PROBLEM TO BE SOLVED: To improve work efficiency in connection work, etc., of a branch cable to be added, without disassembling the end face member to serve as a cable introduction part, by inserting a branch cable rectilinearly in order of elastic seal material being accommodation space and the hole of a cover, with the guide hole at the base part as a guide, from outside the base part. SOLUTION: A sleeve 1 comprises a base part 2 which has a plurality of guide holes 20, in parallel with each other and accommodation space 21 whose one end leads to the guide holes 20 and whose other end is open and which is positioned on the extension in the axial direction of the guide holes 20, a cover which is plugged in the opening 21a of the accommodation space 21, and elastic seal material 2 which is transformed elastically, being charged in the accommodation space 21 of the base part 2. Any one of those is retained in drip-proof condition by simple operation and besides can be sealed, merely by incorporating and coupling it to the end member arranged in the opening of a connection box, in advance together with a support cable and a main cable, and merely by inserting the branch cable in order of the guide hole 20 of the base part 2, the elastic member within the accommodation space 21, and the hole 30 of the cover 3. |
