Description

The present invention relates to a molding attached to a vehicle and a method for assembling the molding.

A molding, which is an exterior member, is attached to the door of the vehicle for the purpose of protecting the door frame (door sash) and the edge of the door panel and improving the aesthetic appearance. For example, belt moldings, upper sash moldings, frame moldings, etc., which are attached along the inner edge of the window opening, are known.

The molding is often configured by attaching an end member to the longitudinal end of the molding body, which is a long member. As the end member, an end cap having a lid portion that covers the end portion of the molding body, a connecting member inserted between different molding bodies, and the like are known. Such an end member has an insertion portion to be inserted into the molding body, and the insertion portion is fitted to a predetermined portion of the molding body, the insertion portion is press-fitted into the molding body, or the insertion portion is inserted. By fixing it to the molding body with adhesive etc., it is held so that it will not come off from the molding body.

With the existing assembly structure and assembly method as described above, it may be difficult to stably and highly accurately assemble the end member to the molding body. In particular, when the end member includes a lid portion that covers the terminal portion in the longitudinal direction of the molding body, it is difficult to bring the lid portion of the end member into close contact with the terminal portion of the molding body without causing a gap or rattling. ..

For example, simply fitting the end member so that it does not come off from the molding body in the longitudinal direction may cause the end member to rattle in the longitudinal direction of the molding. Holding by press-fitting has a high degree of difficulty in quality control, and if the holding force by press-fitting is weak, the end member tends to fall off, and if the holding force by press-fitting is to be strengthened, the load when inserting the end member will increase. .. Fixing by gluing or the like increases the number of work processes other than inserting the end member, which requires extra labor and cost.

The present invention has been made in view of such problems, and provides a vehicle molding and an assembly method thereof, which are excellent in the ease of assembling the end member to the molding body and the stability of holding the end member in the assembled state. The purpose is to do.

Hereinafter, embodiments to which the present invention is applied will be described with reference to the drawings. The molding 1 shown in FIGS. 1 to 4 is a molding for a vehicle door mounted along the inner edge of a window opening (not shown) of a vehicle door (not shown). In the following description, the inside of the vehicle, the outside of the vehicle, the inner peripheral side, and the outer peripheral side are based on the vehicle door to which the molding 1 is attached. The direction connecting the outside of the vehicle and the inside of the vehicle, that is, the thickness direction of the vehicle door is the vehicle width direction in the mall 1, and the double-headed arrow X indicates the vehicle width direction in the drawing. The side facing the inside of the window opening is the inner peripheral side, and the side facing the outside of the window opening is the outer peripheral side. The direction connecting the inner peripheral side and the outer peripheral side is the height direction in the molding 1, and in the drawing, the height direction is indicated by the double-headed arrow Y. The longitudinal direction of the molding 1 is represented by a double-headed arrow Z in the drawing. The vehicle width direction X and the height direction Y have a substantially vertical relationship.

A terminal surface 2a substantially perpendicular to the longitudinal direction Z is formed at the end of the molding body 2, and the end cap 3 is assembled so as to cover the terminal surface 2a. Of the longitudinal direction Z of the molding 1, the side facing the terminal surface 2a is the terminal side, and the side facing the opposite side of the terminal surface 2a is the back side.

The molding body 2 has a design portion 4 located on the outside of the vehicle, and a vehicle width direction portion 5 protruding inward of the vehicle with respect to the design portion 4 and extending in the vehicle width direction X. The design portion 4 is composed of a plurality of wall portions, and includes a vehicle outer wall portion 10, an inner peripheral curved portion 11, a folded wall 12, an in-vehicle extending portion 13, an outer peripheral curved portion 14, and a holding wall 15. , And the facing wall 16.

The vehicle outer wall 10 is located on the outermost side of the design portion 4, and extends substantially in the height direction Y in a cross section (FIG. 3) substantially perpendicular to the longitudinal direction Z of the molding 1. When the molding 1 is attached to the vehicle door, the vehicle outer surface of the vehicle outer wall 10 becomes a design surface that can be visually recognized from the vehicle outer side.

The inner peripheral curved portion 11 has a U-shaped shape that is bent and folded back from the end portion on the inner peripheral side of the vehicle outer wall 10 toward the outer peripheral side. The folded wall 12 extends to the outer peripheral side following the inner peripheral curved portion 11, and is located inside the vehicle outer wall 10. The folded wall 12 is a cantilevered wall portion that is substantially parallel to the vehicle outer wall 10 and has the end portion 12a facing the outer peripheral side. A part of the vehicle outer wall 10 (near the end on the inner peripheral side) and the folded wall 12 are in a relationship of facing each other with a space in the vehicle width direction X.

The in-vehicle extension portion 13 extends substantially inward from the outer peripheral end of the vehicle outer wall 10. More specifically, the in-vehicle extension portion 13 has an inclination that increases the amount of protrusion toward the outer peripheral side as it advances toward the inside of the vehicle away from the vehicle outer wall 10. The outer peripheral curved portion 14 has a U-shaped shape that is bent and folded back from the inner end portion of the in-vehicle extending portion 13 toward the inner peripheral side. The holding wall 15 extends to the outside of the vehicle following the outer peripheral curved portion 14, and is located on the inner peripheral side of the in-vehicle extension portion 13. The extension portion 13 in the vehicle and the holding wall 15 are in a relationship of facing each other with a gap in the height direction Y. The facing wall 16 extends substantially inward from the end of the holding wall 15 on the outer side of the vehicle. More specifically, the facing wall 16 has an inclination that increases the amount of protrusion to the inside of the vehicle as it advances toward the inner peripheral side away from the holding wall 15.

An internal space S1 surrounded by a vehicle outer wall 10, an inner curved portion 11, and a folded wall 12 is formed on the inner peripheral side of the design portion 4. Further, on the outer peripheral side of the design portion 4, an internal space S2 is formed between the vehicle outer wall 10 and the facing wall 16, and an internal space S3 surrounded by the vehicle interior extending portion 13, the outer peripheral curved portion 14, and the holding wall 15 is provided. It is formed. The internal space S2 and the internal space S3 communicate with each other to form an L-shaped space. The design portion 4 has a bag-like structure in which the outer side of the vehicle is covered with the outer wall 10 of the vehicle and has internal spaces S1 to S3 at both ends in the height direction Y, and the region between the internal space S1 and the internal space S2 is a region. It is open to the inside of the car.

Following the end on the inner peripheral side of the facing wall 16, the vehicle width direction portion 5 extends toward the inside of the vehicle. The vehicle width direction portion 5 is a flat plate-shaped wall portion having a relationship substantially perpendicular to the vehicle outer wall 10. As shown in FIGS. 1 and 2, the length of the vehicle width direction portion 5 toward the inside of the vehicle is shortened in a predetermined range in the longitudinal direction Z from the terminal surface 2a of the molding body 2 toward the back side. A holding wall 17 that bends from the inner end of the vehicle width direction portion 5 and projects toward the outer peripheral side is provided except near the end of the molding body 2. That is, on the outside of the vehicle width direction portion 5, a protrusion toward the outer circumference is formed by the in-vehicle extension portion 13, the outer peripheral curved portion 14, the holding wall 15, and the facing wall 16, and the inside of the vehicle width direction portion 5 is formed. Is formed with a protrusion toward the outer peripheral side by the holding wall 17. The weather strip holding portion 18 is configured by each of the protruding portions and the vehicle width direction portion 5. A weather strip (not shown) is held by the weather strip holding portion 18. The weather strip seals between the door and the vehicle body (not shown) in a watertight state when the door is closed. The legs of the weather strip engage with the holding wall 15 and the holding wall 17 to prevent the weather strip from falling off.

A holding tab 20 is further provided near the longitudinal end of the molding body 2. The holding tab 20 is formed by forming a part of the vehicle width direction portion 5 as a cantilever-shaped protrusion extending in the longitudinal direction Z. Specifically, a notch portion 21 having a shape obtained by cutting a part of the vehicle width direction portion 5 near the design portion 4 (opposing wall 16) from the terminal surface 2a in the longitudinal direction Z over a predetermined length. The remaining portion inside the vehicle with respect to the notch 21 is the holding tab 20. The holding tab 20 extends toward the terminal side from the base end portion 20a connected to the vehicle width direction portion 5, and the tip portion on the terminal side is a free end not connected to other parts of the molding body 2. ..

The molding body 2 made of a thin plate-shaped metal material can be bent by applying an external force of a predetermined value or more. In particular, the holding tab 20 can swing in the height direction Y with the vicinity of the base end portion 20a (the end portion on the inner side in the longitudinal direction Z) as a fulcrum. Further, in the vicinity of the base end portion 20a of the holding tab 20, a mountain-shaped flexible portion 22 protruding toward the outer peripheral side is formed. The bending portion 22 can be bent so as to change its width in the longitudinal direction Z by receiving an external force. An engaging hole 23 penetrating in the height direction Y is formed on the tip end side of the bending portion 22 of the holding tab 20. In other words, the holding tab 20 is provided with a flexible portion 22 on the proximal end side of the engaging hole 23 in the longitudinal direction Z. As shown in FIG. 1, the engaging hole 23 is a substantially rectangular hole in a plan view, and a pair of hole edge portions 23a extending in the vehicle width direction X apart from the longitudinal direction Z on the inner surface of the engaging hole 23. , 23b are formed.

As shown in FIGS. 1 and 2, the end cap 3 has a lid portion 6 located so as to cover the terminal surface 2a of the molding body 2 and protrudes from the lid portion 6 (extends in the longitudinal direction Z of the molding 1). It has an insertion portion 7 to be inserted into the molding body 2. The lid portion 6 has a shape that mainly covers the portion of the design portion 4 in the terminal surface 2a of the molding main body 2. What appears in FIG. 3 is the cross-sectional shape of the insertion portion 7 in the end cap 3. The insertion portion 7 has a vehicle outer wall 30, an inner peripheral side wall 31, an outer peripheral side wall 32, an intermediate wall 33, and a vehicle inner side wall 34.

The vehicle outer wall 30 is located on the vehicle outer side, and is a height direction wall extending substantially in the height direction Y in a cross section (FIG. 3) substantially perpendicular to the longitudinal direction Z of the molding 1. The inner peripheral side wall 31 is a vehicle width direction wall extending inward from the end on the inner peripheral side of the vehicle outer wall 30. The outer peripheral side wall 32 is a vehicle width direction wall extending inward from the outer peripheral end of the vehicle outer wall 30. The outer peripheral side wall 32 extends longer toward the inside of the vehicle than the inner peripheral side wall 31. The intermediate wall 33 is a height-direction wall that bends from the inner end of the inner peripheral side wall 31 and extends toward the outer peripheral side, and the outer peripheral end of the intermediate wall 33 is the outer peripheral side wall 32 in the vehicle width direction X. It is connected to the middle position. That is, the inner peripheral side wall 31 and the outer peripheral side wall 32 extending substantially in the vehicle width direction X are connected to the vehicle outer wall 30 extending substantially in the height direction Y by the intermediate wall 33, and the tubular portion 35 is formed. It is formed. The strength of the insertion portion 7 is improved by the cylindrical portion 35 having a closed cross-sectional shape.

Of the outer peripheral side wall 32, the region on the outer side of the vehicle forming the tubular portion 35 is referred to as the vehicle outer region 32a, and the region extending inward from the tubular portion 35 is referred to as the vehicle inner region 32b. The wall thickness in the height direction Y is set to be larger in the vehicle inner region 32b than in the vehicle outer region 32a. The vehicle inner side wall 34 bends from the vehicle inner end of the vehicle inner region 32b and extends toward the inner peripheral side. The vehicle inner side wall 34 is a cantilever-shaped protrusion that is not connected to a portion other than the vehicle inner region 32b.

As shown in FIG. 3, a position restricting protrusion 36 is provided so as to project from the vicinity of the boundary between the vehicle outer wall 30 and the inner peripheral side wall 31 toward the inner peripheral side. The vehicle outer surface of the position restricting protrusion 36 is located on the vehicle outer side of the vehicle outer surface of the vehicle outer wall 30. That is, in the insertion portion 7, the position restricting protrusion 36 is the portion located on the outermost side of the vehicle. Concave corners 37 facing the inside of the vehicle and the inner circumference are formed at the boundary between the inner surface of the position-regulating protrusion 36 and the inner surface of the inner peripheral side wall 31.

The insertion portion 7 of the end cap 3 is further provided with an engaged protrusion 38. The engaged protrusion 38 is a protruding portion protruding toward the outer peripheral side from the vehicle inner region 32b of the outer peripheral side wall 32, and can be inserted into the engaging hole 23 formed in the holding tab 20 of the molding body 2. As shown in FIG. 3, the width of the engaged protrusion 38 in the vehicle width direction X is substantially the same as the width of the engaging hole 23. As shown in FIGS. 4A and 4B, the end face of the engaged protrusion 38 on the terminal side (cover portion 6 side) in the longitudinal direction Z is a cover substantially perpendicular to the longitudinal direction Z. The engaging surface 38a. Of the engaged protrusions 38, the surface on the inner side (tip side of the insertion portion 7) in the longitudinal direction Z is an inclined surface 38b that intersects each of the longitudinal direction Z and the height direction Y. More specifically, the inclined surface 38b is inclined toward the terminal side (cover portion 6 side) in the longitudinal direction Z as it protrudes from the outer peripheral side wall 32 toward the outer peripheral side. The top surface portion of the engaged protrusion 38 connecting the engaged surface 38a and the inclined surface 38b is a flat surface portion 38c extending in the longitudinal direction Z.

As shown in FIG. 4B, in the longitudinal direction Z, the length of the engaging hole 23 from the hole edge portion 23a to the hole edge portion 23b is the length of the engaged protrusion from the engaged surface 38a to the inclined surface 38b. Greater than 38 lengths.

When assembling the end cap 3 to the molding body 2, the insertion portion 7 is inserted into the molding body 2 from the terminal side to the back side in the longitudinal direction Z. When the insertion portion 7 is inserted into the molding body 2, as shown in FIG. 3, the outer peripheral side surface of the outer peripheral side wall 32 abuts on the vehicle width direction portion 5, and the inner peripheral side of the inner peripheral side wall 31 (near the corner portion 37). Face abuts on the end 12a of the folded wall 12. Then, the insertion portion 7 (the portion from the inner peripheral side wall 31 to the outer peripheral side wall 32) is sandwiched and held between the vehicle width direction portion 5 of the molding body 2 and the design portion 4 (the end portion 12a of the folded wall 12). Therefore, the position of the end cap 3 in the height direction Y is determined.

In the inserted state of the insertion portion 7, the molding body 2 is slightly bent in the height direction Y, and the force for eliminating the bending causes the molding body 2 to stably insert the insertion portion 7 in the height direction Y. It is desirable to hold. For example, when the insertion portion 7 is inserted, the interior extension portion 13 and the holding wall 15 of the design portion 4 of the molding body 2 are brought close to each other in the height direction Y (the internal space S3 is narrowed) to induce bending. The dimensional relationship between the insertion portion 7 and the molding body 2 is set in 1.

Further, when the insertion portion 7 is inserted into the molding body 2, the engaged protrusion 38 is inserted into the engaging hole 23 and the position restricting protrusion 36 is inserted into the internal space S1 as shown in FIG. 3, and the vehicle outer wall 10 is inserted. Contact with. Then, between the vehicle width direction portion 5 (inner surface of the engaging hole 23 inside the vehicle) and the design portion 4 (vehicle outer wall 10) of the molding body 2, the insertion portion 7 (position restricting protrusion from the engaged protrusion 38) is formed. The portion up to 36) is sandwiched and held, and the position of the end cap 3 in the vehicle width direction X is determined.

In the inserted state of the insertion portion 7, the molding body 2 is slightly bent in the vehicle width direction X, and the force for eliminating the bending causes the molding body 2 to stably insert the insertion portion 7 in the vehicle width direction X. It is desirable to hold. For example, when the insertion portion 7 is inserted, the outer wall 10 of the vehicle and the facing wall 16 of the design portion 4 of the molding body 2 are brought close to each other in the vehicle width direction X (the internal space S2 is narrowed) to induce bending. , Set the dimensional relationship between the insertion portion 7 and the molding body 2.

The holding tab 20 separated from the other portion of the molding body 2 in the vehicle width direction X via the notch 21 can also bend in the vehicle width direction X. The bending of the holding tab 20 in the vehicle width direction X absorbs the accuracy error in the vehicle width direction X existing between the molding body 2 and the end cap 3, and the engaged protrusion 38 is auxiliary in the vehicle width direction X. The position accuracy of the end cap 3 in the vehicle width direction X can be improved by urging the vehicle.

The end cap 3 is inserted to a position where the lid portion 6 abuts on the terminal surface 2a of the molding body 2. The molding 1 has a structure in which the end cap 3 inserted up to the position is stably positioned with high accuracy in the longitudinal direction Z.

Of the lid portion 6 of the end cap 3, the surface of the molding body 2 facing the terminal surface 2a (the surface facing the inner side in the longitudinal direction Z) is referred to as the lid side facing surface 6a. Let L1 be the distance in the longitudinal direction Z from the lid-side facing surface 6a to the engaged surface 38a (engaged portion) of the engaged projection 38. On the other hand, in the free state of the molding body 2 (a state in which deformation due to an external force does not occur), the distance from the terminal surface 2a to the hole edge portion 23a (engaging portion) on the terminal side of the engaging hole 23 is defined as L2. Here, L2 is set to have a relationship slightly larger than L1 (L1 <L2). That is, when the lid-side facing surface 6a and the terminal surface 2a are arranged at the same position in the longitudinal direction Z, the engaged surface 38a of the engaged projection 38 constituting the engaged portion on the end cap 3 side The hole edge portion 23a of the engaging hole 23 constituting the engaging portion on the molding body 2 side is slightly located on the inner side in the longitudinal direction Z.

When the insertion portion 7 of the end cap 3 is inserted from the terminal surface 2a side of the molding body 2, the inclined surface 38b of the engaged projection 38 comes into contact with the tip of the holding tab 20. Then, due to the inclined shape of the inclined surface 38b, a component force is generated from the force of inserting the insertion portion 7 in the longitudinal direction Z to the height direction Y, and the holding tab 20 is pushed up toward the outer periphery with the vicinity of the base end portion 20a as a fulcrum. (See FIG. 4 (A)). When the insertion portion 7 is further inserted into the molding body 2, the engaged projection 38 approaches the engagement hole 23 while sliding the flat surface portion 38c against the inner peripheral surface of the holding tab 20.

When the end cap 3 reaches a position where the lid-side facing surface 6a is close to the terminal surface 2a, the position of the engaged protrusion 38 in the longitudinal direction Z corresponds to the engaging hole 23, and the outer peripheral side by the engaged projection 38 The holding tab 20 released from being pushed up to the outer circumference eliminates the bending toward the outer peripheral side and returns to a position substantially parallel to the vehicle width direction portion 5. Then, as shown in FIG. 4B, the hole edge portion 23a of the engaging hole 23 is in a positional relationship facing the engaged surface 38a of the engaged projection 38, and the engaged surface is on the hole edge portion 23a. By abutting (engaging) the 38a, the movement of the end cap 3 toward the terminal side in the longitudinal direction Z is restricted. That is, the end cap 3 cannot be removed from the molding body 2 to the terminal side.

As described above, the distance (L2) from the terminal surface 2a of the molding body 2 in the free state to the hole edge portion 23a of the engaging hole 23 is the distance (L2) from the lid-side facing surface 6a of the end cap 3 to the engaged projection 38. It is slightly larger than the distance (L1) to the engaged surface 38a. As a result, in a state where the engaged surface 38a is engaged with the hole edge portion 23a as shown in FIG. 4B, a force that pulls the holding tab 20 toward the terminal side in the longitudinal direction Z is applied. This force causes the bending portion 22 of the holding tab 20 to bend in the longitudinal direction Z (to bring the chevron shape closer to flat), and the force for eliminating the bending is engaged from the hole edge portion 23a. It is transmitted to the surface 38a, and the engaged projection 38 receives a force from the holding tab 20 and is urged to the inner side in the longitudinal direction Z. That is, the holding tab 20 functions as a pulling means for applying an urging force to the back side in the longitudinal direction Z with respect to the end cap 3 due to the bending generated in the bending portion 22.

Therefore, the engagement between the engaged protrusion 38 and the engaging hole 23 restricts the insertion portion 7 from coming off to the terminal side in the longitudinal direction Z, and also from the holding tab 20 to the engaged protrusion 38. In the longitudinal direction Z, a urging force is applied to pull it toward the back side, so that the lid portion 6 comes into close contact with the terminal surface 2a of the molding body 2. As a result, the end cap 3 does not rattle in the longitudinal direction Z of the molding 1 or a gap is generated between the lid portion 6 and the molding body 2, and the end cap 3 is mounted on the molding body 2 with high accuracy. Can be realized.

In the molding 1 of the present embodiment, the engagement protrusion 38 can be engaged with the engagement hole 23 of the holding tab 20 only by inserting the end cap 3 in the longitudinal direction Z. By engaging the engaged protrusion 38 with the engaging hole 23, the position of the end cap 3 is determined with high accuracy in the longitudinal direction Z, so that the end cap 3 can be prevented from coming off or urged. There is no need to do it separately. Therefore, complicated operations and processing are not required when assembling the end cap 3, and the workability is excellent.

Further, since the structure is such that the holding tab 20 is provided on the molding body 2 side and the engaged protrusion 38 is provided on the end cap 3 side, no special parts other than the molding body 2 and the end cap 3 are required, and the number of parts is increased. Does not increase.

The holding tab 20 is a simple protrusion separated from the vehicle width direction portion 5 via the notch portion 21. Since the flexible portion 22 and the engaging hole 23 on the holding tab 20 have irregularities and penetrating shapes in the height direction Y, they can be easily manufactured by press molding in the height direction Y or the like. The engaged protrusion 38 also has a shape that can be easily manufactured with a mold structure that moves in the height direction Y when molding the end cap 3. Therefore, a structure for preventing the end cap 3 from coming off and urging the end cap 3 in the longitudinal direction Z can be easily and inexpensively obtained.

In the molding 1 of the present embodiment, when the insertion portion 7 of the end cap 3 is inserted into the molding body 2 to engage the engaging hole 23 and the engaged protrusion 38, the holding tab 20 on the molding body 2 side is raised. It is deformed in the vertical direction Y and the like (see FIG. 4 (A)). Unlike this, it is also possible to configure the end cap 3 side to be deformed when the insertion portion 7 is inserted into the molding body 2.

For example, when the inclined surface 38b of the engaged projection 38 abuts on the tip of the holding tab 20 when the end cap 3 is attached, the inclined shape of the inclined surface 38b causes a force to insert the insertion portion 7 in the longitudinal direction Z. A component force is generated from the height direction Y. The outer peripheral side wall 32 of the end cap 3 may be pushed toward the inner peripheral side by the force in the height direction Y, and the engaged projection 38 may be displaced toward the inner peripheral side. When the insertion portion 7 is further inserted into the molding body 2, the pushed state of the outer peripheral side wall 32 toward the inner peripheral side is canceled, and the engaged protrusion 38 is engaged with the engaging hole 23 (B). Become.

Further, both the holding tab 20 on the molding body 2 side and the outer peripheral side wall 32 on the end cap 3 side may be deformed when the engaging hole 23 and the engaged protrusion 38 are engaged.

Subsequently, a modified example of the molding to which the present invention is applied will be described. In each of the following modification examples, the parts common to the molding 1 of FIGS. 1 to 4 described above are indicated by the same reference numerals and the description thereof will be omitted.

5 and 6 show a molding 1A which is a first modification. In the mall 1A, the parts common to the mall 1 described above are indicated by the same reference numerals and the description thereof will be omitted.

A holding tab 40 is provided on the molding body 2 of the molding 1A. The holding tab 40 is formed as a cantilevered protrusion extending in the longitudinal direction Z by cutting out a part of the vehicle width direction portion 5. Specifically, of the periphery of the holding tab 40, both sides in the vehicle width direction X and the terminal portion side in the longitudinal direction Z are cut off as the cutout portion 42, and the remaining portion surrounded by the cutout portion 42 becomes the holding tab 40. ing. The holding tab 40 extends toward the terminal side from the base end portion 40a (the end portion on the inner side in the longitudinal direction Z) connected to the vehicle width direction portion 5, and the tip portion on the terminal side is the other than the molding body 2. It is a free end that does not connect to the part of. The holding tab 40 can swing in the height direction Y with the vicinity of the base end portion 40a as a fulcrum.

Unlike the holding tab 20 of the molding 1 described above, the tip of the holding tab 40 is located behind the terminal surface 2a of the molding body 2 in the longitudinal direction Z. A curved portion 40b that curves in a U shape toward the inner peripheral side and a folded portion 40c that extends from the curved portion 40b toward the inner side in the longitudinal direction Z are formed on the tip end side of the holding tab 40. .. The end surface of the folded-back portion 40c is an edge portion 40d facing the inner side in the longitudinal direction Z. In the free state of the molding body 2, the folded-back portion 40c projects toward the inner peripheral side of the vehicle width direction portion 5.

An engaged recess 41 is formed in the end cap 3 of the molding 1A. The engaged recess 41 is a bottomed recess formed in the outer peripheral side wall 32 of the insertion portion 7 and opens toward the outer peripheral side. The engaged recess 41 is substantially rectangular in a plan view, and the inner surface of the engaged recess 41 on the inner surface side in the longitudinal direction Z (the tip end side of the insertion portion 7) is substantially perpendicular to the longitudinal direction Z. The engaged surface 41a.

Let L3 be the distance in the longitudinal direction Z from the lid-side facing surface 6a of the end cap 3 to the engaged surface 41a (engaged portion) of the engaged recess 41. On the other hand, in the free state of the molding body 2 (a state in which deformation due to an external force does not occur), the distance from the terminal surface 2a to the edge portion 40d (engaging portion) of the holding tab 40 is L4. Here, L4 is set to have a relationship slightly larger than L3 (L3 <L4). That is, when the lid-side facing surface 6a and the terminal surface 2a are arranged at the same position in the longitudinal direction Z, the engaged surface 41a of the engaged recess 41 constituting the engaged portion on the end cap 3 side The edge portion 40d of the holding tab 40 constituting the engaging portion on the molding body 2 side is located slightly behind the longitudinal direction Z.

When the insertion portion 7 of the end cap 3 is inserted from the terminal surface 2a side of the molding body 2, the outer peripheral side wall 32 comes into contact with the curved portion 40b of the holding tab 40. Then, a component force is generated from the force for inserting the insertion portion 7 in the longitudinal direction Z in the height direction Y, and the holding tab 40 is pushed up toward the outer peripheral side with the vicinity of the base end portion 40a as a fulcrum (see FIG. 6A). ). When the insertion portion 7 is further inserted into the molding body 2, the engaged recess 41 approaches the holding tab 40 while sliding the outer peripheral surface of the outer peripheral side wall 32 against the folded portion 40c of the holding tab 40.

When the end cap 3 reaches a position where the lid-side facing surface 6a is close to the terminal surface 2a, the position of the engaged recess 41 in the longitudinal direction Z corresponds to the folded-back portion 40c of the holding tab 40. Then, the holding tab 40 released from being pushed up from the outer peripheral side wall 32 toward the outer peripheral side with respect to the folded-back portion 40c eliminates the bending toward the outer peripheral side and returns to a position substantially parallel to the vehicle width direction portion 5. As a result, as shown in FIG. 6B, the folded-back portion 40c enters the engaged recess 41, and the edge portion 40d of the folded-back portion 40c faces the engaged surface 41a of the engaged recess 41. The engagement surface 41a abuts (engages) with the edge portion 40d, so that the movement of the end cap 3 toward the terminal side in the longitudinal direction Z is restricted. That is, the end cap 3 cannot be removed from the molding body 2 to the terminal side.

As described above, the distance (L4) from the terminal surface 2a of the molding body 2 in the free state to the edge 40d of the holding tab 40 is the engagement of the engaged recess 41 from the lid-side facing surface 6a of the end cap 3. It is slightly larger than the distance (L3) to the meeting surface 41a. As a result, in a state where the engaged surface 41a abuts (engages) the edge portion 40d as shown in FIG. 6B, a force that pulls the holding tab 40 toward the terminal side in the longitudinal direction Z is applied. This force causes bending in a state where the curved portion 40b of the holding tab 40 extends in the longitudinal direction Z (moves the folded portion 40c toward the terminal side), and a force for eliminating the bending is applied from the edge portion 40d. It is transmitted to the mating surface 41a, and the engaged recess 41 receives a force from the holding tab 40 and is urged to the inner side in the longitudinal direction Z. That is, the holding tab 40 functions as a pulling means for applying an urging force to the back side in the longitudinal direction Z with respect to the end cap 3 due to the bending generated in the curved portion 40b (deflecting portion).

Therefore, the engagement between the engaged recess 41 and the folded-back portion 40c of the holding tab 40 restricts the insertion portion 7 from coming off to the terminal side in the longitudinal direction Z, and is engaged from the holding tab 40. An urging force is applied to the recess 41 in the longitudinal direction Z to pull it toward the back side, so that the lid portion 6 comes into close contact with the terminal surface 2a of the molding body 2. That is, in the molding 1A, the same effect as that of the molding 1 described above can be obtained with respect to the positioning and the assembling property of the end cap 3 in the longitudinal direction Z with respect to the molding main body 2.

The holding tab 40 separated from the other portion of the molding body 2 in the vehicle width direction X by the notch 42 can also bend in the vehicle width direction X. By bending the holding tab 40 in the vehicle width direction X, the accuracy error in the vehicle width direction X existing between the molding body 2 and the end cap 3 can be absorbed, or the side surface of the engaged recess 41 can be moved in the vehicle width direction X. The position accuracy of the end cap 3 in the vehicle width direction X can be improved by auxiliary urging.

Unlike the form shown in FIG. 6A, the molding 1A can be configured so that the end cap 3 side is deformed when the insertion portion 7 is inserted into the molding body 2. For example, the tip of the insertion portion 7 (the end on the inner side in the longitudinal direction Z) abuts on the tip of the holding tab 40 (the curved portion 40b), and the force for inserting the insertion portion 7 in the longitudinal direction Z causes the height direction Y. When a component force is generated, the outer peripheral side wall 32 of the end cap 3 may be pushed toward the inner peripheral side to be deformed. When the insertion portion 7 is further inserted into the molding body 2, the pushed state of the outer peripheral side wall 32 toward the inner peripheral side is canceled, and the engaged recess 41 engages with the folded portion 40c of the holding tab 40 (B). It becomes the state of.

Further, both the holding tab 40 on the molding body 2 side and the outer peripheral side wall 32 on the end cap 3 side may be deformed when the folded-back portion 40c and the engaged recess 41 are engaged.

The molding 1 and the molding 1A have a protrusion (engaged protrusion 38, folded portion 40c) on one of the molding body 2 and the end cap 3 as a configuration for determining the position of the end cap 3 in the longitudinal direction Z. It is common in that a hole (engagement hole 23) or a recess (engaged recess 41) with which the protrusion can be engaged is provided on the other side of the molding body 2 and the end cap 3.

FIG. 7 shows a molding 1B which is a second modification. In the mall 1B, the parts common to the mall 1 described above are indicated by the same reference numerals and the description thereof will be omitted.

An engaging hole 45 penetrating in the height direction Y is formed in the vehicle width direction portion 5 of the molding body 2 constituting the molding 1B. The engaging hole 45 is substantially rectangular in a plan view, and a hole edge portion 45a facing the inner surface in the longitudinal direction Z is formed as a part of the inner surface of the engaging hole 45.

The molding body 2 is further provided with a flexible portion 46. The bent portion 46 is a standing wall 46a protruding from the vicinity of the terminal surface 2a of the vehicle width direction portion 5 toward the outer peripheral side, and a U bent and folded back from the outer peripheral side end portion of the standing wall 46a toward the terminal side in the longitudinal direction Z. It is a cantilever-shaped protrusion having a curved portion 46b having a character shape and a folded portion 46c extending inward from the curved portion 46b. The folded-back portion 46c is located at a position protruding toward the terminal side from the terminal surface 2a. The vertical wall 46a and the folded-back portion 46c face each other with a distance in the longitudinal direction Z. The bent portion 46 can be bent so as to change the distance between the vertical wall 46a and the folded portion 46c in the longitudinal direction Z.

Although the end cap constituting the molding 1B is not shown, it has an engaged portion similar to the engaged surface 38a of the engaged projection 38 in the end cap 3 of the molding 1 described above. By engaging this engaged portion with the hole edge portion 45a of the engaging hole 45, which is the engaging portion on the molding body 2 side, the end cap inserted into the molding body 2 is moved to the terminal side in the longitudinal direction Z. It is held so that it will not come off.

When the engaged portion of the end cap engages with the hole edge portion 45a of the engagement hole 45, the portion of the end cap facing the terminal surface 2a (not shown) hits the folded portion 46c of the bending portion 46. Contact and push it to the back side in the longitudinal direction Z. As a result, the bending portion 46 causes bending that reduces the distance between the folded portion 46c and the standing wall 46a in the longitudinal direction Z. The force for eliminating the bending is transmitted from the hole edge portion 45a to the engaged portion of the end cap, and the end cap is urged to the inner side in the longitudinal direction Z. That is, the flexible portion 46 functions as a pulling means for applying an urging force to the back side in the longitudinal direction Z with respect to the end cap.

In the above-mentioned molding 1 and molding 1A, the engaging portion (hole edge portion 23a of the engaging hole 23, the edge portion 40d of the folded portion 40c) for preventing the retaining portion from coming off toward the terminal in the longitudinal direction Z, and the back in the longitudinal direction Z. The means for pulling in to the side (bending portion 22, curved portion 40b) are collectively provided in the holding tab 20 and the holding tab 40. On the other hand, in the molding 1B, the bending portion 46, which is a pull-in means, is formed as a protruding portion independent of the engaging portion for preventing the retaining (the hole edge portion 45a of the engaging hole 45). As can be seen from the above embodiments and each modification, various arrangements and configurations can be selected for the engaging portion and the retracting means provided in the molding body. Correspondingly, it is possible to select various arrangements and configurations of the engaged portion provided on the end cap.

In the above embodiment and each modification, the end member assembled to the end portion of the molding body 2 is the end cap 3 having the lid portion 6 and the insertion portion 7, but it may be applied to the end member other than the end cap. It is possible.

Although the above-mentioned mall 1 (1A, 1B) is an example of application to an upper sash mall, the present invention can be applied to a mall other than the upper sash mall. For example, it can be applied to a belt molding along the lower edge of the window opening, a frame molding along the corner of the window opening by connecting the upper sash molding and the belt molding, and the like. Further, it can be applied to a mall attached to a portion of a vehicle door other than the peripheral edge of a window opening, a molding provided on a vehicle body portion other than the door, and the like. That is, the present invention can be applied to all types of malls for vehicles.
