<Beam>
As shown in FIG. 4, the beam 14 is a so-called cross beam member, and has a function of ensuring the strength of the desk body 1 by connecting the left and right legs to each other. Further, in the connecting desk 100, the duct 10 is formed by the pair of beams 14 facing each other. The beam 14 is formed to have a substantially rectangular parallelepiped outer shape by combining a plurality of members obtained by bending a sheet metal material. FIG. 7 is a diagram showing the beam 14. As shown in FIG. 7, the beam 14 mainly has a beam main body 141 for connecting the legs to each other, and a reinforcing body 142 provided inside the beam main body 141 to reinforce the beam main body 141. The beam body 141 is formed by bending a sheet metal material in a plurality of horizontal directions to have a substantially rectangular parallelepiped outer shape. Specifically, the beam body 141 includes a base wall 1411 extending in the left-right direction, a pair of facing upper end walls 1413 and a lower end wall 1414 extending backward from the upper end edge and the lower end edge of the base wall 1411. It has rear end walls 1412, 1412 that face the base wall 1411 and extend so as to approach each other from the rear end edges of the upper end wall 1413 and the lower end wall 1414. An opening 143 is formed between the rear end walls 1412 and 1412. The beam body 141 is connected to the leg at its side end.

The reinforcing body 142 is formed by bending the sheet metal material a plurality of times in the horizontal direction, and forms a substantially U shape in which both ends are connected to the base wall 1411 in a cross-sectional view. More specifically, the reinforcing body 142 extends downward from the rear surface of the base wall 1411 by bending the upper horizontal wall 1421 extending backward in parallel with the horizontal plane and the upper horizontal wall 1421 at a right angle. It has a 1423 and a lower horizontal wall 1422 that extends forward parallel to the horizontal plane and is connected to the base wall 1411 by further bending the vertical wall 1423 at a right angle. The base wall 1411 is an example of the "standing wall" in the present invention. The reinforcing body 142 is provided near the center of the base wall 1411 in the vertical direction, and extends from the vicinity of the left end to the vicinity of the right end of the base wall 1411 in the left-right direction. The reinforcing body 142 ensures the strength of the beam 14 as a beam member. The reinforcing body 142 is also called a flange. The reinforcing body 142 is an example of the "protruding portion" in the present invention.

As shown in FIG. 4, in the desk body 1 according to the present embodiment, the legs are connected to each other by two beams 14 and 14 having different lengths in the left-right direction. The two beams 14 and 14 are designated as the beam 14a and the beam 14b in order from the right side of the desk body 1. The beam 14b is a beam 14a shortened in the left-right direction, and both have the same structure. The lengths of the beam 14a and the beam 14b in the left-right direction correspond to the lengths of the top plate panel P11 and the top plate panel P12 in the left-right direction, respectively. However, the length of the beam 14 in the left-right direction can be changed as appropriate. The beam 14a connects the end leg 12a and the intermediate leg 13, and the beam 14b connects the intermediate leg 13 and the end leg 12b. As a result, the left side surface of the end leg 12a and the right side surface of the second vertical member 132b constituting the intermediate leg 13 are connected by the beam 14a, and the second vertical member 132b constituting the intermediate leg 13 is connected by the beam 14b. The left side surface of the end leg 12b is connected to the right side surface of the end leg 12b. Any method can be used for the connection between the beam 14 and the leg body. The beams 14a and 14b are connected in the front-rear direction so that the rear end surface, that is, the rear surface of the rear end wall 1412 is substantially aligned with the rear end surface of the second vertical member 132b constituting the intermediate leg body 13. Since the position of the rear end surface of the second vertical member 132b in the front-rear direction substantially coincides with the position of the rear end surface of the top plate 11, the position of the rear end surface of the beam 14 and the rear end surface of the top plate 11 in the front-rear direction. The positions are almost the same. As a result, the beam 14 is offset forward with respect to the rear end surface of the first vertical member 131b. Further, a gap is formed between the upper end surface of the beam 14 and the lower surface of the top plate 11.

As shown in FIG. 1, the desk body 1B is a front-back symmetry of the desk body 1A. The connected desk 100 is a connection between the desk body 1A and the desk body 1B.
