With these configurations, the vertical sash portion 220 has substantially the same cross-sectional shape as that of the vertical sash portion 220, and has a T-shaped configuration as a whole. The garnish 1 is attached to the horizontal portion which is a part of the T-shape, that is, the flange portion 21 via the joining means 3.

  Next, the garnish 1 attached to the surface side of the vertical sash portion 220 and the roof side sash portion 210 will be described. The garnish 1 is mainly formed of a thermoplastic material, and is integrally formed to have substantially the same planar shape as the sash assembly 2 by injection molding means or the like. (See FIG. 1). In addition to the garnish 1 formed so as to have substantially the same planar shape as the sash assembly 2 as shown in FIG. 1, for example, only the vertical sash part 220 in FIG. 1 or the roof side sash part 210. It is also conceivable to have a planar form that only covers the surface. And the garnish 1 which consists of such a structure forms the center part of the width direction, Comprising: The part 11 which exists so that it may oppose the flange part 21 at the time of mounting | wearing is shown, for example in FIG. 2 or FIG. Thus, it has a predetermined thickness (T). Moreover, while having such a structure, the terminal portion 15 of the garnish 1 is wound around the side end portion 211 of the flange portion 21, that is, the side end portions of the groove portion 26 and the retainer portion 28. And it has a thin value (t). That is, the thickness of the present garnish 1 satisfies the relational expression of T> t, and the value of T is about 2 mm in the present embodiment. It is. Such a garnish 1 is attached to the flange portion 21 of the sash assembly 2 via the joining means 3 as shown in FIGS. Examples of the bonding means 3 include bonding means such as a double-sided adhesive tape.

It is also conceivable to entrain to the back side of 21. In order to wind the garnish 1 on the back side as described above, first, the terminal portion 15 of the garnish 1 is formed slightly longer as shown in the two-dot chain line in FIG. Means) It is joined to the flange portion 21 via 3. In such a state, the end portion 15 that is upright as shown by the two-dot chain line in FIG. 4 is brought into close contact with the back surface side of the flange portion 21 using, for example, predetermined heat caulking means. I will let you. In this way, by attaching the terminal portion 15 of the garnish 1 to the back surface side of the side end portion 211 of the flange portion 21, the attachment property to the flange portion 21 of the garnish 1 is improved (improved), and as a door frame Will also improve the appearance.

  In many cases, the garnish 1 has a single-layer structure, but in some cases, a garnish having a two-layer structure as shown in FIG. 5 may be used. That is, the garnish 1 is provided on the back surface side of the surface resin sheet portion X and the surface resin sheet portion X formed of an acrylic resin or the like whose surface is hard to be scratched, and has excellent moldability. And it consists of a two-layer structure with a backside resin sheet portion Y made of inexpensive polyethylene (PE), polypropylene (PP) or the like. Moreover, the surface resin sheet part X is formed with a transparent body or a semi-transparent body, and the garnish 1 excellent in design property can be obtained by providing a predetermined pattern etc. in the back surface resin sheet part Y side. become. Further, the surface resin sheet portion X is formed of a transparent body or a semi-transparent body, and a patterned intermediate layer or pattern layer is provided between the surface resin sheet portion X and the back surface resin sheet portion Y. By using, for example, a metal foil as the intermediate layer or pattern layer, it becomes possible to obtain the garnish 1 having a metallic color and excellent in design.

  The operation and effect of the vehicle door frame having the garnish 1 having such a configuration will be described. That is, in the present embodiment, the sash assembly 2 having a T-shaped constant cross-sectional shape is joined to the flange portion 21 of the garnish 1 made of a plastic molded product. Therefore, the manufacturing cost of the entire vehicle door frame can be reduced. Further, the garnish 1 itself does not have a boss portion or the like as in the prior art, and is therefore formed with a relatively smooth surface, so it is integrally formed using an injection molding means or the like. Even in this case, there is no need to worry about the occurrence of “sink marks” on the surface. Therefore, the garnish 1 with excellent appearance can be manufactured at low cost. Such a garnish 1 is attached to the surface of the sash assembly 2 with a joining means 3 such as a double-sided adhesive tape or adhesive, or the terminal portion 15 of the garnish 1 is previously shown as shown by the solid line in FIG. Prepare a curled one and engage it with the side end 211 of the flange portion 21 of the door sash, that is, fit the side end 211 and the terminal portion 15 formed in a curl shape. By doing so, a vehicle door frame can be formed. As a result, it is possible to inexpensively provide (manufacture) a vehicular door frame that has a sense of unity between the roof portion and the B pillar and that is excellent in appearance. Further, as shown in FIGS. 2 to 4, the terminal portion 15 of the garnish 1 is formed thin and the tip portion is wound around the side end portion 211 side of the flange portion 21. Reduction of wind noise (wind noise) as a whole can be achieved.

  Next, a modification in which the side visor portion 5 as shown in FIGS. 6 and 7 is integrally provided in a part of the garnish having such a configuration will be described. This is also not different from the basic structure of the garnish 1 in the vehicle door frame described in the above embodiment. In other words, the modification is formed at a roof portion 111 formed along the roof side opening of the garnish 1 so as to be parallel to the roof portion 111 and to have a predetermined width. The side visor portion 5 is integrally provided. Such a side visor portion 5 is formed integrally with the garnish body at the roof portion 111 of the garnish 1 by vacuum forming means or injection forming means. Therefore, compared to the case where a side visor as a separate part is retrofitted from the front side of the garnish, it is possible to reduce the number of mounting steps and reduce the manufacturing cost by reducing the number of parts. It becomes possible to plan. Further, when the side visor portion is retrofitted with a double-sided tape or the like at the flange portion 21 of the door sash, for example, as in the conventional one, the portion of the double-sided tape can be seen from the outside, and the design is deteriorated. It is possible to avoid such things.
