Wire-driving device for window regulator

摘要

A compact and thin wire-driving device for a window regulator which absorbs elongation of wire automatically, wherein both ends of a driving wire are wound round two pulleys arranged parallel, i.e. a first pulley and a second pulley, in the same direction; a first gear is secured coaxially to the first pulley; a second gear is adjacent coaxially to the second pulley through ratchet teeth; the first gear and second gear are meshed to each other; and, when the wire is wound up round the first pulley, a slack of the wire is wound up round the first pulley and the second pulley remains stopped.
