The insertion members 66a and 66b are inserted into the insertion holes 73 formed in the top plate 3 so as to be fixed to the top plate 3.

The operation of the OA desk configured as described above will be described below mainly with reference to FIGS. 5 (a) and 5 (b).

FIG. 7A shows a state in which the upper leg is moved vertically upward.

Depending on the seated posture or the three-dimensional posture,
When it is determined that the height from the floor surface is not appropriate, the handle 23 provided on the lower leg 8 is rotated to either direction. The top plate 3 can be adjusted to an arbitrary height via the moving function unit 70 only by this simple operation. After setting the height of the top plate 3 at an appropriate position in this way, the angle of the top plate 3 is adjusted. For this adjustment, the knob 47 described above is pulled to move the insertion pieces 50L and 50R to the inclination angle holding members 35R and 35R.
The cutout portions 49, 49 formed in L are removed.
Then, the top plate 3 receives the urging force of the urging member 29 and can rotate upward about the fulcrums 28R and 28L.
In this way, the operator urges part of the top plate 3 downward so as to have an appropriate angle, and when the angle becomes an arbitrary angle, the knob 4 is pressed.
Release 7. Then, the insertion pieces 50R, 50L are fitted in the coil springs 56R, 5 in either of the notches 49, 49 facing each other.
It is inserted by the action of 6L and the top plate 3 is securely fixed at an arbitrary angle. And it is the knob 47 that restores the inclination.
While pulling, push the top plate from above.

Next, the top plate 3 is slid and adjusted. This adjustment is

From the notches 38, 38 formed in the center of the
Remove the R and 40L. In this state, the top plate 3 or a part of the top plate supporting member 26 is held and slid to an appropriate position. Then, the knob 39 is released at an arbitrary position.
Then, the insertion pieces 40R and 40L are coil springs 48R and 4L in the notches 38 and 38, which are the positions facing the insertion pieces 40R and 40L.
It is inserted by the action of 8L and is securely fixed at the slide position.

As described above, according to the present invention, each part can be adjusted very easily, and as described above, the height of the top plate from the floor, the inclination angle, and the slide can be adjusted independently. Therefore, workability can be significantly improved. Further, the position of the knob, which is considered to be frequently used, is arranged on the side of the top end of the operator who is seated, so that the operator can easily perform the adjustment without causing unnecessary operation. . Further, since it is surely fixed at each inclination angle and each slide position, it is possible to prevent the operator from having to adjust the inclination angle and slide position again even if the operator carelessly adds weight.

Further, the shaping member described above is attached to the end surface portion of the top plate which is adjustable as described above. Because of this, steps and gaps are prevented from occurring, so that the steps do not come into contact with the worker's hand or arm, and there is no discomfort and no obstacle to the work. For example, it is possible to prevent the slag of the eraser from being accumulated or clogged in the gap.
Furthermore, since a soft molded member is used especially for the seated end of the worker, a soft feeling can be given to the hand or arm at the time of work, and a comfortable contact feeling can be given.

By the way, the shaping member can be manufactured by extrusion molding from the above-described configuration. Therefore, it is possible to realize a significant reduction in manufacturing cost as compared with the conventional injection method, and it is possible to omit the mold that has to be prepared according to the size of the top plate, which has been conventionally required. In addition, the fitting portion formed on each is formed in a portion that does not appear in the appearance at the time of fitting, and by fitting in the thickness direction of the top plate, it is possible to regulate the dimensional error of the synthetic resin that occurs during manufacturing, You can always maintain stable quality without spoiling the aesthetics. Furthermore, the inner fitting member of the shaping member is adhered to the end surface of the top plate with, for example, an adhesive and screwed. However, in the present embodiment, the screw of the inner fitting portion is not attached with the outer fitting member. Since it can be stopped from the outside,
Assembling work can be facilitated. Conventionally, this work has been performed by screwing from the inside of the top plate while pressing the shaping member against the end surface of the top plate. From this, the structure of the top plate was also restricted, but this problem can be solved by the shaping member having the illustrated structure.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the gist thereof.

[Advantages of the Invention] According to the present invention described in detail above, when the top plate is moved vertically or inclined with respect to the horizontal plane, the top plate is slid in the front-back direction with respect to the seating end by the slide mechanism portion. As a result, the top plate can be set at the position where the operator can most easily operate, and it is possible to provide the OA desk which can surely improve the workability.
