2. Description of the Related Art Generally, a glass run is provided on the periphery of a door glass of a vehicle such as an automobile. The glass run has a main body having a substantially U-shaped cross section, and a pair of lips extending inward from the substantial ends of both side walls of the main body. Then, the main body is attached to a sash or the like provided on the door of the vehicle, and the inside and outside of the door glass are sealed by the pair of seal lips.

On the other hand, an inner weather strip located on a door trim side as an interior component is provided on a belt line below a door window. For example, as shown in FIG.
And seal lips 53 and 54 extending from the base 52 and abutting against the inside surface of the door glass, so that the interior of the inner panel 57 and the door glass are sealed by the presence of the seal lips 53 and 54. It has become. The inner weather strip 51 has a substantially linear shape along the belt line, and has a metal insert 55 embedded therein to ensure a predetermined shape retention. The lower end of the insert 55 is in an exposed state, and the exposed part is a mounting part 56. Then, the attachment portion 56 is attached and fixed with a rivet or the like in a state where the attachment portion 56 is in contact with a predetermined surface of the inner panel 57 (for example, a vehicle inner side surface).

Heretofore, these glass runs and inner weather strips have been manufactured separately and assembled to doors. For this reason, there is a possibility that a gap may be formed between the lip portions at the point where the glass run and the inner weather strip intersect (both ends of the inner weather strip). Therefore, it is conceivable to integrally connect the glass run and the inner weather strip (see Japanese Patent Application Laid-Open No. 8-25976). In this way, by connecting the two by the die molding method,
A situation where a gap is formed between the seals is avoided,
It is possible to expect an improvement in sealing performance.

[0005]

However, when assembling the inner weather strip in which the glass runs are integrally connected, the following problems occur. That is, as an assembling procedure, it is conceivable to first assemble the glass run. Then, as shown in FIG. 7, finally, the inner weather strip 51 is attached and fixed to the inner panel 57. Here, as described above, the mounting portion 56 of the insert 55 is
7, the insert 55 needs to be positioned on the predetermined surface side when the assembling of the glass run is substantially completed.

However, as shown in FIGS. 7 (a) to 7 (c), an insert 55 (attachment portion 56) which normally has to be guided to a predetermined surface side (left side in the figure) of the inner panel 57 is provided. At times, there is a possibility that the user will be guided to the opposite side (right side in the figure). Then, as shown in FIG. 7C, once the insert 55 is guided to the opposite side, the inner weather strip 51 itself has rigidity and extends over almost the entire width of the belt line. Therefore, it is impossible to guide only the inner weather strip 51 to the predetermined surface side by bending. Therefore, in this case, it may be necessary to remove all the glass runs once assembled and perform the assembly work again from the beginning.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to dramatically improve the workability in assembling and mounting while improving the sealing performance. It is to provide a possible inner weather strip.
