PROBLEM TO BE SOLVED: To make it possible to install cables compactly and to sufficiently secure easiness of cable wiring work by wiring in a state where the cables are lined up on an outer wall surface of a building, concerning a duct for cable wiring which is used when cables embedded underground for power, communication, or the like are pulled in along an outer wall surface of a building through a lead-in window provided on an erected outer wall surface into the inside of the building.SOLUTION: The duct for cable wiring comprises: a thin box-shaped body part 1 for wiring cables in an arranged state on an outer wall surface of a building B; and corner parts 2 and 3 for housing a cable bend in an erecting portion from underground where the wiring direction of a cable is veered and a lead-in portion into inside of the building B. The corner parts 2 and 3 have a shape having tapers 21a, 31a, and 31b for reducing the volume of a protrusion from the body part 1, and are fixed to the body part 1 in an add-on fashion after the cable wiring. |
