[Prior Art] Conventionally, as shown in FIG. 17, the side panel of this type of desk has a downwardly U-shaped cross section with an inwardly bent peripheral edge piece on the upper surface of the base part a. A two-cylindrical body plate C having a cylindrical shape is disposed, and a peripheral bent piece of the body plate C is joined to the upper surface of the base portion a by welding or the like.

[Problems to be Solved by the Invention] However, in such a configuration, since the upper end of the body C is closed with a frame material etc. for attaching the top plate, the interior of the body C is closed. is close to a closed structure.

Therefore, when this side panel is immersed in a processing solution during the cleaning process, etc. when painting, the solution will be sucked into the body plate C through minute gaps etc. due to the suction effect caused by the temperature drop. There is a problem that it rarely remains inside for a long time.

In order to deal with such a problem, some models have a drain hole d formed in the center of the upper surface of the base part a to communicate the space S in the body plate C to the outside, but if water drains at such a position, Even if the extraction hole d is provided, if the side panel is even slightly inclined, it is impossible to extract all the solution, and it is necessary to wait for it to be dissipated by evaporation. Therefore, there is a problem in that rust is likely to occur inside the body plate C during this time.

The cover section 81 includes an upper wall 81a, left and right side walls 81b, and an end wall 81c that covers the use surface side end 51t of the base section 5, and is integrally molded from synthetic resin. . The upper wall 81 of this first cover part 81
The end edge glat of a is connected to the lower edge 62 of the end wall 62 of the body 6.
a and the base part 5, and the first
Between the cover part 81 and the base part 5, the first cover part 81 moves toward the use side, and the first cover part 8
An elastic engagement portion 82 is provided to prevent the use surface side end portion 81d of 1 from lifting up. The elastic engagement part 82 is formed by a claw 82a provided on the inner surface of the side wall 81b of the first cover part 81 and a width dimension corresponding to the mold 82a provided at the lower edge of the side wall 51a s 52a of the base part 5.

With such a configuration, before the base cover 8 is attached, there is a continuous gap between the lower edge 6c of the body 6 and the base 5 that communicates with the internal space S of the body 6. A gap C is formed. Therefore, even if a solution enters the internal space S of the body 6 during a painting process or the like, the solution easily flows out through the gap C. That is, since this gap C opens toward the entire circumference of the side panel 2 along the lower edge 6C of the body plate 6, even if the side panel 2 is inclined, for example, one side of the side panel 2 The solution flows out from the gap C that opens on the other side of the side panel 2, and air enters the body 6 from the gap C that opens on the other side of the side panel 2. Therefore, the solution within the body 6 quickly flows out. Therefore, it is possible to effectively prevent problems such as unnecessary solution remaining in the body 6 for a long period of time and promoting internal rust. At the completion stage, this gap C is closed by the base cover 8 as described above, so there is no problem in terms of appearance.

Note that the structure for attaching the base cover to the base portion is of course not limited to that described above, and may be, for example, as shown in FIGS. 14 and 15. That is, the elastic engagement portion 282 of this embodiment is
An elastic pawl 282b that protrudes approximately horizontally from the inner surface of the end wall 81c of the use surface side of the first cover portion 81 and has an undercut portion 282a on the upper surface side, and an upper wall 52a of the inner wall member 52 of the base portion 5. The elastic claw 282b is elastically engaged with the engagement hole 282C from the lower surface side of the upper wall 82a, which is a downward horizontal surface. Also in this case, the edge 81at of the first cover part 81 on the side of the unused surface is connected to the upper wall 51a of the base part 5.
The cover part 81 is inserted into the gap S between the cover part 81 and the end wall 62 of the body part 5, which bulges out in a partially circular arc shape, to prevent the cover part 81 from bulging out or floating upward. Note that 282d is a cavity necessary for forming the undercut portion.

[Effects of the Invention] Since the present invention has the above configuration, the following effects can be obtained.

First, attach the torso to the base with its lower edge floating,
Since a continuous gap is formed between the lower edge and the base part that communicates with the inside of the body part, it is easy to quickly and reliably remove processing liquid etc. that have entered the body part during the manufacturing process. Therefore, it is possible to provide a desk with excellent durability and no internal rust.

Then, on the lower surface of the body, a plurality of tongues with a narrow width on the tip side are protruded, and the tips of the tongues are inserted into the slit made in the upper wall of the base and fixed firmly. If this is done, the body part can be firmly joined to the base part with the gap formed.

Moreover, if the end wall of the body on the use side is bulged in a partially arced shape, the appearance of the body can be made excellent. If this bulging end wall hides the edge of the first cover part that constitutes the half part of the use side of the base cover, and prevents the cover part from lifting up, Even if the base cover is composed of two cover parts that are easy to assemble, the joint between them will not be unsightly and exposed to the outside, and the ends of the cover parts can be reliably prevented from swelling or lifting. .

In this way, when the end of the first cover part on the non-use surface side is inserted under the end wall of the body part to prevent it from rising, the first cover part and the base part By simply providing an elastic engagement part between the parts that prevents the first cover part from moving toward the use surface side and prevents the end of the first cover part on the use surface side from lifting up, it is possible to create an exceptional effect. It becomes possible to securely attach the base cover to the base portion without using any fasteners or the like.

In particular, if the elastic engagement part is made up of a claw provided on the inner surface of the side wall of the first cover part and a cutout part provided at the lower edge of the side wall of the base and having a width dimension corresponding to the mold. The elastic engagement portion can prevent the edge of the cover portion on the use surface side from lifting up, and at the same time, the cover portion slides toward the use surface side so that the edge of the non-use surface side
It can effectively prevent it from coming off the end wall of the body.

The elastic engagement portion includes an elastic pawl that protrudes approximately horizontally from the inner surface of the end wall on the usage surface side of the first cover portion and has an undercut portion on its upper surface, and an engagement portion that is provided on the downward horizontal surface within the base portion. If the elastic claw is made to elastically engage with the engagement hole, the first cover part can be reliably attached, and this cover part It becomes possible to perform the molding more easily. That is,
According to such a configuration, by simply providing a single elastic engagement portion, it is possible to prevent the cover portion from moving toward the use surface side and prevent the edge of the cover portion from coming off from the end wall of the body portion. It can be prevented. Therefore, the first cover part can be reliably attached to the base part, and it is easy to prevent complications such as the mold used for molding the cover part and the press mold for manufacturing the base part. .

Moreover, if the base part is made of a pipe structure consisting of an outer wall member and an inner wall member as described above, the base part will be strong against bending and torsion. Then, if the bracket for attaching the adjuster that needs to support the entire load of the desk is fixed by spot welding to the area where the side wall of the outer wall member and the side wall of the inner wall member overlap,
The base portion as a whole has high strength, and can comfortably support a large load without increasing weight. In this case, if the ends of the outer wall member and the inner wall member are opened to the outside, the spot welding electrode can be inserted through the open part, making the spot welding work particularly easy. .

In addition to the above-mentioned spot welding, if the side wall of the outer wall member and the upper wall of the inner wall member are joined by CO2 welding,
Since it is possible to reliably prevent the inner wall member from being misaligned with respect to the outer wall member, it is possible to particularly increase the support strength of the base portion.
