As shown in FIG. 9, the main body (1) has a substantially rectangular tube shape and has an opening groove (7) having a constant width, and the opening groove (7) is the main body (1).
It extends along one side in the length direction. Therefore, the electric wire (8) of the lighting fixture (6) can be inserted through the opening groove (7). The electric wire (8) can be held by the holder (9) of the main body (1).

Further, as shown in FIGS. 10, 11 and 12, the metal fitting (10) is inserted into the opening groove (7) and engaged with both side edges (11) of the metal fitting so that both side edges (11) are engaged with each other. It is sandwiched between (10) and the retainer (12). Then, the lighting fixture (6) can be attached and supported by the bolt (13) and the nut (14) of the metal fitting (10). After that, as shown in FIG. 13, the opening groove (7) of the main body (1) is covered with the cover (16), and the main body (1) and the cover (16) are fixed by the metal fittings (17).

The junction box (2) is for relaying or connecting the electric wire (8) of the main body (1). As shown in FIG. 14, the junction box (2) has a peripheral wall (18) and a bottom wall (1).
9) and socket part (20), the socket part (20) is
Junction box with a shape corresponding to (1)
It is provided on the peripheral wall (18) of (2) and projects to the outside.
Further, at the position of the socket portion (20), a notch (21) having a corresponding width is formed on the peripheral wall (1) of the junction box (2).
It is formed in 8). Then, the tip of the main body (1) is connected to the socket portion (20) of the junction box (2).
Normally, the socket (20) is inserted into the body (1) and the screw (2
2) is screwed onto the bottom wall of the socket part (20) and pressed against the bottom wall (23) of the main body (1), and the socket part is secured by the screw (22).
(20) and body (1) are pushed apart. Therefore, the socket part (20) comes into contact with both side edges (11) of the opening groove (7) and is pressed against this. Therefore, the body (1) and the socket portion (20) can be connected and fixed by the screw (22).

Therefore, pass the electric wire (8) of the main body (1) through the notch (21) of the junction box (2),
The electric wire (8) of the main body (1) can be relayed or connected by (2). After that, the opening of the junction box (2) is covered with the cover (24). Usually, as shown in FIG. 15, cover the opening of the junction box (2) (24).
When covered with, body (1) and junction box
The covers (16) and (24) of (2) are arranged substantially in the same plane. The peripheral wall (18) of the junction box (2) has a constant height, and its bottom wall (19) projects above the bottom wall (23) of the main body (1).

Therefore, for this raceway, the covers (16), (2
When 4) is removed from the body (1) and the junction box (2), the electric wire (8) can be maintained and inspected through the opening groove (7) of the body (1) and the opening of the junction box (2). Further, the lighting fixture (6) can be attached at any position as long as the main body (1) is arranged. When changing the position of the machine on the line at the factory, the luminaire (6) can be moved to that position and relocated. For the wire (8), open it in the opening groove (7).
It can be removed from and inserted into. Therefore, the entire raceway is bolted (4) and metal fittings (5).
No need to remove from. It is easy to replenish the electric wire (8) of the main body (1) and add the lighting fixture (6). Therefore, its usefulness is extremely large. At present, it can be said that this is indispensable for electrical installation work.

By the way, this raceway was originally developed for buildings with high ceilings. In the case of a building with a high ceiling, the body (1) is attached by bolts (4) and metal fittings (5).
By hanging, the main body (1) and the lighting fixture (6) can be held at any height regardless of the height of the ceiling. However, on the other hand, there has been a problem with this equipment system.

For example, in the case of a building with a low ceiling, if the main body (1) is suspended by the bolts (4) and the metal fittings (5), the main body (1) and the luminaire (6) may be too low, which is not suitable. Therefore, even though I know that the usefulness of this raceway is remarkable, it cannot be used for low-rise buildings, and its use is limited. For use in a building with a low ceiling, it is preferable to attach the main body (1) directly to the ceiling of the building rather than suspending it from the ceiling of the building.

Therefore, the present invention solves the above-mentioned conventional problems in an electric wire raceway in which the tip of a main body having an opening groove extending in the lengthwise direction along one side surface is connected to a socket portion of a junction box. In addition to hanging the main body from the ceiling of the building, the main body can be directly attached to the ceiling, and the purpose thereof can be greatly expanded.
