A clip 9 which constitutes a fixing means together with the through hole of the outer panel 3 and stops relative movement between the outer panel 3 and the top plate 1 by being inserted into each opening 32 is provided.
It is made of hard synthetic resin, and has a flange 9 at one end 91a of the cylindrical body 91.
2, the inner diameter and the outer diameter of the cylindrical body 91 each have a diameter different from that of the other part in the vicinity of the other end 91b, and from the lower surface of the upper edge 3a with the respective openings 7, 32 superimposed. The base 9B includes a deformable base 9B to be inserted and a pin 9P fitted into the base 9B to increase the diameter of the base 9B near the other end 91b. That is, the base 9B is attached to one end 91a of the cylindrical body 91 by a later-described head plate 9 of the pin 9P.
A donut-shaped collar 92 having a concave portion 94 for accommodating therein 3 is provided. The inner diameter of the base 9B is slightly smaller than the other part near the other end 91b, so that when the pin 9P is inserted, the wall surface of the small inner diameter part 95 is pushed outward. The small inner diameter part 95
Has a large outer diameter portion 96 having an outer diameter different from that of other portions. Large outer diameter part 96
Is generally the same as the openings 7 and 32, and becomes larger than the openings 7 and 32 when the pin 9P is inserted into the cylindrical body 91. The pin 9P is attached to one end 98 of a cylindrical body 97 having an outer diameter substantially equal to the inner diameter of the base 9B except for the small inner diameter portion 95, and a head plate 93 made of a disk whose end surface is convexly curved.
Are formed integrally with the cylindrical body 97.

In the above configuration, a method of assembling the desk D of this embodiment will be described. First, the top plate 1 is placed on the floor with its lower surface facing upward. Next, one of the left and right side panels 2 is attached to the top plate 1. The side panel 2 includes a dalma pin 9 erected on the upper surface of the arm 24.
The head 51 of the P is connected to the large-diameter through hole 61 of the darma hole 6 of the top plate 1.
And place it on the lower surface of the top plate 1. From this state, the side panel 2 is slid and moved to the side opposite to the use end while the top panel 1 is fixed so as not to move. As a result, the Dharma pin 9P is fitted into the small-diameter through hole 62 of the Dharma hole 6, and the non-use end side of the side panel 2 is engaged.
Next, the bolt 4 is inserted into the through hole 42 on the use end side of the side panel 2.
Is inserted, and the bolt 4 is tightened to fasten the top plate 1 to the side panel 2. Similarly, the other side panel 2 is fixed to the top plate 1.

After fastening the pair of left and right side panels 2,
Attach the outer panel 3. First, the outer panel 3 is placed on the reinforcing member 11 b of the top plate 1 so as to be located between the side panels 2. Then, the opening 32 of the outer panel 3 is aligned with the opening 7 of the top plate 1, the bolts 8 are inserted into bolt holes 34 provided on the left and right sides of the outer panel 3, and the bolts 8 are lightly tightened to temporarily fix. And In this state, the outer panel 3 rattles, but the openings 32 and 7 of the outer panel 3 and the top plate 1 are overlapped, and the base 9B of the clip 9 is closed until the flange 92 abuts on the outer panel 3. Push it into 32, 7 and attach. After this, the base 9B of each clip 9
Insert the pin 9P into the. The pin 9P does not require any force until its tip reaches the small inner diameter portion 95, but requires some force when inserted below it. Then, when the head plate 93 of the pin 9P is pushed until it enters the concave portion 94 of the base 9B, the small inner diameter portion 95 of the base 9B is expanded by the pin 9P, so that the large outer diameter portion 96 of the base 9B is larger than the inner diameter of the opening. The diameter becomes large, and the base 9B does not come off from the opening. After the clips 9 have been inserted into all the openings 32 and 7, the bolts 8 of the left and right side panels 2 are tightened, and then placed on the floor with the side panels 2 facing down.

As described above, since the desk D is assembled on the floor with the top plate 1, the mounting of the outer panel 3 eliminates the work in a narrow space. That is, the position where the outer panel 3 is fixed to the side panel 2 with the bolts 8 is located on the lower side in the use state, but becomes the upper part of the side panel 2 when the top plate 1 is placed on the floor, and The work can be performed in a place where there is an open space, and there is no condition for the working posture, and the work can be performed by a driver having a long normal handle. However, when the top plate 1 is positioned on the lower side, the openings 32, 7 for inserting the clips 9 are provided.
Is located on the lower side, but the operation of inserting the clip 9 can be performed by sandwiching the base 9B and the pin 9P between two fingers. When the operation position is lowered, the operation becomes difficult. The upper edge 3a of the outer panel 3 can be reliably fixed to the lower surface of the top plate 1 although it is a simple operation that does not require skill. Rather, since the force is applied from the top to the bottom, the force can be applied to the clip more easily than when the work is performed from the lower side to the upper side with the top plate 1 up, and the workability is improved. I'm doing better.
Therefore, the work can be performed without difficulty, the assembling becomes easy, the working time can be shortened, and the working efficiency can be greatly improved. Further, since only two bolts 8 are used for mounting the outer panel 3, the weight can be reduced without leaving any problem in strength.

In addition, the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.
