The door weather strip 55 is disposed along the periphery of the door panel 53a and the door sash 53b, and includes a loop-shaped extruded portion 55a formed by connecting several extruded portions in a loop shape. And a sash portion extruded portion 55b added to the extruded portion 55a and extending vertically. The sash portion extruded portion 55b is a seal portion for closing a gap between the door sash portions 53b of the front door 51 and the rear door 52 arranged side by side in the vehicle front-rear direction. As indicated by an arrow 9, wind, water, noise, and the like may enter the vehicle from the outside of the vehicle via the parting-off portion 56. For this reason, the conventional door weather strip 55 includes a loop-shaped extruded portion 55a.
A sash portion extruded portion 55b is provided separately from FIG.
As indicated by an arrow 0, the sash portion extruded portion 55b
This prevents wind, water, noise and the like from entering the vehicle.

When the door weather strip 55 is mounted on the rear door 52, a loop-shaped extruded portion 55a is provided above the belt line portion 57 of the rear door 52 as shown in FIGS.
As shown in FIG. 12, the belt line portion 57 is fixed by attaching a double-sided adhesive tape 59 to the side of the loop-shaped extruded portion 55a and the sash-portion extruded portion 55b that comes into contact with the door sash portion 53b. ing. Further, below the belt line, the loop-shaped extruded portion 55a is fixed at several places by clips (not shown). An outer weather strip 60 as an exterior component is mounted on the front door 51 and the rear door 52.
0, the tightening screw 61 is connected to the tightening portion 6 as shown in FIG.
By fastening to the door sash portion 53b, it is fixed to the door sash portion 53b.

[0004]

However, in the above-mentioned conventional door weather strip 55 mounting structure,
The sash portion extruded portion 55 is formed by the double-sided adhesive tape 59.
Since b is fixed, the sash extruded portion 55b is likely to be peeled off from the lower terminal due to a decrease in the adhesive force with the passage of time, and the appearance and the sealing function may be impaired. In addition, the sash portion extruded portion 5 using the double-sided adhesive tape 59
In the fixing method 5b, it is difficult to provide a guide for fixing the position. Therefore, a considerable skill is required for the mounting work, and there is a problem in workability.

The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent the seal portion of a door weather strip from peeling off without increasing the number of parts and the number of processing steps, and to provide the seal. It is an object of the present invention to provide a door weatherstrip mounting structure that can easily and surely position a part and can improve workability.
