<p>PROBLEM TO BE SOLVED: To provide an apparatus which facilitates laying an additional cable to a cable trough 2, in which cables 51a to 51e have already been laid. SOLUTION: A cable laying apparatus 1 has a pair of first rolling rings 11, which are placed at both ends of the lengthwise axis of a rod 3, and a second rolling ring 12, which is placed at a lower position than the lengthwise axis of the rod 3 and in a direction almost perpendicular to the lengthwise axis of the rod 3. When the rod 3, which is installed with the cable laying apparatus 1, is inserted into the cable trough 2 attached with a cap 22, each of the first rolling rings 11 rolls on a side 21a of a trough body 21 and the second rolling ring 12 rolls on surfaces of the existing cables 51a to 51e.</p> |
