<p><P>PROBLEM TO BE SOLVED: To provide a guide with a ball that safely and further smoothly leads a cable in and out of a handhole and a trough from a variety of angles with less man-hour, and to provide a guide jig for use in the guide. <P>SOLUTION: In each of the guide jigs, the ball is rotatably housed in each of a large number of vessels continuously connected in one row or in a plurality of rows. The jigs are annularly attached to internal peripheral surfaces of arbitrary places in the longitudinal direction of a corrugate tube. A large number of the guide jigs with the balls rotatably housed in the vessels are annularly attached to the internal peripheral surfaces of the arbitrary places in the longitudinal direction of the corrugate tube. The guide jigs are connected in one row or in the plurality of rows, and rotatably house the balls in the vessels. The vessels are annularly attachable to the arbitrary places in the longitudinal direction of the corrugate tube. <P>COPYRIGHT: (C)2004,JPO</p> |
