05 is the driven side that is fed out.

As a result, the carrier plate 103 supporting the window panel 111 is configured to be fully closed at the highest position and fully open at the lowest position.

[Problems to be solved by the invention] As described above, the fully open state is obtained at the lowest position of the carrier plate, but the position of the carrier plate 103 at the lowest position is determined by the lowering stop structure. ing.

For example, the lowering stop structure for positioning the carrier plate 103 is shown in FIGS. 13 and 14.
As shown in the figure, a rubber buffer member 117 is fitted into the bent tongue piece 115 provided at the lower edge of the carrier plate 103, and this buffer member 117 is brought into contact with the upper edge 121 of the lower wire guide member 119. It's becoming like that.

Alternatively, the mounting tongue piece 12 provided on the guide rail 101 side as shown in FIGS. 15 and 17
A rubber buffer member 117 is fitted to the carrier plate 103, and an abutting member 125 is provided at the lower end of the carrier plate 103 so that the abutting member 125 touches the buffer member 1 when the carrier plate 103 is lowered.

However, in the former case, the buffer member 11
7 between the rail parts 127 of the guide rail 101.
The rail width L of 01 becomes larger, and the guide rail 1
In addition to this, the carrier plate 103 becomes longer due to the downward protrusion of the buffer member 117, which reduces the downward stroke of the plate 103, which affects the visibility of the occupant. affect In addition, cracks P may form in the corner portions of the through holes of the buffer member 117 due to repeated impacts and stop loads, and in some cases, the cracks may become large and may fall off.

In the latter case, as in the former case, the buffer member 11
There is a risk that a crack P may form in the through hole 7 and the vehicle may fall off, and that the stroke D during descent becomes small, causing problems that affect the visibility of the occupant.

Therefore, this idea does not affect the stroke during descent or the rail width of the guide rail.
Moreover, it is an object of the present invention to provide a carrier plate lowering stop structure for an automobile window regulator that can be installed without falling off and is also preferable in terms of ease of assembly.

[Means for Solving the Problems] In order to achieve the above object, this invention includes a wire whose traction is controlled by the power of a drive unit, and a wire that is connected to the wire and runs up and down along the guide rail. In a window regulator equipped with a slidable carrier plate, an abutment member is provided on the carrier plate side, and a contact member is provided on the guide rail side that engages with the engagement hole of the rail and the wire is wound around the guide rail side. A wire guide member is provided, the wire guide member is provided with a buffer member that abuts the abutment member at the lowest position of the carrier plate, and the buffer member is fitted into the hole of the wire guide member. It consists of a buffer body that fits together, and a mounting leg that extends from the buffer body and engages with the engagement hole of the guide rail to restrain movement in the detachment direction.

[Function] According to this carrier plate lowering stop structure of an automobile window regulator, the buffer body of the buffer member is fitted in advance into the hole of the wire guide member, and the wire guide member is inserted into the guide rail. It can be attached by engaging with the engagement hole. In this case, since it becomes possible to simultaneously engage the mounting legs of the buffer member with the engagement holes, ease of assembly is not impaired. Furthermore, since the buffer body of the buffer member is fitted into the hole of the wire guide member, it will not fall off due to cracks even if it is subjected to repeated impacts or stop loads from the contact member. Further, since movement in the detachment direction is restrained by the mounting legs, the buffer member will not fall off and will not affect the rail width and the downward stroke.
