<p>PURPOSE:To prevent a cable from causing an inflection point and to improve the endurability of the cable by providing a roller to a bend section in a U-shaped movement cable and by stretching it to one direction in applying tension to the roller shaft to regulate the variation of length of the U-shaped movement. CONSTITUTION:A roller 5 with a radius to meet the flexure radius is provided to a cable 1 having a bend section 4 for reciprocating movement. A spring 7, a stretching means, is hangingly attached to a shaft 6 of the roller 5, with which the reciprocating movement of the roller 5 is absorbed to adjust the tension of the cable 1. The roller 5 is supported to a bearing 9 and no gravity of the roller 5 is applied to the cable 1.</p> |
