Description

[Technical Field]

[0001] The present invention relates to a vehicle door. [Background technology]

[0002] Conventionally, vehicle doors are mainly known to be configured with a door panel made of a metal outer panel and inner panel that form the exterior surface of the door, and a resin trim that forms the interior surface of the door. On the other hand, as disclosed in Patent Document 1 below, for example, a configuration is also known in which the inner panel is made of synthetic resin, and various functional parts are attached to the inner panel before it is assembled to the outer panel, with the aim of reducing the number of assembly steps and reducing manufacturing costs. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-318532 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional vehicle doors, such as the vehicle door described in Patent Document 1, are generally configured with three plate-like members stacked in the interior-exterior direction of the vehicle. Because conventional vehicle doors require a large number of parts, which increases the manufacturing process and manufacturing costs, recent studies have focused on vehicle doors configured with two plate-like members. However, such a configuration requires the provision of a waterproof structure (sealing structure) on the panel that constitutes the interior design surface, as opposed to the waterproof structure (sealing structure) provided between the outer panel and inner panel or between the inner panel and service hole cover in the vehicle door described in Patent Document 1. Specifically, a sealing structure must be provided between two or more members that constitute the interior panel.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a seal in a panel that constitutes the interior design surface of a vehicle door. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle door disclosed in the present application has the following structure. (1) A first panel that constitutes the exterior design surface; a second panel attached to the interior side of the first panel so as to face the interior side and constitute a design surface on the interior side; The second panel is made up of two or more panel members each having a design surface portion that forms the interior design surface, and is configured such that a portion of a second panel member, which is another of the panel members, overlaps from the interior side with a peripheral portion that is a portion formed outside the design surface portion of a first panel member, which is one of the panel members; The first panel member is made of die-cast aluminum and has a first panel member-side rib extending upright toward the interior of the vehicle on the peripheral edge thereof. The second panel member has a second panel member side rib that stands toward the outside of the room, A vehicle door, characterized in that a sealant is interposed between the first panel member side rib and the second panel member side rib.

[0007] The vehicle door disclosed in the present application is based on a vehicle door generally composed of two panels, a first panel and a second panel. The second panel, which constitutes the interior design surface, is constructed by assembling two or more panel members, each of which has a portion of the interior design surface. A vehicle door with such a configuration requires a sealing structure between the two or more panel members. The vehicle door disclosed in the present application has a novel design in which the exterior first panel member is made of metal. Because the first panel member is die-cast aluminum, which allows for a relatively high degree of molding flexibility, ribs can be molded on the surface. The ribs on the first panel member can be used to firmly sandwich a sealing material between the ribs on the second panel member and the first panel member. Therefore, the vehicle door disclosed in the present application ensures sufficient sealing performance in the second panel member, which constitutes the interior design surface.

[0008] The vehicle door having the above-described structure can be configured in the following various ways.

[0009] (2) One of the first panel member side rib and the second panel member side rib is formed as a pair extending parallel to each other with a gap therebetween, the other of the first panel member side rib and the second panel member side rib is a single rib, The vehicle door described in item (1), wherein, when the first panel member and the second panel member are assembled, the tip of the other panel member is inserted between the pair of the first panel member and the pair of the first panel member, and the sealing material is sandwiched between the other panel member and the pair of the first panel member.

[0010] In a vehicle door with this configuration, the alternating ribs can firmly hold the sealant. Alternatively, by providing the sealant between a pair of ribs, the sealant does not shift and the other rib can be firmly abutted against the sealant. Furthermore, if the sealant is held between the pair of ribs in an elastically deformed state, there is no need to attach the sealant, which reduces costs and the number of work steps.

[0011] (3) The first panel member has a step portion between the first panel member side rib and the design surface portion, the step portion being offset from the design surface portion toward the exterior side of the room, The second panel member has a standing wall portion that stands from the outer edge of the design surface portion toward the outside of the room, The vehicle door according to item (1) or (2), wherein a second sealant is interposed between the step portion and the tip of the standing wall portion.

[0012] The vehicle door disclosed in the present application has a second seal disposed parallel to the first seal disposed between the ribs on the boundary side between the first and second panel members, thereby improving sealing performance. This configuration can be used for the entire boundary between the first and second panel members, or can be used only in certain locations where high sealing performance is required. [Effects of the Invention]

[0013] According to the present invention, sealing can be performed on a panel that constitutes the interior design surface of a vehicle door. [Brief explanation of the drawings]

[0015] <Overall structure of the side door> The vehicle door according to the embodiment of the present invention is a front side door of an automobile (vehicle) as a vehicle. The overall configuration of the side door 10 according to the present embodiment will be described with reference to Fig. 1 to Fig. 3. In each drawing, the directions indicated by the arrows are FR (front of the vehicle), RR (rear of the vehicle), IN (inside the vehicle), and OUT (outside the vehicle).

[0016] As shown in FIG. 1 , the side door 10 of this embodiment is provided with a door pocket 11 and an armrest 12 as an elbow rest for a passenger on its interior side. Although not shown, the armrest 12 is also provided with an inside handle for opening and closing the side door 10, a pull handle that the passenger can place their hand on (grasp) to open or close the side door 10, and a switch base equipped with operation switches for opening and closing the window and locking and unlocking the side door 10. The side door 10 is also provided with a side mirror 16 on its exterior side. The side door 10 is also provided with a window device 17 that can be raised and lowered, and a locking device 18 that locks and unlocks the side door 10 relative to the vehicle body. The side door 10 of this embodiment is attached to the vehicle body at its front end via a hinge mechanism 19, allowing the side door 10 to swing open and close.

[0017] As shown in Fig. 2, the side door 10 is configured by assembling two panels, a first panel 20 and a second panel 22. The first panel 20 is the outermost panel of the automobile that constitutes the exterior of the automobile and is made of steel plate. The second panel 22 also serves as an interior member, that is, a panel that has a portion that constitutes the interior appearance (interior design surface) of the automobile. The side door 10 is configured such that the first panel 20 and the second panel 22 face each other, with no other panels interposed between them.

[0018] In this embodiment, the first panel 20 is made of a steel plate, but it may be made of other metals or resin. Examples of resins that can be used for the first panel 20 include fiber-reinforced resins (thermosetting resins such as unsaturated polyester, epoxy resin, polyamide resin, phenolic resin, etc., blended with glass fiber, carbon fiber, aramid fiber, polyethylene fiber, etc.), as well as polyacetal resin, polyamide resin, polycarbonate resin, polyimide resin, and ultra-high molecular weight polyolefin (polyethylene) resin. As will be described in detail later, most of the components of the side door 10 are attached to the second panel 22, and no components of the side door 10 are attached to the first panel 20.

[0019] As shown in Fig. 3, the second panel 22 is broadly composed of two panel members 24, 26. The panel member 24 is generally frame-shaped and includes the portion near the outer periphery of the second panel 22, and functions as a base member (hereinafter, may be referred to as "base member 24") to which the other panel member 26 is attached and various functional parts are attached. In this embodiment, the panel member 26 is made of resin, while the base member 24 is made of aluminum alloy and is aluminum die-cast. Note that examples of resins used for the second panel 22 (panel members 24, 26) include, in addition to polypropylene resin, polyethylene resin, polystyrene resin, polyester resin, and resins obtained by blending these resins with natural fibers.

[0020] The base member 24 also includes a main body 30 whose plate surface faces the interior and exterior of the vehicle, and protruding portions 32 that protrude from the front, bottom, and rear ends of the main body 30. The main body 30 has an opening 30a, giving it a generally rectangular frame shape. However, as shown in FIGS. 1 to 3, the front portion 30b of the main body 30 is exposed to the interior and forms the interior design surface. On the other hand, this front portion 30b is not overlapped by any other panel member on the exterior side of the vehicle and directly faces the first panel 20.

[0021] The front protruding portion 32a of the base member 24, which is a portion of the protruding portion 32 that protrudes forward from the front end of the main body 30, is attached to the vehicle body via the hinge mechanism 19. The hinge mechanism 19 requires increased assembly strength because forces related to opening and closing the door are concentrated therein. In this embodiment, the base member 24 is a member having an interior design surface, but is made of die-cast aluminum, so the side door 10 is firmly supported by the hinge mechanism 19. As described above, the side door 10 of this embodiment is configured such that, of the first panel 20 and the second panel 22, only the second panel 22 is attached to the vehicle body via the hinge mechanism 19. As described above, the base member 24 is die-cast aluminum, which makes it easier to ensure rigidity compared to a resin-made base member. Furthermore, because the base member 24 is die-cast aluminum, its thickness can be easily varied from position to position, thereby easily varying its rigidity from position to position. Therefore, the front protruding portion 32a is thicker than the main body portion 30, thereby increasing the rigidity.

[0022] The base member 24 also has an upward extension 34 extending upward on the front side. This upward extension 34 is a mounting seat for attaching the side mirror 16, and the side mirror 16 is fixed by a fastener while extending outward from the vehicle. A cover member 35 is attached to the interior side of the upward extension 34 to hide the fastener. In other words, the side mirror 16 is attached to the second panel 22.

[0023] As described above, the panel member 26 is made of resin and is attached to the interior side of the base member 24 so as to cover the opening 30a of the base member 24. In other words, almost the entire panel member 26 constitutes the interior design surface. This panel member 26 does not cover the entire interior side of the door panel like the door trim of a conventional side door, but is similar to that door trim and will be referred to as the trim member 26 in the following description. As shown in FIG. 2 , an armrest member 36 that forms the armrest 12 is attached to the trim member 26, and a pocket board member 37 that forms part of the inner surface of the door pocket 11 is also attached to the trim member 26. The peripheral edge of the trim member 26 overlaps the interior side of the base member 24 (the opening edge 30c of the opening 30a), but the majority of the trim member 26 directly faces the first panel 20 without being overlapped by any other panel member on the exterior side. Incidentally, the pocket board member 37 together with the trim member 26 can be regarded as one panel member, or it can be regarded as another panel member, and the second panel 22 can be regarded as being made up of three panel members.

[0024] The second panel 22 is provided on its exterior side with three longitudinal reinforcing members 40, 41, and 42 extending in the front-to-rear direction. Specifically, the three reinforcing members 40, 41, and 42 are disposed on the exterior side of the base member 24, spanning the front overhang 32a and rear overhang 32b of the base member 24. The first reinforcing member 40 extends parallel to the upper edge of the main body 30 of the base member 24. The second reinforcing member 41 is disposed below the first reinforcing member 40, along the inner surface of the first panel 20 near the center in the vertical direction (the portion that protrudes most toward the exterior). The third reinforcing member 42 functions as an impact beam to absorb impact from the exterior side during a vehicle side collision, and is disposed at approximately the height of the waist of an occupant seated inside the vehicle.

[0025] A window device 17 is disposed on the exterior side of the second panel 22, on the interior side of the three reinforcing members 40, 41, and 42. The window device 17 includes a plate-shaped window glass 44 and a regulator 45, which is a drive source for raising and lowering the window glass 44. To enable the window glass 44 to be raised and lowered, weather strips (not shown) are provided on the exterior side of the upper edge of the base member 24 and on the upper edge of the first reinforcing member 40 to fill the gap between the window glass 44 and allow the window glass 44 to be raised and lowered. The window glass 44 is slidably interposed between these opposing weather strips. Also, a wiring 46 connecting the regulator 45 to the switch base and a wiring 47 connecting the locking device 18 to the inside handle, as shown in FIG. 3, are held by the second panel 22.

[0026] The first panel 20 is detachably attached to the second panel 22, covering the second panel 22 from the outside, to which various functional components are attached. Specifically, as shown in FIG. 2, a plurality of clip seats 50 are provided at intervals around the periphery of the first panel 20, and the first panel 20 can be fitted to the second panel 22 using a plurality of clips attached to the clip seats 50. Fastening portions 52 are provided at two locations, at the front upper end and the rear upper end of the side door 10, so that the first panel 20 and the second panel 22 can be fastened with bolts from the passenger compartment side of the second panel 22. Specifically, as shown in FIG. 3, the first panel 20 has a female thread portion 52a with a female thread formed therein. The second panel 22, more specifically, has insertion holes 52b for inserting bolts at positions corresponding to the female thread portions 52a at the upper end of the front overhang portion 32a and the upper end of the rear overhang portion 32b of the base member 24, as shown in FIG. 1.

[0027] The first panel 20 does not have any functional parts of the side door 10 attached thereto, and is configured to be easily detachable from the second panel 22, to which various functional parts are attached. On the other hand, due to the presence of the fastening portion 52, when the side door 10 is locked to the vehicle body, the first panel 20 cannot be detached from the second panel 22 even if multiple clips are released from outside the vehicle compartment, and theft of the first panel 20 can be prevented.

[0028] As described above, in the side door 10 of this embodiment, the second panel 22 is composed of two panel members 24, 26. These panel members 24, 26 constitute the interior design surface (design surface portion) and have a portion that directly faces the first panel 20 without any other panel member overlapping the first panel 20. Therefore, in the side door 10 of this embodiment, many of the portions that form the interior design surface can be configured as a two-layer structure (double structure) of the first panel 20 and the second panel 22, thereby reducing the number of parts required for the entire side door 10. Furthermore, as shown in FIG. 2 , the side door 10 of this embodiment does not have any plate-like members between the first panel 20 and the second panel 22, ensuring a relatively large space and allowing for greater flexibility in the installation of functional components. Therefore, the side door 10 of this embodiment achieves simplified and easy manufacturing processes and reduced manufacturing costs.

[0029] <Second panel seal structure> The side door 10 of this embodiment configured as described above does not have a triple structure extending from the interior to the exterior of the vehicle cabin like conventional side doors, and the second panel 22 that forms the interior design surface is made up of two panel members 24, 26, each of which has an interior design surface, so a seal structure is required between the two panel members 24, 26 to prevent water from entering the cabin and to make the inside of the side door 10 an airtight space (to activate an air pressure sensor used to deploy an airbag). The side door 10 of this embodiment is characterized by its seal structure, and the seal structure between the base member 24 and the trim member 26 will be described in detail below with reference to Figures 4 to 7.

[0030] The base member 24 has a front portion 30b of the main body 30 as a design surface portion that forms the interior-facing design surface. Hereinafter, the front portion 30b may be referred to as the base-side design surface portion 30b. As shown in FIG. 3 , the base member 24 has an opening 30a and an opening edge (corresponding to a peripheral edge portion) 30c formed on the outer side (rear side) of the base-side design surface portion 30b. The trim member 26 is attached so as to overlap the opening edge 30c on the interior side, thereby closing the opening 30a. The sealing structure is provided at the portion where the opening edge 30c of the base member 24 and the trim member 26 overlap. In other words, the base member 24 corresponds to the first panel member, and the trim member 26 corresponds to the second panel member.

[0031] First, the seal structure 60 at the lower end side of the trim member 26 will be described with reference to Figure 4. The trim member 26 has a trim-side design surface portion 62 facing the interior side, and a lower standing wall portion 63 standing from the lower end of the trim-side design surface portion 62 toward the exterior side. The thickness of the lower standing wall portion 63 increases toward the tip (the end portion on the exterior side).

[0032] Meanwhile, the base member 24 has a base-side design surface portion 30d facing the interior side between the lower protrusion 32c and the opening edge 30c, and the upper side of the base-side design surface portion 30d is covered by the trim member 26. The base member 24 has a groove 64 formed along the edge (lower edge) of the opening edge 30c on the side of the base-side design surface portion 30d. In other words, the bottom surface portion 64a of the groove 64 corresponds to a stepped surface portion offset from the base-side design surface portion 30d toward the exterior side of the room, and the wall surface portion 64b of the groove 64 on the side of the base-side design surface portion 30d corresponds to a connecting portion connecting the base-side design surface portion 30d and the bottom surface portion (stepped surface portion) 64a.

[0033] A sealant 66 is provided on the bottom surface 64a of the groove 64. More specifically, the sealant 66 is, for example, made of rubber and has a longitudinal (tape-like) shape, and is attached along the connection between the bottom surface 64a and a wall surface 64c of the groove 64 opposite to the wall surface 64b. When attached, the sealant 66 is spaced apart from the wall surface 64b. The distance between the sealant 66 and the wall surface 64b is smaller than the thickness of the tip of the lower standing wall 63.

[0034] When the trim member 26 is assembled to the base member 24, the lower upright wall portion 63 enters the groove 64 and abuts against the lower wall surface portion 64b of the groove 64, crushing the sealing material 66. Therefore, in this seal structure 60, the sealing material 66 is provided inside the groove 64, making it difficult for occupants to see. Furthermore, because the sealing material 66 can be attached along the bottom surface portion 64a (or the wall surface portion 64c) of the groove 64, it can be easily positioned in an appropriate position, improving workability during manufacturing. Furthermore, because the sealing material 66 can be appropriately positioned at a position spaced from the lower wall surface portion 64b, it is possible to prevent the sealing material 66 from spilling out below the lower upright wall portion 63, and the sealing material 66 is not visible to occupants.

[0035] As explained above, the base member 24 is made of die-cast aluminum, which allows for a high degree of freedom in molding, making it possible to easily mold grooves 64 of the above-mentioned shape, which cannot be formed by press-molding steel plate.

[0036] Next, the seal structure 70 at the upper end side of the trim member 26 will be described with reference to Figure 5. The trim member 26 has a trim-side design surface portion 62 facing the interior side of the vehicle, and an upper standing wall portion 72 that stands from the upper end of the trim-side design surface portion 62 toward the exterior side of the vehicle. The thickness of the upper standing wall portion 72 increases toward its tip (the end portion on the exterior side). Furthermore, the trim member 26 has a rib 73 that protrudes from the back surface (the exterior side surface) and stands on the back side of the upper standing wall portion 72. This rib 73 is formed to extend parallel to the upper standing wall portion 72.

[0037] On the other hand, the base member 24 has a stepped shape in which the opening edge 30c is offset toward the exterior side relative to the base-side design surface portion (front portion) 30b. That is, the base member 24 has a stepped portion 76 formed on the opening edge 30c, which is composed of a stepped surface portion 74 and a connecting portion 75. A sealing material 77 is attached to the stepped surface portion 74.

[0038] In this seal structure 70, the trim member 26 compresses the seal material 77 not only with the upper upright wall portion 72 but also with the rib 73, and therefore, a tighter seal can be achieved compared to the seal structure 60.

[0039] 2, a pocket board member 37 is disposed above the seal structure 60, and a seal structure 80 is also provided between the pocket board member 37 and the base member 24. In this seal structure 80, a pair of base-side ribs 82 extending upright toward the interior of the vehicle are formed on the opening edge 30c of the base member 24, and a board-side rib 83 extending upright toward the exterior of the vehicle is formed on the lower end of the pocket board member 37. The board-side ribs 83 are intended to maintain the distance between the pocket board member 37 and the base member 24 in the interior / exterior direction of the vehicle, and thus the distance between the trim member 26 and the base member 24. The tip of the board-side rib 83 is located midway (midway in the up-down direction) between the pair of base-side ribs 82. In other words, the board-side rib 83 and the pair of base-side ribs 82 are arranged alternately in the up-down direction. Furthermore, the board-side rib 83 and the pair of base-side ribs 82 are sized to have a length (dimension in the interior / exterior direction of the vehicle) such that when the trim member 26 to which the pocket board member 37 is attached is attached to the base member 24, the tip of the board-side rib 83 fits between the pair of base-side ribs 82. A sealing material 84 is interposed between the board-side rib (second panel member-side rib) 83 and the pair of base-side ribs (first panel member-side ribs) 82 so as to be sandwiched therebetween.

[0040] Because the base member 24 is made of die-cast aluminum, it has a high degree of freedom in molding, and it is possible to easily mold the above-mentioned ribs 82, which cannot be formed by press-molding steel plate, thereby realizing a sealing structure 80 that can provide a tight seal between the base member 24 and the trim member 26 (pocket board member 37).

[0041] Next, the seal structure 90 at the rear end of the trim member 26 will be described with reference to Figure 7. The trim member 26 has a trim-side decorative surface portion 62 facing the interior side, and a rear upright wall portion 92 that stands from the rear end of the trim-side decorative surface portion 62 toward the exterior side. The thickness of the rear upright wall portion 92 increases toward its tip (the exterior end portion). The trim member 26 also has a generally box-shaped clip seat 93 on its exterior side. A clip 94 for attaching the trim member 26 to the base member 24 is attached to this clip seat 93.

[0042] On the other hand, the base member 24 has a stepped shape in which the opening edge 30c is offset toward the exterior side relative to the rear overhang 32b. That is, the base member 24 has a stepped portion 97 formed at the opening edge 30c, the stepped portion 97 consisting of a stepped surface portion 95 and a connecting portion 96. Furthermore, the stepped surface portion 95 has a mounting seat (flat portion) 98 formed therein, the mounting seat 98 having a through-hole (mounting portion) 98a into which the clip 94 is inserted, and the mounting seat 98 bulges outward from the stepped surface portion 95 toward the interior side. The base member 24 has a groove 99 formed by the stepped portion 97 and the mounting seat 98, and a sealing material 100 is attached in this groove 99.

[0043] With this configuration, the seal structure 90 has the mounting portions of the base member 24 and the trim member 26 located near the sealing portion, so that the seal material 100 can be firmly crushed, improving the sealing performance.

[0044] As disclosed in the above-described seal structure 80, the side door 10 of this embodiment includes a base member 24 (first panel member) made of die-cast aluminum and having a base-side rib 82, which is a first panel member-side rib, extending toward the interior of the vehicle at the peripheral edge 30c of the opening. The pocket board member 37 (second panel member) has a board-side rib 83, which is a second panel member-side rib, extending toward the exterior of the vehicle. A sealant 84 is interposed between the base-side rib 82 and the board-side rib 83. Because the base member 24 is made of die-cast aluminum, which allows for a relatively high degree of molding flexibility, the rib 82 can be molded on the surface. The base-side rib 82 can be used to firmly sandwich the sealant 84 between the base-side rib 82 and the rib 83 of the pocket board member 37. Therefore, the side door 10 of this embodiment ensures sufficient sealing performance in the second panel 22, which constitutes the interior design surface.

[0045] <Variation 1> In the side door 10, rainwater and the like easily penetrate through the window glass 44, and a particularly strong waterproof structure is required in the portion along the upper edge of the trim member 26. Therefore, a seal structure 110 shown in Figure 8 can be used instead of the seal structure 70. The seal structure 110 of this modified example is a structure that combines the seal structure 60 and the seal structure 80.

[0046] The trim member 112 has a trim-side design surface portion 114 facing the interior side of the vehicle, and a standing wall portion 115 that stands from the upper end of the trim-side design surface portion 114 toward the exterior side of the vehicle. The trim member 112 also has a rib 116 that protrudes from the rear surface (exterior side surface) and stands on the back side of the standing wall portion 115. The trim-side rib 116 is located lower than the rib 73 shown in FIG. 5. In other words, the distance between the trim-side rib 116 and the standing wall portion 115 is larger.

[0047] On the other hand, as in the above embodiment, the base member 120 has an opening edge 121 that is stepped and offset toward the exterior relative to the base-side design surface 122, and a step portion 125 consisting of a stepped surface portion 123 and a connecting portion 124 is formed on the opening edge 121. The base member 120 also has a pair of base-side ribs 126, 127 that stand upright from the stepped surface portion 123 toward the interior of the vehicle. A sealant (corresponding to a second sealant) 128 is attached between the connecting portion 124 and the upper base-side rib 126, and is configured to be crushed by the standing wall portion 115. Furthermore, the tip of the trim-side rib 116 is located midway (midway in the up-down direction) between the pair of base-side ribs 126, 127. As a result, the trim-side rib 116 and the pair of base-side ribs 126, 127 are configured so that, when the trim member 112 is attached to the base member 120, the tip of the trim-side rib 116 fits between the pair of base-side ribs 126, 127. A sealant 129 is interposed between the trim-side rib (second panel member-side rib) 116 and the pair of base-side ribs (first panel member-side ribs) 126, 127.

[0048] <Variation 2-1> In the above-described seal structures 80, 110, the seal material 84, 129 is sandwiched between three ribs, but is not limited to this. As shown in Fig. 9, the seal material 132 may be disposed between a pair of first panel member ribs 131 formed on a first panel member 130, which is made of die-cast aluminum, and may be crushed by the tip of a second panel member rib 135 formed on a second panel member 134. This modified seal structure prevents the seal material 132 from shifting, and allows the second panel member rib 135 to reliably abut against the seal material 132.

[0049] This sealing material 132 may be made of, for example, a flexible material and held between the pair of first panel member ribs 131 in an elastically deformed state. Also, for example, the sealing material 132 may be configured to be molded integrally with the first panel member 130 using two-color molding, or may be configured to be molded using a coating mold. In other words, this sealing structure does not require the sealing material 132 to be attached to the first panel member 130 or the second panel member 134, which can reduce costs and the number of work processes.

[0050] <Variation 2-2> Furthermore, in the above-described seal structures 80, 110 and the seal structure described above, a pair of first panel member ribs 131 are formed on the first panel member 130, which is aluminum die-cast, and a single second panel member rib 135 is formed on the second panel member 134, but it is also possible to use the configuration shown in Fig. 10. That is, a single first panel member rib 141 may be formed on the first panel member 140, which is aluminum die-cast, and a pair of second panel member ribs 143 may be formed on the second panel member 142, with a seal material 144 disposed between the pair of second panel member ribs 143, and the tips of the first panel member ribs 141 may crush the seal material 144.

[0051] <Variation 3> In the above-described embodiment and modified examples, the height of the trim-side rib provided on the trim member increases the risk of poor appearance due to sink marks on the trim-side design surface. Therefore, a seal structure 150 as shown in FIG. 11 may be used. In the seal structure 150, the base member 152 has a stepped opening edge 153 offset toward the exterior side relative to the base-side design surface 154. The opening edge 153 is formed with a pedestal portion 155 that protrudes toward the interior side, and a pair of base-side ribs 156, 157 are formed on the pedestal portion 155 and extend toward the interior side. With this configuration, the presence of the pedestal portion 155 reduces the distance between the base-side ribs 156, 157 and the rear surface of the trim member 160, allowing the height of the trim-side rib 161 on the trim member 160 to be reduced. Therefore, this seal structure 150 can prevent sink marks from occurring on the design surface portion 162 of the trim member 160. Incidentally, a groove 158 that is recessed when viewed from the inside of the vehicle is formed between the pedestal portion 155 and the base-side design surface portion 154, and the vertical wall portion 163 of the trim member 160 is adapted to be inserted into this groove 158.

[0052] <Other embodiments> The present invention is not limited to the above-described embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. For example, the following embodiments are also included within the technical scope of the present invention.

[0053] In the above embodiment, the second panel 22 includes two panel members each having a design surface portion, but it may include three or more panel members. The shapes of the panel members are not particularly limited, and various shapes can be adopted.

[0054] In the above embodiment, an automobile is used as an example of a vehicle, but the vehicle door of the present invention is not limited to this and can also be applied to other vehicles such as trains and recreational vehicles as ground vehicles, airplanes and helicopters as flying vehicles, and ships and submarines as marine and underwater vehicles.
