CABLE JOINT STORING BOX

PROBLEM TO BE SOLVED: To improve the moisture-proofness of the cable drawing-in part of a cable joint storing box and facilitate drawing-in and drawing-out of a cable. SOLUTION: An approximately U-shaped cut-out 70 is formed in the edge of a storing box body 10 and a rubber component 72 is detachably attached to the cut-out 70. The rubber component 72 is folded at the middle in its longitudinal direction so as to retain a cable 48 in the folded part. The inside of the rubber component 72 which retains the cable 48 is made of soft rubber 78 which is easily deformed when it is pressed against the cable 48. The outside of the rubber component 72 is made of hard rubber 80 which is more difficult to be deformed than the soft rubber 78. Outer fillets 84A and 84B which cover both the side edges of the cut-out 70 are formed on both the ends of the rubber component 72. The inner fillet 86 which covers the other end of the rubber component 72 is formed on the one end of the rubber component 72.
