<Operation of guide wall>
When washing the vehicle, an operator may wash the plate mounting portion 13 in the vicinity thereof together with the license plate 101 with washing water. Depending on the direction in which the cleaning water is applied at this time, as shown in FIG. 7, the cleaning water enters the accommodation space S <b> 2 through the knob opening 63 and the light projection opening 65 formed in the outer stepped portion 61 of the plate mounting portion 13. Get in.

  Here, since the seal part 89 is formed around the knob opening 63 and the light projection opening 65 in the rear opening / closing panel 1, the seal part 89 is formed in a good state and exhibits a sufficient sealing performance. If so, the cleaning water that has entered the housing space S2 is blocked by the seal portion 89, and the cleaning water can be prevented from entering the internal space of the door body.

  However, in the seal portion 89, particularly in the bonded portion between the seal groove 85 portion of the side stepped portion 77 and the outer stepped portion 61, the adhesive 84 is scraped off when the outer lower panel 47 is assembled to the inner panel 3, resulting in poor adhesion. It is likely to occur.

  That is, in the assembling work of the outer lower panel 47 to the inner panel 3, after the adhesive 84 is applied to the bonded portion including the seal groove 85 of the inner panel 3, the outer lower panel 47 is connected to the lower extending portion 53. 3, and the positioning projection 19 is inserted into the positioning hole 55 of the lower extension 53 in a posture in which the latch mounting portion 31 is inclined so as to be relatively separated from the inner panel 3. The inner panel 3 is positioned, and in this state, the outer lower panel 47 is rotated in a direction in which the latch mounting portion 31 approaches the inner panel 3 and is adhered to the inner panel 3 by being overlapped. At this time, the lower end portion of the outer stepped portion 61 hits the adhesive 84 applied to the seal groove 85 portion of the side stepped portion 77 and is scraped off while passing between the seal groove 85 portion of the side stepped portion 77 and the outer stepped portion 61. easy. As a result, a gap is formed between the seal groove 85 portion and the outer step portion 61, and adhesion between the seal groove 85 portion of the side step portion 77 and the outer step portion 61 at the seal portion 89 is impaired. Invite a defect.

  In this way, if a bonding failure occurs in a portion of the seal portion 89 where the seal groove 85 portion of the side step portion 77 and the outer step portion 61 are bonded, the entry into the accommodation space S2 from the knob opening 63 or the light projection opening 65. However, the cleaning water leaks from the poorly bonded portion to the outside of the seal portion 89 and flows into the internal space S1 of the door body 7. The cleaning water leaked to the outside of the seal portion 89 is the first inner guide. The gap 91 between the wall 91 and the outer guide wall 93 is guided downward by its own weight while being held by the surface tension, and below the outer guide wall 91 of the first inner guide wall 93 from the gap t on the plate fastening portion 41 side. After flowing along the portion extending to, the plate fastening portion 41 is released to the outside in the vehicle width direction by the recess 90.

  When the rear opening / closing panel 1 is in the closed state, the plate fastening portion 41 passes through a portion of the first inner guide wall 91 extending below the outer guide wall 93 from the gap t between the first inner guide wall 91 and the outer guide wall 93. The washing water released in the vehicle slides down along the longitudinal guide wall 99 due to its own weight outside the working opening 69 in the vehicle width direction, and along the rear surface of the vertical wall portion 15 of the inner panel 3, the working opening 69 is formed. After being guided to the drainage hole 33 while avoiding, it is discharged from the drainage hole 33 to the outside.

  Further, when the rear opening / closing panel 1 is in the open state, the plate is fastened through a portion extending below the outer guide wall 93 in the first inner guide wall 91 from the gap t between the first inner guide wall 91 and the outer guide wall 93. Since the wash water released to the recessed portion 90 of the portion 41 is restricted from moving toward the longitudinal guide wall 99 by a step (a step located below in the closed state) behind the recessed portion 90, the recessed portion It is guided in a direction away from the work opening 69 through the lower lateral guide wall 97 and the upper lateral guide wall 98 from the outer open end of the portion 90 in the vehicle width direction, and then the rear opening / closing panel 1 is in the closed state. When it is done, it slides down along the rear surface of the vertical wall portion 15 of the inner panel 3 and is discharged from the drain hole 33 to the outside. Thereby, it is possible to prevent the cleaning water from entering the vehicle interior opening 69 even if the cleaning water splashes in the internal space S1 of the door body 7 due to the opening / closing operation of the rear opening / closing panel 1.
