[0013] [Door body] The door body 2 includes a door outer panel, a door inner panel 21, a cover 3, and a bracket 4, all of which are not shown.
[0014] The door outer panel constitutes the exterior design surface of the door structure 1. The door inner panel 21 is disposed on the interior side of the door outer panel. A space is provided between the door outer panel and the door inner panel 21. A pressure sensor (not shown) is provided in this space. The pressure sensor detects pressure changes in the space. By detecting pressure changes in the space, a side collision is detected. The door inner panel 21 is provided with a service hole 22. The service hole 22 is a hole through which a worker can insert his or her hand into the space when assembling the vehicle door structure 1.
[0015] As shown in FIG. 2, the cover 3 covers the service hole 22. The cover 3 has a first region 31 corresponding to the service hole 22 and a second region 32 provided around the first region 31. The first region 31 overlaps the service hole 22 when the cover 3 is viewed from the side as shown in FIG. 2. That is, the first region 31 is a region that faces the service hole 22 without facing the vehicle interior surface of the door inner panel 21. The second region 32 is provided outside the service hole 22. The second region 32 faces the vehicle interior surface of the door inner panel 21. The second region 32 is fixed to the door inner panel 21 by the above-mentioned first fastening member 51, the plurality of third fastening members 53, and the plurality of resin clips 54. The outer peripheral edge portion of the second region 32 is sealed all around.
[0016] The bracket 4 reinforces the door inner panel 21. The bracket 4 in this embodiment is formed of a long and thin plate-like piece. The bracket 4 in this embodiment is provided so that the direction along the longitudinal direction of the bracket 4 is along the front and rear of the vehicle. Unlike this embodiment, the bracket 4 may be provided so that the direction along the longitudinal direction of the bracket 4 is along the up-down direction, or along a direction intersecting both the up-down direction and the front-rear direction. The bracket 4 is fixed to the door inner panel 21 so as to straddle the service hole 22 at a location overlapping the armrest 63 when the bracket 4 is viewed from the side as shown in FIG. 1.
[0017] As shown in FIG. 2, the bracket 4 has a first portion 41, a second portion 42, a third portion 43, and a fourth portion 44 in this order from the front to the rear. When the bracket 4 is viewed from the side as shown in FIG. 2, the first portion 41 overlaps the second region 32 of the cover 3 located forward of the service hole 22. The first portion 41 is fixed to the door inner panel 21 by a first fastening member 51. When the door structure 1 is viewed from the side as shown in FIG. 1, the first portion 41 overlaps the pull handle 62 as shown in FIGS. 3 and 4. When the bracket 4 is viewed from the side as shown in FIG. 2, the second portion 42 overlaps the first region 31 of the cover 3 as shown in FIG. 5. That is, when the bracket 4 is viewed from the side as shown in FIG. 2, the second portion 42 overlaps the service hole 22 as shown in FIG. 5. The third portion 43 overlaps the second region 32 of the cover 3 located rearward of the service hole 22 as shown in Fig. 6 when the bracket 4 is viewed from the side as shown in Fig. 2. The fourth portion 44 overlaps the door inner panel 21 exposed from the cover 3 when the bracket 4 is viewed from the side as shown in Fig. 2. The fourth portion 44 is fixed to the door inner panel 21 by a second fastening member 52.
[0018] As shown in Figures 3 to 6, the bracket 4 of this embodiment has a pressing portion 45 that presses the cover 3 toward the outside of the vehicle. The pressing portion 45 presses the cover 3 toward the outside of the vehicle, thereby improving the sealing performance of the service hole 22 by the cover 3. This improves the side collision detection performance of the pressure sensor described above. Furthermore, moisture is prevented from entering the vehicle interior through the service hole 22. Since there is no need to provide a member separate from the bracket 4 to improve sealing performance, the vehicle door structure 1 is not likely to be heavy or expensive and is excellent in productivity.
[0019] The pressing portion 45 of this embodiment is provided so as to protrude from the lower portion of the bracket 4 toward the vehicle exterior. The pressing portion 45 is configured to have a C-shaped cross section. The pressing portion 45 is provided in an area of the bracket 4 that overlaps with the cover 3 when the bracket 4 is viewed from the side as shown in FIG. 2. The pressing portion 45 of this embodiment is provided over the entire area of the first portion 41, the second portion 42, and the third portion 43 of the bracket 4, except for the fourth portion 44 of the bracket 4, when the bracket 4 is viewed from the side as shown in FIG. 2. The pressing portion 45 of this embodiment presses the second region 32 of the cover 3 located in front of the service hole 22 toward the vehicle exterior as shown in FIG. 3 and FIG. 4, presses the first region 31 of the cover 3 toward the vehicle exterior as shown in FIG. 5, and presses the second region 32 of the cover 3 located behind the service hole 22 toward the vehicle exterior as shown in FIG. 6. As shown in FIG. 6, the pressing portion 45 presses the outer peripheral edge of the cover 3 toward the vehicle exterior. Unlike this embodiment, the pressing portion 45 may be provided only in a region of the bracket 4 that overlaps with the first region 31 or the second region 32 of the cover 3. In that case, the pressing portion 45 presses only the first region 31 or the second region 32 of the cover 3 toward the outside of the vehicle.
[0020] The present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.
[0021] For example, the bracket may be attached to the door inner panel by a plastic clip instead of the first and second fastening members.
[0022] For example, the cover may have a pressing portion. This pressing portion is provided so that a part of the cover protrudes toward the inside of the vehicle. If the bracket is attached so as to be pressed against the pressing portion of the cover, the cover is pressed toward the inside of the vehicle by the reaction force of the pressing portion pressing against the bracket.
