(11) is brought into contact with the upper surface of the top wall (9), and in this state, the downwardly protruding portion (13) of the lower wall of the coupling wall (5) is fitted into the concave portion (12) of the second connecting member (11). However, at this time, the coupling wall (5) is made elastically deformable with its base as a fulcrum. Therefore, due to the tolerance at the time of manufacturing the first connecting member (6) and the second connecting member (11). Even when the concave portion (12) of the second connecting member (11) and the downward convex portion (13) of the first connecting member (6) do not face each other, the coupling wall (5) can be elastically deformed as appropriate to achieve this. Recessed downward projection (13)
(12). Then, along with the fitting, the pin hole forming grooves (1
A pin hole (15) is formed by 4), and a coupling pin is inserted into the pin hole (15).
(16), the first connecting member (6) and the second connecting member (1
1) are connected, and as a result, the panel (22) fitted in the horizontal panel fitting portion (4) of the first connecting member (6) and the vertical panel fitting portion (10) of the second connecting member (11) are fitted. Fitted panel
(23) will be connected.

The rising portion (19) of the outer wall (8) extends obliquely outward and upward, and the outer surface of the downwardly projecting portion (13) of the first connecting member (6) is also inclined accordingly. Surface, and with such a structure, the downward convex portion (13) into the concave portion (12).
Can be easily inserted. The outer wall (8) is the rising part (19)
The structure extends downward from the upper end of the.

Embodiment 2 As shown in FIG. 2, first, the basic structure of the first connecting member (6) is the same as that of the above-mentioned Embodiment 1, and the same reference numerals are given and the description is omitted. .

On the other hand, the second connecting member (11) has an inclined wall (2) extending obliquely outward and downward from the outer edge of the top wall (9).
0) is provided, and the lower edge of the inclined wall portion (20) is connected to the upper edge of the vertical portion (17) of the outer wall (8). The outer wall (8) extends further downward from the lower edge of the vertical portion (17).

In this embodiment, the upper edge of the vertical portion (17)
Since the inclined wall portion (20) is provided, the first connecting member (6)
When the downward convex portion (13) of the second connecting member (11) is fitted into the concave portion (12) of the second connecting member (11), the downward convex portion (13) of the first connecting member (6) is inclined by the inclined wall of the second connecting member (11). It slides down the surface of the portion (20) and is guided to the concave portion (12). Therefore, the concave portion (12) and the downward convex portion (1
The fitting of 3) can be performed very easily. In this embodiment, the connecting wall of the first connecting member (6) is provided because the inclined wall (20) extending obliquely outward and downward from the outer edge of the top wall (9) is provided.
(5) is made longer than in the case of the first embodiment, so that the coupling wall (5) can be elastically deformed to a greater extent than in the case of the first embodiment, and the downward projection (13) with respect to the recess (12). Will be further improved.

Third Embodiment As shown in FIG. 3, first, the basic structure of a first connection member (6) is the same as that of the first embodiment. .

Also in this embodiment, as in the second embodiment, the fitting of the concave portion (12) and the downwardly protruding portion (13) can be performed very easily due to the presence of the inclined wall portion (20).

[0023]

According to the present invention, the connecting wall of the first connecting member is
When the lower surface of the lower wall of the first connecting member is in contact with the upper surface of the top wall of the second connecting member, the downwardly projecting portion of the coupling wall is elastically deformable so as to correspond to the concave portion of the second connecting member. Therefore, even when the downward projection of the connecting wall of the first connecting member does not face the concave portion of the outer wall of the second connecting member due to a tolerance in manufacturing the first connecting member and the second connecting member, the connecting wall may be formed. Is appropriately elastically deformed so that the downwardly projecting portion and the recessed portion can be fitted. Therefore, the horizontal panel and the vertical panel can be connected even if the tolerances at the time of manufacturing the first connection member and the second connection member vary. Also book
According to the present invention, as described above, the lower part of the connecting wall of the first connecting member is provided.
When fitting the direction convex part into the concave part of the outer wall of the second connection member,
The downward convex part slides down the inclined wall part provided above the concave part.
As a result, the convex portion is introduced into the concave portion.
The connection between the connection member and the second connection member is further facilitated.
