[0008] Locking pieces 3 made of stainless steel are fixedly mounted on the distal ends of the horizontal plates 2a of the receiving frames 2 on both sides. Each locking piece 3 has a bottom plate 3a and a rising plate 3b.
And a top plate portion 3c bent in a hook shape. The locking piece 3 is opposed to the rising plate 2b of the receiving frame 2 at a sufficient interval by overlapping and welding the bottom plate 3a to the lower surface on the distal end side of the horizontal plate 2a of the receiving frame 2. It is fixed to. As shown in FIG. 3, two locking pieces 3 are provided on each of the receiving frames 2 so as to be separated from the both ends in the longitudinal direction.

A lid 4 is provided between the two receiving frames 2 so as to be fitted from above. The lid 4 is also made of stainless steel and has a rectangular top plate portion 4a as shown in FIG. 3, and a hanging plate portion 4b projecting downward from both side edges of the top plate portion 4a over the entire length. ing. As shown in FIG. 1 and FIG. 2, the hanging plate portions 4 b on both sides are of a leg plate shape in which the lower end 4 c is bent in an L-shape. This hanging plate part 4
The lower end 4c of b is in contact with the upper surface of the horizontal plate 2a of the receiving frame 2 when the lid is closed.

In addition, as shown in FIG. 3, a large number of slits 4 for drainage or the like are
d is formed, and a pull hole 4e is formed one by one in a portion on both sides in the middle in the longitudinal direction.

In the lid mounting structure having the above-described structure, if the lid 4 is placed on the horizontal plate portion 2a of the receiving frame 2 fixed to both side edges of the upper end opening 1 of the floor pit or the side groove, the lid 4 The lower end 4c of the both-side hanging plate portion 4b is the horizontal plate portion 2 of the both-side receiving frame 2.
Thus, the cover 4 is brought into a closed state by contacting the upper surface a, and the hinge 4 is not used unlike the related art, so that the cover 4 can be easily attached and has a simple structure.

Also, the pull hole 4 of the lid 4 in the closed state.
e, by inserting a hook or directly inserting a finger, and pulling the lid 4 up or down to one of the left and right sides to perform an upright rotation operation, the horizontal plate portion of the receiving frame 2 on one side thereof. The lower end 4c of the hanging plate portion 4b of the lid 4 slides on the upper surface 2a, and the lower end 4c of the hanging plate portion 4b of the lid 4 is placed on the back surface of the top plate portion 3c of the locking piece 3 as shown by a virtual line in FIG. The top plate portion 4a of the lid 4 is fixed to the rising portion 2 of the receiving frame 2 on one side.
