It is configured.

  Next, the manufacturing procedure of the door 1 configured as described above will be described. First, in the sub-assembly line, the door module M is configured by assembling the door functional component, the screen 100 and the like to the lower trim component 41. Further, constituting the door body 4 by joining an inner panel 2 and the outer panel 3.

  Thereafter, in the main assembly line, the door module M is assembled to the door body 4 that is assembled in advance to the vehicle body. As described above, since the door module M assembled in the sub assembly line is assembled to the door body 4 in the main assembly line, the work in each assembly line can be simplified and the production efficiency of the door 1 is improved. Can be made. Further, when the door module M is assembled to the door body 4, the lower trim constituent member 41 is reinforced by the reinforcing member 70, so that the lower trim constituent member 41 is deformed or damaged by a load of the lifting device 7, the speaker 60, or the like. There is nothing. The main assembly line and the sub assembly line may be provided in the same factory or in different factories.

  Further, when the door module M is assembled to the door body 4, since the vertical dimension of the opening 23 of the inner panel 2 is shorter than the vertical dimension of the guide rail 26 of the door module M, the upper side of the guide rail 26 is from the lower side. After the entire door module M is tilted so as to approach the inner panel 2, the guide rail 26 is accommodated in the door bag portion 10 from above. At this time, the door trim 5 is divided into upper and lower parts to form the door module M with the lower trim constituent member 41 and the guide rail 26 protrudes upward from the upper edge of the lower trim constituent member 41. The part does not interfere with the inner panel 2, and the lifting device 7 can be easily accommodated in the door bag part 10.

  After the guide rail 26 of the elevating device 7 is accommodated in the door bag portion 10, the upper side of the guide rail 26 is coupled to the inner panel 2 with a nut 34. At this time, the fasteners 44 are engaged with the engagement holes 2 c, and the bolts 30 are screwed into the screwing members 31 to connect the lower trim constituting member 41 to the inner panel 2. The lower end of the guide rail 26 is coupled to the inner panel 2 by a bolt 30 that couples the lower trim component 41 to the inner panel 2. Further, when the door module M is assembled to the door body 1, the window glass 6 is fixed to the glass fixing member 25 of the lifting device 7.

  In the main assembly line, the screen 100 is integrated with the lower trim constituent member 41 in advance, so that the screen 100 is positioned only by assembling the door module M to the door body 4. As a result, the screen 100 can be easily and reliably adhered to the panel side seal portion 24 and the trim side seal portion 52. Further, since the panel-side seal portion 24 and the trim-side seal portion 52 are coupled by the bolt 30, even if the lower trim constituent member 41 and the inner panel 2 vibrate when the vehicle is running, for example, the screen 100 can be connected to both the seal portions 24. 52, the screen 10 and the seal portions 24, 53 are held in close contact with each other.

  Next, the upper trim component 40 to which the inner weather strip 20 is assembled is assembled to the door body 4.

  Therefore, according to the automobile door 1 according to this embodiment, the opening 23 of the inner panel 2 is covered with the elastically deformable screen 100, and the screen 100 is compressed by the panel side seal portion 24 and the trim side seal portion 52. In this state, since the gap between the periphery of the opening 23 of the inner panel 2 and the lower trim component 41 is sealed, water and dust that have entered the door bag portion 10 through the slit 13 enter the interior of the vehicle interior from the opening 23. In addition, the noise outside the passenger compartment can be prevented from entering the passenger compartment, and the quietness of the passenger compartment can be ensured.

  Further, since the screen 100 constitutes the door module M, the screen 100 can be assembled to the door body 4 simultaneously with the lower trim constituting member 41 and the lifting device 7 and the like, and when the screen 100 is provided as described above. The increase in man-hours in the main assembly line can be suppressed. Further, it is possible to prevent the screen 100 is located offset from the panel side seal portion 24 and the trim side seal portion 52.

  Further, since the panel side seal portion 24 and the trim side seal portion 52 are coupled, both the seal portions 24 and 52 can be reliably brought into pressure contact with the screen 100. Further, at this time, the rib 52b is brought into pressure contact with the screen 100, so that the pressure acting on the screen 100 is increased and the screen 100 can be brought into close contact with the panel side seal portion 24. As a result, the seal between the periphery of the opening 23 of the inner panel 2 and the lower trim component 41 can be further ensured.

  Further, since the screen 100 is formed along the outer side of the lower trim constituent member 100, it is possible to prevent the assembled screen 100 from strongly interfering with the lower trim constituent member 41 or touching the wind glass 6 that is being lifted or lowered. It is possible to prevent the screen 100 from being damaged.

  Further, since the screen 100 is made of a foam material, a large number of bubbles of the foam material face the door bag portion 10 from the opening 23 of the inner panel 2, so that the screen 100 can absorb noise. This can improve the quietness of the passenger compartment.

  In this embodiment, the rib 52 b is provided on the trim side seal portion 52, but a similar rib may be provided on the panel side seal portion 24.
