More specifically, it is used by being attached to a mount angle 91 or the like of an electric / electronic device storage box 9 via an attachment member 21 attached to the side surface of the cable duct 1. In order to allow the cable 71 to crawl on the cable duct 1, the duct main body 13 of the present embodiment is configured such that the arm portion 12 extends from the base portion 11 located on the back surface side toward the front surface side. As shown in FIG. 3, the arm portion 12 has a comb shape in a plan view because a plurality of portions 121 projecting forward are provided following the flat plate-shaped portion extending in the left-right direction. Further, the arm portion 12 extends from both the upper portion and the lower portion of the base portion 11, and a space is provided between the arm portions 12 so that a plurality of cables 71 can be laid. That is, the duct main body 13 of the present embodiment is provided with a space that can be wired in the horizontal direction between the pair of upper and lower arm portions 12, and is provided in the vertical direction between the plurality of protruding portions 121 arranged in the horizontal direction. There is a space where wiring is possible.

The arm portion 12 is provided in a substantially flat plate shape, and is configured so that the tip of the protruding portion 121 bulges in the left-right direction. A cover 22 is detachably attached to the tip of the arm portion 12. The cover 22 of the present embodiment is connected to a plurality of protruding portions 121, and is configured to be rotatable around the tip of the lower arm portion 12 or the upper arm portion 12. In the cable duct 1 of the present embodiment, the work can be performed in a state where the cover 22 is not attached or in a state where the cover 22 is rotated and opened, so that efficient wiring work can be maintained. Further, after the wiring work, the cover 22 makes it possible to prevent the cable 71 from popping out from the tip of the arm portion 12 and to blindfold the cable 71.

The work of wiring the cable 71 in the cable duct 1 of the embodiment is mainly performed from the tip end side of the arm portion 12. Since the hole 14 is used to pass the binding member 81 for fixing the cable 71, the work is performed around the hole 14, but in the present embodiment, the hole 14 provided in the arm 12 is tipped. The arrangement is biased to the side. If the hole 14 is arranged on the tip end side of the arm 12, the fixing work can be facilitated. Further, in such a form, for example, a LAN cable having a small allowable bending radius is arranged on the back side (base 11 side) of the arm portion 12, and is allowed on the tip end side of the arm portion 12. It becomes easier to assign an arrangement such as arranging an optical cable having a bending radius larger than that of a LAN run cable or the like.

As shown in FIG. 4, the cable duct 1 of the present embodiment is provided with a plurality of holes 14 in the arm portion 12, and the cable 71 can freely move between the holes 14 and the holes 14. A holding unit 15 for suppressing this is provided. When such a holding portion 15 is provided between the holes 14, it is possible to improve workability when fixing the cable 71 with the binding member 81. Further, the holding portion 15 of the present embodiment can be held so that the cable 71 extends in the width direction of the arm portion 12. Therefore, the cable 71 can be wired so as to be substantially orthogonal to the longitudinal direction of the protruding portion 121 of the arm portion 12, and it becomes easy to secure the depth of the space that does not hold the cable 71. In this form, the cable 71 is wired along the width direction of the arm portion 12.

The holding portion 15 of the present embodiment is provided as a concave recess. This recess extends in the width direction of the arm portion 12, and is configured as a recess extending from one end side to the other end side of the protruding portion 121 of the arm portion 12. In this way, since the holding portion 15 is provided so as to be recessed from the adjacent surface, it is possible to suppress the space in the cable duct 1 from being compressed by the holding portion 15 and to secure a wide wiring space. .. Further, it is not necessary to separately install a member dedicated to holding the cable in the device or the cable duct 1.

The holding portion 15 is provided with a surface having an arcuate cross-sectional view as a concave portion, and the surface on the back side of the portion where the surface is provided is formed to be curved in a convex shape as shown in FIG. It is configured to have an arcuate surface in cross section. With such a form, the thickness of the holding portion 15 is kept substantially uniform, and the binding member 81 is prevented from protruding significantly in the thickness direction of the arm portion 12.

Further, the holding portion 15 of the present embodiment is provided so that the surface on the back side of the portion where the concave recess is provided is dented from the surrounding portion connected to the portion. Therefore, as shown in FIGS. 6 and 7, even when the binding member 81 is wound around the holding portion 15, it is possible to prevent the binding member 81 from protruding significantly in the thickness direction of the arm portion 12. .. Therefore, it becomes easy to secure the equipment installation space and the wiring space.

By the way, some optical cables 71 are provided with a branch portion 73 that covers the core wires to prevent their exposure at the locations where the plurality of core wires provided in the coating are branched. As shown in FIG. 6, the branch portion 73 is provided with each core wire covered. In addition, such a branch portion 73 is also called a dam or the like.

The branch portion 73 of the optical cable 71 of the present embodiment has a diameter larger than that of the surrounding portion, but the recess of the present embodiment is provided so as to be able to hold the branch portion 73. There is.

In this embodiment, two holding portions 15 are provided for one protruding portion 121 of the arm portion 12. As can be seen from FIGS. 4 and 6, the hole 14 between the holding portion 15 and the holding portion 15 has a larger opening than the other hole portions 14. As a result, the two binding members 81 can be inserted into the holes 14 having the large openings, and the number of the holes 14 can be suppressed.

Although the above description has focused on one embodiment, the present invention is not limited to the above embodiment and can be in various modes. For example, the binding member may be any as long as it can be passed through the hole to fix the cable. For example, it may be a hook-and-loop fastener or a band called a binding band.
