TENSION ADJUSTING MECHANISM FOR CORD OR THE LIKE

摘要

A tension adjusting mechanism for cord or the like can adjust tension more appropriately than conventional ones. The tension adjusting mechanism comprises a wrapping roller (2), for the cord or the like, which is formed such that it can be rotatingly driven by a drive means, detects tension on the cord or the like (C) after leaving the wrapping roller (2), and controls the drive means so as to make the detected tension approach a proper value suitable for the cord or the like (C).
