Can be suitably avoided, and the degree of freedom of arrangement of the desks D1, D2, the wagon W, etc. is improved.

  The lighting device L3 shown in FIG. 10 has left and right leg bases A3 and A3 attached to the lower horizontal member 14 so that the left and right positions can be changed. If it is such, the left-right position of leg base A3, A3 can be changed suitably according to the installation location and shape of desk D1, D2. For this reason, the places where the desks D1 and D2 and the wagon W are arranged are not restrained by a general leg base mounting position. Therefore, the desks D1 and D2 can be appropriately arranged at a desired location, for example, a location suitable for receiving illumination light from the illumination device L3.

  In the present embodiment, the upper horizontal member and the lower horizontal member are in the shape of a prismatic pipe, but it is needless to say that the present invention is not limited to this mode. As an example of the other thing, the thing which set the dimension of the up-down direction in an upper horizontal member largely can be considered. For example, if the vertical dimension of the upper horizontal member is set large and it is plate-like, it can function as a panel or partition plate used on a desk that is placed face-to-face with the original function of connecting the left and right columns. Can also be given at the same time. It goes without saying that the thickness dimension of each horizontal member can also be set appropriately.

  In the present embodiment, the wiring duct is mounted on the lower horizontal member, but the wiring duct may be provided so that the height position can be changed.

  In the present embodiment, two sets of two desks facing each other (that is, four desks) are used. However, the present invention is not limited to such a mode. The present invention may be applied to an embodiment in which only one set of two desks is used, or an embodiment in which three or more sets are used.

  A plurality of wiring ducts may be provided on the support frame. In particular, when the desk does not have a groove for wiring storage, the wiring duct of the lighting device can be used, which is particularly effective. As long as the upper and lower wiring ducts are provided, for example, the lower wiring duct can be properly used for lighting equipment, and the upper wiring duct can be appropriately used for a personal computer or the like.

  It goes without saying that various shapes can be adopted as long as the shape of the wiring duct can receive wiring even if it is other than that shown in the present embodiment.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
