For this reason, the water that has entered between the frame molding 36 and the recess 26 mainly flows down between the lip 54 and the base 50 of the upper weather strip 48. The water that has entered between the mounting groove 38 and the base 50 flows down between the lip 54 and the base 50 located on the lower side of the vehicle.

  Here, the dam 56 of the upper weather strip 48 seals between the frame molding 36 and the base 50 and the lip 54. For this reason, the water flowing down between the base 50 and the lip 54 is discharged by the dam 56 to the outside of the front door 28 in the vehicle.

  In addition, the rib 52 and the intrusion portion 58 of the upper weather strip 48 seal between the mounting groove 38, the base portion 50, and the dam 56 in a state where the rib 53 of the upper weather strip 48 contacts the side surface of the mounting groove 38. For this reason, water flowing down between the base 50 and the lip 54 and discharged by the dam 56 is prevented from flowing down between the mounting groove 38 and the base 50.

  As a result, the water flowing down between the frame molding 36 and the upper weather strip 48 can be discharged to the outside of the vehicle of the front door 28. Therefore, the water flowing down between the frame molding 36 and the upper weather strip 48 flows from between the vehicle lower end of the frame molding 36 and the vehicle lower end of the upper weather strip 48 (position F in FIG. 3). 14 and the front door 28 can be prevented from entering the parting 60 (see FIG. 3) between the front side edges of the vehicle, and freezing of the front door 28 due to water coagulation (freezing of the door hinge portion) can be suppressed.

  Further, the ribs 52 and 53 are brought into contact with both side surfaces of the mounting groove 38, and the intrusion portion 58 seals between the rib 52, the mounting groove 38 and the dam 56. For this reason, it is possible to reliably seal the mounting groove 38, the base 50, and the dam 56.

  Furthermore, ribs 52 and 53 and an intrusion portion 58 are provided on the vehicle upper side (upstream side of the water flow) of the dam 56. Therefore, it is possible to satisfactorily prevent water flowing between the base 50 and the lip 54 and discharged by the dam 56 from flowing between the mounting groove 38 and the base 50, and the frame molding 36 and the upper weather. The water flowing down between the strips 48 can be well discharged to the outside of the front door 28 on the vehicle.

  Moreover, the position D in FIG. 3 (the front of the side member 16 is located) where the dam 56 is located on the inner side in the vehicle front-rear direction of the front door 28 from the intersection position E (see FIG. 3) of the outer peripheral surface of the frame molding 36 with the main body 30. Pillar position). For this reason, the water discharged to the vehicle outer side of the front door 28 by the dam 56 flows down the vehicle at the intersection E with the main body portion 30 on the outer peripheral surface of the frame molding 36, and the front side edge of the fender panel 14 and the front door 28 on the vehicle. It is possible to suppress intrusion into the parting space 60 between them, and it is possible to reliably suppress freezing of the front door 28 due to water coagulation.

  When the upper weather strip 48 is assembled to the front side portion 32A of the door frame portion 32, the mounting portion of the general portion 48A of the upper weather strip 48 from the corner portion 32C at the vehicle upper side end and the vehicle rear side end of the front side portion 32A. 44 is slid along the mounting groove 40 of the front side portion 32 </ b> A, and the base 50 in the general portion 48 </ b> A of the upper weather strip 48 is slid along the mounting groove 38 of the frame molding 36. Thereafter, the mounting portion 44 in the mold portion 48B of the upper weather strip 48 is pushed into the mounting groove 40 to be elastically deformed and attached to the mounting groove 40, and the base portion 50 (ribs) in the mold portion 48B of the upper weather strip 48 is provided. 52, 53) is pushed into the mounting groove 38, and the base 50 is mounted (fitted) into the mounting groove 38 while being elastically deformed.

  As described above, in the general portion 48 </ b> A of the upper weather strip 48, there are gaps between the attachment portion 44 and the attachment groove 40 and between the base portion 50 and the mounting groove 38. Therefore, in the general portion 48 </ b> A of the upper weather strip 48, the attachment portion 44 is slid along the attachment groove 40 and the base portion 50 is slid along the attachment groove 38. On the other hand, in the mold part 48 </ b> B of the upper weather strip 48, ribs 52 and 53 are formed on the base part 50, and it is difficult to slide the base part 50 along the mounting groove 38. For this reason, in the mold portion 48B of the upper weather strip 48, the attachment portion 44 is attached by being pushed into the attachment groove 40 without sliding along the attachment groove 40, and the base portion 50 is not slid along the attachment groove 38. Push into the mounting groove 38 to mount. Thereby, the upper weather strip 48 can be easily assembled to the front side portion 32 </ b> A of the door frame portion 32. That is, since the ribs 52 and 53 are formed on the upper weather strip 48 only in the range C of FIG. 3, the ribs 52 and 53 are formed on the upper weather strip 48 in the entire longitudinal range of the front side portion 32A of the door frame portion 32. As compared with the case where the upper weather strip 48 is formed, the process of pushing into the mounting groove 40 and the mounting groove 38 can be reduced when the upper weather strip 48 is assembled, and workability can be improved.

  Furthermore, since the base portion 50 is brought into contact with both side surfaces of the mounting groove 38 at the ribs 52 and 53, it is possible to suppress the upper weather strip 48 from being detached from the mounting groove 38.

  In the present embodiment, the ribs 52 and 53 are formed in the base 50 in the range C in FIG. 3, but the ribs 52 and 53 are also formed in the base 50 on the vehicle lower side in the range C in FIG. It is good also as a structure.

  In the present embodiment, the present invention is applied to the front door 28 of the vehicle 12. However, the present invention may be applied to another door (for example, a rear door) of the vehicle.
