The wiring duct 1 and the floor panel 3 are covered with the carpet 4, but the power line, telephone line, and signal line are pulled out as flat cables from the flat cable outlet lower 0°71.72 and connected between the carpet 4 and the floor panel 3. The wiring can be routed to the desired position, so the wiring is not exposed on the carpet, improving the aesthetic appearance.

Furthermore, the movable outlet 43 has its outlet body 46
Since it is possible to switch between a state in which the duct protrudes upward from the lid 6 and a state in which it is stored in the duct body 5, the aesthetic appearance of the floor is improved when the duct is stored.

The opening 7 is punched out by punching out the knockout part 74 provided in the bottom plate 9.
5, it is also possible to connect the electric conduit 76 to each passageway 35, 36, 39.

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 short circuit, and
Damage to the power line sheathing can also be prevented.
