are drilled, and a plurality of screw members 92 are inserted into each hole 9.
By screwing into 1, floor panel 3 connects to joist 8.
Fixed above 0.

Moreover, when fixed on the joist 80, the floor panel 3 is flush with the top surface of the wiring duct 1,
The end of the floor panel 3 is received by the support protrusion 14 of the duct body 5. Moreover, the floor panel 3 is screwed and fixed to the support protrusion 14 by screw members 98.

The carpet 4 is laid over the wiring duct 1 and the floor panel 3, and an opening (not shown) is provided in a portion corresponding to the movable outlet 43 to allow the movable outlet 43 to protrude.

Next, the operation of this embodiment will be explained. The wiring duct 1 is laid along the wiring route on the base 2 while adjusting the height with the support bundle 7. Further, on the base 2 between the wiring ducts 1, a plurality of joists 80 are arranged, the height of which is adjusted by a joist support bundle 81, and the wiring ducts 1 are placed on these joists 80.
The floor panel 3 is fixed so as to be flush with the upper surface of the floor panel 3. Therefore, floor panel 3 has joists 8
0 and the joist support bundle 81, it is fixed on the base 2 and also on the duct body 5, and the floor panel 3 and the duct body 5 are firmly integrated, so that earthquakes etc. Even if it gets hot, the floor panel 3 will not fall from above the joist 80.

Furthermore, since the support bundle 7 supports the bottoms of both sides of the duct body 5, the support bundle 7 does not interfere with the facility of the floor panel 3. Further, the adjustment bolt 20 of the support bundle 7 is connected to the auxiliary track 40 on the inner plate portion 11.
Since the adjusting bolt 20 protrudes into the duct main body 5 at a section separated from the adjusting bolt 20, there is no possibility that the power line or the like will be damaged by the adjusting bolt 20.

Furthermore, the support plate part 13 that receives the lid 6 is connected to the inner plate part 11.
Since the shape is such that the receiving frame 8 is reinforced, the strength of the receiving frame 8 is improved.

When the lid 6 is opened, the support plate portion 13 of the receiving frame 8
The adjustment bolt 20 can be rotated by inserting a screwdriver or the like through adjustment holes 28 and 29 provided in the receiving member 15, and the height of the wiring duct 1 can be adjusted extremely easily.

The carpet 4 covers the wiring duct 1 and the floor panel 3, but the power line, telephone line and signal line are connected to the flat cable outlet 7 as flat cables.
0, 71, and 72, and the wiring can be routed to a desired position between the carpet 4 and the floor panel 3. Therefore, the wiring is not exposed on the carpet, and the appearance is improved.

Furthermore, the movable outlet 43 can be switched between a state in which the outlet body 46 protrudes upward from the lid 6 and a state in which it is housed within the duct body 5, so that the aesthetic appearance of the floor is improved when the movable outlet 43 is housed.

By punching out the knock-out portion 74 provided on the bottom plate 9 to form an opening 75, each passageway 35, 3
6, 39 can also be connected to the electric conduit 76.

Since the auxiliary line 40 is separated from the power line passageway 39 via the separator 38, connecting the power line with the auxiliary line 40 eliminates the risk of being shot and also prevents damage to the power line sheathing. can also be prevented.
