<p>PROBLEM TO BE SOLVED: To enhance the air tightness of an apparatus, by sealing between a columnar body and each cable with a sleeve, on the occasion of inserting the cable into the sleeve having elastically and weather resistance provided hermetically to a hole of the columnar body having a protrusion and holes. SOLUTION: A cable leading-in opening 25 is an opening for taking-in a thick cable from outside into the box 20 of a communication apparatus for outdoor installation, and it is also possible to put a cable in the opening, even if thin cables led into cable leading-in openings 21, 22, 23, 24 are gathered and make a thick cable led into the cable leading-in opening 25. A bush 26 of a columnar body has a protrusion on one side, and has a plurality of through holes penetrating from one end to the other. Rubber sleeves 27, 28, 29, 30, 31 which absorb the size variations of buried plugs or cables, prevent water and dirt from entering from outside, and are weather resistant, are provided hermetically to the insides of the holes penetrating from one end to the other end of the bush 26, and enhance the air tightness between each cable and the bush 26, when cables are inserted into cable leading-in openings.</p> |
