In other words, the bead portion 741, the bead portion 742, and the gap (exit) form a predetermined path. This makes it easier for rainwater that has fallen along the one-side circumferential edge 913 and the other-side circumferential edge 914 to flow along a predetermined path, making it difficult for rainwater to splash onto the yoke of the drive motor 56, for example. Specifically, the water flowing down through the gap (exit) is guided to one side in the width direction along the walls provided at 32g and 32e, and a yoke 56 is provided with the guide rail 31 in between. It is discharged on the opposite side.

(Comparative example)
Next, the structure of the carrier plate 320 in a comparative example will be described with reference to FIG. 7. FIG. 7 is a diagram showing a part of the structure of a carrier plate 320 in a comparative example. In the description of the comparative example, configurations that are different from the present embodiment will be mainly explained, and the same configurations will be given the same reference numerals and the description thereof will be omitted.

The carrier plate 32 in this embodiment shown in FIG. 6 has a wall 733. In contrast, the carrier plate 320 in the comparative example does not have the wall 733.

Further, the wall 733 in this embodiment is spaced apart from the guide portion 743 by a predetermined distance to one side in the width direction (+Y direction), and a flow path 744 is formed between the wall 733 and the guide portion 743. There is. In contrast, the carrier plate 320 in the comparative example has the guide portion 743 but does not have the wall 733 and does not have the flow path 744 formed therein.

From the above, in the carrier plate 320 in the comparative example, as shown in FIG. It will fall to the other side (-Y direction).

On the other hand, since the carrier plate 32 in this embodiment has the flow path 744 formed therein, rainwater that has fallen along the other side peripheral edge 914 can flow into the flow path 744. Conventionally, when the mounting position of the holder 91 is closer to the other side in the width direction, the flow path becomes narrower and rainwater overflows from the flow path, but in this embodiment, by positioning the holder 91, the flow path can be reliably closed. This makes it possible to prevent rainwater from overflowing.

Further, the carrier plate 32 in this embodiment has a bead portion 741 and a bead portion 742. In contrast, the carrier plate 320 in the comparative example does not have the bead portion 741 and the bead portion 742.

From the above, the carrier plate 320 in the comparative example cannot allow rainwater that has fallen along the one side peripheral edge 913 of the holder 91 to flow in a predetermined path. On the other hand, since the carrier plate 32 in this embodiment has the bead portion 741 and the bead portion 742, the rainwater that has fallen along the one side peripheral edge 913 can flow in a predetermined path.

Note that, as shown in FIG. 3, the upper edge 32d of the carrier plate 32 in the above embodiment is a substantially horizontal surface, but the upper edge 32d is inclined toward the side where the guide portion 743 is provided. It is also possible to provide an inclined portion to

Hereinafter, this inclined portion will be explained in detail using FIGS. 8 to 10. FIG. 8 is a perspective view of the carrier plate 32 having a sloped portion 800. FIG. 9 is a side view of the upper edge 32d on which the inclined portion 800 is formed. FIG. 9 is a view of the upper edge 32d viewed from the other side in the width direction (-Y direction) of the carrier plate 32.

As shown in FIGS. 8 and 9, the upper edge 32d of the carrier plate 32 is formed with an inclined portion 800 and a surface 801 provided between the inclined portion 800 and the flat surface of the upper edge 32d. There is.

The upper edge 32d is the end on the side where the window glass is placed in the attachment part 73 to which the holder 91 shown in FIG. 6 is attached. Further, the surface 801 is a surface that substantially perpendicularly intersects with the flat surface of the upper edge portion 32d on one side and intersects with the inclined surface 800 on the other side.

Furthermore, the flat surface of the upper edge 32d is a surface on which a part of the holder 91 is placed. In FIG. 9, a holder 91 placed on the flat surface of the upper edge 32d is shown in dotted lines.

By providing an inclined portion 800 that slopes toward the side where the guide portion 743 is provided on the upper edge portion 32d, water that has fallen along the surface of the holder 91 is directed to the bead portions 741, 742 and the guide portion 743. It can flow along a predetermined path formed by

Further, by providing a flat surface on which a part of the holder 91 is placed on the upper edge 32d, the holder 91 can be stably supported by the carrier plate 32.

Note that when attaching the holder 91 holding the window glass to the carrier plate 32 from above (+Z direction), the carrier plate 32 is located in the middle part of the guide rail 31.

In this case, the ascending cable 33 pulls the portion of the carrier plate 32 shown in FIG. It rotates counterclockwise when viewed from below (-Z direction) about the part that fits into the guide groove 75 (see FIG. 5) of No. 31 as an axis.

Therefore, the attachment part 71 on the left side (+Y direction) of the carrier plate 32 moves to the back side (-X direction) of the paper, and the attachment part 73 on the right side (-Y direction) moves to the front side (+X direction) of the paper plane. direction).

In such a situation, if you try to attach the holder 91 to the attachment part 73 of the carrier plate 32 from above (+Z direction), the bottom of the holder 91 will come into contact with the upper edge 32d of the carrier plate 32, and the attachment of the holder 91 will become impossible. It becomes difficult to do.

On the other hand, if the sloped part 800 is provided on the upper edge 32d, the bottom of the holder 91 is smoothly guided by the sloped part 800 to the predetermined position of the mounting part 73 of the carrier plate 32, so that the carrier plate 32 is Even if it rotates, the holder 91 can be easily attached.

Further, as shown in FIG. 9, by forming a surface 801 that intersects substantially perpendicularly with the flat surface of the upper edge 32d, the area of the flat surface of the upper edge 32d and the area of the inclined portion 800 are reduced. While preventing this, the bottom of the holder 91 can be more smoothly guided to a predetermined position of the attachment part 73 of the carrier plate 32 via the inclined part 800.

Furthermore, in FIGS. 8 and 9, the case where the surface 801 is formed on the upper edge 32d of the carrier plate 32 has been described, but the surface 801 is not necessarily necessary. FIG. 10 is a side view of the upper edge 32d without a surface 801 that intersects substantially perpendicularly with the flat surface of the upper edge 32d. FIG. 10 is a view of the upper edge 32d viewed from the other side in the width direction of the carrier plate 32.

The inclined portion 800 shown in FIG. 10 intersects with the flat surface of the upper edge 32d on one side, and intersects with the wall 731 of the mounting portion 73 on the other side.

Even with such a configuration, water that has fallen along the surface of the holder 91 can flow along a predetermined path formed by the bead portions 741, 742 and the guide portion 743. Further, even if the carrier plate 32 rotates around the guide rail 31, the holder 91 can be easily attached.

Furthermore, in FIGS. 8 to 10, a case has been described in which the sloped part 800 is provided on the upper edge 32d of the mounting part 71 and the mounting part 73 on the side of the mounting part 73. A similar sloped portion may be provided on the upper edge 32d. Further, similar sloped portions may be provided on both the upper edge 32d on the side of the attachment portion 71 and the upper edge 32d on the side of the attachment portion 73.

However, as described above, since the carrier plate 32 rotates counterclockwise around the guide rail 31 when viewed from below (-Z direction), the carrier plate 32 is inclined at least toward the upper edge 32d on the side of the mounting portion 73. It is desirable to provide a section 800.

Further, in FIGS. 8 to 10, the case where the sloped portion 800 is a flat surface has been described, but the sloped portion 800 may be a convex surface or a concave surface. However, it is more preferable to make the inclined portion 800 a flat or concave surface because this allows the bottom of the holder 91 to be stably guided to a predetermined position of the attachment portion 73 of the carrier plate 32.

The carrier plate 32 in this embodiment described above is a carrier plate to which a window glass is attached via the holder 91 and slides on the guide rail 31, and includes a mounting portion 73 to which the holder 91 is attached, and a portion of the mounting portion 73. A guide part 743 is provided on the other side and guides water falling along the other side periphery 914 of the holder 91 downward; and a wall 733 that regulates the mounting position of the holder 91, and is configured such that water that has fallen along the other side periphery 914 flows through a flow path 744 provided between the guide portion 743 and the wall 733. be done.

With the above configuration, a flow path 744 is formed between the guide part 743 and the wall 733 that is a predetermined distance away from the guide part 743 on one side in the width direction, so that the flow path 744 is formed between the guide part 743 and the wall 733 that is a predetermined distance away from the guide part 743 on one side in the width direction. Water can flow through channel 744.

Furthermore, in the carrier plate 32 in the above embodiment, the wall 733 has an inclined surface 734 that is inclined toward the guide portion 743 side. As a result, when the water that has been transmitted to the other side peripheral edge 914 of the holder 91 reaches the wall 733, the inclined surface 734 guides the water toward the guide part 743, so that the water that has been transmitted to the other side peripheral edge 914 and falls down reaches the wall 733. This allows water to flow into the guide portion 743.

Further, the carrier plate 32 in the above embodiment falls along the one side periphery 913 on the opposite side to the other side periphery 914 of the holder 91 on the side opposite to the side where the wall 733 of the mounting portion 73 is provided. It further includes bead portions 741 and 742 that guide the water downward. This allows the water that has traveled to the one side peripheral edge 913 to flow down along a predetermined path.

Further, in the carrier plate 32 in the above embodiment, one end of the bead portion 742 extends toward the guide portion 743, and the outlet of the flow path 744 formed between the wall 733 and the guide portion 743 is Partially surrounded by the tip of the bead portion 742, the wall 733, and the guide portion 743, water flowing out from the flow path 744 and water guided by the bead portion 742 merge, and the combined water is transferred to the bead portion. A merging region 731c is formed between the tip of the guide portion 742 and the guide portion 743 and flows downward along the guide portion 743. This allows the water flowing along the bead portion 742 and the water flowing through the guide portion 743 to merge in the merging region 731c. Further, while maintaining the momentum of the water flowing through the flow path 744, the water flowing along the bead portion 742 from one side in the width direction can also be drained in a common manner, making it possible to drain water easily and effectively. Further, since the merging region 731c is provided below the wall 733 and closer to the other side in the width direction, there is no need to change the arrangement of the descending end holder 81, etc., and the descending end holder 81, etc. Layout etc. become easier.

Further, in the carrier plate 32 in the above embodiment, a notch 745 is formed by cutting out a part of the flow path on the upstream side of the flow path 744 formed between the wall 733 and the guide portion 743. There is. As a result, the water that has been transmitted to the other side peripheral edge 914 of the holder 91 moves to the upstream side of the flow path 744 along the notch 745 and passes through the flow path 744, so that it is transmitted to the other side peripheral edge 914. It becomes possible to cause the water that has fallen to flow into the channel 744.

In addition, in the carrier plate 32 in the above embodiment, the upper edge 32d of the attachment portion 73 on the side where the window glass is attached has an inclined surface 800 that is inclined toward the side where the guide portion 743 is provided. Thereby, water that has fallen along the surface of the holder 91 can flow along a predetermined path formed by the bead portions 741, 742 and the guide portion 743. Further, even if the carrier plate 32 rotates around the guide rail 31, the holder 91 can be easily attached.

Furthermore, in the carrier plate 32 in the above embodiment, the upper edge 32d has a flat surface on which a part of the holder 91 is placed. Thereby, the carrier plate 32 can stably support the holder 91.

Furthermore, in the carrier plate 32 in the above embodiment, the upper edge 32d has a surface 801 that intersects with the flat surface substantially perpendicularly on one side and intersects with the inclined surface 800 on the other side. This prevents the area of the flat surface of the upper edge 32d and the area of the sloped part 800 from becoming small, and allows the bottom of the holder 91 to be attached to a predetermined position of the mounting part 73 of the carrier plate 32 via the sloped part 800. It can be guided to the desired position more smoothly.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the invention. In particular, the multiple embodiments and modifications described in this specification can be arbitrarily combined as necessary.

The present invention can be applied to a window regulator for driving the window glass of an automobile up and down.
