Description

Technical Field

[0001] The present invention relates to a sealing structure for vehicle doors. More specifically, it relates to a sealing structure for the front and rear doors of a center pillarless automobile.

Background Art

[0002] Conventionally, In a center pillarless automobile without a center pillar, the front door opens and closes left and right via a hinge provided on the front side, and the rear door is of a type that slides in the front-rear direction of the vehicle body to open and close.

[0003] In such a center pillarless automobile, in order not to let the water entering from the joint part of the front and rear doors fall to the indoor side, for example, as shown in FIGS. 21 and 22, a water receiving gutter (water receiver) 203 is formed in the weatherstrip 202 provided on the indoor side of the front door panel 201 (see, for example, FIGS. 5 and 6 of Patent Document 1). Here, the water W received by the receiving part 203a of the water receiving gutter 203 passes through the passage part 203b as it is, is guided through the drain hole 204 to the internal space (not shown) of the front door panel 201, and is discharged to the outside of the vehicle.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since the water receiving gutter 203 is provided integrally in a series so as to protrude inward from the inner side surface of the vehicle interior side wall of the weather strip 202, when providing an interior trim (not shown) on the vehicle interior side, it is necessary to set the shape so as not to interfere with the protruding water receiving gutter 203. Specifically, it was necessary to cut (cut off) the vicinity of the water receiving bucket at the rear end surface of the interior trim of the front door. Therefore, when looking at the cut portion from the rear to the front, there was a problem that a gap was generated between the interior trim and the water receiving gutter, deteriorating the appearance. Also, if the amount of protrusion of the water receiving gutter 203 inward of the vehicle is large, the gap between the front door weather strip and the interior trim becomes even larger, further deteriorating the appearance.

Effect of the Invention

[0014] According to the present invention, in a seal structure for a vehicle door in which a front type portion provided at the upper rear end of a front door and a rear type portion provided at the upper front end of a rear door elastically contact a main seal provided along the door opening edge of a body of a center pillarless automobile to seal a cut portion between the both doors, a water receiving gutter inclined on the vehicle interior side surface of the vehicle interior side wall of the front type portion and a water guiding bead inclined on the vehicle exterior side surface are provided, and an interior trim is provided on the vehicle interior side of the front type portion. The water receiving gutter is not continuously protruded inward of the vehicle from the front end portion to the rear end portion as in the conventional example, but a disappearing portion is provided in which a portion protruding inward of the vehicle is eliminated between the front end portion and the rear end portion, so that the portion where the rear end surface of the interior trim interferes can be reduced.

[0015] As a result, the amount of interior trim cut for interference countermeasures is reduced, so that the appearance is not deteriorated accordingly.

[0016] And, in the water receiving gutter, a first water receiving gutter for guiding water from the front end portion to the disappearing portion and a second water receiving gutter for guiding water to the rear end portion side are formed. The water flowing along the first water receiving gutter is guided to the water guiding bead through the first drain hole, and then is guided to the second water receiving gutter through the second drain hole and discharged to the outside of the vehicle from the rear end portion side, so that water is prevented from entering the vehicle interior.

[0017] Also, according to the present invention, a hollow seal portion that extends vertically is provided behind the front type portion and elastically contacts the front side of the rear door when both doors are closed. A third drain hole is provided that penetrates from the inner side surface of the inner side wall of the front type portion into the hollow seal portion so as to guide the water guided to the second water receiving gutter into the hollow seal portion, and is discharged to the outside of the vehicle from the hollow seal portion, so that the water conductivity can be ensured.

[0018] Also, according to the present invention, the water receiving gutter is composed of a bottom wall and a vertical wall having a substantially L-shaped configuration, so that water surely flows inside the water receiving gutter and the possibility of overflowing therefrom is low. Also, the disappearing portion is configured by bending the vertical wall of the first water receiving barrel outward of the vehicle at a position in front of the rear end portion and connecting and integrating it with the inner side surface of the inner side wall of the front type portion, so that the structure is simple. Also, the first drain hole is provided at a height position below the upper end of the vertical wall of the first water receiving gutter at a position in front of the disappearing portion, the second drain hole is provided at a height position below the upper end of the vertical wall of the second water receiving gutter at a position behind the disappearing portion, and the third drain hole is provided at a height position below the upper end of the vertical wall of the second water receiving gutter at the connection position with the hollow seal portion. Therefore, water is smoothly discharged to the outside of the vehicle through the water receiving gutter, and it is possible to prevent water from overflowing or splashing from the water receiving gutter on the way.

[0019] Further, according to the present invention, water flowing along the water guide bead provided on the outer side surface of the inner side wall of the front type portion is directly guided into the hollow seal portion through, for example, the fourth drain hole and discharged to the outside of the vehicle without returning from the outside of the vehicle to the inside of the vehicle. Therefore, it is not necessary to provide the second drain hole penetrating from the outer side surface of the inner side wall of the front type portion to the inner side surface of the inner side wall of the vehicle. In addition, the water flowing into the second water receiving gutter of the water receiving gutter is guided into the hollow seal portion through, for example, the third drain hole and discharged to the outside of the vehicle, so that the water does not overflow.

[0020] Further, according to the present invention, the appearance is improved because the interior trim is not cut at the part of the interior trim that covers the disappearing part of the water receiving gutter from the inside of the vehicle.

[0022] With reference to the drawings, the seal structure of a vehicle door according to an embodiment of the present invention will be described.

[0023] The seal structure of the vehicle door according to the embodiment of the present invention is applied to a center pillarless automobile 100 as shown in FIG. 1. The front door 120 opens and closes left and right via a hinge provided on the front side, and the rear door 140 slides in the front-rear direction of the vehicle body to open and close. It relates to the seal structure of the upper parting part between the two doors 120 and 140.

[0024] As shown in FIGS. 1 and 2, when the front door 120 and the rear door 140 are closed, they are elastically contacted with the main seal 80 provided along the door opening edge 110 of the body. At the upper part of the parting part between the two doors 120 and 140, the front type part 40 provided at the upper rear end of the front door 120 and the rear type part 60 provided at the upper front end of the rear door 140 are elastically contacted to seal between the two doors 120 and 140. In addition, the front type part 40 and the rear type part 60 are also elastically contacted with the main seal 80 to seal between the body and the door opening edge 110. The front type part 40 is provided so as to extend vertically on the rear side of the front door 120 and is formed at the upper end of the hollow seal part 54 that elastically contacts the front side of the rear door 140 when the doors 120 and 140 are closed (the illustration of the elastic contact state is omitted).

[0025] As shown in FIG. 1, above the main seal 80 at the upper part of the door opening edge 110 of the body, an upper parting seal 95 (the illustration of the cross-sectional shape is omitted) that elastically contacts the two doors 120 and 140 respectively when the two doors 120 and 140 are closed is provided.

[0026] The front - type part 40 has a shape as shown in FIGS. 2 to 4 and FIG. 7, and a front water - receiving concave part 43 that opens upward is provided at its upper part. The front water - receiving concave part 43 is surrounded by an in - vehicle side water - stop wall 44, an out - vehicle side water - stop wall 45, a rear - side water - stop wall 46, and a front - side water - stop wall 47 that stand upright upward. The bottom wall 48 is slightly inclined so as to descend from the rear side to the front side of the vehicle. A front notch part 49 is provided on the front - side water - stop wall 47 side of the out - vehicle side water - stop wall 45, and the water led to the front water - receiving concave part 43 from the elastic contact part between the front - type part 40 and the rear - type part 60 etc. is discharged to the out - vehicle side (FW1→FW2→FW3).

[0027] Here, as shown in FIGS. 14 to 16, the main seal 80 is attached to the door opening edge 110 of the body, and when the front door 120 is closed, it elastically contacts the in - vehicle side surface 41a of the in - vehicle side wall 41 of the front - type part 40. Similarly, when the rear door 140 is closed, the main seal 80 elastically contacts the in - vehicle side wall 61 of the rear - type part 60 (illustration is omitted). Here, the height position at approximately the center of the elastic contact position between the in - vehicle side surface 41a of the in - vehicle side wall 41 of the front - type part 40 and the main seal 80 is defined as the seal line SL, and the height position at approximately the center of the elastic contact position between the in - vehicle side wall 61 of the rear - type part 60 and the main seal 80 is also defined as the seal line SL.

[0028] Also, as shown in FIG. 3, below the seal line SL with the main seal 80 and below the lower part of the front notch part 49 on the out - vehicle side surface 41b of the in - vehicle side wall 41 of the front - type part 40, a front lower - side water - guiding bead 52 that inclines downward more toward the rear side is provided. The front lower - side water - guiding bead 52 is configured to receive the water (FW3) that drops to the out - vehicle side from the front notch part 49.

[0029] Also, as shown in FIGS. 2, 4, and 7, a water receiving gutter 55 that inclines downward more toward the rear side is provided below the seal line SL with the main seal 80 at the lower part of the in - vehicle side surface 41a of the in - vehicle side wall 41 of the front - type part 40.

[0030] Next, the rear type part 60 has a shape as shown in FIGS. 2, 5 to 7, and a rear water receiving recess 63 that opens upward is provided at its upper part. The rear water receiving recess 63 is surrounded by an inner vehicle side water stop wall 64, an outer vehicle side water stop wall 65, a front side water stop wall 66, and a rear side water stop wall 67 that are erected upward, and the bottom wall 68 is slightly inclined so as to descend from the front side to the rear side of the vehicle. A rear notch 69 is provided on the rear side water stop wall 67 side of the outer vehicle side water stop wall 65, and water led to the rear water receiving recess 63 from the elastic contact part between the front type part 40 and the rear type part 60 and the like is discharged to the outside of the vehicle from between the rear door 140 (RW1→RW2→RW3).

[0031] Also, as shown in FIG. 5, below the seal line SL with the main seal 80 and below the lower part of the rear notch 69 on the outer vehicle side surface 62 of the rear type part 60, a rear lower water guiding bead 71 that is inclined downward toward the front side is provided. The rear lower water guiding bead 71 is adapted to receive water (RW3) that falls from the rear notch 69 to the outside of the vehicle. Further, the water (RW4) flowing along the rear lower water guiding bead 71 is discharged to the front of the outside of the vehicle.

[0032] Also, as shown in FIGS. 2, 6, and 7, a water receiving gutter 72 that is inclined downward toward the center side and below the seal line SL with the main seal 80 is also provided at the lower part of the inner vehicle side surface 61 of the rear type part 60, and a drain hole 73 is provided at the lower end of the water receiving gutter 72.

[0033] Then, as shown in FIGS. 4 and 7, the rear side surface 46a of the rear side water stop wall 46 of the front water receiving recess 43 in the front type part 40 is inclined such that the upper side is located in front of the lower side and, as shown in FIG. 2, the outside of the vehicle is located in front of the inside of the vehicle. Also, as shown in FIGS. 6 and 7, the front side surface 66a of the front side water stop wall 66 of the rear water receiving recess 63 in the rear type part 60 is also inclined such that the upper side is located in front of the lower side and, as shown in FIG. 2, the outside of the vehicle is located in front of the inside of the vehicle.

[0034] When the front door 120 and the rear door 140 are closed, the rear surface 46a of the rear water-stop wall 46 of the front water-receiving recess 43 and the front surface 66a of the front water-stop wall 66 of the rear water-receiving recess 63, which are formed to be inclined in this way, are elastically contacted with each other as shown in FIGS. 2 and 7. In this embodiment, since the hinge-type front door 120 is first closed and then the slide-type rear door 140 is closed, the front surface 66a of the front water-stop wall 66 of the rear water-receiving recess 63 in the rear-type portion 60 provided at the upper part on the vehicle front side of the rear door 140 approaches and elastically contacts the rear surface 46a of the rear water-stop wall 46 of the front water-receiving recess 43 in the front-type portion 40 of the front door 120 that has been closed first from the outside of the vehicle.

[0035] At this time, the elastic contact position between the rear surface 46a of the rear water-stop wall 46 of the front water-receiving recess 43 and the front surface 66a of the front water-stop wall 66 of the rear water-receiving recess 63 is set at a position lower than the position of the upper parting seal 95 and higher than the position of the main seal 80. Moreover, the upper end of the rear surface 46a is set at a position lower than the upper end of the front surface 66a. The main seal 80 elastically contacts the inner side surface 41a of the inner side wall 41 of the front-type portion 40 at the elastic contact position between the rear surface 46a of the rear water-stop wall 46 of the front water-receiving recess 43 and the front surface 66a of the front water-stop wall 66 of the rear water-receiving recess 63. Also, on the vehicle front side of the elastic contact position, it also elastically contacts the inner side surface 41a of the inner side wall 41 of the front-type portion 40, but on the vehicle rear side of the elastic contact position, it elastically contacts the inner side surface 61 of the rear-type portion 60 and above the water receiving gutter 72.

[0036] The seal line SL showing the elastic contact positions between the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40 and the main seal 80, and between the inner side surface 61 of the rear type portion 60 and the main seal 80 is shown in FIGS. 2 and 7. First, since the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40 needs to be switched so that the sealing object becomes only the front door 120 on the front side of the seal line SL, it is necessary to gradually reduce the thickness in the vehicle left-right direction and make the thickness zero at the front end to disappear. Therefore, the front water receiving recess 43 provided directly above the seal line SL can only be set up to the front of the front end of the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40. However, in the front type portion 40 which is considerably lower than the seal line SL, since there is no restriction on the thickness in the vehicle left-right direction, the water receiving bucket 55 can be set up to a position in front of the front end of the front water receiving recess 43. As a result, the water leakage (FW5) from the portion on the front side of the front water receiving recess 43 is stopped at the seal line SL showing the elastic contact position between the front type portion 40 and the main seal 80. However, even if there is water leakage (FW5) that cannot be completely stopped at the seal line SL, it can be received by the water receiving bucket 55, and the water (FW6) flowing along the water receiving bucket 55 can be drained into the hollow seal portion 54. Also, as shown in FIGS. 2 and 3, on the outside of the vehicle of the front type portion 40 as well, similar to the inside of the vehicle, the front lower water guiding bead 52 can be set up to a position in front of the front notch portion 49. Therefore, even if there is water leakage (FW7) from the portion on the front side of the front notch portion 49, it can be received by the front lower water guiding bead 52 and guided into the hollow seal portion 54.

[0037] Similarly, as shown in FIGS. 2 and 7, since the inner side surface 61 of the rear type portion 60 needs to be switched so that the sealing object is only the rear door 140 on the rear side of the seal line SL, it is necessary to gradually reduce the thickness in the vehicle left - right direction and make the thickness zero at the rear end to disappear. Therefore, the rear water receiving recess 63 provided directly above the seal line SL can only be set up to in front of the rear end of the inner side surface 61 of the rear type portion 60. However, in the rear type portion 60 which is considerably lower than the seal line SL, since there is no restriction on the thickness in the vehicle left - right direction, the water receiving bucket 72 can be set up to a position behind the rear end of the rear water receiving recess 63. As a result, the water leakage (RW5) from the part behind the rear water receiving recess 63 is stopped at the seal line SL indicating the elastic contact position between the rear type portion 60 and the main seal 80. Even if there is water leakage (RW5) that cannot be completely stopped at the seal line SL, it can be received by the water receiving bucket 72, and the water (RW6) flowing along the water receiving bucket 72 can be drained to the outside of the vehicle through the drain hole 73 provided at the bottom of the water receiving bucket 72. More specifically, as shown in FIG. 5, the drain hole 73 penetrates the rear type portion 60, and since the rear lower water guiding bead 71 is arranged below the drain hole 73, the water (RW6) flowing along the water receiving bucket 72 falls from the drain hole 73 and is received by the rear lower water guiding bead 71. Also, as shown in FIGS. 2 and 5, on the outside of the vehicle of the rear type portion 60, similar to the inside of the vehicle, the rear lower water guiding bead 71 can be set up to a position behind the rear notch portion 69. Therefore, even if there is water leakage (RW7) from the part behind the rear notch portion 69, it can be received by the rear lower water guiding bead 71 and drained to the outside of the vehicle.

[0038] Here, the water receiving bucket 55 provided on the inner side surface 41a of the inner side wall 41 of the front type portion 40 is inclined so as to descend from the front end portion 55M to the rear end portion 55U, but it is not continuously provided. As shown in FIGS. 2, 4, 7, 8 and 17, a disappearing portion S is formed which eliminates the portion protruding inward of the vehicle in front of the rear end portion 55U between the front end portion 55M and the rear end portion 55U. And a first water receiving trough 55A for guiding water from the front end portion 55M to the disappearing portion S and a second water receiving trough 55D for guiding water to the rear end portion 55U side are formed.

[0039] As shown in FIGS. 8 and 17, the water receiving gutter 55 has a substantially L-shaped configuration formed by bottom walls 55B and 55E that extend substantially horizontally inward from the inner side surface 41a of the inner side wall 41 of the front type portion 40, and vertical walls 55C and 55F that extend upward from the inner side ends of the bottom walls 55B and 55E. The first water receiving tub 55A located above the disappearing portion S is composed of the bottom wall 55B and the vertical wall 55C extending from the inner side end thereof, and the second water receiving tub 55D located below the disappearing portion S is composed of the bottom wall 55E and the vertical wall 55F extending from the inner side end thereof. Also, the disappearing portion S is configured by bending the vertical wall 55C of the first water receiving tub 55A outward at a position in front of the rear side end portion 55U and connecting and integrating it with the inner side surface 41a of the inner side wall 41 of the front type portion 40. Also, the rear side of the vertical wall 55F of the second water receiving tub 55D provided on the rear side of the disappearing portion S is bent outward at a position in front of the rear side end portion 55U and is connected and integrated with the inner side surface of the hollow seal portion 54. Also, the front side of the vertical wall 55F of the second water receiving tub 55D provided on the rear side of the disappearing portion S is bent outward at a position in front of the rear side end portion 55U and is connected and integrated with the rear end 41U of the inner side surface 41a of the inner side wall 41 of the front type portion 40.

[0040] In addition, in the present embodiment, as shown in FIGS. 9 to 13, a flange F is disposed where the rear end portions of the inner panel 120A and the outer panel 120B of the front door 120 are joined (hemmed). Also, the front type portion 40 has an inner side wall 41 and an outer side wall 42. The inner side wall 41 and the outer side wall 42 are provided so as to sandwich the front door 120, and the inner side wall 41 and the outer side wall 42 are connected at the rear end of the flange F. Further, on the outer side of the outer side wall 42, a hollow seal portion 54 that elastically contacts the rear type portion 60 when the door is closed is disposed (a cross-sectional view showing the elastic contact state is not shown).

[0041] Then, as shown in FIGS. 11, 14, 17, and 18, at a height position below the upper end of the vertical wall 55C of the first water receiving gutter 55A at a position in front of the disappearing portion S in the front type portion 40, a first drain hole H1 penetrating from the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40 to the outer side surface 41b is provided. As a result, as shown in FIGS. 7 to 10, the water (FW6) flowing along the first water receiving gutter 55A from the front end portion 55M of the water receiving gutter 55 is guided to the water guiding bead 52 through the first drain hole H1 as shown in FIGS. 11 and 14. In FIG. 14, the height positions of the upper side surface of the bottom wall 55B of the first water receiving gutter 55A, the upper side surface 52a of the root portion of the water guiding bead 52, and the lower side surface of the first drain hole H1 are set to the same height position. However, as long as the water (FW6) in the first water receiving gutter 55A is guided to the water guiding bead 52 through the first drain hole H1, the above three height positions do not necessarily have to be the same height position.

[0042] The water (FW8) guided to the water guiding bead 52 through the first drain hole H1 merges with the water (FW4) flowing from the front end portion of the water guiding bead 52 and flows to the rear end portion as shown in FIG. 18. The water (FW9) flowing to the rear end portion is guided to the second water receiving gutter 55D of the water receiving gutter 55 through the second drain hole H2 penetrating from the outer side surface 41b of the vehicle interior side wall 41 of the front type portion 40 to the inner side surface 41a of the vehicle interior side wall 41 at the position of the rear end portion of the water guiding bead 52 as shown in FIGS. 12, 17, and 18. The second drain hole H2 is provided at a height position below the upper end of the vertical wall 55F of the second water receiving gutter 55D at a position behind the disappearing portion S. Here, the height positions of the upper side surface 52a of the root portion of the water guiding bead 52, the lower side surface of the second drain hole H2, and the upper side surface of the bottom wall 55E of the second water receiving gutter 55D may be set to the same height position. However, as long as the water (FW9) on the water guiding bead 52 is guided to the second water receiving gutter 55D through the second drain hole H2, the above three height positions do not necessarily have to be the same height position.

[0043] The water (FW9) guided to the second water receiving gutter 55D is guided into the hollow seal portion 54 through the third drain hole H3 that penetrates into the hollow seal portion 54 from the rear end 41U of the inner side surface 41a of the inner side wall 41 of the front type portion 40 of the vehicle interior, as shown in FIGS. 13, 16, and 17. The water (FW10) guided into the hollow seal portion 54 falls through the hollow seal portion 54 and is discharged to the outside of the vehicle. The third drain hole H3 is provided at a height position below the upper end of the vertical wall 55F of the second water receiving gutter 55D at the connection position with the hollow seal portion 54 in the second water receiving gutter 55D. Here, the height position of the upper side surface of the bottom wall 55E of the second water receiving gutter 55D and the height position of the lower side surface of the third drain hole H3 may be set to the same height position. However, since it is only necessary that the water (FW9) on the second water receiving gutter 55D is guided into the hollow seal portion 54 through the third drain hole H3, the above two height positions do not necessarily have to be the same height position.

[0044] Here, if the water receiving tub 55 is continuously provided from the front end portion 55M to the rear end portion 55U, the protruding amount of the water receiving gutter 55 protruding from the front type portion 40 to the vehicle interior side becomes large. Therefore, when the interior trim NT is provided from the vehicle interior side, as shown in FIG. 20, the rear side of the water receiving gutter 55 protrudes significantly from the interior trim NT, and the rear end surface NTBE of the interior trim NT that interferes with the water receiving gutter 55 needs to be cut significantly, resulting in a poor appearance.

[0045] On the contrary, in the present embodiment, the portion where the interior trim NT interferes with the first water receiving gutter 55A of the water receiving gutter 55 is reduced by providing the disappearing portion S (in other words, the water receiving gutter 55 does not exist in the disappearing portion S). Therefore, as shown in FIG. 19, the protruding amount of the second water receiving gutter 55D protruding from the interior trim NT can be reduced, and the cutting amount of the rear end surface NTBE of the interior trim NT can also be reduced.

[0046] According to the seal structure of the vehicle door configured as described above, the front - type portion 40 provided at the upper rear end of the front door 120 and the rear - type portion 60 provided at the upper front end of the rear door 140 elastically contact the main seal 80 provided along the door opening edge 110 of the body of the center - pillar - less automobile 100 to seal the gap between the two doors 120 and 140. On the inner - side wall 41 of the front - type portion 40, a water receiving trough 55 inclined on the inner - side surface 41a of the vehicle interior and a water guiding bead 52 inclined on the outer - side surface 41b of the vehicle interior of the inner - side wall 41 are provided. Further, an interior trim NT is provided on the inner - side of the front - type portion 40. In the seal structure of the vehicle door, the water receiving trough 55 does not continuously project inward from the front - side end portion 55M to the rear - side end portion 55U as in the conventional example, but a disappearing portion S with no projecting portion inward is provided between the front - side end portion 55M and the rear - side end portion 55U. Therefore, the portion where the rear - end surface NTBE of the interior trim NT interferes can be reduced, and thus the amount of cutting of the rear - end surface NTBE of the interior trim NT for interference countermeasures is reduced, and accordingly, the appearance is not deteriorated.

[0047] Also, in the water receiving trough 55, a first water receiving trough 55A for guiding water from the front - side end portion 55M to the disappearing portion S and a second water receiving trough 55D for guiding water to the rear - side end portion 55U side are formed. The water flowing along the first water receiving trough 55A is guided to the water guiding bead 52 through the first drain hole H1, and then is guided to the second water receiving trough 55D through the second drain hole H2 and discharged to the outside of the vehicle from the rear - side end portion 55U side. Therefore, water intrusion into the vehicle interior is prevented.

[0048] Also, a hollow seal portion 54 extending vertically is provided on the rear - side of the front - type portion 40 and elastically contacting the front - side of the rear door 140 when the two doors 120 and 140 are closed. A third drain hole H3 penetrating from the inner - side surface 41a of the inner - side wall 41 of the front - type portion 40 into the hollow seal portion 54 is provided to guide the water guided to the second water receiving trough 55D into the hollow seal portion 54 and discharged to the outside of the vehicle from the hollow seal portion 54. Therefore, water conductivity can be ensured.

[0049] In this embodiment, the water flowing along the first water receiving gutter 55A of the water receiving gutter 55 is guided from the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40 to the outer side surface 41b of the vehicle interior side wall 41 through the first drain hole H1, flows along the water guiding bead 52, is guided from the outer side surface 41b of the vehicle interior side wall 41 to the inner side surface 41a of the vehicle interior side wall 41 through the second drain hole H2, flows into the second water receiving gutter 55D, and is guided into the hollow seal portion 54 through the third drain hole H3 and discharged to the outside of the vehicle. However, instead of finally guiding it into the hollow seal portion 54, similar to the conventional example (Figs. 21 and 22), the water flowing along the first water receiving gutter 55A of the water receiving gutter 55 is guided from the inner side surface 41a of the vehicle interior side wall 41 of the front type portion 40 to the outer side surface 41b of the vehicle interior side wall 41 through the first drain hole H1, and then further guided into the front door 120 and discharged to the outside of the vehicle. In this case, it is necessary to provide a hole for guiding water into the front door 120.

[0050] Also, instead of guiding the water guided to the water guiding bead 52 from the outer side surface 41b of the vehicle interior side wall 41 of the front type portion 40 to the inner side surface 41a of the vehicle interior side wall 41 through the second drain hole H2, the water guided to the water guiding bead 52 may be directly guided to the hollow seal portion 54, and the water flowing into the second water receiving gutter 55D may be guided into the hollow seal portion 54 through the third drain hole H3 and discharged to the outside of the vehicle. In this case, a fourth drain hole (not shown) for directly guiding the water guided to the water guiding bead 52 to the hollow seal portion 54 is required. This also varies depending on the mounting method of the hollow seal portion 54 to the front door 120. For example, when the flange F of the front door 120 exists between the outer side wall 42 of the vehicle and the water guiding bead 52, instead of providing the second drain hole H2 shown in Figs. 12 and 13, a fifth drain hole is formed in the flange F (not shown), and when the flange F does not exist, a fourth drain hole is formed in the outer side wall 42 of the vehicle separately from the third drain hole H3 without forming the fifth drain hole.

[0051] Note that the seal structure for the vehicle door according to this embodiment is applied to the upper parting portion of the front hinge-opening front door 120 and the slide-type rear door 140 in the center-pillarless automobile 100. However, it is also applicable to the double-leaf hinge-opening doors where both the front door and the rear door are hinge-opening type, or the double-leaf sliding doors where both the front door and the rear door slide in the front-rear direction. In addition, the vehicle outer water-stop walls 45 and 65 may be attached to the front door or the rear door with double-sided tape, clips, etc. as required. Also, the front-type portion and the rear-type portion are made of a rubber-like elastic body and only need to have appropriate rigidity. Rubber materials such as EPDM and thermoplastic resin materials such as TPO are applicable. The material may be a non-foamed material or a foamed material.
