  • the inner panel 14 is formed with one of the service holes 15 (hereinafter referred to as the "service hole 151") above the through hole 52 and the slit 22. Therefore, as shown by the dashed arrow in FIG. 2, it is required to prevent water falling downward from the service hole 151 from flowing between the inner panel 14 and the film 20 and entering the passenger compartment through the slit 22.
  • the vehicle door structure 1 of this embodiment has the following configuration to better prevent water from entering the vehicle interior through the slit 22.
  • the inner panel 14 has a regulator mounting portion 50 for mounting the manual regulator 40.
  • the regulator mounting portion 50 includes the through hole 52 and a reinforcing portion 54 formed around the through hole 52.
  • the reinforcing portion 54 extends in the vehicle front-rear direction across the through hole 52 and the slit 22, and protrudes from a base portion 14a on the passenger compartment side surface of the inner panel 14 toward the passenger compartment side.
  • the through hole 52 is formed at a tip 54a on the passenger compartment side of the reinforcing portion 54.
  • the tip 54a on the passenger compartment side of the reinforcing portion 54 is located closer to the passenger compartment than a seal mounting surface 142 described later.
  • the upper edge 54u of the reinforcing portion 54 includes an inclined surface 56 that extends downward as it moves away from the slit 22 in the vehicle longitudinal direction. More specifically, the upper edge 54u includes an arc-shaped portion 541u that extends in an arc around the through-hole 52, and an extension portion 542u that extends downward from the arc-shaped portion 541u toward the rear side in the vehicle longitudinal direction. As a result, the extension portion 542u extends from the upper end of the arc-shaped portion 541u to form the inclined surface 56.
  • the seal member 30 includes a seal extension 60.
  • the seal extension 60 extends in the vehicle front-rear direction from a position in the vicinity of the service hole 151 of the portion attached along the outer edge of the film 20.

  • the seal mounting surface 142 protrudes toward the vehicle cabin further than the base 14a. However, as described above, the seal mounting surface 142 is located closer to the outer panel 12 than the tip 54a of the reinforcement portion 54 on the vehicle cabin side. Because both the seal mounting surface 142 and the reinforcement portion 54 protrude from the base 14a toward the vehicle cabin, a recess 146 recessed toward the outer panel 12 is formed between the seal mounting surface 142 of the inner panel 14 and the upper edge 54u of the reinforcement portion 54.
  • the seal mounting surface 142 extends from in front of the service hole 151 to behind the through hole 52 and slit 22 of the regulator mounting portion 50 in the vehicle fore-and-aft direction. More specifically, the seal mounting surface 142 extends to the inclined surface 56 of the upper edge portion 54u of the reinforcement portion 54 (to the middle of the extension portion 542u). In this embodiment, the lower edge 151a of the service hole 151 extends while sloping downward in the vehicle fore-and-aft direction, and the seal mounting surface 142 along the lower edge 151a also extends while sloping downward in the vehicle fore-and-aft direction.
  • a positioning portion 144 is formed at the rear end of the seal mounting surface 142 in the vehicle front-rear direction.
  • the positioning portion 144 is formed to be continuous with a reinforcing portion 148 that protrudes from the base portion 14a of the inner panel 14 toward the passenger compartment, and protrudes further toward the passenger compartment than the seal mounting surface 142. It is preferable that the positioning portion 144 protrudes further toward the passenger compartment than the seal extension portion 60 attached to the seal mounting surface 142. Note that the positioning portion 144 and the film 20 are not in close contact with each other, and a gap is formed between them.
  • the seal extension portion 60 attached to the seal mounting surface 142 extends along the lower edge 151a of the service hole 151, and extends between the regulator mounting portion 50 and the service hole 151 so as to cover the upper part of the through hole 52 and the slit 22.
  • the seal extension portion 60 extends from the front side of the service hole 151 in the vehicle longitudinal direction. That is, the start end 62 (see FIG. 3) of the seal extension portion 60 is located forward of the service hole 151 in the vehicle longitudinal direction.
  • the end 64 (see FIG. 3) of the seal extension portion 60 is positioned by the positioning portion 144. That is, the seal extension portion 60 is attached to the seal mounting surface 142 so that its end 64 extends to the positioning portion 144.
  • the water that flows over the seal extension portion 60 flows downward from the end 64.
  • This water that flows downward from the end 64 flows between the inner panel 14 and the film 20.
  • the end 64 of the seal extension portion 60 is located rearward of the slit 22 in the vehicle front-rear direction, the water from the end 64 flows downward to a position away from the slit 22.
  • the end 64 of the seal extension portion 60 extends to the positioning portion 144 of the inner panel 14, most of the water that flows to the end 64 flows downward along the surface of the positioning portion 144. In other words, the water is prevented from flowing from the end 64 to the underside of the seal extension portion 60. Therefore, the end 64 and the positioning portion 144 do not necessarily need to abut each other, and a small gap may be formed between them to prevent the water that flows to the end 64 from flowing to the underside of the seal extension portion 60.
  • the water can be temporarily received by the upper edge 54u as described above, and the received water does not immediately flow into the slit 22.
  • the received water is guided in a direction away from the slit 22 along the arc-shaped portion 541u and the extension portion 542u.
  • the tip 54a on the passenger compartment side of the reinforcing portion 54 is located closer to the passenger compartment than the seal mounting surface 142, the received water is more effectively prevented from flowing into the slit 22.
  • water that flows into the passenger compartment side of the inner panel 14 from the service hole 151 is prevented from entering the passenger compartment side via the slit 22.
  • the vehicle door structure 1 comprises the door body 10 including the inner panel 14 covering the inside surface and the outer panel 12 forming the outside surface, the window glass 18 that can move up and down between the inner panel 14 and the outer panel 12, a waterproof film (waterproof film) 20 arranged on the passenger compartment side of the inner panel 14, a sealing member 30 that attaches the film 20 to the inner panel 14, and a manual regulator 40 that has a shaft (regulator shaft) 44 attached to a handle (regulator handle) 42 and passing through the inner panel 14 and the film 20, and raises and lowers the window glass 18 as the shaft 44 rotates.
  • the inner panel 14 has a regulator mounting portion 50 including a through hole 52 through which the shaft 44 is inserted, and a service hole 151 for work formed above the through hole 52, the film 20 has a slit (shaft insertion portion) 22 through which the shaft 44 is inserted at a position corresponding to the through hole 52, and the sealing member 30 has a seal extension portion 60 extending between the regulator mounting portion 50 and the service hole 151 so as to cover the through hole 52 and the upper part of the slit 22.
  • the seal extension 60 extending between the regulator mounting portion 50 and the service hole 151 blocks the water, preventing it from flowing down into the slit 22. Therefore, with the vehicle door structure 1 according to the embodiment, it is possible to more effectively prevent water from entering the passenger compartment from the position where the shaft 44 of the manual regulator 40 penetrates the film 20.
  • seal extension 60 extends while slanting downward in the vehicle's fore-and-aft direction. This configuration allows water on the seal extension 60 to be smoothly guided in the vehicle's fore-and-aft direction without accumulating.
  • the regulator mounting portion 50 also has a reinforcing portion 54 that protrudes from the inner panel 14 toward the passenger compartment, and the tip 54a on the passenger compartment side of the reinforcing portion 54 has a through hole 52 formed therein and is located closer to the passenger compartment than the seal mounting surface 142 to which the seal extension portion 60 of the inner panel 14 is attached.
  • the upper edge 54u of the reinforcing portion 54 includes an inclined surface 56 (arc-shaped portion 541u and extension portion 542u) that extends downward as it moves away from the slit 22 in the vehicle longitudinal direction. This configuration allows water on the upper edge 54u of the reinforcing portion 54 to be smoothly guided away from the slit 22 without stagnation.
  • the inner panel 14 also has a positioning portion 144 that protrudes toward the passenger compartment and positions the end 64 of the seal extension portion 60.
  • This configuration allows most of the water that has flowed to the end 64 of the seal extension portion 60 to flow downward along the surface of the positioning portion 144, making it possible to prevent the water from reaching the underside of the seal extension portion 60. As a result, it is possible to prevent water from flowing from the underside of the seal extension portion 60 down into the slit 22.
  • the seal extension portion 60 extends from a position in the vicinity of the service hole 151 of the portion of the seal member 30 attached along the outer edge of the film 20, but the seal extension portion 60 may not be connected to the portion of the seal member 30 attached along the outer edge of the film 20.
  • the seal extension portion 60 extends in the vehicle front-rear direction at least from the end portion 58 (the front end of the reinforcing portion 54) located below the service hole 151 of the regulator attachment portion 50 to a position beyond the slit 22.
  • the inclined surface 56 (arc-shaped portion 541u, extension portion 542u) of the seal extension portion 60 and the reinforcement portion 54 extends downward toward the rear side in the vehicle longitudinal direction.
  • the inclined surface 56 of the seal extension portion 60 and the reinforcement portion 54 may extend in different directions depending on the positions of the regulator mounting portion 50 and the service hole 151.
  • the inclined surface of the seal extension portion 60 and the reinforcement portion 54 may extend downward toward the front side in the vehicle longitudinal direction, for example.
  • the film 20 may be formed with a shaft insertion portion, such as a through hole, through which the shaft 44 can be inserted, rather than being limited to a slit 22.
