Abstract
A wire-driving device for a window regulator comprising a first pulley secured to a shaft supported rotatably to a casing, a second pulley secured to the shaft so as to be rotatable and axially movable along the shaft, and a wire of which both end portions are wound round said first pulley and second pulley respectively in the opposite direction to each other, the wire being capable to transmit power when the shaft is rotated, and ratchet teeth being provided on each of facing side surfaces of the pulleys, whereby elongation of the wire is automatically absorbed when the shaft is rotated to wind and unwind the wire round the pulleys.
