The door main body 14 includes a door outer panel 20 constituting an outer plate of the front side door 12, a door inner panel 22 (door inner member) constituting an inner plate of the front side door 12, and a door trim as an interior material (not shown). .

  The door outer panel 20 and the door inner panel 22 are disposed along the vehicle front-rear direction and the vehicle vertical direction, and are opposed to each other in the vehicle width direction. Thereby, in the space formed between the door outer panel 20 and the door inner panel 22, together with the window glass 18, although not shown, devices such as a door window regulator and a speaker for raising and lowering the window glass 18 are accommodated. The A harness connected to each device is routed in a space formed between the door outer panel 20 and the door inner panel 22. Further, between the upper ends of the door outer panel 20 and the door inner panel 22, an accommodation port (not shown) for accommodating the window glass 18 is formed.

  As shown in FIG. 1, a service hole 24 is formed in the door inner panel 22 for the purpose of assembling and maintaining a door window regulator or the like. The entire service hole 24 is covered by a service hole cover 30 from the inside (vehicle compartment side).

  The service hole cover 30 is made of resin and is disposed inside the door inner panel 22. The service hole cover 30 includes a cover main body 32 in which the service hole 24 is formed, and a rib portion 34 formed in accordance with the shape of the opening edge of the service hole 24 in a side view.

  The cover main body 32 is attached to the door inner panel 22 via a seal member 40 provided at the boundary with the door inner panel 22. The seal member 40 is formed in an annular shape and is disposed along the peripheral edge of the cover main body 32. The sealing member 40 is made of a known sealing material such as butyl rubber (isobutylene-isoprene rubber). The seal member 40 closes the gap at the boundary between the cover body 32 and the door inner panel 22.

  In the present embodiment, as shown in FIG. 1, an annular rib portion 34 is provided on the outer main surface of the cover main body 32 in a side view. As shown in FIG. 2, the rib portion 34 protrudes outward from the main surface on the outer side of the cover body 32 toward the door outer panel 20 and extends outward from the lower end edge 24 b of the service hole 24, and protrudes outward. It has an L-shaped shape bent downward at the tip. Hereinafter, as shown in FIG. 2, a portion of the rib portion 34 that extends outward from the base portion connected to the cover body 32 and covers the lower end edge 24b of the service hole 24 from above is referred to as a “rib portion body 36”. A portion extending downward from the outer end portion of the rib body 36 is referred to as a “bending portion 38”. In the present embodiment, a rib structure including the rib main body 36 and the bent portion 38 shown in FIG. 2 is provided on the lower side of the annularly formed rib portion 34 that faces the lower end edge 24b of the service hole 24. Yes.

  The length of the rib portion 34 in the vehicle width direction (the length of the rib portion main body 36 in the vehicle width direction) is such that the tip extending outward from the cover main body 32 exceeds the opening surface 24a of the service hole 24 in plan view. The length is not particularly limited as long as it is located outside the lower end edge 24b of the service hole 24. Further, the length of the rib portion 34 in the vehicle width direction is set so as not to contact the window glass 18 accommodated between the door outer panel 20 and the door inner panel 22. The length of the rib portion 34 in the vehicle width direction may be, for example, about 20 mm or more and 30 mm or less.

  The bent portion 38 is provided in the front-rear direction at the lower side portion of the rib portion 34 facing the lower end edge 24 b of the service hole 24. The rib portion 34 includes a rib portion main body 36 disposed so as to cover the upper end of the lower end edge 24b of the service hole 24, and a bent portion 38 extending downward from the distal end portion of the rib portion main body 36. As indicated by arrows A to C, rainwater or the like that falls on the outer main surface of the cover body 32 travels on the upper surface of the rib body 36 and then travels on the outer side of the bent portion 38 and from the lower end of the bent portion 38. Fall down. The length of the bent portion 38 is not particularly limited as long as water droplets transmitted to the lower end of the bent portion 38 protrude downward such that they do not move to the lower surface of the rib portion main body 36. The length of the bent portion 38 in the vertical direction may be, for example, about 5 mm to 10 mm.

  In the present embodiment, as shown in FIGS. 1 and 2, the rib portion 34 that covers the upper portion of the boundary between the service hole cover 30 and the door inner panel 22 is spaced upward from the lower edge 24 b of the service hole 24. is doing. As described above, by providing the rib portion 34 at a position spaced upward from the lower end edge 24b, the contact between the rib portion 34 and the door inner panel 22 when the service hole cover 30 is assembled is avoided, and the assembling property is improved. . The service hole 24 straddles the lower end edge 24b of the service hole 24 when the harness routed between the door outer panel 20 and the door inner panel 22 is pulled out to the inner side of the door inner panel 22 (door trim side). There are times when the harness is routed. In the present embodiment, since the rib portion 34 is spaced upward from the lower end edge 24 b of the service hole 24, the through hole through which the harness straddling the lower end edge 24 b of the service hole 24 passes is formed more than the rib portion 34 of the cover body 32. It can be provided below. In addition, when the rib part 34 and the lower end edge 24b of the service hole 24 are separated too much, when a water drop falls from the lower end of the bent part 38, there is a possibility of flying to the seal member 40 side due to vibration or the like. As shown, the rib portion 34 is preferably provided at the lower portion of the cover body 32.

  The operation of the above configuration will be described in detail below. As described above, in the vehicle door portion structure 10 according to the present embodiment, the service hole cover 30 projects from the inner side of the service hole 24 of the door inner panel 22 to the door outer panel 20 side. And a rib portion 34 extending to the outside of the lower end edge 24b of the service hole 24. The rib portion 34 includes a rib portion main body 36 that extends outward from a base portion that is connected to the cover main body 32, and a bent portion 38 that is bent at the protruding tip of the rib portion main body 36 and extends downward.

  Rainwater or the like enters the space formed by the door outer panel 20 and the door inner panel 22 from the accommodation opening of the window glass 18 formed at the upper end. Since the infiltrated rainwater or the like may enter the vehicle interior through the service hole 24 formed in the door inner panel 22, as a countermeasure, a service hole cover 30 that covers the service hole 24 from the inside is sealed. It is attached to the door inner panel 22 via the member 40. As a result, rainwater or the like passing through the service hole 24 travels down the outer surface of the service hole cover 30 as indicated by an arrow A in FIG. When the rib portion 34 according to the present embodiment is not provided, rainwater or the like that has fallen along the outer surface of the service hole cover 30 reaches the seal member 40 provided at the boundary portion with the door inner panel 22, and if necessary. Then, it is discharged from the discharge hole provided in the door inner panel 22 to the outside of the door inner panel 22 and further to the lower side of the vehicle. As a result, rainwater or the like entering the vehicle interior through the service hall 24 is reduced.

  In the present embodiment, a rib portion 34 that protrudes from the cover main body 32 of the service hole cover 30 through the service hole 24 toward the door outer panel 20 is provided. As the rib portion 34 covers the lower end edge 24b of the service hole 24 and the upper portion of the seal member 40, rainwater or the like flowing down the outer surface of the service hole cover 30 is shown in FIG. It flows toward the outside along the upper surface of the portion 34, and flows down from the outer end of the rib portion 34 downward to the vehicle. Thereby, the rain water etc. which flow down to the boundary part of the service hole cover 30 and the door inner panel 22 can be reduced.

  Further, the rib portion 34 is configured by the rib portion main body 36 and the bent portion 38 described above, and thus has a shape that is bent downward from a tip protruding outward from the cover main body 32. When the bent portion 38 extending downward from the outer front end of the rib portion main body 36 is not provided as in the present embodiment, rainwater or the like flowing outward along the upper surface of the rib main body 36 becomes water droplets on the lower surface side of the front end. There is a risk that the surface tension will flow toward the inner side of the lower surface of the rib portion main body 36 and reach the boundary between the service hole cover 30 and the door inner panel 22 due to surface tension. The sealing member 40 is provided at the boundary portion. However, if a gap is formed due to, for example, aging of the sealing member 40, water enters the vehicle interior through the gap. On the other hand, in the vehicle door portion structure 10 according to the present embodiment, the rain water or the like that flows along the upper surface of the rib portion main body 36 as shown by the arrow C in FIG. Flows along the outside of the bent portion 38 from the tip of the rib portion main body 36 and falls downward from the lower end of the bent portion 38. Therefore, the contact of rainwater or the like at the boundary between the service hole cover 30 and the door inner panel 22 is further suppressed, and as a result, the penetration of rainwater or the like from the boundary into the vehicle interior is prevented. The waterproofness of 30 can be remarkably improved.

  In the present embodiment, the rib portion 34 and the lower end edge 24b of the service hole 24 are separated in the vertical direction. Thereby, the contact with the rib part 34 and the door inner panel 22 at the time of assembling the service hole cover 30 is avoided, and the assemblability is improved. Further, when a rib structure close to the lower end edge 24b is provided, when the harness is routed so as to straddle the lower end edge 24b of the service hole 24, a through hole through which the harness passes is provided above the rib structure of the cover body 32. There is a risk that rainwater or the like may enter the passenger compartment from the through hole. On the other hand, in the vehicle door portion structure 10 according to the present embodiment, since the rib portion 34 is spaced upward from the lower end edge 24b of the service hole 24, the harness is disposed below the rib portion 34 of the cover body 32. A through hole can be provided. Since rainwater or the like does not pass through the through hole provided below the rib portion 34 having the bent portion 38, rainwater or the like can be prevented from entering the passenger compartment.

  In the above description, the rib portion 34 shown in FIG. 2 includes the rib portion main body 36 that extends substantially horizontally toward the outside and the bent portion 38 that extends downward from the outer end of the rib portion main body 36. However, if the lower end of the bent portion on the outer side (door outer panel 20 side) is located outside the boundary portion between the cover main body 32 and the door inner panel 22 when viewed from above, the shape of the rib portion is particularly The shape is not limited, and may be, for example, a shape gently curved downward from a base connected to the cover main body 32. In the above description, as shown in FIG. 1, the rib portion 34 is formed in an annular shape in a side view, but may be any shape as long as it covers the lower edge 24 b of the service hole 24 from above. A rib structure having a shape in which the protruding front end is bent downward may be formed in a band shape from the front end edge to the rear end edge in the lower portion of the cover main body 32.
