(57) [Problem] To provide a sliding cable duct in which a cable duct can be installed simply by pulling out one end of the duct without requiring duct connection. The sliding cable duct has a plurality of ducts having similar cross-sectional shapes and other ducts than the duct having the maximum cross-sectional shape can be accommodated by sliding in the duct having the maximum cross-sectional shape. Since the cable duct is constructed by pulling out the cable, it can be transported by the length of one duct, and since it is not necessary to connect the duct, it can be inserted and installed even in a place where there is a restriction of an inspection port behind the ceiling.
