Description

  The present invention relates to a glass run mounting structure that is mounted on a vehicle door.

  A glass run for guiding the raising and lowering of the door glass and sealing between the door glass and the door frame is attached to the inner peripheral side of the door frame of the vehicle door having the door glass that moves up and down.

  There is a sharp corner at the top of the door frame, and the corners around the corner of the glass run corresponding to this are the extrusion parts corresponding to the upper and vertical sides of the door frame, and the ends of these extrusion parts. It is formed by the corner type molding part which connects each other.

  On the other hand, a weather strip that seals between the door opening periphery and the door frame is attached to the periphery of the door opening of the vehicle body that faces the door frame when the door is closed. Among these, the curvature of the corner portion of the door opening peripheral edge facing the acute corner portion of the door frame is smaller than the curvature of the corner portion of the door frame. Therefore, a gap where the weather strip does not come into contact with the door frame is formed between the acute corner portion of the door frame and the corner portion on the peripheral edge of the door opening.

In order to deal with such problems, in recent years, there are also provided with a corner piece that fills the gap in the corner (see, for example, Patent Document 1).
JP-A-8-230465

  However, if the corner piece is directly visible from the outside of the vehicle, the appearance quality may be degraded. On the other hand, it has been studied to improve the appearance quality by covering the corner piece with an extending wall portion extending from the inner side wall of the glass run to the inner side of the glass run at the corner portion of the glass run.

  However, the extension wall portion follows the movement of the seal lip accompanying the sliding of the door glass, for example, and the tip end portion (inner peripheral side edge portion) is lifted, and a gap is formed between the extension piece and the corner piece. There is a risk that. Therefore, it is also considered that a locking portion is provided in the vicinity of the distal end portion of the extending wall portion, and the locking portion is locked to a corner piece to prevent the lifting.

  When such a configuration is adopted, the outer edge of the wall of the corner portion on the inner peripheral side of the corner piece is generally bent into an acute angle (undercut) and locked to the back side of the bent portion. The part will be hooked.

  However, in such a configuration, although it is locked in the vehicle outer direction, when the extension wall is subjected to stress in the sash direction (periphery side direction), the locking portion is a corner piece. There is a possibility that it will come off from the bent part. For example, the glass run may be subjected to stress due to distortion at the time of mounting the glass run in addition to stress due to sliding of the door glass. The glass run is formed in a state in which a main body portion having a substantially U-shaped cross section is developed for the convenience of molding. When the molded part of the glass run is fitted into the sash, the main body is narrowed from the developed state to the non-deployed state having a substantially U-shaped cross section. For this reason, in the mold forming part corresponding to the corner part, the peripheral length and the like change between the inner peripheral side and the outer peripheral side, and stress in the outer peripheral side direction may be applied to the extending wall part. Therefore, there is a possibility that the extended wall portion may still be lifted only by providing the locking portion as described above. Furthermore, if the end of the corner piece is bent, depending on the relationship with other parts, it may be difficult to remove the die at the time of molding the corner piece.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to suppress the lifting of the extended wall portion of the corner portion of the glass run, and to improve the appearance quality of the glass run. An attachment structure is provided.
