Is a partial cross-sectional view showing a back plate attached to one of the back rods, and FIG. 6B is a side view thereof. Chair 0
The backrest of No. 1 is such that a mounting plate 03 made of a metal plate is welded to a back rod 02 extending from a seat formed by bending a metal pipe or the like, and the mounting plate 03 is slightly curved in a cross-sectional shape into an arc shape. It has a structure in which the back plate 04 is screwed.

った状態となっている。The welding is, for example, welding using a welding machine, and in order to firmly fix the mounting plate 03 to the back rod 02, welding is performed from the front and rear of the mounting plate 03. Therefore, after welding, the backside welded portion 06a and the frontside welded portion 06b are in a raised state.

る。As shown in FIG. 6 (b), the screw fastening is
Screws 05 may be screwed into the upper and lower two positions from the back side of the mounting plate 03 to the nut portion 04a in which the female screw is previously cut on the back plate 04, whereby the back plate 04 is fixed to the mounting plate 03. .

【発明が解決しようとする課題】しかしながら、上述の
椅子01の背板取付構造においても、次のような解決す

た。However, even in the back plate mounting structure of the chair 01 described above, the following problems to be solved remain. That is, when performing positioning before welding, the back rod 02 is, for example, tubular and the mounting plate 03
If the plate is plate-shaped, the alignment for the butting may become unstable, and temporary fixing welding may be troublesome.
The deviation of the mounting position due to the misalignment during positioning affects the accuracy of the screwing position after welding, and there is a possibility that the back plate 04 cannot be mounted on the mounting plate 03.
【0006】また、背杆02の外側面と取付板03の溶

と、背面溶接部06aに亀裂が生じる恐れもあった。Further, since the contact area between the outer side surface of the back rod 02 and the mounting plate 03 at the time of welding is small, the welding strength is weak, and it is necessary to raise the welding portion to reinforce the welding strength. Therefore, the back welded portion 06a is exposed from the back side of the chair 01 and does not look so good. Moreover, when an external force acts on the back welded portion 06a and an external force acts, the back welded portion 06a may be cracked. There was also.

あった。Further, as shown in FIG. 6 (a), in order to change the front position of the back plate 04 to a position flush with the tip of the back rod 02 shown by the broken line, the welding position of the mounting plate 03 is changed. Although it is conceivable that the back plate 02 is made thicker by changing the above, it is a labor-intensive work that increases the cost.
