Description

  The present invention relates to a seal structure of a portion where a first front end portion of a hinge door, a second front end portion of a slide door, and a main weather strip at a body opening edge portion are combined in a center pillarless automobile.

  Conventionally, in a center pillarless vehicle, there is an automobile configured such that each of the hinge door and the slide door is movable independently, the hinge door is coupled by the hinge, and is rotated to open and close, and the slide door is opened and closed by the slide mechanism. To do.

  A main weather strip 207 shown in FIG. 7A is installed as a main seal for the purpose of waterproofing the interior of the body of this type of automobile, but there is a space between the hinge door 101 and the slide door 102. As a result, water leakage occurs. In order to avoid this water leakage, the seal member 201 and the seal member 202 are respectively installed on the upper portion of the first tip portion 101a of the hinge door 101 and the second tip portion 102a of the slide door 102 to form a seal surface. The

JP 2005-186647 A (published July 14, 2005) Japanese Patent No. 4128421 (registered on May 23, 2008) JP, 2006-000565, A (January 7, 2016 publication)

  However, in the above-described prior art, the seal surface is transferred from the hinge door 101 to the seal member 201, transferred from the seal member 201 to the seal member 202, and transferred from the seal member 202 to the slide door 102. There is a problem that a minute gap is generated between the weather strip 207 and the sealing surface. In addition, water oozes out of the minute gap due to long-term rainfall or the like, causing a problem of water leakage.

  Further, in the above-described prior art, an opening / closing locus of the slide door 102 is located immediately below the mating portion 203 which is a transfer portion of the seal member 201 of the hinge door 101 and the seal member 202 of the slide door 102 shown in FIG. Cannot set the water receiver described later. Therefore, the water that has oozed out from the mating portion 203 of each sealing member of the hinge door 101 and the slide door 102 becomes water leakage into the vehicle. In FIG. 7B, the seal member 201 is shown in a perspective view as seen from the rear obliquely upper side, and the seal member 202 is shown in a front view as seen from the vehicle inner side.

  Further, in the seal structure described in Patent Document 1, although the guide ribs are provided at the end of each of the two seal members (not shown), the point that the water receiver cannot be set immediately below the mating portion of each seal member is as described above. This is the same as the prior art. For this reason, also in the seal structure described in Patent Document 1, water that oozes from the mating portion of each seal member leaks into the vehicle.

  The present invention has been made in view of the above-described problems. The object of the present invention is to remove water that oozes out from the portion where the hinge door, the sliding door, and the seal members of the body opening edge are combined with the first protruding wall. An object of the present invention is to realize a seal structure that can stably drain water by causing a minute gap formed in a region surrounded by a curved wall and a hollow seal portion of a main weather strip to protrude forward from a water receiver.

  In order to solve the above problems, a seal structure according to an aspect of the present invention includes a first front end portion of a hinge door, a second front end portion of a slide door, and a main weather strip at a body opening edge in a center pillarless automobile. In the sealing structure of the mating portion, a first seal member is installed above the first tip portion, a second seal member is installed above the second tip portion, and the first seal member The first inner wall disposed on the inner side of the vehicle and the second inner wall elastically contacting the second seal member are connected via a first curved wall curved so as to protrude toward the second seal member. In the second seal member, the third inner wall disposed on the inner side of the vehicle and the second curved wall that is curved in elastic contact with the first seal member are tapered toward the first seal member. Part A tip projecting wall projecting to the front side of the lower portion of the connecting portion is provided at an upper portion of the connecting portion, and the first curved portion is closed in a state where each of the hinge door and the sliding door is closed. A minute gap is formed in a region surrounded by the wall, the tip protruding wall, and the hollow seal portion of the main weather strip.

  According to the said structure, the front-end | tip protrusion wall which protrudes in the front side rather than the lower part of the said connection part is provided in the upper part of the connection part of the 2nd seal member. For this reason, when there is no tip protruding wall, the position of the minute gap formed in the region surrounded by the connection portion of the second seal member, the first curved wall of the first seal member, and the hollow seal portion of the main weather strip. In addition, the position of the minute gap formed in the region surrounded by the tip protruding wall, the first curved wall, and the hollow seal portion of the main weather strip is shifted to the front side. Further, the water that oozes out from the portion where the hinge door and the sliding door and the seal members of the body opening edge are joined flows downward through a minute gap.

  Therefore, the water that oozes out from the portion where the seal members of the hinge door, the slide door, and the body opening edge are combined is formed in a region surrounded by the tip protruding wall, the first curved wall, and the hollow seal portion of the main weather strip. By allowing the gap to protrude forward from the water receiver, the water can be drained stably.

  In the seal structure according to one aspect of the present invention, a guide rib that guides water flowing downward through the minute gap to a water receiver provided in the first seal member is provided on the first inner wall. Is preferred. According to the above configuration, by appropriately setting the size and arrangement direction of the guide rib, the water flowing downward through the minute gap can be reliably guided by the water receiver through the guide rib.

  Further, in the seal structure according to one aspect of the present invention, the extending direction of the guide rib is in the horizontal direction, and the inclined direction of the rear portion from the drain hole for draining the water out of the vehicle in the water receiver. It is preferable that they are inclined in the same direction.

  According to the above configuration, even when the front and rear of the vehicle are inclined, it is possible to suppress the water flowing downward through the minute gap from flowing to the rear side.

  In the seal structure according to one embodiment of the present invention, the drain hole is preferably formed in the water receiver. According to the said structure, the water which reaches the bottom of a water receiver can be discharged | emitted outside a vehicle through a drain hole.

  In the seal structure according to an aspect of the present invention, it is preferable that a step is provided on the first inner wall to prevent water flowing downward through the minute gap from flowing to the rear side. According to the above configuration, the water flowing downward through the minute gap can be prevented from flowing to the rear side due to the presence of the step.

  According to the seal structure according to one aspect of the present invention, water that oozes out from a portion where the seal members of the hinge door, the slide door, and the body opening edge are joined together, and the hollow seal of the tip protruding wall, the first curved wall, and the main weather strip. By causing the minute gap formed in the region surrounded by the part to protrude forward from the water receiver, there is an effect that water can be discharged stably.

[Outline of Seal Structure According to Embodiment 1]
As shown to (a) of FIG. 1, the 1st seal member 1 is installed in the upper part of the 1st front-end | tip part 101a of the hinge door 101. As shown in FIG. The first seal member 1 is a weather strip for ensuring a sealing property between the first seal member 1 and the main weather strip 7 by elastic contact with the main weather strip 7.

  On the other hand, the second seal member 2 is installed on the upper portion of the second tip end portion 102 a of the slide door 102. The second seal member 2 is a weather strip for ensuring a sealing property between the second seal member 2 and the main weather strip 7 by elastic contact with the main weather strip 7. In FIG. 1A, the first seal member 1 is shown in a perspective view seen from the rear side obliquely upward, and the second seal member 2 is shown in a front view seen from the vehicle interior side.

  As a molding material for the first seal member 1 and the second seal member 2, an elastic body such as synthetic rubber or TPE (thermoplastic elastomer) is used. For synthetic rubber, EPDM (ethylene propylene diene copolymer rubber) or the like is used, and for TPE (thermoplastic elastomer), TPO (olefinic thermoplastic elastomer) or the like is used. Further, the elastic body to be used may be a foam material or a non-foam material. Further, for the purpose of securing rigidity, a core material made of metal or hard rigid resin may be embedded in the elastic body.

  As shown in (c) and (d) of FIG. 1, for the first seal member 1, the first inner wall 11 disposed on the vehicle inner side and the second inner wall 12 elastically contacting the second seal member 2 are It is connected via a first curved wall 13 that is curved so as to be convex toward the second seal member 2 side.

  As for the second seal member 2, the third inner wall 21 disposed on the inner side of the vehicle and the second curved wall 22 that is curved in elastic contact with the first seal member 1 approach the first seal member 1. Is connected through a connection portion 23 that becomes narrower.

  1 (c) and 1 (d) are respectively before and after the second inner wall 12 and the second seal member 2 are elastically contacted, or before and after the second curved wall 22 and the first seal member 1 are elastically contacted. Indicates the state.

  As shown in FIG. 1D, the second curved wall 22 and the second inner wall 12 are in elastic contact with each other, whereby the second curved wall 22 is elastically deformed, and the second curved wall 22 is in close contact with the second inner wall 12. . Thereby, the sealing performance between the 2nd curved wall 22 and the 2nd inner wall 12 is ensured.

  FIGS. 1E and 1F show states before and after the second inner wall 12 and the second seal member 2 are elastically contacted or before and after the second curved wall 22 and the first seal member 1 are elastically contacted, respectively. ing. As shown in FIG. 1 (f), the second curved wall 22 and the second inner wall 12 are elastically contacted, whereby the second curved wall 22 is elastically deformed, and the second curved wall 22 is in close contact with the second inner wall 12. . Thereby, the sealing performance between the 2nd curved wall 22 and the 2nd inner wall 12 is ensured.

  Next, as shown in FIGS. 1A and 1D, a tip protruding wall 2 a that protrudes to the front side of the lower portion of the connecting portion 23 is provided at the upper portion of the connecting portion 23. Further, as shown in the partial enlarged view surrounded by the broken-line circle in FIG. 1D, a minute gap 3a is formed between the first curved wall 13 and the tip protruding wall 2a. Further, the gap 3a is connected in the vertical direction to form a minute gap 3 (see also FIG. 1A).

  In a state where the hinge door 101 and the slide door 102 are closed, a minute gap 3 is formed in a region surrounded by the first curved wall 13, the tip protruding wall 2 a, and the hollow seal portion 7 a of the main weather strip 7.

  The position where the minute gap 3 is formed is shifted to the front side from the position of the minute gap formed between the connecting portion 23 and the first curved wall 13 when there is no tip protruding wall 2a. At this time, the water that oozes out from the portion where the seal members of the hinge door 101, the slide door 102, and the body opening edge portion 100h are combined passes through the upper side of the elastic contact portion between the first curved wall 13 and the connection portion 23, and then the front side To the position where the gap 3a is formed.

  The gap 3a is formed at a position on the front side of the rear end position of the water receiver 5 so that the water receiver 5 can receive water flowing downward through the minute gap 3. Further, as shown in FIG. 1A, the minute gap 3 is continuous from the front-side upper end of the third inner wall 21 to directly above the rear-side end of the water receiver 5.

  For this reason, the water that oozes out from the portion where the seal members of the hinge door 101, the slide door 102, and the body opening edge portion 100h are joined together is the formation position of the gap 3a from the upper side of the elastic contact portion between the first curved wall 13 and the connection portion 23. Flows up. That is, the water that oozes out from the portion where the seal members of the hinge door 101, the slide door 102, and the body opening edge portion 100h are combined flows more to the front side than the elastic contact portion between the first curved wall 13 and the connecting portion 23. Further, the water that has reached the gap 3 a flows downward through the minute gap 3 and is guided to the water receiver 5 that exists immediately below the minute gap 3.

  As described above, the water that oozes out from the portion where the seal members of the hinge door 101, the slide door 102, and the body opening edge portion 100h are combined passes through the upper side of the elastic contact portion between the first curved wall 13 and the connecting portion 23. It flows to the formation position of 3a. In addition, the water that has reached the gap 3 a flows downward along the minute gap 3, thereby being guided to the water receiver 5 installed on the first inner wall 11.

  As a result, water that oozes out from a portion where the seal members of the hinge door 101, the slide door 102, and the body opening edge portion 100h are combined can be stably drained by the water receiver 5 through the minute gap 3.

  Further, a drain hole 6 is formed on the vehicle outer side surface of the water receiver 5 so as to flow downward through the minute gap 3 and drain the water received by the water receiver 5 to the outside of the vehicle. In addition, the drain hole 6 is shown with the broken line in the figure. Thereby, after the water flowing downward through the minute gap 3 is received by the water receiver 5, the water reaching the bottom of the water receiver 5 can be discharged outside the vehicle through the drain hole 6.

  In addition, as shown to (a) of FIG. 1, the water receiver 5 has made the shape bent gently in the substantially L shape in the water drain hole 6 vicinity. Further, as shown in FIG. 4 (e), the water receiver 5 has a substantially elongated funnel shape having an opening at the top so that water flowing from above can be received. The drain hole 6 is formed as a hole penetrating the first inner wall 11 in the vicinity of the bottom of the water receiver 5 so that the water received by the water receiver 5 finally flows downward in the vehicle exterior. .

Details of the drainage structure from the drain hole 6 until it is finally discharged outside the vehicle will be described below.
<About drainage structure>
Next, based on FIG. 6, the drainage structure until the water that has flowed into the water receiver 5 through the minute gap 3 is finally discharged out of the vehicle from the drain hole 6 formed in the bottom of the water receiver 5. explain.

  As for the drainage structure until the water is finally discharged out of the vehicle from the drain hole 6, a structure in which a hole is made in the door panel as in the technique described in Patent Document 2 may be adopted. A drainage structure as shown in FIG. 6 can be illustrated as a structure without opening. FIG. 6A is a diagram showing a configuration of a drainage structure according to an embodiment of the present invention, and FIG. 6B is a cross-sectional view taken along the line F-F in the diagram shown in FIG. FIG.

  As shown in FIG. 6B, a drain recess 14 and a drain bead 15 are provided on the door panel mounting surface side of the hinge door 101 of the first inner wall 11 of the first seal member 1. The drain recess 14 is a recess facing the door panel mounting surface of the hinge door 101, and the door panel mounting surface and the first inner wall 11 are not elastically contacted in the vicinity of the location where the drain recess 14 is formed on the first inner wall 11. Here, a drainage space 16 (see drainage spaces 16-1 to 16-3 described later) is formed by a space surrounded by the drainage recess 14 and the door panel mounting surface.

  A drainage bead 15 that elastically contacts the door panel mounting surface is provided below the drainage recess 14 so that water does not ooze downward from the drainage recess 14.

  Moreover, as shown to (a) of FIG. 6, the drainage space 16 (The drainage spaces 16-1 to 16-3 are collectively called the drainage space 16) is provided under the drain hole 6. FIG. The drainage space 16 is provided so as to be inclined obliquely downward toward the rear of the vehicle (rear side; second seal member 2 side) as viewed from the vehicle exterior.

  With such a drainage structure, as shown in FIG. 6 (a), the water collected by the water receiver 5 provided on the inner side surface of the first inner wall 11 of the first seal member 1 6, water is led to the rear of the vehicle (rear side; second seal member 2 side) along the drainage space 16-1 on the mounting surface side of the first inner wall 11. Thereafter, the water is diverted to the outside of the vehicle by the drainage space 16-2 on the mounting surface side of the first curved wall 13. Next, the water is guided to the lower outside of the vehicle by the drainage space 16-3 on the mounting surface side of the second inner wall 12. Finally, the water is drained from the end point of the drainage space 16 on the mounting surface side of the second inner wall 12 on the vehicle outer side and in the vicinity of the lowermost side to the vehicle outer side. With such a drainage structure, the drainage structure can be set relatively easily without complicating the shape of the mounting surface side of the second seal member 2 in particular.

  Here, in the first seal member 1, the first curved wall 13 that elastically contacts the second curved wall 22 of the second seal member 2 is defined as the seal boundary portion, and the first inner wall 11 side is defined as “vehicle inside”, The second inner wall 12 side is defined as “vehicle outside”. The drainage structure below the drain hole 6 described above can be configured in the same manner as the drainage structure described in Patent Document 3.

[Outline of Seal Structure According to Embodiment 2]
Another embodiment of the present invention will be described below. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.

  As shown in FIG. 3A, in the seal structure according to the present embodiment, the first inner wall 11 is provided with a guide rib 11 a that guides water flowing downward through the minute gap 3 to the water receiver 5. This is different from the seal structure of the first embodiment. In FIG. 3A, the first seal member 1 is shown in a perspective view as seen from an obliquely upper rear side, and the second seal member 2 is shown in a front view as seen from the vehicle inner side.

  Further, the guide rib 11a of the present embodiment is inclined substantially linearly in a diagonally downward direction from the rear end to the front end. Thereby, the water flowing downward through the minute gap 3 can be reliably guided by the water receiver 5 through the guide rib 11a by appropriately setting the size and arrangement direction of the guide rib 11a.

  A part on the rear side of the guide rib 11a is indicated by a broken line, but this is because a part on the rear side of the guide rib 11a is present on the outer side of the tip protruding wall 2a (on the tip protruding wall 2a). Is covered). In other words, a part of the guide rib 11a on the rear side is in elastic contact with the vehicle outer surface of the tip protruding wall 2a. Thereby, the water flowing downward through the minute gap 3 can be reliably received by the guide rib 11a.

  In addition, as shown to (a) of FIG. 3, the water receptacle 5 provided in the 1st seal member 1 has made the shape bent gently in the substantially V shape in the water drain hole 6 vicinity. Here, the extension line L2 of the rear portion of the water receiver 5 provided on the first inner wall 11 of the first seal member 1 with respect to the drain hole 6 is inclined downward as it goes from the rear side to the front side. Yes.

  Further, the front end portion of the guide rib 11a is located below the rear end portion, and the guide rib 11a is also inclined obliquely downward as it goes from the rear side to the front side. That is, the extending direction of the guide rib 11a is inclined in the same direction as the inclination direction of the rear portion of the water receiver 5 from the drain hole 6 with respect to the horizontal direction.

  More specifically, as shown to (a) of FIG. 3, the extending | stretching line L1 of the guide rib 11a is from the drain hole 6 of the water receptacle 5 provided in the 1st seal member 1 with respect to the line L0 of a horizontal direction. Is also inclined in the same direction as the inclination direction of the extending line L2 of the rear portion. Further, in this embodiment, the shape θ is set so that the angle θ formed by the extending line L1 and the horizontal line L0 of the guide rib 11a is 15 degrees or more.

  Thereby, even if the front and rear of the entire vehicle are inclined due to parking of the vehicle itself on the inclined road surface, it is possible to suppress the water flowing downward through the minute gap 3 from flowing to the rear side.

  Next, (b) and (c) in FIG. 3 are before and after the second inner wall 12 and the second seal member 2 are elastically contacted, or before and after the second curved wall 22 and the first seal member 1 are elastically contacted, respectively. Shows the state. As shown in FIG. 3C, the second curved wall 22 and the second inner wall 12 are in elastic contact with each other, whereby the second curved wall 22 is elastically deformed, and the second curved wall 22 is in close contact with the second inner wall 12. . Thereby, the sealing performance between the 2nd curved wall 22 and the 2nd inner wall 12 is ensured.

  Further, as shown in FIG. 3C, when the first seal member 1 and the second seal member 2 are in elastic contact, a part of the rear side of the guide rib 11a is covered with the tip protruding wall 2a. It is in a state. Thereby, the water flowing downward through the minute gap 3 can be reliably received by the guide rib 11a.

  The water flowing downward through the minute gap 3 shown in FIG. 3A is guided from the rear side to the front side through the guide rib 11a. The water that has reached the front end of the guide rib 11a is received by the water receiver 5 disposed below the guide rib 11a. Thereby, the water flowing downward through the minute gap 3 can be guided to the water receiver 5 through the guide rib 11a.

  Next, (d) of FIG. 3 is a figure which shows an example of the cross section of a guide rib. The cross section of the guide rib 11a of this example has a substantially rectangular shape, and the corners of the substantially rectangular shape are smooth curved surfaces. The width W1 of the cross section of the guide rib 11a of this example is about 1 mm, and its height h1 is also about 1 mm. Further, the height of the guide rib 11a is gradually reduced from the front side toward the rear side at the end portion on the front side. Thereby, the water that has reached the front end portion of the guide rib 11 a can easily flow downward toward the water receiver 5.

  Next, (e) of FIG. 3 is a figure which shows another example of the cross section of a guide rib. The cross-section of the guide rib 11a 'in this example has a substantially triangular shape, and the top of the substantially triangular shape is a smooth curved surface. The width W2 of the cross section of the guide rib 11a 'of this example is about 1 mm, and its height h2 is also about 1 mm. Further, the height of the guide rib 11a 'is gradually reduced from the front side toward the rear side at the end portion on the front side. As a result, the water that has reached the front end of the guide rib 11 a ′ can easily flow downward toward the water receiver 5.

As shown in FIG. 4A, in the seal structure according to the present embodiment, the first inner wall 11 has a step 11b for suppressing water flowing downward through the minute gap 3 from flowing to the rear side. It differs from the seal structure of Embodiments 1 and 2 in that it is provided. In FIG. 4A, the first seal member 1 is shown in a perspective view seen from the rear side obliquely upward, and the second seal member 2 is shown in a front view seen from the vehicle interior side.

  The step 11 b is formed continuously from the rear end of the guide rib 11 a to one end of the water receiver 5. Further, the step 11b has a convex shape that protrudes inward from the first inner wall 11. Thereby, the water flowing downward through the minute gap 3 can be prevented from flowing to the rear side by the step 11b.

  The front end of the step 11b is located below the end on the rear side, and the step 11b is inclined substantially linearly in the diagonally downward direction from the rear side to the front side. Note that the inclination angle of the step 11b is steeper than the inclination angle of the guide rib 11a.

  A part on the rear side of the step 11b is indicated by a broken line, but this is because a part on the rear side of the step 11b exists on the vehicle exterior side of the tip protruding wall 2a (on the tip protruding wall 2a). Is covered). In other words, a part of the rear side of the step 11b is in elastic contact with the vehicle outer surface of the tip protruding wall 2a.

  Accordingly, the step 11b can reliably prevent the water flowing downward through the minute gap 3 from flowing to the rear side. FIGS. 4B and 4C show the states before and after the second inner wall 12 and the second seal member 2 are elastically contacted, respectively, or before and after the second curved wall 22 and the first seal member 1 are elastically contacted. Show. As shown in FIG. 4C, the second curved wall 22 and the second inner wall 12 are elastically contacted, whereby the second curved wall 22 is elastically deformed, and the second curved wall 22 is in close contact with the second inner wall 12. . Thereby, the sealing performance between the 2nd curved wall 22 and the 2nd inner wall 12 is ensured.

  Next, as shown in FIG. 4 (d), the lower end portion on the front side of the step 11b is connected to the front side of the base portion where the rear end portion of the water receiver 5 is connected to the first inner wall 11. Has been. FIG. 4D shows a front end portion of the step 11b. Thereby, the water which reached the edge part of the front side of the level | step difference 11b can be reliably received with the water receptacle 5. FIG.

  FIG. 4E is a perspective view showing the structure in the vicinity of the water receiver 5. As shown in (e) of FIG. 4, the water receiver 5 has a shape that is gently bent in an approximately L shape near the drain hole 6. Further, the water receiver 5 has a substantially elongated funnel shape having an opening in the upper part so that water flowing from above can be received. The drain hole 6 is formed in the vicinity of the bottom of the water receiver 5 as a hole that penetrates the first inner wall 11 so that the water received by the water receiver 5 finally flows downward in the vehicle exterior. .

  The front end of the step 11 b is smoothly connected to the corner of the opening of the water receiver 5 on the rear side of the vehicle. Thereby, the water that has reached the front end of the step 11 b can easily flow into the water receiver 5.

[Outline of Seal Structure According to Embodiment 4]
Next, as shown in FIG. 5, in the seal structure according to the present embodiment, in addition to the guide rib 11a and the step 11b described above, the guide rib 11c is disposed below the guide rib 11a. It differs from the 1-3 seal structure. In FIG. 5, the first seal member 1 is shown in a perspective view seen from the rear side obliquely upper side, and the second seal member 2 is shown in a front view seen from the vehicle interior side.

  The guide rib 11c of the present embodiment is inclined substantially linearly in a diagonally downward direction from the rear end to the front end. That is, the front end portion of the guide rib 11c is positioned below the rear end portion, and the guide rib 11c is inclined obliquely downward from the rear side toward the front side. Further, the guide rib 11c and the guide rib 11a are disposed substantially parallel to each other.

  The guide rib 11 c receives water leaked from the guide rib 11 a existing in the upper part to the vehicle inner side and guides the received water to the water receiver 5. For this reason, it can suppress more reliably that the water which oozed out from the part which each seal member of the hinge door 101 and the slide door 102 joins leaks to the vehicle inside.

  A part on the rear side of the guide rib 11c is indicated by a broken line. This is because a part on the rear side of the guide rib 11c is present on the vehicle exterior side of the tip protruding wall 2a (on the tip protruding wall 2a). Is covered). In other words, a part of the guide rib 11c on the rear side is in elastic contact with the vehicle outer surface of the tip protruding wall 2a. Thereby, the water leaked from the guide rib 11a to the vehicle inner side can be reliably received by the guide rib 11c.

  A plurality of guide ribs may be provided as in this embodiment. Regarding the guide ribs in a plurality of stages, the guide ribs present in the lower part receive the water that has been transmitted to the inside of the vehicle from the guide ribs present in the upper part and guide the received water to the water receiver 5. For this reason, it can suppress more reliably that the water which exuded from the part which each seal member of the hinge door 101, the slide door 102, and the body opening edge part 100h joins leaks into the vehicle inside.

[Additional Notes]
