The formed door molding decorative part 52 covers the tip of the door frame 2 and forms a decorative part on the outer periphery of the door frame 2.

The end portion of the door molding decorative portion 52 is bent toward the back side in the form of a hairpin to form a door molding holding portion 53. The door molding holding portion 53 is fitted in a vehicle outer side holding recess 25 described later and holds the vehicle outer side wall 20.
Note that the glass run 10 can be held by bending the door frame 2 to form the channel 3 having a substantially U-shaped cross section without using the door molding 50.

The present invention relates to the glass run upper side portion 13 attached to the upper side of the door frame 2 in the glass run 10.
The cross-sectional shape of the glass run 10 will be described based on FIG. 1, and the state where the glass run 10 is attached to the door frame 2 will be described based on FIG.

The cross-sectional shape of the glass run upper side portion 13 attached to the upper side portion of the door frame 2 is substantially the same as that of the glass run main body 16 from the vehicle outer side wall 20, the vehicle inner side wall 30, and the bottom wall 40 as shown in FIG. It is formed in a U shape. As will be described later, the vehicle interior side wall 30 is larger than the vehicle exterior side wall 20 and is thick, and the substantially U-shaped cross section is formed in an asymmetric shape with a large vehicle interior. 1 is a cross-sectional view taken along line AA in FIG.
The glass run main body 16 basically has a substantially U-shaped cross-section in both the portion attached to the upper side portion of the door frame 2 and the portion attached to the vertical side portion.

As shown in FIG. 1, the vehicle outer side wall 20 of the glass run body 16 is formed in a substantially plate shape in cross section.
A vehicle exterior seal lip 21 extends from the vicinity of the front end of the vehicle exterior side wall 20 toward the inside of the glass run body 16 having a substantially U-shaped cross section. Further, the vehicle outer side cover lip 22 is extended from the front end of the vehicle outer side wall 20 in the vehicle outer direction. As shown in FIG. 2, the vehicle outer side cover lip 22 covers the ends of the door molding decorative portion 52 and the door molding holding portion 53 that are bent in a hairpin shape of the door molding 50.

  On the outer surface of the vehicle outer side wall 20, a vehicle outer protrusion 23 is formed on the bottom wall 40 side of the outer surface of the vehicle outer side wall 20. A vehicle exterior holding recess 25 is formed between the vehicle exterior projection 23 and the vehicle exterior cover lip 22. As shown in FIG. 2, the door molding holding portion 53 of the door molding 50 is fitted into the vehicle exterior holding recess 25 to hold the vehicle outer side wall 20.

  Thereby, the vehicle outer side wall 20 can be reliably held by the door molding 50. Therefore, even if the door glass 5 is moved up and down, it is dragged by the door glass 5 so that the vehicle outer side wall 20 is not detached from the door molding 50, and the door glass 5 does not protrude to the vehicle outer side. The aesthetics from can be improved.

  The vehicle outer side wall 20 is formed of a thermoplastic elastomer rubber solid material or a fine foam solid material. For this reason, the rigidity is high, and when the door glass 5 rises and enters the main body of the glass run 10, the front end of the door glass 5 is displaced, and the front end of the door glass 5 contacts the front end of the vehicle outer side wall 20. Even in the case of contact, the vehicle outer side wall 20 does not deform abnormally, and the sealing performance can be ensured reliably. Furthermore, coupled with the fact that the vehicle exterior holding recess 25 is held by the door molding 50, the glass run 10 does not jump out of the door frame 2, and the appearance is good.

The vehicle interior holding lip 34 engages with a panel second recess 2g formed in a portion near the panel front end 2h of the outer panel 2c, and holds the root portion of the vehicle interior side wall 30.
For this reason, the vehicle inner side wall 30 can be reliably held together with the holding effect of the vehicle inner protrusion 33 and the vehicle inner holding lip 34.

  The vehicle interior side wall 30 is connected to the bottom wall 40 by a vehicle interior connection portion 36. A groove portion is formed on the inner surface of the vehicle inner side connection portion 36, and when the glass run 10 of the channel 3 is attached, the vehicle inner side connection portion 30 is easily bent between the vehicle inner side wall 30 and the bottom wall 40 like the vehicle outer side connection portion 26. Becomes easier. A sloped vehicle interior side wall inclined surface 37 is also formed on a portion of the base portion of the vehicle interior side wall 30 that is continuous with the vehicle interior connection portion 36 and that faces a bottom wall vehicle interior first inclined wall 47 described later. ing.

  The vehicle interior seal lip 31 extends obliquely from the front end of the vehicle interior side wall 30 toward the inside of the main body of the glass run 10. As described above, both side surfaces of the front end portion of the door glass 5 are held by the vehicle inner seal lip 31 and the vehicle outer seal lip 21. As the door glass 5 moves up and down, the vehicle inner side seal lip 31 and the vehicle outer side seal lip 21 come into contact with the side surface of the door glass 5, and the door frame 2 and the door glass 5 can be sealed.

  The vehicle interior seal lip 31 is formed of a solid material of thermoplastic elastomer or a fine foamed solid material, like the vehicle exterior seal lip 21. The vehicle interior seal lip 31 can be formed of a solid material or a fine foamed solid material, improving the holding power of the door glass 5 and the rigidity of the interior of the glass run 10 to improve durability, and the surface Is smooth and improves aesthetics. The vehicle interior seal lip 31 uses the same material as the vehicle exterior side wall 20.

As described above, the low sliding member layer can be formed on the surface of the vehicle interior seal lip 31. In this case, sliding resistance between the vehicle inner side seal lip 31 and the vehicle inner side auxiliary seal lip 38 and the door glass 5 can be reduced, and the smooth raising and lowering of the door glass 5 can be maintained.
The low sliding member layer can be formed by applying a material having a small sliding resistance, a silicon resin, or a urethane resin having a large ratio of the olefin portion of the same thermoplastic elastomer as the vehicle exterior seal lip 21.

  The bottom wall 40 includes a bottom wall main body 46 formed in a plate shape, and a bottom wall vehicle outer side holding wall 41 extending from the vehicle outer side end of the bottom wall main body 46 toward the door frame 2 (upward in FIG. 1). The bottom wall body 46 includes a bottom wall vehicle inner holding wall 42 extending from the vehicle inner side end of the bottom wall body 46 in the direction of the door frame 2 (upward in FIG. 1).

  For this reason, the bottom wall car outer holding wall 41 and the bottom wall car inner holding wall 42 are provided between the bottom wall body 46 and the panel tip 2h formed horizontally at the tip of the upper side of the door frame 2 which is the channel 3. A sufficient space can be provided, and the bottom wall body 46 does not collide with the door frame 2 even if the door glass 5 rises and abuts against the bottom wall body 46 to push up the bottom wall body 46.

  The bottom wall vehicle outer side holding wall 41 is formed from the vehicle outer side end of the bottom wall main body 46 to the outside of the bottom wall main body 46 and obliquely toward the center in the width direction (oblique left upper direction in FIG. 1). For this reason, even if the door glass 5 rises and the front end of the door glass 5 comes into contact with the bottom wall main body 46, the bottom wall vehicle outer side holding wall 41 bends in the direction of the vehicle outer side wall 20, It is possible to prevent the vehicle outer side wall 40 from collapsing by pressing the part, and to prevent the generation of a gap between the vehicle outer side wall 20 and the door frame 2 or the door molding 50, thereby improving sound insulation. .

  The bottom wall vehicle outer side holding wall 41 has a bottom wall projection 45 extending at a portion connected to the vehicle outer side connection portion 26 in an oblique central direction in the width direction of the bottom wall main body 46 (oblique left upper direction in FIG. 1). May be. In this case, the bottom wall protrusion 45 abuts against the panel front end 2h of the door frame 2, and the vehicle outer side connecting portion 26 pulls the front end of the vehicle outer side wall 20 so that the vehicle outer side wall 20 falls to the vehicle outer side. The vehicle outer side wall 20 does not fall down toward the inside of the glass run body 16. Therefore, there is no gap between the door frame 2 or door molding 50 and the vehicle outer side wall 20, and sound insulation can be improved.

  The bottom wall vehicle outer side retaining wall 41 is provided with a bottom wall vehicle outer side seal lip 43 at a portion connected to the vehicle outer side connecting portion 26 toward a diagonally outward direction in the width direction of the bottom wall main body 46 (in the diagonally upper right direction in FIG. 1). It may be extended. In this case, the sealing performance between the panel front end 2h of the door frame 2 and the bottom wall 40 can be improved, and the sound insulation is improved.

  In addition, the bottom wall vehicle outer side holding wall 41 is formed to be bent in a cross-sectional shape from the vehicle outer side end of the bottom wall main body 46 like a bottom wall vehicle inner side holding wall 42 described later. The portions are a bottom wall vehicle outer side first inclined wall formed outwardly of the bottom wall body 46 and obliquely in an outer direction in the width direction (diagonally upper right direction in FIG. 1), and a bottom wall vehicle outer side first inclined wall. The top end portion may form a bottom wall vehicle outer side second inclined wall formed obliquely in the center direction of the bottom wall body 46 in the width direction (obliquely upper left direction in FIG. 1). In this case, the same oil effect as the bottom wall vehicle inner side retaining wall 42 described later can be obtained.

  The bottom wall vehicle inner side holding wall 42 is formed by bending in a cross-sectional shape from the vehicle inner side end of the bottom wall main body 46, and the portion on the bottom wall main body 46 side is outside the bottom wall main body 46 and in the width direction. The bottom wall vehicle inner side first inclined wall 47 formed obliquely in the outer direction (slant upper left direction in FIG. 1), and the tip portion from the bottom wall vehicle inner first inclined wall 47 is in the width direction of the bottom wall body 46. It is formed from the bottom wall vehicle inner side second inclined wall 49 formed obliquely in the center direction (oblique upper right direction in FIG. 1).

  When the door glass 5 rises and the front end of the door glass 5 comes into contact with the bottom wall main body 46, the vehicle interior first inclined wall 47 presses the vehicle interior side wall 30 and the vehicle interior side wall 30 falls. It is possible to prevent the occurrence of a gap between the vehicle interior side wall 30 and the door frame 2 and improve the sound insulation.

Furthermore, since the vehicle interior first inclined wall 47 and the bottom wall interior second inclined wall 49 are formed to be bent in a cross-sectional shape, even if the front end of the door glass 5 abuts against the bottom wall body 46, the bottom The wall-car inner side retaining wall 42 can absorb the impact at the portion bent in a square cross section and prevent the car inner side wall 30 from falling down.
The tip of the bottom wall vehicle inner side second inclined wall 49 of the bottom wall vehicle inner holding wall 42 is connected to the vehicle inner side connection part 36. For this reason, even if the door glass 5 comes into contact with the bottom wall main body 46 and the bottom wall main body 46 is deformed, the vehicle inner side coupling portion 36 absorbs the deformation and the vehicle inner side wall 30 is hardly deformed.

  Further, the bottom wall vehicle inner holding wall 42 has a bottom wall vehicle inner inclined surface 48 formed in a sloped shape on the surface of the first bottom wall vehicle inner first inclined wall 47 facing the vehicle inner side wall 30. A sloped vehicle-inside side wall inclined surface 37 is also formed at the base portion of the vehicle-inside side wall 30 so as to face the bottom wall vehicle-inside first inclined wall 47. When the glass run 10 is attached to the door frame 2, the bottom wall vehicle inner side first inclined surface 48 and the vehicle inner side wall inclined surface 37 abut.
