ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a window regulator for a vehicle, and more particularly to a window regulator having light weight.
BACKGROUND OF THE INVENTION
Unexamined Published Japanese Utility Model Application (Kokai) No.62(1987)-144380 discloses a window regulator device which includes a lift arm being pivotally connected with a door panel at its one end and engages with a drive mechanism at its another end, a first and second equalizer arms pivotally arranged on the lift arm. The lift arm has a through opening, and the first and second equalizer arms have axle portions respectively. The first equalizer arm is located on the one side of the life arm and its axle portion is inserted to the lift arm's through opening. The second arm is located on the other side of the lift arm and also its axle portion is inserted to the lift arm's through opening. The two axle portion of the both equalizer arms are welded in the lift arm's through opening. The lift arm's through opening pivotally supports the welded axle portion.
However, the window regulator device having foregoing configuration, especially in a case the lift arm's plate thickness is thin, and enough bearing support area for the axle portion is not obtained, tends to increase its operation friction force and suffer luck of durability.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a window regulator for a vehicle which overcomes the foregoing drawbacks.
In order to achieve the object, there is provided window regulator for a vehicle, including: a lift arm pivotally supported on a door panel and connected with window glass at its one end, and engaging with a drive mechanism at its other end, a first and second equalizer arms pivotally supported on the lift arm; wherein a through opening is formed on said arm. A flange is formed on the trough opening edge of the lift arm. An axle portion is formed on the first equalizer arm to penetrate the trough opening, to be connected with the second equalizer arm and to slide on the inside face of the trough opening.
According to another aspect of the invention, the first circular projected portion contacts on the lift arm face to provide a predetermined clearance between the top portion of the flange arm formed to surround the axle portion and the first equalizer arm.
According to another aspect of the invention, the window regulator for a vehicle includes the window regulator for a vehicle wherein the second equalizer has a second circular projected portion around said axle portion to slide on the lift arm face.
According to another aspect of the invention the window regulator for a vehicle includes the through opening and the flange portion are formed by burring process.
