A weatherstrip door glass inner is mounted inside and a weatherstrip door glass outer is mounted outside the door glass. The structure of the connecting portion between the door weather strip and the weather strip door glass inner (hereinafter referred to as the weather strip inner) is as follows.
For example, as shown in FIG. FIG. 6 is the same as FIG.
FIG. 2 is a view of a Z portion of a front door 1 of the automobile viewed from the inside. As shown in FIGS. 5 and 6, the door glass 2 can be stored inside the front door 1.
The upper and lower portions can be moved up and down through a weatherstrip door glass outer (not shown) mounted on the upper edge portion 3 and a weatherstrip inner 4. The front surface (side surface of the vehicle interior) of the weatherstrip inner 4 is covered by an upper portion of the door trim 5, and both ends in the longitudinal direction are cut in a stepped shape, and the door weatherstrip is mounted on the outer peripheral edge of the front door 1. 6 are connected to the upper end of the leading edge and the upper end of the trailing edge, respectively.

That is, the weather strip inner 4
The structure of the connecting portion between the door weather strip 6 and the door weather strip 6 is as shown in FIG. 7 or FIG. In the case of FIG. 7, in the upper end portion 6A of the rear edge of the door weather strip 6, the cover 6B covering the upper corner of the rear edge of the front door 1 has its edge facing the weather strip inner 4 side. It is formed into a shape cut in steps. On the other hand, the rear end of the weatherstrip inner 4 is at the upper end 6A of the rear edge of the door weatherstrip 6.
Is cut by a punching blade along the stepped cut of the cover portion 6B. If the various conditions at the time of installation are appropriate, the rear end of the weatherstrip inner 4 and the cover 6B of the upper terminal 6A at the rear edge of the door weatherstrip 6 are connected with no gap and mounted. And present an integrated appearance. However, if each part has a variation in dimensions at the time of molding or a variation in mounting, a gap S is generated between the two parts, an overlapping protrusion is generated, and the appearance is impaired. Had become. Further, the weatherstrip inner 4 shrinks due to a change with time, and a gap S may be generated between the two, or the gap S may be enlarged.

The conventional example shown in FIG. 8 is an example in which a stainless steel molding 9 is formed on the upper surface of the weather strip inner 8. It is difficult to cut the weatherstrip inner 8 at a time with a punching blade as in the conventional example shown in FIG. 7 described above. It is necessary to cut by two operations of cutting (vertical direction) below the part.
In addition, since the end portion of the stainless steel molding 9 also requires chamfering, a considerable increase in cost was unavoidable. If there is a variation in the mounting or a change with the lapse of time in the same manner as described above, the rear end of the weatherstrip inner 8 and the cover 6B of the upper terminal 6A at the rear edge of the door weatherstrip 6 will not move. There was a case where the gap occurred and a step was generated.

[0005]

According to this invention, a gap is formed due to a dimensional variation due to molding or mounting as seen in the above-mentioned conventional example, a shrinkage due to a change with time, and a stainless steel molding is formed. It is an object of the present invention to provide a door weatherstrip and a weatherstrip inner mounting structure which do not cause an appearance defect such as a step in the weatherstrip inner.
