[0009]

According to the present invention, there is provided a U-shaped door flange holding portion for mounting on a door flange of a door frame,
A run channel that seals between the door frame and the door glass, a door frame gripping part that is provided between the run channel and the door flange sandwiching part, and is attached to a mounting metal fitting in the door frame, and the door glass. A vehicle door seal body having a sub-seal covering the upper outer side of the door glass in a closed state, wherein the sub-seal has a cored bar so as to cover the upper outer side of the door glass. Located on the door seal.

What is most noticeable in the present invention is that the sub-seal covering the outside of the upper portion of the door glass has a built-in core metal. The sub-seal is integrated without any gaps particularly in the portion covering the door glass. Further, the sub-seal can be formed integrally with a door flange holding portion or the like. In this case, it is preferable that the core metal is continuously arranged between the door flange holding portion.

Next, it is preferable that the core metal is provided in a U-shaped cross section so as to cover the outer side, the upper side and the inner side of the upper portion of the door glass (see FIGS. 4 to 6). By this,
It is possible to prevent a tool from penetrating the seal portion between the door glass and the sub-seal to remove the door flange gripping portion from the door flange.

Next, the core metal preferably has a two-sheet structure. As a result, it is possible to further increase the strength of the portion of the core bar where rigidity is required. Also, when making a core by bending a single metal plate,
The folded-back portion can have a double-sheet structure (Fig. 1).
Next, the core metal is preferably formed integrally with the core metal in the door flange holding portion. Thereby, both can be molded as one member.

Next, it is preferable that the sub-seal has a seal lip at the tip thereof which comes into contact with the door glass. The seal lip is formed, for example, by bending the tip portion of the sub seal. In this case, the tip portion is a portion in which the core metal is not built. As a result, even if the door glass, the seal body, and the like have variations in size and the like due to manufacturing errors and the like, the seal does not become insufficient. In addition, the built-in core metal may cause the sub seal to lose some flexibility. In this case, the sealing lip can secure the sealing property with the door glass.

Next, various built-in states of the core metal can be considered as follows. First, there is a core bar having a substantially F-shaped cross section from one side wall of the U-shaped door flange holding portion to the other side wall of the door flange holding portion through the inside of the sub seal (Fig. 1). Some of the cored bars have a substantially F-shaped cross section that extends from one side wall of the U-shaped door flange holding portion to the other side wall through the other side wall (see FIG. 2).

Some of the cored bars have a substantially F-shaped cross section from the sub-seal to one side wall of the U-shaped door flange holding portion to the other side wall of the door flange holding portion. (Figure 3). In these three modes, the core metal is integrally formed continuously as described above, and it is easy to integrally form the door flange holding portion and the sub seal portion. Further, since the core metal is formed continuously, there is no weakened portion such as a joint portion, and the crime prevention property is further excellent.

Further, as another different mode, the core metal reaches the other side wall of the door flange holding portion from the sub seal through one side wall of the U-shaped door flange holding portion, and Some have an internal plate bent and extended inward from the door glass.

Some of the internal plates have an extended portion that is built in up to the door frame gripping portion. In some cases, the extending portion of the inner plate is fixed to the door frame by a fixture. In the case of the latter three types, the inner side of the door glass is also covered with the core metal, so that the crime prevention effect is further excellent.

[0018]

In the automobile door seal body of the present invention, the core metal is incorporated in the sub-seal covering the upper outside of the door glass. That is, when the door glass is lifted and closed, the cored bar arranged in the sub-seal covers the vehicle outer surface at the upper end of the door glass. Further, the sub-seal does not have a gap in the portion exposed to the outside unlike the conventional seal body.

Therefore, a tool or the like cannot be penetrated into the sub seal. Moreover, the tool cannot penetrate through the gap of the sub-seal. Therefore, it is possible to prevent the door glass from being pry open. As mentioned above,
ADVANTAGE OF THE INVENTION According to this invention, the sealing body of the automobile door excellent in crime prevention can be provided.
