Abstract

PROBLEM TO BE SOLVED: To form a wiring space for a crossfeed between front and rear top plates by protrusively arranging connecting members thinner than the front top plate in a rear end lower part of the front top plate, and connecting the rear top plate so as to become an equal height as the front top plate. SOLUTION: Respective connecting members 9 and 10 have side surface view upward U-shaped base parts 21 whose central part is recessed so as to become thinner than a thickness of a front top plate 5. Protrusive levers 22 of the respective connecting members 9 and 10 are fitted to inserting holes 15' and 15, and front walls 21a of the base parts 21 are brought into close contact with a vertical piece 23a of an edge material 23, and the front walls 21a are inserted into through holes 16', and are fixed to a rear surface of the front top plate 5 by set secrews screw-fitted to screw holes 16. The tips of the respective protrusive levers 22 are also fixed to front pieces 14a of reinforcing members 14, and rear end parts of the base parts 21 are fitted to a joining member 19 in a rear top plate 8, and are fixed by set screws. Therefore, the rear top plate 8 is firmly joined to the front top plate 5 so that its upper surface becomes an equal height as an upper surface of the front top plate 5. In this way, a wiring space 6 for a crossfeed is formed above the base parts 21 between both top plates 5 and 8.

【The invention's effect】

(a) According to the first aspect of the present invention, by connecting the front top plate and the rear top plate with a connecting member thinner than the thickness of the front top plate, the distance between the front top plate and the rear top plate is reduced. Since the wiring space for horizontal feed is formed in the top, the horizontal feed can be performed simply by attaching the top plate to the top plate support such as legs and sleeve boxes, and the positional relationship with other members. Dimensional accuracy of the upper end opening of the wiring space can be obtained without taking into account the above, and there is little possibility that dimensional deviation will occur when a cover or the like is attached to that portion. Further, since a space serving as a wiring duct is incorporated in the top plate itself, there is no need to separately attach the wiring duct to a support such as a leg, so that it is easy to assemble a desk or the like, and the appearance is good.

(B) According to the second aspect of the present invention, a space for vertical feeding continuous with the wiring space for horizontal feeding can be formed easily and in good shape at an arbitrary position.
