Filling lids filled with synthetic resin, stone materials, etc., and other rigid flat lids such as concrete plates and metal plates are also applicable.

The cover plate 25 has one end substantially aligned with the end of the rigid base lid 21, and a part of the cover plate 25 is fixed so that the cap nut 9 can be screwed into the fixing screw 8. An opening 26 is formed at a position corresponding to the screw 8 and serves as a fixed side. Then, the other end is extended and this is used as the free end. Further, a connection plate 27 having a through hole through which the fixing screw 8 is inserted is fixed to the rigid base lid 21 just below the opening 26.

The cover body 20 having such a configuration is attached to the attachment space 18 and is supported at both ends on the bottom portion 4 of the holding frame 2 and the sliding surface 13 of the bottom portion 12 of the sliding frame 10. . Then, the fixing screw 8 is inserted into the through hole of the connecting plate 27 of the rigid base lid 21 via the rubber cushion 28, and the cap nut 9 is screwed to the fixing screw 8 from the opening 26. As a result, one end of the cover body 20 is fixed to the holding frame 2 side. In this state, the free end of the cover plate 25 is attached to one floor f. Further, a sliding gap is formed between the free end of the rigid base lid 21 and the rising wall 11 of the sliding receiving frame 10 so that the sliding movement of the rigid receiving base 10 is possible.

In such a configuration, the cover plate 25 is supported by the holding frame 2 and the sliding frame 10 via the rigid base lid 21. Therefore, even if a large load is applied to the cover plate 25, the load can be supported by the rigid base lid 21, and the cover plate 25 is not damaged or curved. At this time, due to the action of the rubber cushion 28, even if an impact is applied from above, the impact noise and the like are alleviated as much as possible.

When the floors f, f move relative to each other left and right and front and back, the free end of the rigid base lid 21 slides on the sliding surface 13 of the slide receiving frame 10, and the cover plate 25 The free end of the above moves on the floor f and absorbs its relative movement without impairing the shielding of the joint s. Therefore, the joint body s is covered with the cover body 20 without difficulty.
