【The invention's effect】

(a) According to the first aspect of the present invention, when the engaging projection of the engaging claw provided on the lower surface of the cover engages with the horizontal groove of the L-shaped engaging groove, the cover is prevented from ascending. Even if a large upward pulling force acts on the cover, the cover does not easily come off. In addition, the cover can be easily mounted simply by placing the cover on the opening such that the engagement protrusion falls into the downward groove of the engagement groove, and then sliding the cover in the direction of the horizontal groove. The cover can be easily removed from the opening by the reverse operation. Further, the engaging claws are provided on the lower surface of the cover, and when the cover is attached to the opening, the engaging claws are not exposed to the outside, so that the appearance is good.

(B) As in the second aspect of the present invention, when an outlet whose insertion port faces upward is attached to the cover, a power supply plug of the electric device placed on the top plate is inserted into this outlet. This is convenient because a power supply plug of an electric device can be inserted into this outlet to easily supply power to the electric device. In addition, when the outlet is provided in the cover in this manner, a large peeling force acts on the cover when the plug is pulled out, whereas the present invention has the same effect as the above (a). This is particularly significant when an outlet is provided.

(C) When the cover is provided with a detachable wiring cap as in the third aspect of the present invention, only the wiring cap of the insertion part of the wiring cords is separated from the cover, and the other part of the opening is covered. And can be used in a good format.

(D) When the upper edge of the horizontal groove is slightly inclined forward and downward as in the fourth aspect of the present invention, the more the engagement protrusion is advanced toward the tip of this horizontal groove, the more the engagement is made. The engagement between the mating projection and the engagement groove is tight, so that the vertical play of the cover can be prevented, and the engagement projection can be prevented from coming off rearward.
