DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments.
In FIG. 1, reference numeral 1 denotes a lighting bureau according to the present invention. The lighting bureau 1 includes a leg body 2 in which a user's foot is located, a desk body 3 having a door top plate 30 detachably connected to the leg body 2 and being openable and closable in the front, and a desk body. The storage unit main body 4 is detachably connected to the upper part of the storage unit 3 in a detachable manner in the vertical direction.

The leg body 2 includes left and right leg side plates 21, 21.
It is composed of a rear curtain plate 23 which is detachably connected between the rear end portions of the left and right leg side plates 21, 21. The rear curtain plate 23 is formed in a rectangular plate shape, and head-engagement engagement members 5, 5 are attached to the upper and lower ends of the left and right end surfaces so as to protrude outward (toward the left and right leg side plates 21, 21). The head-engaged engagement tool 5 is screwed to the rear curtain plate 23 and a regulating flange 52 that abuts the left and right end surfaces of the rear curtain plate 23 to regulate the protruding state of the head-engaged engagement tool 5. A fitting shaft 53 having a diameter smaller than that of the regulating flange 52, which is located outside the regulating flange 52, and a fitting shaft 5 located outside of the fitting shaft 53.
It is composed of a head 54 having a diameter larger than three.

Since the left and right leg side plates 21 are formed in the same shape facing each other, only the right leg side plate 21 will be described. The right leg side plate 21 is formed in a plate shape having a small depth at an upper portion, and is provided at an upper and lower end portion of an inner surface of a rear end portion with an engagement metal fitting 6 corresponding to the headed engagement tool 5 of the rear curtain plate 23. 6 is provided, and the headed engaging tool 5 is provided on the upper surface of the rear end portion so as to protrude upward. The engagement fitting 6 has a semicircular upper portion, and has a head 54 of the engagement fitting 5 with a head and an insertion / removal portion 61 having a diameter larger than that of the regulating flange 52.
And an engagement hole 60 formed by an engagement portion 62 having a diameter smaller than that of the head 54 and the regulating flange 52 into which the insertion shaft 53 of the engagement member 5 with the head is continuously inserted below the insertion / removal portion 61. And an inclined guide portion 63 which is deeper in the direction opposite to the rear curtain plate 23 in the direction of the engaging portion 62 from the insertion / removal portion 61 and has an engaging hole 60 formed therein. Steps 65, 65, and mounting projections 66, 66 having mounting holes 64, 64. The steps 65 are formed such that the mounting screws 641, 641 do not hinder the connection with the rear curtain plate 23 when the fitting 6 is mounted on the leg side plate 21.

In the right leg side plate 21 where the engagement fitting 6 is attached, the movement of the head 54 of the headed engagement tool 5 is hindered when the rear curtain plate 23 and the right side plate 21 are connected. The mounting recesses 67 and the mounting steps 671, 671 are formed so that the mounting screws 641, 641 do not contact the rear curtain plate 23. On the other hand, on the upper surface of the front end portion of the right leg side plate 21, the front portion protrudes forward to the extent that the upper surface does not protrude above the right side plate 21, an insertion hole 71 is formed in the front end portion, and mounting screws 721, 721 are formed in the rear portion. The connection fitting 7 in which the mounting holes 72 are formed is mounted. The rear curtain plate 23 of the desk body and the left and right leg side plates 21 and 21 are configured as described above, and are connected as follows.
