Description

[Technical Field]

[0001] The present invention relates to a glass run for an automobile that is attached to a sash frame of an automobile door to provide a seal between the sash frame and the door glass, and to a glass run unit that includes the same. [Background technology]

[0002] Glass runs are widely used as a means for sealing between the door glass and the sash frame that constitutes the window frame of an automobile door glass. In addition to having a sealing function, glass runs also have the function of guiding the door glass as it moves up and down. Known glass runs include a strip-shaped molding attached along the outer side of the upper edge of the vehicle to improve the exterior design and give the automobile a luxurious feel (see, for example, Patent Document 1). The molding is configured to be attached to the glass run by engaging with the glass run. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-012750 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the position of the molding member is misaligned relative to the glass run in the fore-and-aft direction of the vehicle, it may result in a deterioration in the appearance. In this regard, the conventional glass run described above is provided with a protrusion that the molding member can abut against from the front of the vehicle as a displacement prevention means for preventing the molding member attached to the glass run from being displaced rearward due to the opening and closing of the door.

[0005] However, because misalignment of the molding with respect to the glass run can occur even when the molding is attached to the glass run, a technique is needed to attach the molding without misalignment in the fore-and-aft direction of the vehicle relative to the glass run, in other words, to position the molding when attaching the molding. Here, because the molding is attached to the glass run by engaging with the glass run as described above, there is a problem in that once attached to the glass run, it is extremely difficult to move the molding in the fore-and-aft direction of the vehicle due to the restriction of the molding by the engaging portion. To solve this problem, the present inventor began to study a means for positioning the molding with respect to the glass run while the molding is being attached to the glass run, i.e., before the molding is fully engaged with the glass run.

[0006] Furthermore, while studying means for positioning the molding, the inventors came up with the idea of ​​arranging the positioning portion for positioning the molding so that it would be difficult to see from the outside of the vehicle, so as not to affect the appearance. This inevitably led to the problem that the positioning work of the molding would be a so-called blind work, where it was difficult for the worker to visually check. However, the inventors found a means for ensuring good workability in order to overcome this issue, and then completed the present invention.

[0007] The present invention has been made in consideration of the above, and aims to provide a glass run for an automobile door that can position a molding member in the fore-and-aft direction of the vehicle while ensuring good workability when attaching the molding member to the glass run, and a glass run unit equipped with the same. [Means for solving the problem]

[0008] In order to achieve the above object, the glass run of the present invention is configured as follows: The glass run of the present invention is a glass run for an automobile door that is attached to a sash frame having an upper frame portion extending in the fore-and-aft direction of the vehicle, and a front frame portion and a rear frame portion extending downward from the front and rear ends of the upper frame portion, and that seals between the sash frame and the door glass, and that has an upper edge portion attached to the upper frame portion, a front edge portion attached to the front frame portion, a rear edge portion attached to the rear frame portion, a front connection portion that connects the front end of the upper edge portion to the upper end of the front edge portion, and a rear connection portion that connects the rear end of the upper edge portion to the upper end of the rear edge portion, and is configured so that a strip-shaped molding member can be attached to the exterior side of the vehicle from the front connection portion to the rear connection portion so as to follow the upper edge portion. The molding member has an upper engaging portion and a lower engaging portion extending in the longitudinal direction at the upper and lower portions on the back surface thereof, and the longitudinal ends of the lower engaging portions are located longitudinally inward of the longitudinal ends of the molding member. The front connecting portion, the upper edge portion, and the rear connecting portion have upper engaging grooves and lower engaging grooves extending in the fore-and-aft direction of the vehicle, which are configured to be engageable with the upper engaging portion and the lower engaging portion, respectively. A molding engaging member made of a hard material harder than the portion that comes into contact with the door glass is provided on the vehicle exterior side of at least one of the front connection portion and the rear connection portion, and the molding engaging member is provided with an engaged portion in which a groove portion that forms the vehicle longitudinal end portion of the lower engaging groove is formed, and a positioning portion that can be abutted against the longitudinal end portion of the lower engaging portion along the vehicle longitudinal direction when the lower engaging portion is engaged with the groove portion and the upper engaging portion is not engaged with the upper engaging groove, and is configured so that the molding member is positioned in the vehicle longitudinal direction when the lower engaging portion abuts against it, and the positioning portion protrudes below the lower end edge of the engaged portion.

[0009] According to the above configuration, the front connection portion, the upper edge portion, and the rear connection portion are provided with upper engagement grooves and lower engagement grooves configured to be engageable with the upper engagement portions and lower engagement portions of the molding, respectively, so that the molding can be attached to the exterior side of the vehicle from the front connection portion to the rear connection portion along the upper edge portion by engaging the upper engagement portions and the lower engagement grooves, respectively. Furthermore, the molding engagement member made of a hard material harder than the portion that contacts the door glass is provided on the exterior side of at least one of the front connection portion and the rear connection portion, and the molding engagement member is provided with an engaged portion having a groove portion that forms the vehicle front-rear direction end of the lower engagement groove. Therefore, the vehicle front-rear direction end of the lower engagement groove can be made of a hard material that is relatively resistant to deformation, and therefore the lower engagement portion of the molding can be more reliably engaged with the lower engagement groove.

[0010] Furthermore, the above-mentioned molding engaging member is provided with a positioning portion that allows the longitudinal end of the lower engaging portion to be abutted along the fore-and-aft direction of the vehicle when the lower engaging portion is engaged with the groove portion and the upper engaging portion is not engaged with the upper engaging groove, and is configured so that the molding member is positioned in the fore-and-aft direction of the vehicle when the lower engaging portion abuts against it.Therefore, when attaching the molding member to the glass run, the lower engaging portion can first be engaged with the groove portion, i.e., before the molding member is fully engaged with the glass run, and then the lower engaging portion can be abutted against the positioning portion to position the molding member in the fore-and-aft direction of the vehicle.

[0011] Furthermore, because the longitudinal end of the lower engaging portion of the molding is positioned longitudinally inward relative to the longitudinal end of the molding, the positioning portion against which the longitudinal end of the lower engaging portion abuts can be positioned so that it is hidden by the molding, i.e., so that it is difficult to see from outside the vehicle. On the other hand, the positioning work of the molding when attaching the molding to the glass run is inevitably a blind operation. However, to ensure good workability, the configuration allows the position of the positioning portion to be confirmed even in blind operation. Specifically, by making the positioning portion protrude below the lower edge of the engaged portion, the positioning portion can be easily recognized by touch. This allows the molding to be smoothly (without delay) positioned relative to the glass run while appropriately checking the position of the positioning portion with a finger. Therefore, good workability can be ensured even when the positioning work of the molding is blind operation. In addition, as an additional effect, since the positioning portion protrudes below the lower edge of the engaged portion, the positioning portion is easily visible when not hidden by the molding, so that the worker can easily check the position of the positioning portion before attaching the molding to the glass run, and therefore the molding can be positioned more smoothly relative to the glass run.In this way, with the above configuration, the molding can be positioned in the fore-and-aft direction of the vehicle while ensuring good workability when attaching the molding to the glass run.

[0012] In the above-described glass run for a vehicle door, the engaged portion and the positioning portion may be integrally formed, thereby improving the rigidity of both.

[0013] In the above-described glass run for an automobile door, the positioning portion may be provided with an abutment surface portion, the normal direction of which is the longitudinal direction of the vehicle, against which the longitudinal end of the lower engagement portion abuts, and an inclined surface portion extending obliquely downward from the lower edge of the abutment surface portion in a direction opposite to the direction of the abutment surface portion and configured to guide the longitudinal end of the lower engagement portion to the abutment surface portion when it comes into contact with the longitudinal end of the lower engagement portion. This allows the longitudinal end to be guided to the abutment surface portion even if the longitudinal end of the lower engagement portion of the molding is positioned opposite to the direction of the abutment surface portion when the worker brings the molding member close to the glass run, and also allows the molding member to be positioned in the longitudinal direction of the vehicle by abutting the lower engagement portion against the positioning portion, as described above.

[0014] The glass run unit according to the present invention includes the glass run for an automobile door and the molding member, and as described above, when attaching the molding member to the glass run, the molding member can be positioned in the fore-and-aft direction of the vehicle while ensuring good workability. [Effects of the Invention]

[0015] As described above, according to the present invention, when attaching a molding member to a glass run, the molding member can be positioned in the vehicle longitudinal direction while ensuring good workability. [Brief explanation of the drawings]

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a left side view showing a part of an automobile A to which a glass run unit B according to a first embodiment is attached. FIG. 2 is a cross-sectional view showing the center part of an upper frame portion 110 of a sash frame 11 and its surrounding area. FIG. 2 shows a cross section taken along line AA in FIG. 1. In the following drawings, the longitudinal direction of the vehicle is indicated by the symbol X. Hereinafter, the direction toward the inside of the vehicle may be referred to as the inward direction, and the direction toward the outside of the vehicle may be referred to as the outward direction. The glass run unit B according to the first embodiment of the present invention is attached to a door that opens and closes a door opening 90 of an automobile A. In the following, in the first embodiment, the configuration of a front door 1 used as an example of a door will first be described, and then the configuration of the glass run unit B will be described.

[0018] <Front door> As shown in FIG. 1, the front door 1 includes a door body 10 and a sash frame 11 that is disposed above the door body 10 and forms a window frame for a door glass W.

[0019] The front end of the door body 10 is attached to a front pillar via a hinge (not shown) having a rotation axis extending in the vertical direction. The door body 10 has a structure in which an inner panel (not shown) and an outer panel 100, both made of steel plate or the like, are joined at their peripheral edges, forming an internal space. The internal space of the door body 10 accommodates a mechanism for raising and lowering the door glass W, reinforcing members for reinforcing the door body 10, and the lowered door glass W.

[0020] As shown in FIG. 1, the sash frame 11 is provided so as to protrude upward from between the inner panel and outer panel 100 of the door body 10. The sash frame 11 has an upper frame portion 110 extending in the longitudinal direction of the vehicle, and a front frame portion 111 and a rear frame portion 112 extending downward from the front and rear ends of the upper frame portion 110, and has an opening 11a for a door glass W formed in the center. The opening 11a is opened and closed by the door glass W moving up and down. As shown in FIG. 2, the sash frame 11 is formed by overlapping and joining an inner sash 115 on the inner periphery of the opening 11a and an outer sash 116 on the outer periphery of the opening 11a, and this joint is formed into a flange shape facing the exterior of the vehicle, thereby forming a mounting flange portion 12 to which a glass run unit B is attached.

[0021] 1, the upper frame portion 110 is formed to be gently curved along the roof-side edge portion 91 of the vehicle body. The front frame portion 111 and the rear frame portion 112 extend parallel to each other in the lifting and lowering direction of the door glass W. The lower ends of the front frame portion 111 and the rear frame portion 112 are fixed inside the door body 10.

[0022] <Glass Run Unit> Fig. 3 is a side view of the glass run unit B in the first embodiment as seen from the outside of the vehicle. Next, the configuration of the glass run unit B in the first embodiment will be described. As shown in Fig. 3, the glass run unit B is attached to the sash frame 11 and includes a glass run 2 (a glass run for an automobile door) that seals the gap between the sash frame 11 and the door glass W, and a decorative strip-shaped molding member 3 that is attached to the glass run 2 on the outside of the vehicle. Each of these components will be described below.

[0023] -Graslin- In addition to the above-mentioned sealing function, the glass run 2 also has the function of guiding the raising and lowering of the door glass W along the front frame portion 111 and the rear frame portion 112 of the sash frame 11. As shown in Fig. 2, the glass run 2 is a so-called hidden type glass run that is configured to cover the exterior side of the upper frame portion 110.

[0024] 1 and 3, the glass run 2 has an upper edge portion 20 attached to the upper frame portion 110 of the sash frame 11, a front edge portion 21 attached to the front frame portion 111, a rear edge portion 22 attached to the rear frame portion 112, a parting seal portion 23 disposed forward of the front edge portion 21 and attached to the front end of the front door 1, as well as a front connection portion 24 and a rear connection portion 25. The front connection portion 24 connects the front end of the upper edge portion 20, the upper end of the front edge portion 21, and the upper end of the parting seal portion 23, and the rear connection portion 25 connects the rear end of the upper edge portion 20 and the upper end of the rear edge portion 22.

[0025] The top edge portion 20, the front edge portion 21, the rear edge portion 22, and the parting seal portion 23 are made of a rubber material such as a thermoplastic elastomer and are formed by extrusion molding. The front connection portion 24 and the rear connection portion 25 are formed by molding, with an insert member made of a hard resin material (e.g., fiber-reinforced resin) or the like embedded in a molding material made of a rubber material or the like. The top edge portion 20, the front edge portion 21, and the parting seal portion 23 are joined together as the front connection portion 24 is molded by injecting molding material for the front connection portion 24 while the front end of the top edge portion 20, the upper end of the front edge portion 21, and the upper end of the parting seal portion 23 are placed in a mold for the front connection portion 24. Similarly, the top edge portion 20 and the rear edge portion 22 are joined together as the rear connection portion 25 is molded by injecting molding material for the rear connection portion 25 while the rear end of the top edge portion 20 and the upper end of the rear edge portion 22 are placed in a mold for the rear connection portion 25. The dashed dotted lines in FIG. 3 conceptually show the boundaries of the above-mentioned portions of the glass run 2.

[0026] Next, the configurations of the upper edge portion 20, the front connection portion 24, and the rear connection portion 25 will be described in more detail. Note that the front edge portion 21, the rear edge portion 22, and the parting seal portion 23 are not important for explaining the present invention, so their description will be omitted. As shown in Fig. 2, the upper edge portion 20 includes an upper wall portion 200 that fits along the upper surface of the mounting flange portion 12 in the upper frame portion 110 of the sash frame 11, a lower wall portion 201 that fits along the lower surface of the mounting flange portion 12, and a side wall portion 202 that connects the vehicle exterior end of the upper wall portion 200 and the vehicle exterior end of the lower wall portion 201.

[0027] 2, an upper lip portion 203 that protrudes upward is provided on the upper surface of the upper wall portion 200. The upper lip portion 203 is adapted to elastically deform upon contact with the door opening 90 of the vehicle body. In addition, a plurality of lower lip portions 204 that protrude downward are provided on the lower surface of the upper wall portion 200. The lower lip portions 204 are adapted to elastically deform upon contact with the upper surface of the mounting flange portion 12.

[0028] Furthermore, the upper edge portion 20 includes an outer lip portion 205 extending downward from the underside of the lower wall portion 201, an inner lip portion 206 extending downward from the underside of the lower wall portion 201 on the vehicle interior side of the outer lip portion 205, and a center lip portion 207 extending downward from the underside of the lower wall portion 201 between the outer lip portion 205 and the inner lip portion 206. The tip of the outer lip portion 205 is bent inward and elastically deforms upon contact with the exterior side of the raised door glass W. The tip of the inner lip portion 206 branches out onto the exterior and interior sides, and an exterior lip end portion 208 branching out on the exterior side is elastically deformed upon contact with the interior side of the raised door glass W, while an interior lip end portion 209 branching out on the interior side follows the upper frame portion 110 so as to cover the upper frame portion 110 from the exterior side of the vehicle. The center lip portion 207 is formed shorter than the outer lip portion 205 and the inner lip portion 206, and is elastically deformed by contact with the upper end of the raised door glass W.

[0029] The outer lip portion 205, inner lip portion 206, and center lip portion 207 contact the raised door glass W and elastically deform, thereby sealing the gap between the upper edge portion 20 and the door glass W. The portions that come into contact with the door glass W, such as the outer lip portion 205, inner lip portion 206, and center lip portion 207, are made of rubber material.

[0030] Fig. 4 is a cross-sectional view showing the front end portion of the upper frame portion 110 of the sash frame 11 and its surrounding area. Fig. 4 shows the B-B cross section of Fig. 1. As shown in Fig. 4, like the upper edge portion 20, the front connection portion 24 includes an upper wall portion 240 that fits along the upper surface of the mounting flange portion 12 of the upper frame portion 110 of the sash frame 11, a lower wall portion 241 that fits along the lower surface of the mounting flange portion 12, and a side wall portion 242 that connects the vehicle exterior end portion of the upper wall portion 240 and the vehicle exterior end portion of the lower wall portion 241. The upper half portions of the upper wall portion 240 and the side wall portion 242 of the front connection portion 24 are made of a molding material (such as rubber), and the lower half portions of the lower wall portion 241 and the side wall portion 242 of the front connection portion 24 are made of an insert member (such as hard resin material).

[0031] Fig. 5 is a cross-sectional view showing the rear end portion of the upper frame portion 110 of the sash frame 11 and its surrounding area. Fig. 5 shows the CC cross section of Fig. 1. As shown in Fig. 5, like the front connection portion 24, the rear connection portion 25 includes an upper wall portion 250 that fits along the upper surface of the mounting flange portion 12 of the upper frame portion 110 of the sash frame 11, a lower wall portion 251 that fits along the lower surface of the mounting flange portion 12, and a side wall portion 252 that connects the vehicle exterior end portion of the upper wall portion 250 and the vehicle exterior end portion of the lower wall portion 251, and the upper half portions of the upper wall portion 250 and the side wall portion 252 of the rear connection portion 25 are made of a molding material (such as a rubber material), and the lower half portions of the lower wall portion 251 and the side wall portion 252 of the rear connection portion 25 are made of an insert member (such as a hard resin material).

[0032] The glass run 2 configured as described above is configured so that the molding member 3 can be attached to the exterior side of the vehicle from the front connection portion 24 to the rear connection portion 25 along the upper edge portion 20. More specifically, as shown in FIGS. 2 , 4 , and 5 , the front connection portion 24, the upper edge portion 20, and the rear connection portion 25 are provided with upper engagement grooves 26 and lower engagement grooves 27 that are configured to be engageable with upper engagement portions 30 and lower engagement portions 31 of the molding member 3, which will be described later, respectively, and that extend in the fore-and-aft direction of the vehicle. The upper engagement grooves 26 and the lower engagement grooves 27 are disposed at the top and bottom of the side wall portions 202, 242, and 252 of the front connection portion 24, the upper edge portion 20, and the rear connection portion 25, respectively, and extend parallel to each other. The upper engagement groove 26 is formed to open upward, while the lower engagement groove 27 is formed to open downward.

[0033] -Molding parts- 6 is a perspective view of a portion of the molding member 3 in the first embodiment, seen from the back side. The molding member 3 is made of, for example, a metal material such as aluminum or stainless steel, or a hard resin material, and is formed by extrusion molding. The longitudinal end portion 3a of the molding member 3 is formed by, for example, bending the end portion after extrusion molding. Although not shown, the surface of the molding member 3 (the surface facing the exterior of the vehicle when attached to the glass run 2) is coated with a decorative sheet material, film material, paint, or the like. The direction perpendicular to the longitudinal direction of the molding member 3 and the normal direction to the surface is sometimes referred to as the band width direction.

[0034] As shown in FIG. 6 , upper and lower engagement portions 30 and 31 are provided on the upper and lower portions of the rear surface of the molding member 3, extending in the longitudinal direction. The upper engagement portion 30 protrudes from the rear surface of the molding member 3 in the normal direction to the rear surface and then bends downward so that its cross section perpendicular to the longitudinal direction has an inverted L-shape, while the lower engagement portion 31 protrudes from the rear surface of the molding member 3 in the normal direction to the rear surface and then bends upward so that its cross section perpendicular to the longitudinal direction has an L-shape. The upper engagement portion 30 is engaged with the upper engagement groove 26, thereby engaging with the upper engagement groove 26. Similarly, the lower engagement portion 31 is engaged with the lower engagement groove 27, thereby engaging with the lower engagement groove 27. A longitudinal end 300 of the upper engagement portion 30 and a longitudinal end 310 of the lower engagement portion 31 are formed by cutting or the like and are located longitudinally inward of the longitudinal end 3a of the molding member 3.

[0035] The molding member 3 configured as described above is fully engaged with the glass run 2 when the upper engagement portion 30 engages with the upper engagement groove 26 of the glass run 2 and the lower engagement portion 31 engages with the lower engagement groove 27. Hereinafter, the upper engagement portion 30, the lower engagement portion 31, the upper engagement groove 26, and the lower engagement groove 27 may be collectively referred to as the "engagement portions." The procedure for attaching the molding member 3 to the glass run 2 will be explained in detail later, but when attaching the molding member 3, first, the lower engagement portion 31 is engaged with the lower engagement groove 27, and then the upper engagement portion 30 is engaged with the upper engagement groove 26. In this way, the molding member 3 is attached to the glass run 2 by fully engaging with the glass run 2.

[0036] -Molding engagement parts- FIG. 7 is a side view of the front connection portion 24 of the glass run 2 in the first embodiment and its surrounding area as viewed from the vehicle exterior. Note that the groove portion 40 is not visible in FIG. 7. FIG. 8 is a perspective view of the molding engagement member 4 in the first embodiment as viewed from the vehicle exterior. FIG. 9 is a cross-sectional view showing the molding engagement member 4 and its surrounding area. Note that hatching is omitted in FIG. 9 for convenience of illustration. In order to reliably engage the molding member 3 with the glass run 2 when attaching it to the glass run 2, as shown in FIG. 7, a molding engagement member 4 is provided on the vehicle exterior side of the front connection portion 24 of the glass run 2 in the first embodiment. The molding engagement member 4 is made of an insert member (hard resin material or the like) in the front connection portion 24, and in short, is formed from a hard material that is harder than the portion (rubber material or the like) that comes into contact with the door glass W.

[0037] 7 to 9, the molding engaging member 4 is provided with an engaged portion 41 in which a groove portion 40 that constitutes the vehicle longitudinal direction end portion of the lower engaging groove 27 is formed, and a positioning portion 42 that is arranged outside the engaged portion 41 in the vehicle longitudinal direction and is configured to position the molding member 3 in the vehicle longitudinal direction. The engaged portion 41 and the positioning portion 42 are integrally formed.

[0038] 8 and 9, engaged portion 41 is formed to protrude outward from front connecting portion 24, and groove 40 is formed to open downward by hollowing out the interior of engaged portion 41. In this way, by providing engaged portion 41 with groove 40 formed in molding engaging member 4, the vehicle front-rear direction end of lower engaging groove 27 can be made of a hard material that is relatively resistant to deformation, and therefore lower engaging portion 31 of molding member 3 can be more reliably engaged with lower engaging groove 27.

[0039] The positioning portion 42 is configured so that when the lower engagement portion 31 of the molding member 3 is engaged with the groove portion 40 and the upper engagement portion 30 is not engaged with the upper engagement groove 26, the longitudinal end portion 310 of the lower engagement portion 31 can be abutted against it along the fore-and-aft direction of the vehicle, and the abutment of the lower engagement portion 31 positions the molding member 3 in the fore-and-aft direction of the vehicle.

[0040] 8, the positioning portion 42 has an abutment surface 420, normal to the vehicle longitudinal direction, against which the lower engaging portion 31 abuts. More specifically, the abutment surface 420 faces inward in the vehicle longitudinal direction, faces the longitudinal end 310 of the lower engaging portion 31 of the molding member 3 when it is about to be attached to the glass run 2, and is adjacent to the longitudinal end 310 of the lower engaging portion 31 of the molding member 3 when it is attached to the glass run 2.

[0041] 8 and 9, the positioning portion 42 protrudes downward from the lower edge 410 of the engaged portion 41. This makes the positioning portion 42 easily recognizable by touch, and for example, when an operator touches the molding engaging member 4, the operator can easily recognize that the portion protruding relatively downward is the positioning portion 42. The protrusion amount d of the positioning portion 42 from the lower edge 410 of the engaged portion 41 (see FIG. 8) is, for example, approximately 1 to 5 mm. Furthermore, because the positioning portion 42 protrudes downward from the lower edge 410 of the engaged portion 41, the positioning portion 42 can be easily recognized visually when it is not hidden by the molding member 3.

[0042] <Installation procedure for molding components> 10 to 12 are schematic diagrams (1) to (3) illustrating the procedure for attaching the molding member 3 to the glass run 2. Next, the procedure for attaching the above-described molding member 3 to the glass run 2 will be described. First, as shown in FIG. 10, the molding member 3 is held at an angle so that the width direction of the molding member 3 intersects with the up-down direction, and the lower part of the molding member 3 is brought close to the glass run 2, and then the lower engagement portion 31 is engaged with the lower engagement groove 27 (including the groove portion 40 in the molding engagement member 4). At this time, although not shown in the drawings, the upper engagement portion 30 is not yet engaged with the upper engagement groove 26.

[0043] Next, as shown in FIG. 11 , with the lower engaging portion 31 engaged with the lower engaging groove 27 and the upper engaging portion 30 not engaged with the upper engaging groove 26, the longitudinal end 310 of the lower engaging portion 31 is abutted against the abutment surface 420 of the positioning portion 42 along the vehicle longitudinal direction, thereby positioning the molding member 3 in the vehicle longitudinal direction. As described above, because the positioning portion 42 is disposed outward of the engaged portion 41 in the vehicle longitudinal direction, the lower engaging portion 31 is abutted against the positioning portion 42 from the inside in the vehicle longitudinal direction, as shown by arrow F1 in FIG. 11 . At this time, because the upper engaging portion 30 is not engaged with the upper engaging groove 26, the molding member 3 is in a state before it is completely engaged with the glass run 2. Therefore, because the engaging portion does not completely restrain the molding member 3, the molding member 3 can be easily moved in the vehicle longitudinal direction. Furthermore, by abutting the lower engaging portion 31 against the positioning portion 42 along the vehicle longitudinal direction, the molding member 3 can be positioned in the vehicle longitudinal direction.

[0044] Finally, as shown in Figure 12, the molding member 3 is rotated around the lower engagement portion 31 in the direction of rotation indicated by arrow F2 in Figure 12 so that the strip width direction of the molding member 3 is aligned with the vertical direction, thereby bringing the upper part of the molding member 3 closer to the glass run 2, and then the upper engagement portion 30 is engaged with the upper engagement groove 26. This brings the molding member 3 into complete engagement with the glass run 2. In this way, the molding member 3 is attached to the glass run 2.

[0045] As described above, since the longitudinal end 310 of the lower engaging portion 31 of the molding member 3 is located longitudinally inward of the longitudinal end 3a of the molding member 3, the positioning portion 42 against which the longitudinal end 310 of the lower engaging portion 31 abuts is arranged so as to be hidden by the molding member 3, that is, so as to be difficult to see from outside the vehicle. For this reason, the positioning work of the molding member 3 described above is inevitably a so-called blind work in which it is difficult for an operator to visually confirm.

[0046] Here, because the positioning work of the molding member 3 is a blind work, if the position of the positioning portion 42 cannot be confirmed at all during the positioning work of the molding member 3, for example, the relative position of the positioning portion 42 with respect to the longitudinal end portion 310 of the lower engaging portion 31 cannot be confirmed, making it difficult to confirm whether the lower engaging portion 31 has truly abutted against the positioning portion 42, which may result in a delay in the positioning work of the molding member 3, such as having to redo the positioning work of the molding member 3. In this regard, because the positioning portion 42 is easily tactilely recognizable as described above, the position of the positioning portion 42 can be appropriately confirmed with a finger during the positioning work of the molding member 3, and therefore the molding member 3 can be smoothly positioned relative to the glass run 2 without the above-mentioned delay.

[0047] Furthermore, as described above, the positioning portion 42 is easily visually recognizable when not hidden by the molding member 3, so that the worker can easily check the position of the positioning portion 42 in advance before attaching the molding member 3 to the glass run 2 (before bringing the molding member 3 close to the glass run 2 as shown in Figure 10), and therefore the molding member 3 can be positioned more smoothly (without delay) relative to the glass run 2.

[0048] According to the glass run 2 and glass run unit B described above, the molding engaging member 4 is provided with a positioning portion 42, so that the molding member 3 can be positioned in the fore-and-aft direction of the vehicle by abutting the lower engaging portion 31 against the positioning portion 42 before the molding member 3 is fully engaged with the glass run 2. Furthermore, because the positioning portion 42 protrudes downward from the lower edge 410 of the engaged portion 41, the molding member 3 can be smoothly (without delay) positioned relative to the glass run 2 while appropriately checking the position of the positioning portion 42 with a finger. Therefore, good workability can be ensured even though the positioning work of the molding member 3 is a blind work. In this way, according to the glass run 2 and glass run unit B described above, when attaching the molding member 3 to the glass run 2, the molding member 3 can be positioned in the fore-and-aft direction of the vehicle while good workability is ensured.

[0049] Furthermore, as described above, the engaged portion 41 and the positioning portion 42 are integrally formed, which allows the rigidity of both to be improved.

[0050] In the above embodiment, an example was used in which the molding engaging member 4 was provided on the vehicle exterior side of the front connection portion 24, but this is not limiting, and the molding engaging member 4 may be provided on the vehicle exterior side of the rear connection portion 25. Even in this case, as in the above, the molding engaging member 4 is provided with the positioning portion 42, which has the effect of ensuring good workability when attaching the molding member 3 to the glass run 2 and positioning the molding member 3 in the fore-and-aft direction of the vehicle.

[0051] Fig. 13 is a perspective view of a molding engaging member 4A in one modification, as viewed from the vehicle exterior. Note that, in the above embodiment, an example was used in which the engaged portion 41 and the positioning portion 42 were integrally formed, but this is not limiting. As shown in Fig. 13, the engaged portion 41A and the positioning portion 42A may be formed as separate bodies. Even in this case, similar to the above, when attaching the molding member 3 to the glass run 2, the molding member 3 can be positioned in the vehicle fore-and-aft direction while ensuring good workability.

[0052] In the above embodiment, the positioning portion 42 is positioned further outward in the vehicle longitudinal direction than the engaged portion 41, and therefore an example is used in which the lower engaging portion 31 engaged with the groove portion 40 in the engaged portion 41 is abutted against the positioning portion 42 from the inside in the vehicle longitudinal direction, but this is not limited to this, and the positioning portion 42 may also be positioned further inward in the vehicle longitudinal direction than the engaged portion 41.

[0053] In the above embodiment, an example was used in which the longitudinal end 300 of the upper engagement portion 30 is located longitudinally inward of the longitudinal end 3a of the molding member 3, but this is not limited to this, and the longitudinal end 300 of the upper engagement portion 30 may be located flush with the longitudinal end 3a of the molding member 3.

[0054] In the above embodiment, the front door 1 has been used as an example, but the present invention can also be applied to other glass run units that are attached to the rear door 9 (see FIG. 1) and the like.

[0055] (Embodiment 2) Fig. 14 is a perspective view of the molding engaging member 7 in the second embodiment as seen from outside the vehicle. Fig. 15 is a side view of the molding engaging member 7 in Fig. 14 as seen from outside the vehicle. Next, the configuration of the glass run 5 in the second embodiment of the present invention will be described, focusing on the differences from the glass run 2 in the first embodiment. Note that the molding member 6 in the second embodiment is the same as the molding member 3 in the first embodiment.

[0056] 14 and 15, the molding engaging member 7 of the glass run 5 in the second embodiment is provided with a positioning portion 72, similar to the case of the first embodiment. In the second embodiment, the positioning portion 72 is provided with an abutting surface portion 720, as well as an inclined surface portion 722 that extends obliquely downward from a lower edge 721 of the abutting surface portion 720 in the opposite direction to the abutting surface portion 720.

[0057] The inclined surface portion 722 is configured to guide the longitudinal end portion 610 to the abutment surface portion 720 when it comes into contact with the longitudinal end portion 610 of the lower engagement portion 61 of the molding member 6. More specifically, when an operator brings the molding member 6 close to the glass run 5, if the longitudinal end portion 610 of the lower engagement portion 61 of the molding member 6 is positioned on the opposite side to the abutment surface portion 720 as shown by the dashed dotted line in FIG. 15 , the longitudinal end portion 610 of the lower engagement portion 61 comes into contact with the inclined surface portion 722. Then, when the longitudinal end portion 610 of the lower engagement portion 61 comes into contact with the inclined surface portion 722, it slides obliquely upward along the inclined surface portion 722 as shown by arrow F3, and is guided to the abutment surface portion 720. The broken line in FIG. 15 shows the molding member 6 after the longitudinal end 610 of the lower engagement portion 61 has been guided to the abutment surface portion 720 by the inclined surface portion 722.

[0058] Because the above-mentioned inclined portion 722 is provided on the positioning portion 72, when the worker brings the molding member 6 close to the glass run 5, even if the longitudinal end portion 610 of the lower engagement portion 61 of the molding member 6 is positioned on the opposite side to the orientation of the abutment surface portion 720, the longitudinal end portion 610 can be guided to the abutment surface portion 720, and as described in embodiment 1, the molding member 6 can be positioned in the fore-and-aft direction of the vehicle by abutting the lower engagement portion 61 against the positioning portion 72.

[0059] The above-described embodiments are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments and examples, but should be defined by the claims. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Explanation of symbols]
