<p>PURPOSE: To facilitate the centering by fixing a pair of hourglass type guide rollers to supporting bases provided such that they can slide independently through linear guides mounted on a supporting plate and then sliding the guide rollers on a linear guide by turning a threaded rod thereby gripping a cable while retaining the central axis. CONSTITUTION: A guide roller supporting plate 2 is provided with two parallel linear guides 4 for permitting independent sliding of supporting bases 3A, 3B. The supporting bases 3A, 3B are fixed with a pair of hourglass type guide rollers 1A, 1B. A threaded rod 5 comprises a first half part threaded forward 5A and a second half part threaded reversely 5B being screwed into screw holes. When the threaded rod 5 is turned, the supporting bases 3A, 3B advance simultaneously toward a cable C and grip the cable C while retaining the central axis. With such structure, the centering is facilitated and the tapered part or the level difference part, as well as the linear part, of a cable can be guided while retaining the central axis.</p> |
