There is one disclosed in Japanese Utility Model Application Publication No. 58-161079.

That is, this publication discloses a technique in which a stabilizer is attached to a door outer panel and the stabilizer can be adjusted from outside the door outer panel.

``Problem that the invention aims to solve'' However, since the conventional window glass opening/closing device has a stabilizer separate from the opening/closing device, the positional relationship may vary depending on the dimensional accuracy around the door at the time of installation. Therefore, adjustments are required, and as long as such a structure is used, complicated adjustments are forced and become an impediment to streamlining the manufacturing process.Furthermore, since they are separate parts, they must be installed separately. There was a problem in that manufacturing management costs increased because of the need to do so.

The present invention was developed by focusing on these conventional problems, and provides a window glass that solves the above problems by being provided integrally with the lifting device so that the installation position can be determined integrally with the lifting device. The purpose is to provide a lifting device for

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is to provide a windowpane lifting device that is slidably supported on a mounting part, and to follow the up and down locus of the windowpane. A pair of integrally connected guide rails are arranged in parallel, and a carrier plate to which the lower part of the window glass is fixed is fitted into each of the guide rails so as to be able to rise and fall, and an engaging member is attached to the carrier plate. , wherein each of the guide rails is provided with a stopper, and a fitting recess is formed in the other of the engagement members or the stopper to engage with a part of either the engagement member or the stopper at the end of the lifting stroke of the window glass. It consists in a device for lifting and lowering window glass.

``Function'' When the elevating device is assembled, the position of the stopper is automatically fixed, and when the window glass is raised or lowered, at the end of its stroke, the engaging member provided on the carrier plate to which the window glass is solidified engages the stopper. When the two are engaged with each other, the window glass is stopped and the window glass is prevented from swinging.

The biasing force of the spring 58 is increased by the lever action caused by the deviation between the flat roller 53 and the side wall 33, so that even if there is an error in the direction in which the groove 32 separates from the side wall 33, , the roller unit 50 moves through the roller 51 and the flat roller 53 to the guide rail 3 without wobbling due to the urging force of the spring 58.
0 is fitted.

The groove 32 is provided on one side wall 31, and the other side wall 33 has no groove and is flat, so even if the groove 32 is parallel to the side wall 33 and has an error, the flat roller 53 will not move the side wall 33. There is no problem as long as the guide rail 30 moves on the surface of the guide rail 30 itself.

When the window glass A1 is fully closed, the rollers 51 of the roller units 50 of the carrier plates 60, 60a
The tip of the roller 51 is fitted into the fitting recess 37a of the stopper main body 37 of the stopper 35, and the roller 51 is stopped by being regulated by the fitting recess 37a front and rear and left and right. Therefore, the lower end of the window glass A1 is held without wobbling and is stopped reliably.
