Therefore, there is a problem that the workability of the door weather strip 5 deteriorates. Further, it is known that the door weather strip 5 is fixed to the door sash 3 by providing a fastener in the molding portion at a corner portion of the door weather strip 5, but the door weather strip 5 is not fixed due to variations in vehicle mounting. There was a misalignment.

Therefore, as shown in FIGS. 7 and 8, a hole 5d is made in a corner portion of the door weather strip 5, a cylindrical resin panel 8 for fixing the stud member 9 is fitted therein, and the tip portion 9a is previously attached. The door weather strip 5 is attached to the door sash 3 by inserting the stud member 9 that is fixed to the door sash 3 by welding into the resin panel 8.
It is known to be fixed to. According to this, since the insert member is not used, the cost does not become particularly high, and the position does not shift even if there is some variation when the vehicle is mounted, so that the appearance is not deteriorated.

[0005]

However, as shown in FIG. 8, the outer diameter L of the resin panel 8 is larger than the diameter R of the hole 5d provided at the corner portion of the door weather strip 5 (L> R). ), There is a problem that after the resin panel 8 is fitted into the hole 5d, deformation occurs around the hole 5d, or the resin panel 8 comes off. Further, since the stud member 9 is inserted into the resin panel 8 and the head portion 9b of the stud member 9 is stopped at the position where the head portion 9b of the stud member 9 abuts on the bottom portion of the resin panel 8, as shown in FIG. There is.
