However, with such a structure, there is a possibility that the mounting operation of the panel pressing member with respect to the support leg is likely to vary greatly, and it may not be possible to sufficiently screw it. That is, in this type of double floor, the height of each support leg is adjusted so that the upper surface of the floor panel is horizontal regardless of the ups and downs of the floor such as concrete. Therefore, depending on the location, there is a large difference in the screwing position between the upright bolt of the base and the nut of the elevating body forming the support legs. As a result, in the support leg in which the nut of the lifting body is screwed to the lower position of the standing bolt, the size of the standing bolt protruding above the nut is large, and the panel pressing member is screwed and tightened at that portion. In addition, the amount of rotation operation becomes large. On the other hand, in the support leg in which the nut of the lifting body is screwed and adjusted to the high position of the standing bolt to increase the height, the dimension of the upper end portion of the standing bolt protruding above the nut is too short, It may happen that the panel pressing member cannot be sufficiently screwed into the upright bolt.

An object of the present invention is to eliminate such a problem.
