<p>PROBLEM TO BE SOLVED: To provide a cable tensioning roller device for extending a capable more efficiently. SOLUTION: Rollers 36a-36f are provided at each side position of a hexagonal diameter inside a frame 12 in hollow column shape with a cable rolling in/ feeding out hole 16 so that a cable L can be surrounded, thus constituting a cable tensioning device 10. The rollers 36a-36f are arranged so that its guide surface 38 slightly projects toward the inside of the cable rolling in/feeding out hole 16. Also, the guide surface 38 of the rollers 36a-36f is in curved shape where a center part is recessed so that a circular cable guide hole 17 is formed as a whole.</p> |
