As shown in FIG. 2, the clip 2 has a substantially gate-shaped shape having a pair of legs 9 and 9 extending in the same direction from both sides of the connecting portion 8. The legs 9 and 9 are inserted across the eyelets 51 and 51 arranged to face each other at regular intervals along the left and right edges of the left and right seats 50 and 50, and are inserted into the left and right through holes 6 and 6 described above. Is also inserted. Further, in the facing positions on the inside of the leg portion 9, the eyelet 51 in contact with the back surface of the connecting portion 8 and the notch grooves 11 and 11 are bored in the lateral direction while maintaining a gap corresponding to the wall thickness of the standing plate 5.

As shown in FIG. 3, the locking member 3 is a vertically elongated plate-like body provided with a pair of acting portions 13 and 13 on the left and right sides of a long groove 12 running vertically in the center. The locking member 3 is slidably attached to the back side of the upright plate 5 along the long groove 12 with respect to the shaft support portion 15 of the upright plate 5 (FIGS. 6, 7, and 8). The shaft support portion 15 is formed with a collar 10 for making the locking member 3 inseparable.

The locking member 3 is for preventing the clip 2 holding the sheet 50 from coming off. First, as a preparatory step, the locking member 3 supported by the shaft support portion 15 on the back side of the standing plate 5 is formed in the long groove 12. Pull up along the line, and when the shaft support 15 comes to the lower end position of the long groove 12, rotate the locking member 3 with the shaft support 15 as a fulcrum and tilt it sideways, and place it on one of the previously described pieces 17 to stand by. (See Fig. 6). Next, the operation of preventing the clip 2 through which the through holes 6 and 6 are inserted is performed along the long groove 12 after the locking member 3 is rotated to stand upright from the standby position (see FIG. 7). When the stop member 3 is slid so that the shaft support portion 15 comes to the upper end position of the long groove 12, both the acting portions 13 and 13 of the locking member 3 are fitted into the notch grooves 11 and 11 and the clip 2 is formed. It becomes impossible to pull out, and it is possible to prevent the clip 2 from coming off from the fixing member 1 (see FIG. 8).

Next, using the left and right through holes 6b and 6b in the upper and lower middle (middle) of each fixing member 1 corresponding to the positions of the facing eyelets 51 and 51 at the abutting portions of the left and right sheets 50 and 50, the eyelets are used. Insert the legs 9 and 9 of the clip 2 across 51 and 51, press both edges of the left and right sheets 50 and 50 between the left and right eyelets 51 and 51 from above with the clip connecting portion 8, and further press the back side of each sheet 50. The locking member 3 in the standby position is rotated to stand up, the locking member 3 is slid using the long groove 12, and the acting portions 13 and 13 of the locking member 3 are made into the cut groove 11 of each leg portion 9. , 11 are fitted into the eyelets and 11 so that the clip 2 cannot be removed, and the connecting portion 8 of the clip firmly presses between the eyelets 51 and 51 (see FIG. 9).
In this way, the left and right seats 50, 50 are sequentially held by the support column 60 by using the fixing member 1, the clip 2, and the locking member 3.

The upper and lower left and right through holes provided in the fixing member 1 in the vertical direction are used for the portions where the upper and lower and left and right sheets 50, 50, 50 and 50 are in contact with each other, and the lower sheet 50 is used. By using the lower left and right through holes 6c and 6c in the lower tiers for 50 and 50, and by using the left and right through holes 6a and 6a in the upper tiers for the upper sheets 50 and 50, the upper and lower and left and right seats can be made. Even at the abutting point, the clip 2 and the locking member 3 can be reliably held by the support column 60 by pressing the upper and lower left and right edges with the connecting portion 8 by the same usage as described above.
In this way, the sheet of the column can be reliably held only by inserting the pair of legs of the clip through the eyelets and the through holes, and further passing the locking member through the notch groove between the legs. Further, when removing the sheet, the locking member can be easily lifted upward and pulled out from the notch grooves of the pair of legs, and then the clip can be easily pulled out from the through hole and the eyelet.
