Description

  The present invention relates to a frame molding mounted on a window frame of a vehicle door.

  As a door molding to be mounted on the window frame of the vehicle door, for example, as described in Patent Document 1, there is one configured by a door upper frame molding, a door rear frame molding, and a door lower belt molding. The door upper frame molding and the door rear frame molding are connected by a connecting portion, and the door rear frame molding and the door lower belt molding are connected by a connecting portion. The door upper frame molding and the door lower belt molding have a large radius of curvature and are configured with a substantially uniform curvature. On the other hand, the door rear frame molding is greatly curved along the rear part of the window frame.

  As a door lower belt molding, there is one having a structure described in Patent Document 2, for example. The door lower belt molding includes a decorative member and a resin holder. The resin holder has a constant cross section in the longitudinal direction as a cross section orthogonal to the longitudinal direction of the lower part of the window frame. Therefore, the resin holder can be formed by an extrusion molding method.

  Since the door rear frame molding is provided with an acute curved portion, the decorative member molded by pressing or the like and the resin holder molded by injection molding or the like are joined with an adhesive or the like. It is configured.

  By the way, it is conceivable to apply the structure described in Patent Document 2 also to the lower part of the door rear frame molding connected to the door lower belt molding. In this case, the lower part of the door rear frame molding has a structure including a decorative member 51 and a resin holder 53 as shown in FIG. The decorative member 51 has a bent portion 52 that is bent toward the vehicle inner side at an end portion (lower end portion) of the vehicle door D on the door body DB side. The resin holder 53 includes a hard resin-made hard portion 54 that covers the decorative member 51 from the outside of the vehicle, and a soft resin-made soft portion 55 that is joined to the hard portion 54. The soft portion 55 has a lip portion 56 that is located closer to the door body DB (lower side) than the decorative member 51 and that extends while curving toward the vehicle inner side. The lip portion 56 abuts on the door body DB and reduces the gap with the door body DB to improve the appearance. Further, when the lip 56 is brought into contact with the door body DB when the door rear frame molding 50 is attached to the lower part of the window frame, the decorative member 51 side of the lip 56 as shown by an arrow Y in FIG. The power to go to is added. However, since the lip portion 56 is curved in advance toward the inside of the vehicle, the lip portion 56 slightly bends toward the decorative member 51 as indicated by a two-dot chain line, but is unlikely to be reversed.

JP 2010-70106 A JP 2009-196391 A

  However, when the lip portion 56 abuts against the door body DB when the door rear frame molding 50 is attached to the rear portion of the window frame, the soft portion 55 is placed on the portion 57 below the bent portion 52. A force in the direction of approaching the DB is applied. By this force, the portion 57 is bent so as to rotate in the direction indicated by the arrow X (inward and downward) with the boundary portion 58 with the upper portion as a fulcrum. Due to this bending, the gap G between the portion 57 of the soft portion 55 and the bent portion 52 of the decorative member 51 is increased, and the appearance is lowered. The gap G is generated because the lip portion 56 is provided in the resin holder 53 and the resin holder 53 is bonded to the decorative member 51.

  The present invention has been made in view of such circumstances, and its purpose is to suppress a decrease in appearance due to an increase in the gap between the decorative member and the soft portion when mounted on a window frame. It is to provide a frame molding that can do.

In order to achieve the above object, the invention according to claim 1 and claim 3 includes a decorative member and a resin holder joined to the decorative member and separate from the decorative member. A frame molding that is attached to a window frame on the upper side of the door body of the door and has a curved portion, wherein the resin holder includes a hard portion made of hard resin that covers the decorative member from the outside of the vehicle, and the decorative member. And a soft resin-made soft portion that is disposed on the door body side and is joined to the hard portion, and the soft portion has a lip portion that extends toward the inside of the vehicle and contacts the door body. At least a part of the end of the hard part on the door body side wraps around the door body side of the decorative member from the vehicle inner side and extends to the vehicle outer side. The soft part is located outside the inner end surface of the vehicle. Together is one of the hard portion and the soft portion has a recess that opens toward the other as part of the joint and the other, joining the protruding portion formed in a state of being filled in the recess As part of the part.

  According to the above configuration, when the lip portion comes into contact with the door body when the frame molding is attached to the window frame, the resin holder has a portion closer to the door body than the end of the decorative member on the door body side. A force is applied in a direction to bring this closer to the door body. However, in the first aspect of the present invention, at least a part of the end portion of the hard portion on the door body side extends from the vehicle inner side toward the vehicle outer side with respect to the end portion of the decorative member. And since the hard part is joined to the soft part on the vehicle outer side rather than the inner end surface of the end part on the door body side of the decorative member, the door body is closer to the door body than the end part of the decorative member on the door body side. The side portion is not easily deformed even when the above-described force is applied. As a result, it is difficult for the resin holder to have a larger gap between the door body side portion of the decorative member and the decorative member than the door body side end of the decorative member.

  According to said structure, a part of junction part of the hard part in a resin holder and a soft part is comprised by the junction part of the protrusion formed in the state with which the recessed part was filled with the recessed part. The area of the joint surface at this time is larger by the area where the recess and the protrusion are joined than when the hard part and the soft part are joined together in a plane. The joint strength between the hard part and the soft part increases as the joint surface becomes wider.

Further, in the invention according to claim 1, wherein the recess is the provided on the end portion of the door body side of the rigid portion, and opened toward the soft portion located in the vehicle outer side of the Dotan portion And the said recessed part has a pair of opposing wall surface which a space | interval expands toward the vehicle interior side .

  According to the above configuration, the pair of opposing wall surfaces of the concave portion provided in the hard portion is narrower toward the vehicle outer side, and when the lip portion contacts the door body, the protrusion on the lip portion side is the concave portion. Against movement outside the vehicle. For this reason, the bonding strength of the soft part to the hard part increases, and the soft part is less likely to be peeled from the hard part to the vehicle outer side.

Further, in the invention described in claim 3, wherein the recess is open the provided on the end portion of the door body side of the rigid portion, and toward the lip portion located below the Dotan portion The concave portion has a pair of opposing wall surfaces whose intervals are narrowed toward the lower side .
The invention according to claim 2 is the lip according to claim 1, wherein the recess is provided at an end of the hard portion on the door body side and located below the end. The concave portion has a pair of opposing wall surfaces whose intervals are narrowed toward the lower side.

  According to said structure, a pair of opposing wall surface of the recessed part provided in the hard part has a space | interval narrowing so that the lower side, and when a lip part contact | abuts with a door body, the protrusion part by the side of a lip part is a recessed part. To move downward. For this reason, the bonding strength of the soft part to the hard part increases, and the soft part is less likely to be peeled downward from the hard part.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, a clip for attaching the resin holder to the vehicle door is integrally formed on the hard portion. It is a summary.

  According to said structure, at the time of shaping | molding a hard part, a clip will be shape | molded in the form integrated with the hard part, and while the number of parts of a frame molding reduces, the operation | work which attaches a clip becomes unnecessary.

  According to the frame molding of the present invention, it is possible to suppress a decrease in appearance due to an increase in the gap between the decorative member and the soft portion when the frame molding is attached to the window frame.

The door rear frame molding 13 and the door lower belt molding 12 are connected to the rear end of the door lower belt molding 12 by inserting a connecting bracket 25 described later at the front end of the horizontal portion 14. Yes.

  The horizontal portion 14 includes a decorative member 16 formed of a hard plate material, and a resin holder 20 joined to the decorative member 16 and separate from the decorative member 16. As a hard board | plate material which comprises the decoration member 16, metal plates, such as stainless steel, aluminum, iron, are used, for example. The decorative member 16 is formed by pressing these hard plate materials.

  As shown in at least one of FIGS. 4A and 4B, the main part of the decorative member 16 includes a main body part 17 that is bent so as to protrude obliquely upward on the outer side of the vehicle, and the main body part 17. It is comprised by the bending part 18 formed by bending a lower end part to a vehicle inner side. The bent portion 18 constitutes an end of the decorative member 16 on the door body DB side. In the upper end portion of the main body portion 17, caulking pieces 19 are provided at a plurality of locations in the longitudinal direction (front-rear direction of the vehicle) of the decorative member 16. Each caulking piece 19 is bent downward from the upper end portion of the main body portion 17. In FIG. 3, each caulking piece 19 is shown in a state before being bent. The decorative member 16 is locked to the resin holder 20 by a bent portion 18 and a caulking piece 19.

  As shown in at least one of FIGS. 4A, 4 </ b> B, and 5, the resin holder 20 includes a hard portion 21 formed of a hard resin and a soft portion 26 joined to the hard portion 21. Become. In FIG. 5, illustration of the soft portion 26 is omitted.

  The main portion of the hard portion 21 is configured by a shape corresponding to the main body portion 17 of the decorative member 16, that is, a main body portion 22 that is bent so as to protrude obliquely upward on the outside of the vehicle. The main body 22 is covered with the decorative member 16 from the outside of the vehicle. The main body portion 17 of the decorative member 16 is attached to the main body portion 22 of the hard portion 21 with a double-sided adhesive tape 29. In addition to the main body portion 22, the hard portion 21 includes an extending portion 23 that wraps around the bent portion 18 of the decorative member 16 from the vehicle inner side, passes directly below the bent portion 18, and extends to the vehicle outer side. The extending portion 23 constitutes an end portion on the door body DB side of the hard portion 21, and the extending end surface 23 a is located on the vehicle outer side than the inner end surface 18 a of the bent portion 18.

  In the hard portion 21, clips 24 for attaching the resin holder 20 to the vehicle door D are integrally formed at a plurality of locations in the length direction of the horizontal portion 14 (the longitudinal direction of the vehicle). Each clip 24 hangs downward from the upper end portion of the main body portion 22 in the hard portion 21. Further, a connecting bracket 25 is integrally formed at the front end portion of the hard portion 21 and is fitted into the rear end portion of the door lower belt molding 12 shown in FIG. Here, the hard part 21 and the connecting bracket 25 are required to have (i) a small amount of deformation in the longitudinal direction (vehicle longitudinal direction) due to heat (hard to expand and contract) and (ii) high rigidity. On the other hand, the clip 24 is required to bend to some extent (iii). Therefore, when the hard portion 21, the clip 24, and the connecting bracket 25 are integrally formed, a resin material that satisfies these conditions is used. In this embodiment, for example, polypropylene (Mitsubishi Chemical Corporation: trade name “QP516B”) containing about 40% talc (inorganic powder obtained by finely pulverizing ore called talc) is used as such a resin material. .

  The soft part 26 is arranged on the vehicle outer side of the extension part 23, and is constituted by a base part 27 joined to the extension part 23 and a lip part 28 formed on the lower side of the base part 27. . Many of the joint surfaces of the hard part 21 and the soft part 26 are constituted by the extended end face 23 a of the extended part 23. Many of the joint surfaces of the soft portion 26 and the hard portion 21 are constituted by a surface 27 a on the vehicle inner side of the base portion 27.

  As shown in FIG. 8, the main function of the lip portion 28 is to fill a gap between the decorative member 16 and the door body DB to improve the appearance or to suppress the generation of wind noise. . Further, as another function of the lip portion 28, the metal decorative member 16 may be prevented from coming into direct contact with the door body DB and being damaged. The lip portion 28 is curved so as to swell obliquely downward on the outer side of the vehicle, and the lower portion is located on the inner side of the vehicle. The lip portion 28 gradually decreases in thickness as it moves downward from the base portion 27 (closer to the door body DB), and is configured to come into contact with the door body DB at the lower end thereof. The cross-sectional shape of the soft portion 26 having the lip portion 28 having such a shape is substantially L-shaped. The soft part 26 is formed of a softer resin material than the hard part 21. In this embodiment, olefin elastomer (TPO) is used as such a resin material, but is not limited to this.

  Furthermore, in this embodiment, as shown in at least one of FIGS. 4A, 4B, and 5, a structure that increases the bonding area between the hard portion 21 and the soft portion 26 is employed. At a plurality of locations in the longitudinal direction of the extending portion 23 (the vehicle front-rear direction), concave portions 31 that open toward the vehicle outer side are provided as part of the joint portion of the hard portion 21 with the soft portion 26. . Each concave portion 31 penetrates the extending portion 23 in the vertical direction, and opens toward the lip portion 28 located below the extending portion 23. Here, a portion opened in the extended end surface 23a of the extended portion 23 is referred to as an “opening portion 32”. Further, at a plurality of locations in the longitudinal direction (front-rear direction of the vehicle) of the base portion 27 in the soft portion 26, protrusions 36 formed in a state of being filled in the concave portion 31 are connected to the hard portion 21 in the soft portion 26. Provided as part of the joint.

  Further, in the present embodiment, a structure that increases the coupling strength at the recess 31 and the protrusion 36 is employed. As shown in at least one of FIGS. 6 and 7A, 7B, a pair of opposing wall surfaces 34, 35 facing each other in the longitudinal direction of the extension 23 (the longitudinal direction of the vehicle) in each recess 31. Are inclined with respect to the inside and outside of the vehicle so that the distance between them increases toward the inside of the vehicle. In the present embodiment, the opposing wall surfaces 34 and 35 are inclined at the same gradient with respect to the inner and outer directions of the vehicle. In addition, the opposing wall surfaces 34 and 35 are inclined with respect to the vertical direction of the vehicle so that the interval between them becomes narrower toward the lower side. In the present embodiment, the opposing wall surfaces 34 and 35 are inclined at the same gradient with respect to the vertical direction of the vehicle.

  Here, the distance between the opposing wall surfaces 34 and 35 at the upper end of the opening 32 is Ta. In the recess 31, the distance between the opposing wall surfaces 34, 35 at the upper end of the portion farthest from the opening 32 toward the vehicle interior is defined as Tb. The interval between the opposing wall surfaces 34 and 35 at the lower end of the opening 32 is Tc. By inclining the opposing wall surfaces 34 and 35 as described above, a relationship of Tc <Ta <Tb is established between the intervals Ta, Tb, and Tc.

  The protrusion 36 formed in a state of being filled in the recess 31 has the same outer shape as the inner surface of the recess 31. That is, the protrusion 36 has an outer shape in which the width in the longitudinal direction (vehicle longitudinal direction) of the base portion 27 increases toward the vehicle inner side and decreases toward the lower side.

  The resin holder 20 having the above configuration is formed by a two-color injection molding method. In this molding method, first, the hard portion 21 in which the main body portion 22, the extending portion 23 having the concave portion 31, the clip 24, and the connecting bracket 25 are integrated is molded in a mold. Thereafter, in the same mold as described above, the base portion 27 and the lip portion 28 having the protrusions 36 are joined to the extension portion 23 at the base portion 27, and the soft portion 26 integrated with the hard portion 21 is formed. Molded.

The horizontal portion 14 of the door rear frame molding 13 is configured as described above. Next, the operation of the horizontal portion 14 will be described.
In the resin holder 20, as shown in FIG. 4A, the hard part 21 and the soft part 26 are joined. Most of the joints are the extended end surface 23a of the extended portion 23 in the hard portion 21 (where the opening 32 is not provided) and the inner surface 27a of the base portion 27 of the soft portion 26 (however, And a portion where the protrusion 36 is not provided). Further, as shown in at least one of FIG. 3, FIG. 4B and FIG. 5, a part of the bonding is between each of the plurality of recesses 31 and the protrusion 36 formed in each recess 31. Is done. The area of the joint surface at this time is such that when the hard part 21 and the soft part 26 are joined in a plane, that is, when the recess 31 and the protrusion 36 are not provided, the extension end face 23a of the extension part 23 is provided. Compared with the case where the inner surface 27a of the base portion 27 is joined, the area where the concave portion 31 and the projection 36 are joined becomes wider. The joint strength between the hard part 21 and the soft part 26 increases as the joint surface becomes wider.

  Further, as shown in at least one of FIGS. 6 and 7A, 7B, the pair of opposing wall surfaces 34, 35 of the recess 31 provided in the extending portion 23 of the hard portion 21 are located closer to the vehicle exterior side. That is, the distances Ta and Tb are narrowed toward the opening 32, and when the lip portion 28 comes into contact with the door body DB, the protrusion 36 on the lip portion 28 side moves to the outside of the vehicle with respect to the recess 31. To regulate. Therefore, the bonding strength of the soft part 26 to the hard part 21 is increased.

  Further, the intervals Ta and Tc are narrower toward the lower side of the opposing wall surfaces 34 and 35, and when the lip portion 28 comes into contact with the door body DB, the protruding portion 36 on the lip portion 28 side is opposed to the recess 31. Restrict movement to the lower side. Therefore, the bonding strength of the soft part 26 to the hard part 21 is increased.

  By the way, as shown in FIG. 8, when the lip portion 28 comes into contact with the door body DB when the door rear frame molding 13 (horizontal portion 14) is attached to the lower portion of the window frame WF, A force in a direction in which the bent portion 18 is closer to the door body DB is applied to the door body DB side (lower side) than the bent portion 18.

  However, in the present embodiment, the extended portion 23 of the hard portion 21 wraps around the bent portion 18 from the vehicle inner side, passes directly below the bent portion 18 and extends toward the vehicle outer side. Many of 23 are joined to the soft part 26 on the vehicle outer side than the inner end face 18a of the bent part 18. A portion of the resin holder 20 closer to the door body DB than the bent portion 18 is constituted by the extending portion 23 and the soft portion 26. The extension part 23 is a part of the hard part 21 and has higher rigidity than the soft part 26. Therefore, even if the above-mentioned force is applied to the extending portion 23, that is, the resin holder 20, the above-described force is applied to the door body DB side portion of the decorative member 16 on the door body DB side end portion. 23 is less likely to be bent so as to rotate in the direction indicated by the arrow X (substantially downward) with a boundary portion 37 with the upper portion as a fulcrum. As a result, the gap G between the portion below the bent portion 18 and the decorative member 16 in the resin holder 20 is unlikely to increase.

  Further, when the lip portion 28 comes into contact with the door body DB as described above when the door rear frame molding 13 (horizontal portion 14) is attached to the lower portion of the window frame WF, the lower end portion of the lip portion 28 in FIG. As indicated by the arrow Y, a force toward the decorative member 16 is applied. At this time, for example, as shown in FIG. 9A, the soft portion 42 formed at the lower end portion of the hard portion 41 wraps around the bent portion 44 at the lower end of the decorative member 43 from the vehicle inner side to the vehicle outer side. If it extends, the lower end of the soft part 42 may be inverted as shown in FIG. 9B by the force in the direction indicated by the arrow Y.

  In this regard, in the present embodiment, the lip portion 28 is curved in advance toward the vehicle interior side. From this, the lower end portion of the lip portion 28 is bent upward as shown by a two-dot chain line in FIG.

According to the embodiment described in detail above, the following effects can be obtained.
(1) In the present embodiment, at least a part of the extending portion 23 constituting the end of the rigid body 21 on the door body DB side is replaced with the bent portion 18 constituting the end of the decorative member 16 on the door body DB side. On the other hand, it extends from the vehicle inner side to the vehicle outer side, and is joined to the soft portion 26 on the vehicle outer side than the inner end surface 18a of the bent portion 18 (FIG. 8).

  Therefore, when the lip portion 28 comes into contact with the door body DB when the door rear frame molding 13 (horizontal portion 14) is attached to the window frame WF, the door body DB is located closer to the door body DB than the bent portion 18 of the resin holder 20. On the other hand, even if a force is applied in a direction to bring the door body DB closer to the door body DB, the same portion can be made difficult to deform. It is possible to prevent the appearance from the outside of the vehicle from deteriorating due to the gap G between the portion (soft portion 26) below the bent portion 18 of the resin holder 20 and the decorative member 16 becoming large.

  (2) In the present embodiment, the extension portion 23 of the hard portion 21 is provided with a concave portion 31 that opens toward the base portion 27 of the soft portion 26 (toward the vehicle outer side). In addition, the base 27 is provided with a protrusion 36 filled in the recess 31 as a part of the joint with the hard portion 21 (FIGS. 6, 7A and 7B). )).

Therefore, the area of the joining surface of the hard part 21 and the soft part 26 can be widened by these recessed part 31 and the protrusion part 36, and joining strength can be raised.
(3) In the present embodiment, in the concave portion 31, the opposing wall surfaces 34 and 35 facing each other in the longitudinal direction of the horizontal portion 14 (the longitudinal direction of the vehicle) are such that the distances Ta and Tb between them increase toward the vehicle interior side. The vehicle is inclined with respect to the inside / outside direction of the vehicle (FIGS. 6 and 7B).

Therefore, the bonding strength of the soft part 26 to the hard part 21 can be increased, and the soft part 26 can be prevented from being peeled from the hard part 21 to the vehicle outer side.
(4) In the present embodiment, the opposing wall surfaces 34 and 35 in (3) above are inclined with respect to the vertical direction of the vehicle so that the distances Ta and Tc between them become narrower toward the lower side (FIG. 6). FIG. 7 (a)).

Therefore, the bonding strength of the soft part 26 to the hard part 21 can be increased, and the soft part 26 can be prevented from peeling off from the hard part 21 downward.
(5) In this embodiment, the clip 24 for attaching the resin holder 20 to the vehicle door D is integrally formed on the hard portion 21 (FIGS. 3 and 5).

  Therefore, when the resin holder 20 is molded, the hard portion 21 in which the clip 24 is integrated can be molded. The number of parts of the horizontal portion 14 in the door rear frame molding 13 can be reduced. Further, the work of attaching the clip 24 later becomes unnecessary, and the number of manufacturing steps can be reduced. From these things, the cost of the door rear frame molding 13 can be reduced.

  (6) Although related to the above (5), in this embodiment, the hard part 21 with the clip 24 is a resin material (polypropylene containing about 40% talc) that is hard to expand and contract and has high rigidity but is bent to some extent. ).

  Therefore, it can suppress that the main-body part 22 expands / contracts to a longitudinal direction with a heat | fever, and appearance falls. Moreover, the clip 24 can be elastically deformed when attached to the vehicle door D.

(7) In addition to the above (5), in this embodiment, a connecting bracket 25 for coupling with the door lower belt molding 12 is integrally formed on the hard portion 21 (FIGS. 3 and 5).
For this reason, the hard part 21 for attaching the door rear frame molding 13 to the window frame WF has other functions (the function of attaching the resin holder 20 to the vehicle door D and the rear end of the door lower belt molding 12. Functions to be linked to each other).

  (8) As a configuration different from the present embodiment of the door rear frame molding, the soft portion is decorated without the hard portion so that the hard portion is omitted and the bent portion of the decorative member is covered with the soft portion from the vehicle inner side. What is directly joined to a member is also considered. When manufacturing the door rear frame molding having this configuration, many steps (I) to (IV) described below are required.

(I) The process of apply | coating an adhesive agent to the lower end part of a decoration member.
(II) A process of putting the decorative member in a drying furnace and baking the adhesive on the decorative member.
(III) A step of arranging a decorative member as an insert member in a mold and injecting a soft resin into the mold to mold a soft portion.

(IV) A step of cutting off the burrs at the part between the decorative member and the soft part.
In this respect, in this embodiment, the resin holder 20 composed of the hard portion 21 and the soft portion 26 is molded by two-color injection molding method, and then the decorative member 16 is pasted on the resin holder 20 by the double-sided adhesive tape 29. The door rear frame molding 13 (horizontal portion 14) is manufactured by wearing.

Therefore, prior to the molding of the soft portion 26, a process of applying an adhesive to the decorative member 16 and a process of baking the adhesive are not required.
Further, in the present embodiment, a configuration in which the bent portion 18 of the decorative member 16 is covered with the soft portion 26 from the vehicle inner side is not adopted. Therefore, a parting part that can be seen from the outside of the vehicle cannot be formed between the decorative member 16 and the soft part 26, and a step for removing burrs becomes unnecessary.

In the present embodiment, a step of forming the hard portion 21 is required. However, since the hard portion 21 is formed together when the soft portion 26 is formed, it does not directly increase the number of steps.
Thus, in this embodiment, a manufacturing process can be decreased and the cost of the door rear frame molding 13 can be reduced.

Note that the present invention can be embodied in another embodiment described below.
<About the decorative member 16>
The decoration member 16 may be formed using a mold such as a mold instead of the press work.

<About the extension part 23 of the hard part 21>
The position of the extended end surface 23a of the extended portion 23, that is, the extent of extension of the extended portion 23, within a range that satisfies the condition that “the inner side 18a of the bent portion 18 of the decorative member 16 is outside the vehicle”. May be changed.

  For example, you may extend the extension part 23 to the surface outside the vehicle of the base 27 in the said embodiment. In this case, the soft part 26 is constituted only by the lip part 28 (the base part 27 is omitted), and the upper end surface of the lip part 28 is joined to the lower surface of the extension end part of the extension part 23. If it does in this way, it will become the longest in the range which the extension part 23 can take, and the big effect which suppresses that the part below the bending part 18 of the resin holder 20 will bend to the door body DB side will be acquired. It is done.

  However, in this case, there is a possibility that a joint portion of the soft portion 26 with the hard portion 21 can be seen from the vehicle outer side. Moreover, when there is a difference in color between the hard part 21 and the soft part 26, there is a possibility that it can be seen from the outside of the vehicle. Furthermore, since the resin holder 20 is formed of a different material such as a hard resin and a soft resin, there is a risk of sink marks. In that case, the sink marks may be visible from the outside of the vehicle. If these levels are small and not so noticeable, the above change is effective in suppressing the gap G between the decorative member 16 (bending portion 18) and the resin holder 20 (soft portion 26) from expanding. is there.

  However, if the lines, color differences, sink marks, etc. of the joint portion are conspicuous, as described above, the inner surface 27a of the base portion 27 of the soft portion 26 becomes the extended end surface 23a of the extended portion 23. It is desirable to join. In this case, the length of the extending portion 23 is shortened, and the effect of suppressing the expansion of the gap G is somewhat reduced, but the problem of deterioration in appearance is unlikely to occur.

  In addition, said effect is acquired even if the thickness about the vehicle inside / outside direction of the base 27 is made thinner than the said embodiment. This thickness is desirably set in consideration of other requirements such as formation of the recess 31 and ease of molding.

<About the recessed part 31 and the protrusion 36>
-Contrary to the said embodiment, the recessed part 31 is provided in the soft part 26, and it is good also considering this as a part of junction part with the hard part 21 of the soft part 26. FIG. Further, the protrusion 36 may be provided on the hard portion 21 and this may be a part of the joint portion of the hard portion 21 with the soft portion 26.

  The slope of the pair of opposing wall surfaces 34 and 35 in the recess 31 may be different between the opposing wall surfaces 34 and 35. In an extreme case, only one of the opposing wall surfaces 34 and 35 may be an inclined surface.

-You may form a pair of opposing wall surfaces 34 and 35 in the recessed part 31 so that the space | interval Ta and Tb between them may become fixed in the inside and outside direction of a vehicle.
Similarly, the pair of opposing wall surfaces 34 and 35 in the recess 31 may be formed such that the distances Ta and Tc between them are constant in the vertical direction of the vehicle.

  The concave portion 31 and the protrusion 36 are omitted, and the soft portion 26 and the hard portion 21 are joined to each other only at the planar joining surfaces (the extending end surface 23a of the extending portion 23 and the inner surface 27a of the base portion 27). You may make it make it.

<Other matters>
The present invention is also applicable to a frame molding including the curved portion 9 in which the door rear frame molding 13 and the door lower belt molding 12 are integrally formed and cannot be processed by bending or the like. In this case, the resin holder 20 is molded separately from the decorative member 16 and assembled to the decorative member 16 as in the above embodiment.
