PURPOSE: A balance arm of a door window regulator for a vehicle is provided to improve work efficiency and to cut down on expenses by forming a balance arm into a solid type having a slide hole in the middle to the exclusion of the arm coupled by welding. CONSTITUTION: A balance arm(10a) is formed into a solid type having a slide hole(14) in the middle and coupled at the rotational central point of a lift arm(12) with riveting to be able to be rotated. The balance arm is formed by an upper arm(18), a central body unit, and a lower arm(24), in one body. The upper end of the upper arm is fixed to a guide rail(30) to be able to be slid. The central body unit is coupled to the lift arm and the central body unit includes the slide hole. The lower end of the lower arm is fixed to a balance arm rail(32) to be able to be slid. The middle part of the lift arm is inserted into the slide hole. The balance arm of a solid type doesn't require coupling with welding and the parts are reduced, and the costs are cut down.
