Table N4 consists of floor finishing materials such as carpets. A floor wiring device 6 is buried in the finishing layer 3 with its upper surface substantially flush with the floor surface 5. The floor wiring device 6 is installed on the upper surface 7 of the base layer 2 as an installation surface before forming the finishing layer 3, and supports the wiring storage duct 8 and the duct 8 on the upper surface 7 of the base layer 2. A plurality of first and second support members 9. , 92.

As clearly shown in FIGS. 3 to 7, especially FIGS. 5 and 5A, the wiring storage duct 8 includes an aluminum alloy channel-shaped duct body 11 having an upward opening 10, and an opening 1.
The opening 10 includes an aluminum alloy cover plate 12 that can be attached and detached to open and close the opening. The duct body 11 is manufactured by extrusion processing,
At the top of both side walls 13, a ■-shaped groove l4 for fixing the supporting member is formed, which extends in the longitudinal direction of the duct body 11 and faces the outside of the duct body 11. direction and extends inward of the duct body 11? A protruding V-shaped protrusion 15 for fixing the cover plate is formed, respectively.

Mounting tables l6 extending in the longitudinal direction of the duct main body 1l and protruding outward from the duct main body 1l are arranged on the upper edges of both side walls 13, and each mounting table I6 is provided with a protruding strip l7 protruding from its upper surface. It is divided into an inner lid plate placement section 16a and an outer surface layer a placement section 16b.

On the bottom wall l8 of the duct body 1l, a separator 19 extending in the longitudinal direction of the duct body l1 is erected at the center of the inner surface, and the separator 9 allows the inside of the duct body 11 to be connected to high current electric wires w, such as power lines. The first used for storage
Wiring path 20, and low current electric wires such as signal lines and telephone lines w2
It is divided into a second wiring path 20 and a second wiring path 20, which is used for storing.

The separator 19 has a retaining groove 21 extending along the upper end thereof, and the inner circumferential surface of the retaining groove 21 is formed in a substantially arc-shaped cross section. A round rod-shaped rubber buffer member 22 is fitted into the holding groove 21 .

When the duct main body l1 is manufactured by extrusion processing in this manner, its structure is simplified, and the manufacturing man-hours and manufacturing costs are significantly reduced.

The cover plate l2 is also manufactured by extrusion processing, and has engaging claws on both sides of its lower surface that extend over the entire length of the cover plate l2 in the longitudinal direction and elastically engage and disengage from the double-sided protrusions 15 of the duct body l1. 23 are provided respectively. In the illustrated example, each engagement claw 23
consists of a base end a that extends downward from the lower surfaces of both sides of the cover plate l2, and a v-shaped retaining part b that is suspended from the lower end of the base end a and projects outward. The distance between the tips of both retaining parts b is
The spacing between the tips of both protrusions 15 of the duct body 11 is set slightly wider, so that when the opening 10 of the duct body l1 is closed by the cover plate I2, each engaging portion b is After getting over the top C, the upward slope d1 of each engaging portion b engages with the downward slope d2 of each protrusion 15.

In this engaged state, both sides of the lower surface of the lid plate 12 are placed on both mounting portions 16a of the duct body 1l, and the central portion of the lower surface abuts against the buffer member 22.
