The panel-side bracket is formed in a U-shape in a flat cross section that enters the desk-side bracket and opens toward the desk-side bracket. In the side plate of the panel side bracket, an engagement groove that is dropped and fitted into the support pin of the desk side bracket is cut open.

  The desk according to the invention of claim 4 is the desk according to claim 1, wherein the vertical portion of the desk-side bracket that overlaps the panels is formed in a U-shape in a flat cross section that opens toward the opposite side of the panels. In the vertical part of the desk side bracket, a plurality of engagement holes opened toward the panels are formed at appropriate intervals in the vertical direction, while the panels are dropped into the engagement holes and engaged. The engaging body is projected forward, and the panel is held so as not to move upward by bringing the stopper means into contact with the engaging body from above.

  A desk according to a fifth aspect of the present invention is the desk according to any one of the first to fourth aspects, wherein the desk-side bracket is fixed by clamping to a horizontally long beam disposed horizontally below the top plate. Yes.

  According to the present invention, since the desk-side bracket extends below the top plate, even the back panel extending above and below the top plate can be attached without any trouble. In addition, there is no need to process holes such as the back of the legs or the back of the top board, so there are no cases where the holes are exposed and the appearance is not impaired without the panels attached. It is.

  In addition, for example, by fixing the panel side brackets to the panels via spacers, the front and rear positions of the panels can be easily changed.For example, the back panel is brought into close contact with the back of the top board or legs, It is also easy to arrange the wiring space between the legs and the back of the legs. The front and rear positions of the curtain can be easily changed.

  Further, since the panels are not attached to the legs, the horizontal width can be freely set.

  According to the second aspect of the present invention, the panels can be attached / detached with one touch, and the panels are held in a non-detachable manner by the stopper means, so that an upward external force is applied for some reason. However, the panels will not fall off. That is, the panels can be held in a stable state without impairing the ease of attachment / removal.

  Furthermore, if it comprises like Claim 3, since a panel side bracket is hidden behind a desk side bracket and cannot be seen, there exists an advantage which can improve aesthetics remarkably. According to the fourth aspect of the present invention, the panel has only to be provided with an engaging body so that the structure can be simplified.

  Further, since the desk-side bracket is detachably attached to the beam according to the fifth aspect of the present invention, it is very easy to change between the desk without the panels attached and the desk with the panels attached (that is, as an optional panel type).

  There are two types of desks with two backs spread at an angle of 120 ° in plan view. When three such desks are arranged back to back, three back panels 5 are arranged in three directions at intervals of 120 ° in plan view. It becomes an extended form. In this case, a corner post 71 having a regular triangle in plan view may be used as shown in FIG.

  When the back panels 5 arranged in a cross shape or a T shape in plan view are connected to each other, the corner post 71 is not necessarily used, and a connecting body 75 as shown in FIG. 24 can be used. The connecting body 75 has a configuration in which the long plate portion 75a and the short plate portion 75b intersect each other, and a flange portion 75c is provided at the tip of each plate portion 75a, 75b.

  And the notch 76 is provided in the site | part close | similar to a crossing location among the longitudinal plate parts 75a so that the longitudinal plate part 75a can be broken as shown to (C). When the three back panels 5 are connected in a T shape in plan view, they may be broken as shown in FIG.
