PROBLEM TO BE SOLVED: To eliminate the inconvenience of a prior art such that a cable-wiring device has not been available for use in wiring for an embedding piping work at a high ceiling slab without the use of equipment such as a scaffolding, an elevator car and the like by reason of an expense or the surface irregularities of a floor, due to the existence of an area having a high floor height between a floor and a ceiling under the ground and the like, in an electric work that belongs to a construction work for a building and the like. SOLUTION: A wiring-tool fitting section 14, wherein a plurality of tube- connecting cylinders 13 is mounted at the external peripheral area of a fixing plate 10, and wherein a hook receiver 12 of which the edge is rotatively fitted to the center of the plate by a pin 21 is housed in a hook-receiving notch 11, is formed at a cover 2 for covering a margin to coat up. And, a hollowed guide pipe 37 fitted to the fitting section so as to be capable of rotating around a hook 28 is fitted to a hook-fitting metal 29 so as to surround the side of the metal, and beams capable of contractively housing are connected below the metal. |
