  Next, an operation when the back door 11 of the present embodiment is opened, for example, during rain or after a car wash will be described.

  When the back door 11 is in an open position in order to take out, for example, luggage in a luggage room during rain or after washing, as shown in FIG. 2, the front end of the back door 11 in the vehicle front-rear direction (the vehicle in the closed position of the back door 11) The upper end 13 in the vertical direction is positioned below the rear end in the vehicle front-rear direction (the lower end 15 in the vehicle vertical direction 15 when the back door 11 is closed). Therefore, when the back door 11 is in the open posture, an inclined surface of the back door glass 67 that is directed downward in the vehicle is formed toward the front of the vehicle. Therefore, a part of the water received on the back door glass 67 and the water adhering to the surface of the back door glass 67 is on the vehicle front side along the surface of the back door glass 67 as shown by the white arrow in FIG. Washed away. This water is received by the lower spoiler portion 51 of the outer upper panel 37 and is formed between the lower spoiler portion 51 and the front end of the back door glass 67 in the vehicle front-rear direction (the vehicle upper-lower direction upper edge 68 in the closed posture). The first gap 69 flows. As a result, the water that has flowed from the first gap 69 is temporarily stored in the recess 53 of the outer upper panel 37.

  When the back door 11 is open, the vehicle width of the first gap 69 formed between the front end of the back door glass 67 in the vehicle front-rear direction (the vehicle up-down direction upper edge 68 in the closed posture) and the lower spoiler portion 51. The water that has flowed to the center in the direction flows to the recess 53 using a part of the inner side wall 63 of the outer upper panel 37 as a guide. That is, when the back door 11 is opened, the water that has flowed to the center in the vehicle width direction of the first gap 69 is, as shown in FIG. 4B, the straight portion 41 of the glass joint portion 39 of the outer upper panel 37. To be accepted. A part of the inner side wall portion 63 of the outer upper panel 37 serves as a guide portion, and water flows into the concave portion 53. As a result, water is temporarily stored in the recess 53.

  On the other hand, since the back door glass 67 is curved in the vehicle width direction, the water received by the back door glass 67 and a part of the water adhering to the back door glass 67 are indicated by white arrows in FIG. As shown, it flows along the back door glass surface outward in the vehicle width direction. The water that has flowed outward in the vehicle width direction is hung from the vehicle width direction end portion of the back door glass 67 and is received by the lip portion 77 of the molding 73 provided on the outer upper panel 37. Then, water droplets are formed on the upper surface of the lip portion 77 of the molding 73. When the water droplets become large, they are caused to flow toward the concave portion 53, and water is temporarily stored in the concave portion 53.

  For example, when the luggage in the luggage room has been taken out and the back door 11 starts to close or closes, the water temporarily stored in the recess 53 is caused to flow downward in the recess 53 to the back door glass 67. The water is drained from the second gap 71 (drainage portion) between the outer upper panel 37 and the outer upper panel 37.

  According to the above configuration, when the back door 11 is open, the water adhering to the surface of the back door glass 67 can be temporarily stored in the recess of the outer panel 33, and when the back door 11 is closed, The water temporarily stored in the recess 53 is drained. Therefore, even when the water received by the back door glass 67 flows along the back door glass 67 when the back door 11 is in the open posture, the water can be prevented from falling from the back door 11.

  Moreover, since the recessed part 53 is integrally molded by the outer upper panel 37, compared with the case where another member is provided only for the recessed part 53 and it fixes to the outer upper panel 37, an additional member is not required. Furthermore, since the back door panel 27 is made of resin in the above embodiment, the recess 53 can be easily and deeply formed, and a sufficient capacity can be secured.

  Further, since water is caused to flow from the first gap 69 to the recess 53, a separate member that allows the water received by the back door glass 67 or the water adhering thereto to flow into the recess 53 is not required. Therefore, water can be temporarily stored in the recess 53 without providing an additional member. Further, the second gap 71 is provided between the both ends in the vehicle width direction of the back door glass 67 and the both ends in the vehicle width direction of the outer upper panel 37 in the vehicle front-rear direction when the back door 11 is closed. Therefore, the water temporarily stored in the recessed part 53 can be discharged | emitted out of a vehicle, without providing an additional member.

  Moreover, since the recessed part 53 is provided in the vehicle up-down direction upper end side of the outer upper panel 37 at the time of the back door 11 closing posture, the 1st clearance gap 69 and the recessed part 53 adjoin. Therefore, water can be easily stored in the recess 53. Furthermore, since the recessed part 53 is provided in the vehicle width direction both sides of the outer upper panel 37, and the 2nd clearance gap 71 is also provided in the vehicle width direction both ends, the recessed part 53 and the 2nd clearance gap 71 adjoin. Therefore, water can be easily drained.

  In FIG. 6, when the back door 11 is open, the outer end 65 may be inclined downward in the vehicle vertical direction from the outer side in the vehicle width direction toward the inner side in the vehicle width direction. In such a case, the water received on the upper surface of the molding 73 flows into the recess 53 due to the inclination of the outer end portion 65 of the outer upper panel 37 to which the molding 73 is attached. As a result, water is temporarily stored in the recess 53.

  In the above embodiment, the outer end panel 65 of the outer upper panel 37 is provided with a molding 73 that hides a part of the second gap 71 (drainage part) between the vehicle body and the back door glass. . However, as shown in FIG. 7, the molding 73 is fitted between the outer upper panel 37 and the inner panel 29, and the vehicle width direction outer end portion of the molding 73 is the vehicle width direction end portion of the back door glass 67. It may be located outside in the vehicle width direction. Note that the molding 73 conceals the gap between the back door panel 27 and the back door glass 67 except for the portion where the second gap 71 is provided in the vehicle vertical direction.

  According to the above configuration, the fixing means (adhesion) between the molding 73 and the outer upper panel 37 becomes unnecessary, so that the fixing means can be reduced and the cost can be reduced.

  Although the embodiments and the modifications thereof have been described above, the embodiments of the present invention are not limited to these embodiments, and various other embodiments can be adopted without departing from the gist of the present invention. That is, the fixing means is not necessarily limited to bonding, and for example, the back door glass 67 and the outer panel 33 may be formed by making holes in the back door glass 67 and fixing them with bolts.

  Further, the bottom portion 57, the inner side wall portion 63, the outer side wall portion 61, and the lower wall portion 59 of the concave portion 53 are not formed to be bent but may be curved. Moreover, the depth of the recessed part 53 may be set so that it may become deep toward the vehicle width direction both sides from the vehicle width direction center side. In this case, when the back door 11 is in the open posture, water that has flowed forward in the vehicle width direction center of the surface of the back door glass 67 to the front of the vehicle flows into the first gap 69 between the back door glass 67 and the air spoiler 47. The water that has flowed into the first gap 69 is received by the straight portion 41 of the glass joint portion 39 of the outer upper panel 37. At this time, since the depth of the recessed portion 53 becomes deeper (inclined) toward the outer side in the vehicle width direction, this inclination serves as a guide portion, and water is guided to the recessed portion 53. Therefore, water can be easily stored in the recess 53.

  In addition, when the recess 53 is in the closed posture of the back door 11, the lower side of the vehicle is formed shallower than the upper side of the vehicle, and the lower side of the vehicle communicates with the second gap 71. Are collected from one place and drained, and all the water temporarily stored in the recess 53 can be drained.

  Further, in the above embodiment, the recesses 53 are provided at both ends in the vehicle width direction and at the upper end in the vehicle vertical direction, but from the first gap 69, when the back door 11 is closed, the recesses 53 are directed downward toward the outside in the vehicle width direction. It may be configured such that water is stored in the recess through the first connecting water channel having an inclination.

  A recess is provided on the upper end in the vehicle vertical direction closer to the center than both ends in the vehicle width direction. The recess and the drainage portion are connected to each other, and the back door 11 is inclined downward toward the outside in the vehicle width direction when the back door 11 is closed. Two connecting water channels may be provided. In this case, the water that has flowed along the surface of the back door glass 67 when the back door 11 is in the open position to the front end in the vehicle front-rear direction of the back door glass 67 (the vehicle upper and lower direction upper edge 68 in the closed position) 69 flows through the recess. Since the concave portion faces downward in the vehicle width direction when the back door 11 is closed, the water that has flowed into the concave portion flows down due to the inclination, and the water is easily drained from the drainage portion.

  In the above-described embodiment, the back door 11 is described as an example of a door that can turn the vehicle vertical direction lower end side 15 upward with the vehicle vertical direction upper end side 13 as a rotation axis. For example, a gull-wing door that opens and closes an opening for passenger entry / exit may be used. Moreover, in the said embodiment, although the back door panel 27 is made from resin and is comprised by the inner panel 29, the outer upper panel 37, and the outer lower panel, it does not need to restrict to this.
