As shown in FIG.
The mounting portion 19 is composed of a sliding surface 19A, an engaging convex portion 19B, and a locking piece 19C. The engaging piece 19C is engaged with the vertical guide groove G of the inclined wall portion 12, and the engaging piece 19C is engaged with the bent portion 14, which is the edge portion of the post 1. As shown in FIG.

After attaching the wire sway stopper K to the post 1 as indicated by the arrow in FIG. 8, as shown in FIG. Attachment of the post cover J is completed by locking.

According to the wiring structure of the post 1 using such a wire jolt stopper K, the wire jolt stopper K detachable from the post 1 has locking portions 21, 21 for locking the post cover J. As shown in FIG.
As a result, the wire C is vertically inserted into the inner space A of the post 1 in a state in which the wire stopper K and the cover J are removed from the post 1, and the wire stopper K is attached to the post 1. After that, the post cover J is locked to the locking portions 21, 21 of the wiring runaway stopper K. As shown in FIG.
Alternatively, after the wiring C is vertically inserted into the internal space A of the post 1 in a state where the wiring stopper K is attached to the post 1 and the post cover J is removed, the wiring stopper K is engaged. The post cover J is locked to the stop portions 21 , 21 .

By engaging the post cover J with the portions 21, 21, the opening I of the post 1 can be easily covered with the post cover J.
Therefore, it is possible to simplify the wiring processing work of inserting the wiring C into the internal space A of the post 1 in the vertical direction and putting the wiring C together.

In addition, since the post cover J is attached to the wiring runaway stopper K attached to the post 1, the thickness of the post cover J can be reduced compared to a structure in which the post cover J is directly attached to the post 1 by an attachment member provided on the post cover J. The thickness can be reduced, and the post cover J can be formed only from, for example, an aluminum alloy or the like.
Therefore, when storing or transporting the post covers J, J, .

8, the outward movement restricting portion 20 has an arch shape in a plan view, and has an arch shape protruding from both ends near the attachment portions 19, 19, as shown in FIG. The thickness T gradually decreases toward the center H.
Therefore, the arch-shaped outward movement restricting portion 20 is likely to be elastically deformed in a direction (inward in the width direction) in which the both ends are brought closer.
Therefore, while the arch-shaped outward movement restricting part 20 is easily elastically deformed, the wire sway stopper K can be easily attached to the post 1 with one action, so that the wire sway stopper K is attached to the post 1.例文帳に追加Work efficiency can be improved.

Further, in the wiring runaway prevention tool K, the left and right sliding surfaces 19A, 19A are in surface contact with the left and right inclined wall portions 12, 12 of the post 1, and the left and right engaging convex portions 19B, 19B It is attached to the post 1 in a state in which it is engaged with the directional guide grooves G, G and the left and right locking pieces 19C, 19C are locked to the left and right bent portions 14, 14 of the post 1.
