By fitting, the vertically extending portion 8 is fixed to the door inner panel 3b. At this time, the through hole 8g is closed from the hollow portion 8e side by the head portion 13a of the clip 13.

  An inlet 14 for introducing water into the hollow portion 8e from the gap 9U between the vertically extending portion 8 and the door inner panel 3b is formed above the attachment portion E, while below the attachment portion E. A discharge port 15 for discharging water from the hollow portion 8e toward the gap 9 between the vertically extending portion 8 and the door inner panel 3b is formed.

  The introduction port 14 is elongated in the form of a slit on the opposite surface 8a of the vertically extending portion 8 across both ends in the width direction. And the impermeable wall 16 which suppresses that a water approachs into the clearance gap 9M between the wall 8f by the side of the door inner panel 3b of the hollow part 8e and the said door inner panel 3b along the lower edge of the inlet 14 is provided. It is provided. In the present embodiment, the water-impervious wall 16 is formed as a rib having a projecting face 8a. This impermeable wall 16 corresponds to the second impermeable wall of the present invention.

  That is, in this embodiment, as shown in FIG. 5, by forming a water path (broken arrow) from the inlet 14 to the outlet 15 via the hollow portion 8e, water is supplied to the door inner of the hollow portion 8e. A wall 9f between the panel 3b side and the door inner panel 3b is detoured to flow down to prevent water from entering the upper door 3 through the fitting hole 3c.

  Moreover, in this embodiment, the recessed parts 17A-17D which formed the opposing surface 8a in the side spaced apart from the door inner panel 3b adjacent to the downward direction of the attachment part E are formed. These recesses 17A to 17D are all in the shape of a bottomed rectangular tube and are arranged in a matrix of 2 rows and 2 columns. And the discharge port 15 is opening in the side surface above 17 A of recessed parts located in the door outer edge side and upper direction among these recessed parts 17A-17D.

  As shown in FIG. 5, when the doors 3 and 4 are closed, the recesses 17A to 17D are inclined in a posture that becomes lower toward the back side (front of the vehicle in the present embodiment). And it functions as the water storage part 17 which stores water temporarily.

  In the present embodiment, as shown in FIG. 7, the recesses 17A and 17B are disposed on the door outer edge side, the recesses 17C and 17D are disposed on the door center side, and the discharge port 15 is disposed on the door outer edge side recess 17A. It is formed corresponding to.

  The recesses 17A to 17D are partitioned by partition walls 18a and 18b. The partition walls 18a and 18b are provided so as to intersect with each other in a substantially cross shape when viewed from the outside of the vehicle compartment (view of FIG. 7), and extend substantially perpendicular to the surface 3d on the vehicle interior side of the door inner panel 3b. Therefore, as shown in FIG. 5, when the doors 3 and 4 are closed, the partition walls 18a and 18b are stretched between the upper door 3 and the vehicle body 2 (the seal member 6 in the present embodiment), and the recesses 17A to 17A Even in the portion provided with 17D, the resilience of the sealing member 7 is more reliably ensured to improve the sealing performance. In addition, unevenness is appropriately provided on the side of the door inner panel 3b of the partition walls 18a and 18b, so that the passage of water between the recesses 17A to 17D and the support of the load by the partition walls 18a and 18b are more appropriately achieved. Also good.

  Further, the lower edges 17a of the openings of the recesses 17A to 17D are all inclined so that the door outer edge side is downward, and the water stored in the recesses 17A to 17D is kept away from the door center side. Yes. In the present embodiment, the lower end 17b of the lower edge 17a of the recesses 17A to 17D is all set above the intermediate wall 12, so that the water flowing out from the lower end 17b is trapped by the intermediate wall 12, and the intermediate It is made to flow down to the door outer edge side along the upper edge of the wall 12, and is discharged | emitted from the notch 8c.

  Further, a gap 9I is set between the end of the middle wall 12 on the door center side and the seal tape 11 as the standing wall 10, and when the flow rate of water flowing out from the recesses 17A to 17D is large, the gap 9I Water is allowed to flow downward and discharged from the notch 8d.

  In the structure of the recesses 17 </ b> A to 17 </ b> D as the water storage unit 17, water that has arrived from the discharge port 15 is first stored in the recess 17 </ b> A. When the amount of water is small, the water is stored only in the recess 17A. However, as the amount of water increases, water overflows from the recess 17A, and water is stored in the order of the recesses 17B, 17C, and 17D. In this embodiment, since the discharge port 15 is set above the recesses 17A and 17B on the door outer edge side, when the amount of water is small, the water can be stored only in the recesses 17A and 17B on the door outer edge side. Can be more reliably suppressed from entering the door center side.

  Moreover, in this embodiment, as shown in FIG. 7, the intermediate wall 12 is disposed at a position on the door center side (right side in FIG. 7) with respect to the notch 8c, and water coming from the door outer edge side is a gap. 9 is difficult to enter. That is, in the present embodiment, the intermediate wall 12 corresponds to the water shielding wall of the present invention.

  And the intermediate wall 12 as this water-impervious wall is arrange | positioned below the recessed part 17A-17D as the water storage part 17, and it inclines below toward the door outer edge side, and also as the standing wall 10 as mentioned above It functions.

  As shown in FIGS. 4, 6 and 7, the seal member 7 is provided with an outer wall portion 7b extending on the door outer edge side toward the vehicle interior side to shield the door outer edge side of the seal member 6 so as to seal the seal member. Water is more reliably suppressed from entering between 6 and 7 to the door center side.

  As described above, in this embodiment, the seal member 7 is attached to the surface 3d on the vehicle interior side of the door inner panel 3b along the peripheral edge 3e of the upper door 3, and the upper door 3 is attached to the seal member 7. In the closed state, the vertically extending portion 8 is set between the peripheral portion 3e of the door inner panel 3b and the peripheral portion 2c of the opening 2a of the vehicle body 2 and extending in the vertical direction. And the hollow part 8e is provided in this up-and-down extending part 8, the attachment part E containing the clip 13 is provided in the wall 8f by the side of the door inner panel 3b of the hollow part 8e, and the said fitting insertion hole 3c formed in the door inner panel 3b concerned The vertically extending portion 8 was fixed to the door inner panel 3b by inserting the clip 13 from the wall 8f side. Further, an inlet 14 for introducing water from the gap 9U between the vertically extending portion 8 and the door inner panel 3b into the hollow portion 8e is formed above the attachment portion E, and below the attachment portion E. In addition, a discharge port 15 for discharging water from the hollow portion 8e toward the gap 9 between the vertically extending portion 8 and the door inner panel 3b is formed, and discharged from the discharge port 15 below the attachment portion E. A water storage part 17 for storing fresh water was formed. Furthermore, in the gap 9 between the vertically extending portion 8 and the door inner panel 3b, a water conduit G for guiding water from the gap 9 toward the door outer edge side was formed.

  When a drainage path without a reservoir is provided in the gap between the seal member and the door inner panel, if a large amount of water temporarily arrives, the flow path is interrupted for almost the entire area from the upstream to the downstream of the drainage path. If the area is not increased, water may be unintentionally blocked and come out to the center side of the door. In this regard, according to the present embodiment, even when a large amount of water arrives temporarily, the water can be stored in the water storage unit 17, so that it is difficult to increase the cross-sectional area of the drainage path. Even if it exists, the flow volume of the water of the downstream side can be adjusted suitably with the water storage part 17, and it can suppress that water falls out to the door center side.

  Moreover, according to this embodiment, water is introduced into the hollow portion 8e, and the gap between the vertically extending portion 8 and the door inner panel 3b is a portion where the insertion insertion hole 3c is formed in the door inner panel 3b. 9M can be detoured and water can be prevented from entering the upper door 3 via the fitting insertion hole 3c of the door inner panel 3b. Further, in addition to the water storage portion 17 below the attachment portion E, the water can be stored in the hollow portion 8e as much as possible, so that the water storage volume can be secured larger and water can be more reliably suppressed from escaping to the door center side. . Therefore, according to the present embodiment, the structure in which the seal member 7 is fixed using the clip 13 and the structure in which water is temporarily stored in the seal member 7 can be more effectively achieved.

  Moreover, in this embodiment, recessed part 17A-17D which provided the opposing surface 8a with the door inner panel 3b of the up-and-down extending part 8 as the water storage part 17 in the side spaced apart from the said door inner panel 3b was formed. Therefore, the water reservoir 17 can be obtained with a relatively simple configuration.

  In the present embodiment, a plurality of recesses 17A to 17D are provided. Therefore, compared with the case where one large concave portion is provided, a decrease in rigidity of the portion where the concave portion is provided can be suppressed, and the sealing performance by the vertically extending portion 8 can be further enhanced.

  Moreover, in this embodiment, the water storage part 17 includes recesses 17A and 17B on the door outer edge side and recesses 17C and 17D on the door center side, and the discharge port 15 is located closer to the door outer edge side than the door center side recesses 17C and 17D. It was formed close to the recesses 17A and 17B. Therefore, since water can be preferentially stored in the recesses 17A and 17B on the door outer edge side away from the door center side, the water can be removed from the gap 9 between the vertically extending portion 8 and the door inner panel 3b from the door center side. It is possible to more reliably suppress the leakage to the vehicle interior side.

  In the present embodiment, the partition walls 18a and 18b extending substantially perpendicular to the surface 3d on the vehicle interior side of the door inner panel 3b are formed between the plurality of recesses 17A to 17D. Therefore, rigidity and resilience can be increased in the portion where the recessed portions 17A to 17D of the vertically extending portion 8 are formed, and the sealing performance at this portion can be increased.

  In the present embodiment, the door outer edge side of the lower edge 17a of the opening on the door inner panel 3b side of the recesses 17A to 17D is disposed below the door center side. Therefore, the water stored in the recesses 17A to 17D is moved away from the door center side and discharged to the door outer edge side, and the water passes from the gap 9 between the vertically extending portion 8 and the door inner panel 3b to the door center side and is Leakage to the indoor side can be more reliably suppressed.

  In the present embodiment, at least a part of the side wall of the water conduit G is formed by the standing wall 10 provided on the surface 8 a facing the door inner panel 3 b of the vertically extending portion 8. Therefore, with a relatively simple configuration, the required height can be secured in the gap 9 between the facing surface 8a of the vertically extending portion 8 and the surface 3d on the vehicle interior side of the door inner panel 3b, and the drainage can be improved. .

  Moreover, in this embodiment, the rib 8b is set up along the edge of the opposing surface 8a on the door outer edge side, and the notches 8c and 8d formed in the rib 8b are provided between the vertically extending portion 8 and the door inner panel 3b. The second discharge port 19 for discharging water from the gap 9 to the outer edge side of the door. Therefore, water can flow away from the door center side in the gap 9 and flow down along the door outer edge side, and water can flow from the gaps 9 and 9I between the vertically extending portion 8 and the door inner panel 3b to the door center side. It is possible to more reliably suppress leakage through the vehicle interior side.

  Moreover, in this embodiment, the intermediate wall 12 used as a water-impervious wall was provided in the position which becomes the door center side with respect to the notches 8c and 8d. Therefore, water enters the gap 9 between the vertically extending portion 8 and the door inner panel 3b from the notches 8c and 8d, and more reliably suppresses leakage from the gap 9 to the door center side and leaking to the vehicle interior side. can do.

  Further, in the present embodiment, the intermediate wall 12 functioning as a water shielding wall and a standing wall is disposed below the water storage portion 17 and inclined downward toward the door outer edge side. Therefore, the water overflowing from the water storage part 17 can flow away from the door center side toward the door outer edge side, and the water escapes from the gap 9 between the vertically extending part 8 and the door inner panel 3b to the door center side. Thus, leakage to the vehicle interior side can be more reliably suppressed.

  In the present embodiment, at least a part of the standing wall 10 (the intermediate wall 12 in the present embodiment) is formed of a water-absorbing material. Therefore, the water storage volume can be increased and the sealing performance can be further improved.

  Moreover, in this embodiment, between the inlet 14 and the attachment part E, it is in the up-and-down extension part 8, and the clearance gap 9M between the wall 8f by the side of the door inner panel 3b of the hollow part 8e and the said door inner panel 3b. A second impermeable wall 16 that suppresses water from entering is provided. Therefore, water that has arrived from above into the vertically extending portion 8 is reliably introduced through the introduction port 14 by the hollow portion 8e, and the vertically extending portion 8 and the door inner are formed at the portion where the insertion hole 3c is formed in the door inner panel 3b. The effect of suppressing the entry of water into the upper door 3 via the fitting insertion hole 3c of the door inner panel 3b can be obtained more reliably by bypassing the gap 9M between the panel 3b.

  Further, in the present embodiment, the lower edge 3a of the upper door 3 on the outer side of the upper edge 4a of the lower door 4 of the upper and lower doors 3 and 4 that closes the opening 2a on the rear surface of the vehicle body so as to be opened and closed. The seal member 7 is attached to the surface 3d of the door inner panel 3b of the upper door 3 on the vehicle interior side, and the vertically extending portion 8 is disposed above the upper edge portion 4a of the lower door 4. For this reason, in the peripheral part 2c of the opening part 2a, the clearance gap between the peripheral part 3e of the upper door 3 above the boundary part B and the opening part 2a of the vehicle body 2 which become large when two upper and lower doors 3 and 4 overlap. Can be blocked by the up-and-down extending portion 8 and water can be prevented from entering the door center side and thus the vehicle interior side from the gap.

  Further, in this embodiment, the gap between the lower edge 3 a of the upper door 3 and the upper edge 4 a of the lower door 4 is sealed by the longitudinal middle portion 7 a of the seal member 7, and both longitudinal ends of the seal member 7 are arranged. Is bent upward from the upper edge 4a of the lower door 4 to provide a vertically extending portion 8. Therefore, the sealing member 7 which continues from the lower edge 3a to the side edge of the upper door 3 can be formed, and the sealing performance can be enhanced. Moreover, compared with the case where the sealing member 7 and the up-and-down extending part 8 which seal the boundary part B are provided separately, while being able to reduce a number of parts, manufacturing effort can be reduced and manufacturing cost can be reduced. it can.

  In the present embodiment, the second seal member 6 straddling the boundary B of the upper door 3 and the lower door 4 is attached to the peripheral edge 2c of the opening 2a of the vehicle body 2, and the doors 3 and 4 are closed. Thus, the vertically extending portion 8 is brought into contact with the second seal member 6. That is, by providing the second seal member 6, the size of the gap between the peripheral edge portion 3 e of the upper door 3 and the peripheral edge portion 2 c of the opening 2 a is larger than when the seal member 7 is provided alone. The followability to the change can be improved, and thus the sealing property can be improved.

  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 structure in which the vertically extending portion provided in the seal member is in contact with another seal member is illustrated, but the present invention can also be applied when the vertically extending portion is in direct contact with the vehicle body.

  The structure according to the present invention can also be applied to a case where the opening is closed so as to be opened and closed with one door, and can also be applied to a portion extending vertically other than the corner portion of the door peripheral portion. It can also be applied to the opening on the side of the vehicle body.
