Claim:
A sub-arm assembly of a window regulator, comprising: a sub-arm pivotally coupled to a main arm of the window regulator in an X-shape, wherein upper ends of the sub-arm and the main arm are configured to support a lower end of glass and a lower end of the sub-arm is configured to be slidable on a base panel; a sliding bar pivotally coupled to the lower end of the sub-arm; and a guide rail integrally formed with the base panel so as to extend from the base panel and having a space to slidably receive the sliding bar; wherein a length of the guide rail in a movement direction of the sliding bar is shorter than a length of the sliding bar in the movement direction of the sliding bar, wherein the guide rail comprises: a first pair of guide portions extending substantially in a vertical direction from the base panel and being in close contact with upper and lower ends of the sliding bar, respectively; bent portions which are bent from distal ends of the guide portions toward the sliding bar to prevent the sliding bar from becoming detached from the guide portions; a second pair of guide portions extending substantially in a vertical direction from the base panel and being in close contact with upper and lower ends of the sliding bar, respectively; and bent portions which are bent from distal ends of the second pair of the guide portions toward the sliding bar to prevent the sliding bar from becoming detached from the second pair of the guide portions, wherein the first pair of the guide portions and the second pair of guide portions are spaced with a predetermined distance therebetween.
