A device for opening and closing a window portion of a slide door includes a window regulator mechanism having a lift arm whose opposite end portions are connected to a pane and a driving mechanism respectively for moving the pane in the upward and downward directions when the driving mechanism rotates the lift lever in opposite directions. An opening condition detection mechanism has a movable member associated with the lift arm so as to be movable together with the lift lever and a detection member linked to the movable member for indicating whether or not the window portion is closed by the pane.

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.
