PURPOSE: A cable conduction support fitting is provided to prevent damages to the outer layer of a newly installed cable by significantly reducing fatigue delivered to the cable. CONSTITUTION: A first, second, and third vertical parts(22,23,24) are vertically extended from a base part(21). The height of the first vertical part which is on the side with a manhole is lower than the heights of the second and third vertical parts which are on the side with a cable drum. Rollers(22a,22b,23a,23b,24a,24b) are installed in each vertical part along the longitudinal direction of the vertical parts and in a traverse direction that is perpendicular to the longitudinal direction. The rollers formed in the second vertical part are formed at a higher location than the rollers formed on the first vertical part. The rollers formed in the third vertical part are formed at a higher location than the rollers formed in the second vertical part. A master mold(27) is formed at the end of the manhole of the base part. The master mold has a diameter which is almost equal to that of the manhole. A circular cable pathway body(52) and a support stand(29) supported by a support stand(28) are formed on the upper part of the master mold. |
