  A sealing screen 10 is provided on the vehicle inner side of the door inner panel 3 to cover all or one of the openings 3a, 3b, 3c (in this embodiment, the openings 3a, 3c excluding the opening 3b). The peripheral part of the sealing screen 10 is liquid-tightly attached to the door inner panel 3 using, for example, butyl rubber-based adhesive K or the like, and water that has entered from the entrance / exit of the window glass 5 enters the vehicle interior through the openings 3a and 3c. It is designed to stop intrusion. In addition, since the opening part 3b is covered with the speaker, possibility that water will penetrate | invade through the said opening part 3b is low.

  In this embodiment, when the sealing screen 10 is pasted, an appropriate interval (for example, an interval of about 15 mm) is provided between the general portion of the sealing screen 10 and the door inner panel 3, and the sealing screen 10 is connected to the door inner. The chatter noise and vibration generated by contacting the panel 3 are suppressed.

  As shown in FIG. 1, the sealing screen 10 is provided with a notch (slit) 11 at a portion where there is a low risk of being wet, and the harness 6 described above is taken out from the notch 11 to the inside of the vehicle. Is routed along the sealing screen 10. As shown in FIG. 3, the harness 6 is thickened by assembling a plurality of single harnesses 6 a, and appropriate portions of the harness 6 are fastened to the door inner panel 3 by clips 20.

  As shown in FIG. 3, the clip 20 is provided with a band 21 for binding the harness 6 at one end (inside the vehicle), and a tip collar 22 is formed at the other end (vehicle outside). A collar portion 23 is provided at the base portion of 22. A flange portion 22a that opens and closes with a resilient force is formed in the tip flange portion 22 in a V-shaped cross section.

  Then, when the clip 20 is fixed to the door inner panel 3, the sealing screen 10 is pierced from the vehicle inner side by the front end flange portion 22 and is inserted into a locking hole 3 d formed in the door inner panel 3 in advance. Then, the flange portion 22a that penetrates the locking hole 3d expands on the vehicle outer side, and is locked by being locked to the vehicle outer peripheral edge portion of the locking hole 3d. At this time, the flange 23 is pressed against the inner side of the sealing screen 10 so that the sealing screen 10 at that portion is pressed against the door inner panel 3.

  By the way, regarding the attachment of the harness 6 to the clip 20, after the clip 20 is fixed to the door inner panel 3, the harness 6 may be bound by the band 21, or after the harness 6 is bound by the band 21, The clip 20 may be fixed to the door inner panel 3.

  Here, in this embodiment, as shown in FIG. 3, the thin part 12 is formed in the site | part which penetrates the clip 20 of the sealing screen 10. As shown in FIG.

  Further, the thin portion 12 is provided at least on the bottom wall 13a of the embossed portion 13 in which the sealing screen 10 is recessed (inside the vehicle as viewed from the vehicle inner side) (in other words, the top wall protruding on the vehicle outer side). It has become.

  That is, in the present embodiment, the embossed portion 13 is evacuated with a predetermined shape (circular shape) when molding the sealing screen 10, so that the embossed portion 13 has a predetermined depth D from the general portion of the sealing screen 10 to the outside of the vehicle. It is formed to be recessed. At this time, an annular wall 13b is formed around the embossed portion 13 so as to surround the bottom wall 13a.

  In the present embodiment, when the embossed portion 13 is evacuated, the annular wall 13b is formed so as to be thinner than the general portion of the sealing screen 10 in addition to the bottom wall 13a. In addition, the diameter of the bottom wall 13a of the embossed portion 13 is set to a size that can absorb an attachment error with respect to the locking hole 3d of the door inner panel 3.

  Further, as shown in FIG. 4, a ring-shaped sealing member formed of a flexible cushion material such as sponge is provided on the contact surface 23 a of the flange portion 23 of the clip 20 on the sealing screen 10 along the peripheral edge portion thereof. 24 is attached. When the clip 20 is fastened to the door inner panel 3, the sealing member 24 is pressed against the sealing screen 10 to improve the liquid-tightness, and the thickness of the sealing screen 10 is reduced by reducing the thickness. The flange portion 23 of the clip 20 is in direct contact with the thin portion 12 to prevent the sealing screen 10 from being damaged.

  With the above structure, the vehicle door harness fixing structure according to the present embodiment forms the thin wall portion 12 in the sealing screen 10, and the clip 20 is pierced through the thin wall portion 12 and fixed to the door inner panel 3. I tried to wear it. For this reason, when the clip 20 is fastened to the door inner panel 3, the thin portion 12 can be more easily pierced by the distal end flange portion 22 of the clip 20 with a relatively small pressing force. Therefore, the operation | work which fastens the harness 6 to the door inner panel 3 can be performed more easily and rapidly, the productivity of a vehicle can be improved, and a worker's fatigue degree can be reduced.

  In the present embodiment, the sealing screen 10 is recessed to form the embossed portion 13, and the thin portion 12 is provided on at least the bottom wall 13 a of the embossed portion 13. For this reason, when the clip 20 penetrates the thin-walled portion 12, the region (the bottom wall 13a and the annular wall 13b) that can be deformed by being pulled by the clip 20 in the sealing screen 10 and the amount of deformation thereof are made larger. Can do. Therefore, the tension of the portion of the sealing screen 10 (thin wall portion 12) to be pierced by the clip 20 can be reduced, and the sealing screen 10 (thin wall portion 12) can be prevented from tearing at the portion.

  Further, the amount of displacement (movable amount) of the thin portion 12 is increased by the amount of the annular wall 13b, and the amount of error in the mounting position of the sealing screen 10 with respect to the door inner panel 3 can be increased. . That is, even if the position where the clip 20 penetrates the thin wall portion 12 is slightly shifted from the locking hole 3d of the door inner panel 3, an excessive tension is applied to the general portion of the sealing screen 10. The clip 20 can be locked in the locking hole 3d.

  By the way, when passing the clip 20 through the sealing screen 10, it may be possible to form a through-hole in the sealing screen 10 in advance. In this case, the relative displacement between the door inner panel 3 and the sealing screen 10 is considered. The roses will increase. For this reason, in order to absorb the variation, the opening diameter of the through hole must be increased, and the gap between the through hole and the clip is inevitably increased, resulting in a decrease in waterproofness.

  In this respect, according to the harness fastening structure for a vehicle door according to the present embodiment, since the sealing screen 10 is directly pierced by the clip 20, the size of the opening can be made as small as possible and the deterioration of waterproofness is suppressed. be able to.

  Further, when the sealing screen 10 is molded using a mold, the thickness of the general part of the sealing screen 10 tends to increase. However, the harness fastening structure for a vehicle door according to the present embodiment has a thin-walled part. Since the clip 20 is passed through 12, this is also effective when the thickness of the general part is increased.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the case where the vehicle door harness fastening structure according to the present invention is applied to the front door 1 is illustrated, but the present invention is similarly applied to other vehicle doors such as a rear door and a back door. Of course you can. Moreover, the harness 6 fastened with the clip 20 is not limited to that of the electric regulator, but may be a harness of other electrical components mounted on the door. Furthermore, the number and shape of the openings of the door inner panel 3 covered with the sealing screen 10 are not limited to the above embodiment.
