Each height dimension along the axial direction Y of the first annular protrusion 37 and the shaft portion 36 straddling the flange wall 35 is necessarily larger than the height dimension H of the flange wall 35. The total height of both the first annular projection 37 and the shaft portion 36 exceeds twice the height H of the flange wall 35.

  Therefore, when the conventional window regulator device 31 presses the material plate of the first equalizer arm 33 to integrally form the shaft portion 36 and the first annular protrusion 37 which are large in height and approach each other, Due to the large plastic deformation amount that 36 and 37 are combined, defects such as cracks are likely to occur in both 36 and 37 and the periphery thereof, and there is a problem in that fatigue breakage or the like is caused by a large load applied when the window is opened and closed.

  In order to solve the above-described problem, an object of the present invention is to provide a window regulator device that can reduce the burden of plastic deformation when molding a shaft portion and a first annular protrusion on an equalizer arm.

The drive mechanism 19 includes a known motor and a manual handle, and includes a pinion gear 19a that rotates by driving the motor and the manual handle. A sector gear 20 is fixed to the base end of the lift arm 2 so as to rotate integrally. The sector gear 20 meshes with the pinion gear 19a of the drive mechanism 19 at the arc tooth portion 20a.

  In such a configuration, when the drive mechanism 8 is operated, the lift arm 2 is rotated by meshing between the pinion gear 8a of the drive mechanism 19 and the circumferential tooth portion 20a of the sector gear 20. By the rotation of the lift arm 2, the rail 14 is moved up and down with the window glass in the vertical direction of the door to open and close the window portion of the vehicle door. At this time, the shoe 15 slides in the rail 14 and absorbs the difference between the rotation locus of the arm 2 and the elevation locus of the rail 14. The first and second equalizer arms 3 and 4 rotate with respect to the lift arm 2 as the rail 14 moves up and down to maintain the posture of the rail 14. At this time, the shoes 16 and 18 slide in the rails 14 and 17.

  As shown in FIG. 2, a through hole 2 a is formed in the approximate center in the longitudinal direction of the lift arm 2. A bearing flange wall 5a that protrudes toward the one surface 2b of the lift arm 2 is provided on the periphery of the through hole 2a. The through hole 2a and the flange wall 5a are integrally formed by burring.

Is done.

  In the first equalizer arm 3, the sliding contact of the first annular protrusion 7 with the one surface 2 b of the lift arm 2 creates a gap D in the axial direction Y between the front end 5 a of the flange wall 5 and the flange wall 5. A gap in the radial direction is formed between the inner peripheral surface 5b and the tip of the inner peripheral surface 5b. As a result, the hooking of the first and second equalizer arms 3 and 4 with respect to the lift arm 2 is eliminated. The sliding contact between the first and second annular protrusions 7 and 8 and the one surface 2 b and the other surface 2 c of the lift arm 2 forms closed spaces B and C around the shaft portion 6. The closed spaces B and C store grease applied to the outer peripheral surface 6b of the shaft portion 6 and the inner peripheral surface 5a of the flange wall 5, and thereby, the outer peripheral surface 6b and the inner peripheral surface 5a, that is, the sliding contact portion. The grease break is eliminated, and smooth rotation of the first and second equalizer arms 3 and 4 with respect to the lift arm 2 is ensured. Further, the grease stored in the closed spaces B and C also acts on sliding contact between the first and second annular protrusions 7 and 8 and the one surface 2b and the other surface 2c of the lift arm 2.
