According to the present invention, on the through opening edge portion, the flange portion is formed, and by arranging the outer surface of the axle portion to slide and rotate on the inner face of the flange portion, the first and second equalizer arms are pivotally supported by the lift arm. The circular projected portion formed around the axle portion contacts on the lift arm face to provide the predetermined clearance between the top portion of the flange portion and the lift arm face, and undesirable friction increase or stick slip there between is avoided. The lift arm and the first and second equalizer arms can be made of thinner steel plate material, and weight and cost reduction is obtained. The flange portion and the through opening are formed by burring on the lift arm, and also the axle portion and the circular projected portions are formed by stamping directly on the first equalizer, and also the weight and cost reduction of the window regulator is realized.
