For example, in the above-described embodiment, the case where the top cover C1 and the side cover C2 use an integrally molded product having a symmetrical shape with respect to the approximate center C in the front-rear direction is illustrated and described. It is not limited. For example, as shown in FIG. 14, cover forming members C1a, C1a of a front-rear split type are provided at a substantially middle portion in the front-rear direction of the top surface 80, and the joining surfaces 110, 110 which can be overlapped with each other are provided inward. The connection surfaces 110 may be suspended from the ends so that the connection surfaces 110 and 110 can be connected by bolts 112 and nuts 113. According to this, while each cover forming member C1a can be used as a top cover of a single furniture unit U, it can also be used as a top cover for interconnecting two furniture units. When the cover forming body C1a is used as the top cover for the furniture unit U of the single desk 10, the joint surface 110 may be provided at the rear.
[0035]
Similarly, the side cover C2 is also formed as a front-rear split type cover forming member C2a, C2a at a substantially middle portion in the front-rear direction of the side surface 90, and the joining surfaces 120, 120 that can be overlapped with each other are the inner surfaces of the side surface 90. The joint surfaces 120 may be connected by bolts 121 and nuts 122. According to this, while each cover forming member C2a can be used as a side cover of a single furniture unit U, it can also be used as a side cover for connecting the two furniture units U, U. When the cover forming body C2a is used as a side cover for a single furniture unit U, it may be provided so that the joint surface 120 is located at the rear.

【The invention's effect】
As described above, according to the present invention, each furniture unit can be interconnected in a state where the front and rear furniture units are determined at positions separated by a predetermined distance.
[0037]
Further, since the first connection device has a structure including a top surface having an outer decorative surface extending along the upper connection frame, a connection area of the first connection device corresponds to a length of the upper connection frame. Thus, it is possible to keep the connection strength increased.
[0038]
Further, since the second connecting device also employs a configuration including a side surface portion having an outer decorative surface extending along the column similarly to the first connecting device, the second connecting device is as wide as the first connecting device. A connection region can be formed, and it is possible to provide a furniture unit connection structure having high rigidity by interacting with the connection of each furniture unit by the first connection device.
