1 to 6, the fixing device 100 includes an upper surface member 110 that contacts an upper surface 312 of a top plate 310 of the table 300 and a side member 120 that contacts an edge 312 of the top plate 310.
[0023]
The fixing device 100 is provided with a bottom member 200 to which the screw 210 is screwed, and the screw 210 is pressed against the bottom surface 314 of the top plate 310. The bottom member 200, the fastening screw 210 and the top member 110 constitute a so-called vise mechanism, and fixes the fixing device 100 to the top plate 310. A shoe 212 that is in direct or indirect contact with the bottom surface 314 of the top plate 310 is rotatably attached to the upper end of the screw 210. As a result, even when the contact force of the shoe 212 against the bottom surface 314 increases, the tightening of the screw 210 is not hindered by the frictional force on the shoe 2121. Further, there is no possibility that the table cloth 500 is damaged due to a twisting force or the like acting on the table cloth 500 by the shoes 212.
[0024]
The side surface member 120 has a horizontal cross-section right angle along the edge 312 of the substantially right-angled corner 316 of the top plate 310, and is in close contact with the corner 316.

A friction member 150 is attached to the bottom surface 112 of the upper surface member 110, and the frictional force of the upper surface member 110 against the table cloth 500 is increased. This prevents the table cloth 500 from shifting when tightened by the vise mechanism.
[0027]
When a tensile force is applied to peel the table cloth 500 from the top plate 310, a moment M2 (FIG. 6) for rotating the fixing device 100 outward is generated in the fixing device 100. The contact with the edge 312 generates a reaction force FR2 facing the moment M2. Thereby, the fixing device 100 can firmly support the table cloth 500 even when the moment M2 is generated, and can prevent displacement.
[0028]
The top member 110, the side member 120, and the bottom member 200 are integrally formed members formed by pressing a metal plate, and the manufacturing cost is low. Further, the shape of the side member 120 having a right angle in the horizontal cross section ensures sufficient strength and rigidity as a vise mechanism.
[0029]
Conventionally, there is no fixing device that can be attached to the corner 316, and the present embodiment has enabled the use of the fixing device 100 in the corner 316 with the above configuration. Thereby, the possibility that the fixing device 100 becomes an obstacle to the article arrangement on the table 300 is reduced.
