The wire 6 is wound around the pulley 9 so as to be routed between the electric motor M and the pulley 9 so as to have a pair of front and rear movement paths along the vertical direction. The carrier plate 5 is connected to the wire 6 in one movement path. With the above configuration, the electric motor M rotates in the forward and reverse directions, and the wire 6 rotates in the forward and reverse directions, whereby the carrier plate 5 moves in the vertical direction, and the window glass G moves up and down.

At least a part of the pair of vertical sash portions 3A on the downward extension line in the state where the window glass G is located at the lowermost position, at least the window glass G.
Glass side supporting means 11 for holding a part of both sides of the glass is provided. In the form shown in FIGS. 1 and 2, the glass side part supporting means 11 is composed of a sash extension part 3D obtained by extending a pair of vertical sash parts 3A downward. Similar to the case of the vertical sash portion 3A, the sash extension portion 3D is formed to have a groove into which the side edge portion of the window glass G can be inserted, for example.

As can be seen from FIG. 2, the pair of sash extension portions 3D are extended downward so that both side portions of the window glass G are held (guided) when the window glass G is located at the lowest position. It is provided. A mode in which the rotation of the window glass G can be prevented, and when a predetermined holding performance of the window glass G is obtained, the window glass G is extended downward to at least a part (upper side) of both side portions of the window glass.

As an example of the shape of the guide roller 12, a concave portion into which the side portion of the window glass G is fitted is provided in the center of the peripheral surface thereof. If the rotation of the window glass G can be prevented and a predetermined holding performance of the window glass G is obtained,
The number of the guide rollers 12 and the vertical mounting interval and the like are not particularly limited.

As the glass side supporting means 11,
For example, instead of the guide roller 12, a guide pin or a guide bracket (both not shown) may be locally arranged on the downward extension line of the vertical sash portion 3A.

As described above, at least a part of the extension line of the vertical sash portion 3A holds at least a part of both sides of the window glass G in a state where the window glass G is located at the lowermost position. If the means 11 is provided, the carrier member (carrier plate 5)
It is possible to realize a structure that does not require a mechanism (such as a guide rail that supports the carrier member) for holding the ascending / descending locus. That is, since the vertical dimension (height dimension) of the window glass G is large, for example, the window roller G and the guide pins are only locally arranged, and thus the window glass G is provided.
It is possible to guide (rotation prevention) when moving up and down, and it is possible to prevent rotation of the window glass G when moving up and down with a simpler structure than the conventional structure in which a guide rail for supporting the carrier member is provided. Further, the vehicle door can be reduced in weight.

Then, for example, the window glass G is supported by the carrier plate 5, and then the carrier plate 5 is simply moved up and down to arrange the wire 6 only between the drive means 7 and one support means 8. With the configuration,
The carrier plate 5 can be moved up and down with a simple structure. That is, the wires 6 can be arranged in a simple track shape so as to have a pair of movement paths along the vertical direction between the driving means 7 and the supporting means 8 without intersecting the wires as in the conventional case. Therefore, the number of supporting means 8 such as the pulley 9 for arranging the wires 6 can be minimized, the weight of the entire door can be reduced, and the cost of parts can be reduced.

With this configuration, it is possible to prevent rotation of the window glass G inside the door panel portion 2 with a simple structure, and to smoothly move up and down. That is, as a member that holds (guides) the window glass G in the door panel portion 2, it is not attached as a separate member from the sash portion 3 but is integrally attached as an extension portion of the vertical sash portion 3A. Thus, the assembling work can be simplified and the number of parts can be reduced. Of course, it is not necessary to separately provide a mechanism for holding the ascending / descending trajectory of the carrier plate 5 (such as a guide rail for supporting the carrier member), so that the window regulator has a small number of parts and is easy to assemble. In addition, in the present embodiment, the extension portion integrated with the vertical sash portion 3A is the glass side portion supporting means 11, but as another embodiment,
An extension portion formed separately from the vertical sash portion 3A may be used as the glass side portion supporting means 11.

Further, if a tubular wire cover 13 is provided so as to cover the wire 6, the driving means 7 and the supporting means 8 are provided.
It is possible to regulate the deformation and twist of the wire 6 routed between the wire and the wire. Therefore, the window regulator 4 including the carrier plate 5, the wires 6, the driving means 7, the supporting means 8 and the like.
It is possible to maintain the arrangement shape as a single body in the arrangement shape in the state of being attached to the door panel portion 2, and thus the workability when assembling the window regulator 4 to the door panel portion 2 can be improved.

Therefore, the wire cover 13 is preferably made of a material having low flexibility, and in this embodiment, it is made of a hard polypropylene pipe material. Also,
If the wire cover 13 is provided only on the movement path side of the wire 6 to which the carrier plate 5 is not connected, that is, only on one movement path of the wire 6, the vehicle doors are provided as a pair of left and right, This makes it easy to distinguish the pair of window regulators 4 that are formed symmetrically when assembling them into the door panel portions 2, and improves the assembly workability.

Further, the carrier plate 5 and the driving means 7
By providing an elastic material at the side where the window glass G or the supporting means 8 side comes into contact, the impact caused by the contact between the carrier plate 5 and the driving means 7 or the supporting means 8 at the most lowered position or the most raised position of the window glass G is provided. It can be absorbed and the generation of unpleasant collision noise can be prevented. In this embodiment, the carrier plate 5
In the above, the elastic member 14 is provided on the side contacting the driving means 7 side,
The elastic member 15 is provided on the side in contact with the supporting means 8 side.

As a result, when the window glass G reaches the lowest position, the elastic member 14 contacts the housing 16 attached to the electric motor M, and when it reaches the highest position, the elastic member 15 is attached to the bracket 10. By making contact, the impact at the time of contact is absorbed. Elastic material 14, 1
5 is made of, for example, a synthetic rubber material. The elastic material 1
4, 15 may be attached to the driving means 7 side and the supporting means 8 side.

Although the preferred embodiment of the present invention has been described above, the layout, shape, etc. of each constituent element are not limited to those shown in the drawings, and the present invention can be appropriately modified in design without departing from the spirit thereof. Is possible.
