3 and 4, the base plate 21 is formed with the central recess 21a and the radial recess 21b, so that the central recess 21a and the radial recess 21b are formed on the lower surface side of the base plate 21. The adhesive G flows into the concave space portion and flows along the concave space portion, so that the adhesive G easily spreads to the peripheral edge portion of the base plate 21.

Further, as shown in FIGS. 3 and 4, a confirmation window portion 21c is formed in the plate portion of the base plate 21, and the operator visually confirms this from the upper surface side of the base plate 21. It is possible to easily determine whether or not a sufficient amount of the adhesive G has been injected and whether or not the injected adhesive G has spread to the position of the confirmation window portion 21c of the base plate 21.

At the same time, the injected adhesive G passes through the shaft hole of the upper boss portion 25a of the upper member 25 of the adjusting table 24, the shaft hole of the lower boss portion 26a of the lower member 26, and the lower member 26. It reaches the upper end of the support column 22 of the leg portion 20 screwed to the lower boss portion 26a, and lower from the upper end portion of the screw connection portion where the lower boss portion 26a of the lower member 26 and the support column 22 of the leg portion 20 are screwed together. It also flows into the gap between the side member 26 and the support column 22 (see FIG. 9B).

At this time, as shown in FIG. 4, since the horizontal hole 22c is formed in the support column 22 at a position near the upper end portion, the adhesive G flowing into the shaft hole 22b passes through the horizontal hole 22c. Since it reaches the inner side surface of the lower boss portion 26a of the lower member 26 and also flows into the gap between the respective members of the screw joint portion, the adhesive G is better than the one in which the horizontal hole 22c is not formed. Is easy to flow into the screw joint.

Then, the base plate 21 of the support leg 2 is fixed to the support floor 1 and at the same time, the adjustment table is fixed so that the support leg 2 does not move from the installation position on the foundation floor 1 due to the hardening of the injected adhesive G. These screw joints are fixed so that the screw joints of the 24 and the leg 20 do not rattle or loosen these screw joints.
