It is possible to elastically expand the space between the edge members 11e and 11e of 1 and take it out from any part of the horizontal frame 6 onto the tabletop. Further, the cord 30 in the groove A of the support column 4 can be taken out from the notch 31 (FIG. 1) at the lower end of the cover plate 9 and connected to an external wire. Also, the horizontal frame groove B
The inner cord 30 branches into the through groove 1 of the bottom member 36.
6e (FIG. 7), it can be taken out to the bottom surface of the table board 1, and can be wired to an electric appliance installed on a shelf board or the like installed on the bottom surface.

In FIGS. 3 and 8, 32 is a support shaft mount for a stand such as a lamp, a telephone stand, or a document shelf used on a table, and is mounted on a base frame 33 having a downward U-shaped cross section. Mounting plate 34
A fixing plate 35 having a cross-sectional shape is fixed to this using the mounting screws 36 and nuts 37 fixed to the lower surface of the mounting plate 34, and the through hole 35' of the fixing plate 35 (Fig. 8) The lower end stepped portion of the support shaft 38 is brought into contact with the mounting plate 34, and the small diameter screw portion 38' formed at the lower end of the support shaft 38 is passed through the mounting plate 34 and the base frame 33. The support shaft 38 is fixed by tightening with nuts 39 on the lower surface, and by fitting the base frame 33 into the groove B so as to be able to slide freely, the support shaft mounting base 32 is fixed in the longitudinal direction within the groove B. The support shaft 38 is passed between the edge members 11e and 11e of the cover plate 11 and protrudes upward, and the support shaft 38 is used as a stand by attaching a lamp, a telephone stand, etc. to it. It is also possible to use two such support shafts and attach a shelf board or the like between them.

When the mounting screw 36 is tightened, the lower edge of the fixing plate 36 expands outward, and the inner plate 1
3 and 13, it can be firmly fixed in that position. Furthermore, by loosening the mounting screw 36, it can be slid to any desired position and fixed again at that position.

As described above, in the spindle mounting device of the present invention, the spindle mount 32 is fitted so as to be movable in the longitudinal direction within the groove B, and can be easily and reliably fixed in the groove B by simply tightening the mounting screw 36. Therefore, a support shaft for a stand such as a lamp, a telephone stand, or a document shelf used on a table can be moved and fixed at a desired position within the groove B, which is extremely convenient.
