[Means for Solving the Problems]

In order to achieve the above-mentioned object, the window glass lifting device of the present invention has two guide rails formed by continuously connecting a vertical rod portion facing vertically to both ends of a substantially horizontal rod portion facing the front-rear direction. A pair of cable guide grooves for guiding the cables independently of each other in the longitudinal direction are provided, and front and rear vertical rods of the guide rail are fixed to one ends of the different cables, respectively, and the window glass is provided. And a holder guide groove, which is respectively coupled to the front and rear parts of the front and rear parts, for guiding the pair of front and rear glass holders supporting the window glass so as to be slidable in the vertical direction, and the both cables are synchronized with each other at appropriate positions of the guide rail. Then, driving means for raising and lowering the window glass together with the glass holders is provided by moving the window glass in the opposite direction.

It is preferable that a part of the guide rail is projected upward from the outer panel and the inner panel of the door, and the projecting portion serves as a glass sash (see FIG. 2).

Most of the drive means is preferably arranged outside the ascending / descending path of the window glass when viewed from the side of the door (see FIG. 6).

The guide rail can be upwardly U-shaped (see FIG. 1) or downwardly U-shaped (see FIG. 6).

The method of assembling the window glass lifting device of the present invention to a door of an automobile is as follows. After assembling two cables, a driving means, a glass holder and a window glass to a guide rail, the guide rail is attached to an inner panel of the door. And the outer panel, and then the guide rail is sandwiched between the inner panel and the outer panel so that the outer peripheral edge portions of the inner panel and the outer panel are connected to each other at appropriate positions.

When carrying out this method, if other functional parts in the door are attached to the guide rail before fixing the guide rail to either the inner panel or the outer panel, the work of attaching to those doors will be easy. Becomes
