てＬ・た。As shown in Japanese Utility Model Publication No. 45-22442, a conventional trough has a gutter-shaped main body and a lid, which are slightly narrowed at one end to form a fitting part, and are joined together in the L direction. When installing, attach the H-type connectors prepared in advance to both sides of the main body.
The side edge of the lid was inserted into the groove opened above the H-shaped connector to form an L-shaped connector.

隙間を生じる欠点があった。However, with this method, the connector cannot be attached to the fitting part of the main body that has a step, and it is difficult to assemble the part where the fitting part of the main body and the lid overlap, which is adjacent to the opposite end. Therefore, there was a drawback that a gap was created at the joint after assembly between the lid of the connecting body notch and both side edges of the main body to allow air to flow freely.
本発明は、このような欠点を改良すると同時に従来のも

たものである。In the present invention, a trough body with a constant cross section is joined together in a tunnel to form a long gutter shape, and after installing a power transmission cable and other necessary parts inside, a g-thick valve is formed by narrowing it at one end. When closing a gutter-like lid of approximately the same width and having a fitting part, grooves with a constant cross section with steps are provided in advance at the tips of both side edges of the main body, and the side edges of the lid have a deep L-shaped groove. Further, by repeating the operation of inserting the side edge of the fitting portion of the lid into the shallower groove and successively adjoining the lid, workability and airtightness are greatly improved.
本発明を添附図面によって更に具体的に説明する。The present invention will be explained in more detail with reference to the accompanying drawings.
