<p>PROBLEM TO BE SOLVED: To materialize the bending, sending, and guiding of a cable with a single guide roller, securing a proper redundant length not to give excessive bends to a cable. SOLUTION: When constituting a cable guide apparatus which bends, sends, and guides a cable in the middle of extension, a spiral cable guide steps 4 which guide a cable to be extended while pushing down the shifting cable ca on a roller 1 from the large-diameter periphery 2 to the small-diameter periphery 3 is made at the periphery of the roughly conical roller 1, and also the center of the roller 1 is pivoted by an installation member 7 through a pivotal shaft 5 and a support piece 6 to support this pivotal shaft. Furthermore, a spiral guide steps 4 which guide a cable to be extended while pushing down the shifting cable ca on the roller 1, at least from the large-diameter periphery 2 to the small-diameter periphery 3 at the center, is formed at the periphery of the roller, as a whole, roughly in the shape of a drum, and also the center of the roller 1 may be pivoted by the installation member 7 through the pivotal shaft 5 and the supporting piece 6, to supporting this pivotal shaft.</p> |
