In recent years, there has been a tendency to partially abolish reinforcement, which is a reinforcing material for the inner panel of a vehicle door (hereinafter referred to as “door”), due to demands for weight reduction of automobiles and the use of high-tensile steel plates for door panels. It is in. In this structure in which the reinforcement is partially abolished, when the weather strip is attached to the upper end of the inner panel, the upper end of the inner strip is thin, so that the interior weather strip is not attached to the flange. Become stable.
Therefore, a means for fixing the weather strip to the upper end portion of the door trim as an interior material of the door can be considered. However, in this means, the weather strip is moved from the target position due to deformation of the door trim or a decrease in the installation accuracy of the door trim. The position was shifted and the weatherstrip sealability to the window glass was liable to deteriorate.
The present invention has been made in view of the above circumstances, and its purpose is to stabilize the state of attachment to the upper end of the inner panel even if the reinforcement as a reinforcing material for the inner panel is partially abolished. It is possible to provide a weather strip mounting structure on the indoor side that can improve the sealing performance against the window glass.

The feature of the present invention is that
