Description

Technical Field

[0001] The present disclosure relates to a seal structure provided on an automotive door.

Background Art

[0002] Conventionally, some automotive doors are provided with a windshield and a window frame for holding the windshield. A glass run for sealing between the window frame and the peripheral edge of the windshield is disposed on the door having this window frame (see, for example, Patent Documents 1 and 2).

[0003] The glass runs of Patent Documents 1 and 2 are configured to be attached to the window frame from the outside of the vehicle compartment. That is, on the upper side portion of the window frame, a glass run mounting plate portion that protrudes outside the vehicle compartment and extends in the vehicle longitudinal direction is formed, while on the upper side portion of the glass run, an insertion groove into which the glass run mounting plate portion can be inserted is formed.

[0004] A notch is formed in the rear portion of the vehicle of the glass run mounting plate portion of Patent Document 1. Further, on the rear portion of the vehicle of the upper side portion of the glass run, an insert member made of a hard resin material is integrated in a state of being insert molded into the main body portion of the glass run. The portion where the insert member is insert molded is a molded portion. On the upper portion of the insert member, a pin that protrudes upward is formed, and when the upper side portion of the glass run is attached to the glass run mounting plate portion, the pin of the insert member is inserted into the notch of the glass run mounting plate portion.

[0005] Further, a hard member is attached to the rear portion of the vehicle of the upper side portion of the glass run of Patent Document 2. The hard member has a clip-shaped portion fixed to the window frame and a support portion that supports a vertical side portion extending downward from the upper side portion of the glass run.

Prior Art Documents

Patent Documents

[0006] [Patent Document 1] International Publication No. 2019 / 043228 Brochure [Patent Document 2] Japanese Patent Publication No. 2021-133846 [Overview of the project] [Problems that the invention aims to solve]

[0007] Incidentally, typical window runs are mainly made of soft rubber (EPDM), soft plastic (TPE), or hard plastic (PP), and these materials have a higher coefficient of thermal expansion than the metal materials that make up the window frame. Therefore, in high-temperature environments such as under direct sunlight, the thermal expansion of the window run is greater than that of the window frame, and there is a risk that the end portion of the upper edge of the window run may protrude in the front-to-back direction more than at room temperature. This not only worsens the appearance, but it could also cause the end portion of the upper edge of the window run to come into contact with a part of the adjacent door, obstructing the opening and closing of the door.

[0008] In response to this, Patent Document 1 suppresses the protrusion of the end portion of the upper edge of the glass run by inserting a pin of an insert material embedded in the upper edge of the glass run into a notch in the glass run mounting plate. However, the presence of an insert material worsens the moldability of the molded portion of the glass run and complicates the mold mechanism, and also imposes significant constraints on the cross-sectional shape of the extruded portion during die-cutting. Furthermore, because welding to the molded portion of the glass run is required, the material of the insert material is limited, which is another problem.

[0009] Therefore, a configuration in which a rigid member that is not insert-molded is provided, as in Patent Document 2, can be considered. However, the support portion of the rigid member in Patent Document 2 is the part that supports the vertical edge of the glass run, and not the part that directly supports the upper edge of the glass run. For this reason, it is conceivable that the effect of suppressing the protrusion of the end portion of the upper edge of the glass run in a high-temperature atmosphere is insufficient.

[0010] This disclosure is made in view of the above points, and its purpose is to suppress the protrusion of the terminal portion of the upper edge of the glass run in a high-temperature atmosphere without causing deterioration of moldability, and while improving the degree of freedom in setting the cross-sectional shape and selecting materials. [Means for solving the problem]

[0011] To achieve the above objective, a first aspect of this disclosure may provide a sealing structure for an automobile door, comprising a glass run made of at least one of resin and rubber, which is attached to a metal window frame of the automobile door and seals the space between the window frame and the window glass. The upper edge of the window frame has a glass run mounting plate portion that protrudes outward from the passenger compartment and extends in the longitudinal direction of the vehicle. The glass run mounting plate portion has a notch that opens outward from the passenger compartment. The glass run has a glass run upper edge portion that extends in the longitudinal direction of the vehicle along the upper edge of the window frame and is attached to the glass run mounting plate portion from the outside of the passenger compartment, a glass run vertical edge portion that extends vertically along the vertical edge of the window frame, and a molded portion that connects the portion of the glass run upper edge portion closer to the center in the longitudinal direction of the vehicle than the terminal portion in the longitudinal direction of the vehicle with the upper side of the glass run vertical edge portion. The upper part of the glass run comprises an upper wall positioned on the upper surface of the glass run mounting plate portion of the upper part of the frame and extending in the front-rear direction, a lower wall positioned on the lower surface of the glass run mounting plate portion of the upper part of the frame and extending in the front-rear direction, and a vertical wall connecting the upper wall and the lower wall on the outside of the vehicle interior. The upper part of the glass run is attached to the glass run mounting plate portion by inserting the glass run mounting plate portion into the groove between the upper wall and the lower wall. The lower wall is provided with a lower wall notch that opens to the inside of the vehicle interior, and a hard member made of a material harder than the material constituting the vertical part of the glass run is detachably attached to the molded part. The hard member has a contact portion that abuts against the other edge of the lower wall notch in the vehicle front-rear direction from one side in the vehicle front-rear direction, and a locking portion that is inserted into the notch and abuts against and locks against the one edge of the notch in the vehicle front-rear direction from the other side in the vehicle front-rear direction.

[0012] In this configuration, with the glass run attached to the window frame, the upper edge of the glass run extends along the upper edge of the window frame in the vehicle's longitudinal direction, and the vertical edge of the glass run extends vertically along the vertical edge of the window frame. A rigid member is attached to the molded portion connecting the upper edge and the vertical edge of the glass run. The contact portion of the rigid member abuts against the other edge in the vehicle's longitudinal direction of the lower wall notch provided on the upper edge of the glass run, and the locking portion of the rigid member abuts against and locks against one edge in the vehicle's longitudinal direction of the notch on the glass run mounting plate. In this case, the direction in which the contact portion contacts the other edge in the vehicle's longitudinal direction of the lower wall notch provided on the upper edge of the glass run is opposite to the direction in which the locking portion contacts one edge in the vehicle's longitudinal direction of the notch on the glass run mounting plate. Therefore, when the upper edge of the glass run tries to expand in a high-temperature atmosphere, that expansion is restrained by the glass run mounting plate and the rigid member, and as a result, the protrusion of the end portion of the upper edge of the glass run is suppressed. In this case, since the contact portion of the rigid member is in direct contact with the other edge in the vehicle's longitudinal direction of the lower wall notch provided on the upper edge of the glass run, the effect of suppressing the protrusion of the end portion of the upper edge of the glass run is sufficiently enhanced.

[0013] Furthermore, since the rigid members are detachably attached to the molded section, the deterioration of moldability and the complexity of the mold mechanism that occur with insert molding do not occur, and the degree of freedom in setting the cross-sectional shape and selecting the material of the rigid members is improved.

[0014] In a second aspect of the present disclosure, the protruding wall portion of the molded portion is integrally molded with respect to the other edge of the lower wall notch in the vehicle longitudinal direction on one side in the vehicle longitudinal direction, and the contact portion contacts the other edge of the lower wall notch in the vehicle longitudinal direction from one side in the vehicle longitudinal direction via the protruding wall portion.

[0015] With this configuration, the glass run mounting plate (metal), rigid member (rigid resin: POM), and lower wall (rigid resin: talc-filled PP) can all be made of rigid material, so they hardly flex in the front-to-back direction. However, the protruding wall of the rear molded section is molded from a slightly softer material than the lower wall, so it is possible for it to flex slightly in the front-to-back direction. Therefore, assembly is easier even if there are variations in the shape and dimensions of the door, the shape and dimensions of the glass run, the shape and dimensions of the rigid member, or the fit of the door.

[0016] The protruding wall portion according to the third aspect of the present disclosure extends in the vertical direction, and the contact portion extends in the vertical direction along the protruding wall portion.

[0017] This configuration allows for a large contact area between the protruding wall portion of the molded section and the contact portion of the rigid member, thereby stabilizing the rigid member when the upper edge of the glass run attempts to expand in a high-temperature atmosphere.

[0018] The contact portion according to the fourth aspect of the present disclosure is provided on the upper part of the rigid member, and the locking portion protrudes upward from the upper part of the rigid member.

[0019] With this configuration, the vertical distance between the contact portion that abuts against the protruding wall portion of the molded section and the locking portion that abuts against the edge of the notch portion of the glass run mounting plate can be narrowed, thereby further enhancing the effect of suppressing the elongation of the upper edge of the glass run.

[0020] In a fifth aspect of the present disclosure, the molded portion is provided with a hole that penetrates in the direction of the inside and outside of the vehicle interior, and the rigid member is provided with a retaining cylinder portion that is inserted into the hole from the outside of the vehicle interior toward the inside and held therein.

[0021] With this configuration, the rigid member can be held in the molded part by inserting the rigid member's holding cylinder into the hole in the molded part. This prevents the rigid member from falling out of the molded part during transport before attachment to the window frame, thus improving workability during attachment.

[0022] In the sixth aspect of the present disclosure, a locking hole is provided in the window frame, and a locking claw portion that locks to the edge of the locking hole is provided in the holding cylinder portion.

[0023] According to this configuration, by locking the locking claw portion to the locking hole, the rigid member can be fixed to the window frame, and the rigid member becomes more stable.

[0024] In the seventh aspect of the present disclosure, the rigid member is provided with an operated portion for operating the locking claw portion in a direction to separate the locking claw portion from the edge of the locking hole.

[0025] According to this configuration, after the locking claw portion is locked to the locking hole, when removing the rigid member from the window frame, for example, when repairing, the operator can easily separate the locking claw portion from the edge of the locking hole by operating the operated portion and release the locked state.

[0026] In the eighth aspect of the present disclosure, the dimension of the locking portion in the vehicle front-rear direction is set to be shorter than the dimension of the notch portion in the vehicle front-rear direction.

[0027] According to this configuration, when inserting the locking portion of the rigid member into the notch portion of the glass run mounting plate portion, it is difficult for the locking portion to interfere with the edge of the notch portion, and the workability is improved.

Effects of the Invention

[0028] As described above, the rigid member is detachably attached to the mold forming portion, and the rigid member has an abutting portion that abuts against the other edge in the vehicle front-rear direction of the lower wall notch portion provided on the upper side portion of the glass run from one side in the vehicle front-rear direction, and a locking portion that abuts against and locks to the one edge in the vehicle front-rear direction of the notch portion formed in the glass run mounting plate portion from the other side in the vehicle front-rear direction. Therefore, without causing deterioration of the moldability of the mold forming portion, and while improving the degree of freedom in setting the cross-sectional shape and selecting the material, it is possible to suppress the protrusion of the terminal portion of the upper side portion of the glass run.

[0030] Embodiments of the present invention will be described in detail below with reference to the drawings. The following description of preferred embodiments is essentially illustrative and is not intended to limit the present invention, its applications, or its uses.

[0031] Figure 1 is a right side view of an automobile 100 to which an automobile door sealing structure according to an embodiment of the present invention is applied. The automobile 100 is provided with a front door 101 and a rear door 102 on its side. The front door 101 and the rear door 102 are attached to the body of the automobile 100 via hinges (not shown). In this description of the embodiment, the front side of the vehicle will be simply referred to as "front" and the rear side of the vehicle will be simply referred to as "rear".

[0032] (Front door configuration) As shown in Figure 2, the front door 101 comprises a door body 103 that constitutes the lower half of the front door 101, a window frame 110 that constitutes the upper half of the front door 101, a window glass G, and a glass run 20. The door body 103 comprises a metal outer panel 103a that is located on the outside of the passenger compartment and a metal inner panel that is located on the inside of the passenger compartment (not shown), with a space formed between the outer panel 103a and the inner panel.

[0033] The window frame 110 is a member that holds the peripheral edge of the window glass G and guides the window glass G in the vertical direction. The window glass G is installed so as to be able to move up and down relative to the door body 103. A lifting device (not shown) for raising and lowering the window glass G is provided inside the door body 103, and this lifting device switches between a closed state where the window glass G is raised and an open state where it is lowered.

[0034] The window frame 110 comprises a front edge portion 111, an upper edge portion 112, and a rear edge portion 113. The front edge portion 111, the upper edge portion 112, and the rear edge portion 113 hold the periphery of the window glass G in the closed state. Specifically, the front edge portion 111 protrudes upward from the front side of the beltline portion BL of the door body 103, and the rear edge portion 113 protrudes upward from the rear side of the beltline portion BL of the door body 103. The upper end of the front edge portion 111 is located below the upper end of the rear edge portion 113. The upper edge portion 112 extends in the front-rear direction, with its front end connected to the upper end of the front edge portion 111 and its rear end connected to the upper end of the rear edge portion 113. Since the upper end of the front edge 111 of the frame is located lower than the upper end of the rear edge 113 of the frame, the upper edge 112 of the frame curves gently downwards as it moves towards the front. This curved shape of the upper edge 112 of the frame corresponds to the shape of the roof of the automobile 100.

[0035] Figure 3 shows a cross-section of the upper frame portion 112 of the window frame 110 along line III-III. As shown in Figure 3, the upper frame portion 112 is composed of an upper outer panel 114 on the outside of the passenger compartment and an upper inner panel 115 on the inside of the passenger compartment. The upper outer panel 114 and the upper inner panel 115 are made of metal, such as steel plate. An upper outer side joining plate portion 114a is formed at the lower part of the upper outer panel 114, projecting downward. Similarly, an upper inner side joining plate portion 115a is formed at the lower part of the upper inner panel 115, overlapping the upper outer side joining plate portion 114a on the inside of the passenger compartment, and projecting downward. The upper outer side joining plate portion 114a and the upper inner side joining plate portion 115a are joined together.

[0036] The upper outer panel 114 has an upper outer lower plate portion 114b that protrudes outward from the vehicle interior. The upper inner panel 115 has an upper inner upper plate portion 115b that overlaps the upper outer lower plate portion 114b and protrudes outward from the vehicle interior. The upper outer lower plate portion 114b and the upper inner upper plate portion 115b are joined together to form a glass run mounting plate portion 117 for attaching the glass run 20 from the outside of the vehicle interior. The glass run mounting plate portion 117 extends in the front-rear direction. The upper inner upper plate portion 115b that constitutes the glass run mounting plate portion 117 has a cut-out portion 115d formed therein.

[0037] Furthermore, Figure 5 shows a VV line cross-section of the rear edge portion 113 of the window frame 110 shown in Figure 2. As shown in Figure 5, the rear edge portion 113 of the frame, like the upper edge portion 112 of the frame, is composed of a vertical outer panel 124 and a vertical inner panel 125. The vertical outer panel 124 and the vertical inner panel 125 are made of metal, such as steel plate.

[0038] Furthermore, as shown in Figure 11, which is a cross-section along line XI-XI in Figure 6 (described later), a vertical outer-side joining plate portion 124a is formed at the rear of the vertical outer panel 124, projecting backward. Additionally, a vertical inner-side joining plate portion 125a is formed at the rear of the vertical inner panel 125, overlapping the vertical outer-side joining plate portion 124a on the interior side of the vehicle, and projecting backward. The outer-side joining plate portion 124a and the vertical inner-side joining plate portion 125a are joined together.

[0039] Furthermore, as shown in Figure 5, the front of the vertical outer panel 124 has a vertical outer front plate portion 124b that protrudes forward. Also, the front of the vertical inner panel 125 has a vertical inner front plate portion 125b that protrudes forward and overlaps the vertical outer front plate portion 124b on the interior side of the vehicle. The vertical outer front plate portion 124b and the vertical inner front plate portion 125b are joined together.

[0040] A sash member 126 is attached to the exterior side of the vertical outer panel 124. The sash member 126 is made of metal, such as a steel plate, and extends vertically as shown in Figure 2. The lower end of the sash member 126 reaches the inside of the door body 103. As shown in Figure 5, the sash member 126 extends along the exterior surface of the vertical outer panel 124 and has a fixed plate portion 126a fixed to the front plate portion 124b of the vertical outer panel 124, a rear plate portion 126b extending from the fixed plate portion 126a toward the exterior, and a side plate portion 126c extending forward from the exterior end of the rear plate portion 126b. The fixed plate portion 126a, the rear plate portion 126b, and the side plate portion 126c of the sash member 126 form a glass run mounting groove portion 127 that opens forward.

[0041] Furthermore, Figure 11 is a cross-sectional view corresponding to the line XI-XI of the glass run 20 in Figure 6, which will be described later, and shows the state in which the glass run 20 is attached to the window frame 110. As shown in Figure 11, a locking hole 124c is formed on the upper side of the vertical outer panel 124 into which the locking claw portion 44a of the rigid member 40, which will be described later, is inserted. The locking hole 124c is formed to penetrate the vertical outer panel 124 and can be made up of a circular shape, for example. Reference numeral 130 in Figures 5, 11, and Figure 9, which will be described later (Figure 9 is a cross-sectional view showing the state in which the glass run 20 in Figure 8B, which is a cross-sectional view of the glass run 20 in Figure 6, which will be described later, attached to the window frame 110) is a garnish. The garnish 130 is a resin member that extends vertically along the outside of the passenger compartment of the rear edge portion 113 of the frame, and is provided for decorative purposes. The garnish 130 is fixed to the vertical outer panel 124 by fastening components such as clips, screws, and double-sided tape (illustrations omitted).

[0042] (Glass run configuration) The glass run 20 shown in Figure 4 is attached to the window frame 110 and is a sealing member that seals the space between the window frame 110 and the window glass G. The glass run 20 is made of at least one of resin and rubber, and is composed of hard resin (e.g., PP), thermoplastic elastomer (TPE), solid (non-foamed) rubber (e.g., EPDM), foamed rubber (e.g., EPDM), etc. These materials have a higher coefficient of thermal expansion than the metal material that makes up the window frame 110. The material of the glass run 20 can be changed depending on the part, but in this embodiment it has a coreless structure without a metal core material.

[0043] As shown in Figures 2 and 4, the glass run 20 has a front glass run portion (vertical glass run portion) 21 that extends vertically along the front frame portion 111, an upper glass run portion 22 that extends in the front-rear direction along the upper frame portion 112, and a rear glass run portion (vertical glass run portion) 23 that extends vertically along the rear frame portion 113. The front glass run portion 21 is the part that is attached to the front frame portion 111, the upper glass run portion 22 is the part that is attached to the upper frame portion 112 from the outside of the vehicle interior, and the rear glass run portion 23 is the part that is attached to the rear frame portion 113.

[0044] Furthermore, the glass run 20 includes a rear molded section 24 that connects the portion of the upper glass run portion 22 closer to the center in the front-rear direction than the rear end portion 22a to the upper part of the rear glass run portion 23. In addition, the glass run 20 also includes a front molded section 25 that connects the portion of the upper glass run portion 22 closer to the center in the front-rear direction than the front end portion 22b to the upper part of the front glass run portion 21. In Figure 4, the boundary between the rear molded section 24 and the upper glass run portion 22 and the rear glass run portion 23 is shown by a dashed line, and the boundary between the front molded section 25 and the upper glass run portion 22 and the front glass run portion 21 is also shown by a dashed line.

[0045] The front edge portion 21, the upper edge portion 22, and the rear edge portion 23 of the glass run are extruded parts (also called extruded sections) formed by extruding material from a die. On the other hand, the rear molded section 24 and the front molded section 25 are parts formed by injecting material into an opening and closing mold. When the rear molded section 24 is formed, the upper edge portion 22 and the rear edge portion 23 of the glass run can be integrated via the rear molded section 24, and when the front molded section 25 is formed, the upper edge portion 22 and the front edge portion 21 of the glass run can be integrated via the front molded section 25. Here, a thermoplastic elastomer (TPE), a type of soft resin, can be used as an example of a material that can be used for the rear molded section 24 and the front molded section 25.

[0046] The cross-sectional shape of the upper glass run portion 22 is shown in Figure 3. The upper glass run portion 22 comprises an upper wall 27 that is positioned on the upper surface of the glass run mounting plate portion 117 of the upper frame portion 112 and extends in the front-rear direction, a lower wall 28 that is positioned on the lower surface of the glass run mounting plate portion 117 of the upper frame portion 112 and extends in the front-rear direction, and a vertical wall 29 that connects the outer sides of the upper wall 27 and the lower wall 28. The upper glass run portion 22 is attached to the glass run mounting plate portion 117 by inserting the glass run mounting plate portion 117 into the groove M between the upper wall 27 and the lower wall 28. An upper projection 27a is formed on the lower surface of the upper wall 27 that engages with the cut-out portion 115d formed on the glass run mounting plate portion 117. In addition, an upper projection 27c is formed on the lower surface of the upper wall 27, on the side closer to the vehicle interior than the upper projection 27a, that elastically contacts the upper surface of the glass run mounting plate portion 117. Furthermore, a lower projection 28a is formed on the upper surface of the lower wall 28, which elastically contacts the lower surface of the glass run mounting plate portion 117.

[0047] The upper surface of the upper wall 27 has two upper lip portions 27b that project upward and elastically contact the vehicle body opening (not shown). The vertical wall 29 extends below the lower wall 28, and an outer lip portion 29a is formed at the lower end of the vertical wall 29 that elastically contacts the exterior surface of the window glass G inside the vehicle. In addition, an extension wall 30 extending downward is formed on the interior side of the lower wall 28. The extension wall 30 is formed to cover the exterior surface of the upper outer joining plate portion 114a inside the vehicle. In addition, a decorative lip portion 30b is formed on the interior surface of the extension wall 30 that extends upward from the lower end of the extension wall 30 so as to cover the interior surface of the upper inner joining plate portion 115a inside the vehicle. An inner lip portion 30a is formed on the exterior surface of the extension wall 30 inside the vehicle that contacts the interior surface of the window glass G inside the vehicle. Furthermore, as shown in Figures 8A, 8B, 8C and 9, the lower wall 28 is formed such that the lower wall notch 28b opens toward the interior surface of the vehicle.

[0048] Here, examples of materials that can be used as the upper edge 22 of the glass run shown in Figure 3 include polypropylene (PP), a type of rigid resin, for the upper wall 27, lower wall 28, and vertical wall 29, and thermoplastic elastomer (TPE), a type of flexible resin, for the outer lip portion 29a, extension wall 30, inner lip portion 30a, decorative lip portion 30b, and upper lip portion 27b. Although polypropylene (PP) is a harder material than thermoplastic elastomer (TPE), its coefficient of thermal expansion is greater than that of metal materials.

[0049] As shown in Figure 5, the rear edge portion 23 of the glass run is inserted into the glass run mounting groove portion 127 from the front and installed, and in this state the rear edge portion 23 of the glass run is fitted into the sash member 126 and does not come off. The rear edge portion 23 of the glass run has a vertical outer wall 31 located on the outside of the vehicle interior and extending in the vertical direction, a vertical inner wall 32 located on the inside of the vehicle interior and extending in the vertical direction, and a rear wall 33 connecting the rear end of the vertical outer wall 31 and the rear end of the vertical inner wall 32. The vertical outer wall 31 and the vertical inner wall 32 are held by the sash member 126. The rear edge portion of the window glass G is positioned between the vertical outer wall 31 and the vertical inner wall 32. Two vertical outer lip portions 31a formed on the vertical outer wall 31 elastically contact the exterior surface of the window glass G inside the vehicle, and a vertical inner lip portion 32a formed on the vertical inner wall 32 elastically contacts the interior surface of the window glass G inside the vehicle, thereby ensuring a sealing effect.

[0050] Here, a thermoplastic elastomer (TPE), a type of soft resin, can be used as an example of a material that can be used for the rear edge 23 and the front edge 21 of the glass run (both referred to as the vertical edge of the glass run). The material may be divided into non-foamed and foamed materials depending on the cross-sectional area. Regardless of whether it is a non-foamed or foamed material, thermoplastic elastomers (TPE) have a higher coefficient of thermal expansion than metal materials.

[0051] Furthermore, as shown in Figure 6, the upper edge portion 22 of the glass run has a vertical wall extension portion 29b that extends beyond the connection portions L1 and L2 between the rear edge portion 23 of the glass run and the rear molded portion 24 towards the terminal portion 22a. The vertical wall extension portion 29b extends along the upper edge portion 22 of the glass run to the terminal portion 22a. The outer mold wall 24e, which is a part of the rear molded portion 24 and extends downward, is integrated into the outer side of the molded portion 29b on the side facing the passenger compartment by mold molding.

[0052] Furthermore, the connection point between the vertical wall extension 29b and the outer wall 24e of the mold section is indicated by L4. Also, the connection point between the extension wall 30 and the inner lip 30a of the upper glass run section 22 and the rear mold molding section 24 is indicated by L3. Also, the connection point between the rear end portion 22a, which is the rear end of the vertical wall extension 29b of the upper glass run section 22, and the rear mold molding section 24 is indicated by L5. Furthermore, as shown in Figure 7, the connection point between the upper projection 27c and the rear mold molding section 24 is indicated by L6. Beyond the connection point L6, a shape similar to the upper projection 27c is maintained for a while, but near the rear end of the rear mold molding section 24, the inner wall 24b of the mold section is provided, which extends downward to approximately the same position as the lower end of the outer wall 24e of the mold section.

[0053] As shown in Figures 8A, 8B, and 9, a through-hole (hole portion) 24f is formed in the outer wall 24e of the mold portion, penetrating in the direction of the vehicle interior and exterior. The through-hole 24f is not circular, but has a shape close to a rectangle. The holding cylinder portion 44 of the rigid member 40, which will be described later, is inserted into the through-hole 24f. In addition, above the through-hole 24f in the outer wall 24e of the mold portion, a mounting hole 24g is formed, penetrating in the direction of the vehicle interior and exterior, for inserting the upper portion 42, which will be described later, and for attaching the rigid member 40, which will be described later.

[0054] Furthermore, as detailed in Figures 16A and 16B described later, a protruding wall portion 35 is provided in front of the mounting hole 24g in the outer wall 24e of the mold portion, projecting toward the interior of the vehicle. The protruding wall portion 35 extends in the vertical direction, and its upper end is located at the upper end of the outer wall 24e of the mold portion. The lower end of the protruding wall portion 35 is continuous with the upper end of the rear wall 33 of the rear edge portion 23 of the glass run.

[0055] A rearward protruding wall portion 36 is provided behind the mounting hole 24g in the outer wall 24e of the mold section, projecting toward the interior of the vehicle. The rearward protruding wall portion 36 extends vertically, similar to the protruding wall portion 35, and its upper end is located at the upper end of the outer wall 24e of the mold section. Behind the rearward protruding wall portion 36 in the outer wall 24e of the mold section, a first wall portion 37 and a second wall portion 38 are provided in the same manner as the rearward protruding wall portion 36. In addition, a connecting wall 39 is provided at the upper end of the outer wall 24e of the mold section, projecting toward the interior of the vehicle. The connecting wall 39 extends in the front-rear direction and connects the upper end of the rearward protruding wall portion 36, the upper end of the first wall portion 37, and the upper end of the second wall portion 38.

[0056] (Configuration of the glass run mounting plate) Figure 10 shows a cross-section along line XX in Figure 9 and includes a plan view of the area near the rear of the glass run mounting plate portion 117. As shown in Figure 10, the upper outer lower plate portion 114b of the glass run mounting plate portion 117 has a lower notch 114c formed to open outwards toward the outside of the vehicle interior. In addition, the upper inner upper plate portion 115b of the glass run mounting plate portion 117 has an upper notch 115c formed to open outwards toward the outside of the vehicle interior.

[0057] In a plan view of the glass run mounting plate portion 117, the lower notch portion 114c is positioned inside the upper notch portion 115c. Specifically, the width (dimension in the front-rear direction) of the upper notch portion 115c is set to be wider than the width (dimension in the front-rear direction) of the lower notch portion 114c, the front edge of the upper notch portion 115c is located in front of the front edge of the lower notch portion 114c, and the rear edge of the upper notch portion 115c is located behind the rear edge of the lower notch portion 114c. Furthermore, the depth (dimension in the direction of the interior-exterior direction) of the upper notch portion 115c is set to be deeper than the depth (dimension in the interior-exterior direction) of the lower notch portion 114c, and the interior edge of the upper notch portion 115c is located on the interior side of the vehicle than the interior edge of the lower notch portion 114c.

[0058] (Structure of rigid members) As shown in Figures 6 to 11, a rigid member 40 is provided on the outer wall 24e of the mold portion of the rear mold molding section 24. This rigid member 40 is made of a material harder than the material that constitutes the upper edge portion 22 of the glass run, i.e., thermoplastic elastomer (TPE). As shown in Figure 11, the rigid member 40 is covered by a garnish 130. The rigid member 40 is made by injection molding a rigid resin such as polyacetal (POM).

[0059] The material constituting the rigid member 40 may be other than POM, for example, a rigid resin material or metal. As shown in Figures 8A and 8B, the rigid member 40 is detachably attached to the outer wall 24e of the mold portion of the rear mold molding section 24. Detachable means that the rigid member 40 is not insert-molded (embedded) in the rear mold molding section 24 and is not welded to the mold molding material of the rear mold molding section 24 that constitutes the upper edge portion 22 of the glass run, so that the rigid member 40 can be easily removed or attached by hand, for example.

[0060] Since the rigid member 40 is not insert-molded (embedded) in the rear mold molding section 24, the moldability of the rear mold molding section 24 is improved, and the mold mechanism is not complicated, which is advantageous in terms of moldability and equipment. Also, the constraints on the extruded cross-sectional shape of the upper edge 22 of the glass run are reduced during die removal. Furthermore, because the rigid member 40 is not insert-molded (embedded), the degree of freedom in setting the shape of the rigid member 40 and selecting the material is improved. The improved degree of freedom in selecting the material of the rigid member 40 makes it possible to select, for example, a hard and high-strength material or a heat-sensitive material. In addition, since the rigid member 40 is detachable, if the rigid member 40 is damaged, the damaged rigid member 40 can be removed from the glass run 20 and a new rigid member 40 can be attached to the glass run 20, making it possible to reuse the glass run 20.

[0061] Figures 12 to 14 show a single rigid member 40. The rigid member 40 as a whole is a plate-like shape that is long in the vertical direction. The rigid member 40 has a lower part 41 that is long in the front-rear direction and an upper part 42 that is long in the vertical direction, and these are integrally molded. Furthermore, the length of the upper part 42 in the front-rear direction of the vehicle is shorter than the length of the lower part 41 in the front-rear direction of the vehicle. As shown in Figure 8B, the upper part 42 is continuous with the upper edge of the lower part 41 and is located inside the vehicle interior than the upper edge of the lower part 41. Also, when the upper part 42 is viewed from the front-rear direction, it is inclined so that it is located inside the vehicle interior as it approaches the upper end of the upper part 42.

[0062] Furthermore, as shown in Figures 13 and 14, a front projection 42b is formed at the front end of the upper portion 42, projecting inward into the passenger compartment and extending vertically. The front surface of the front projection 42b is also part of the front surface of the upper portion 42, and as shown in Figure 16, which will be described in detail later, the upper part of the front surface of the front projection 42b is a contact portion 42a that abuts against the protruding wall portion 35 from the rear. As shown in Figures 16A and 16B, when the rigid member 40 is attached to the outer wall 24e of the mold portion, the contact portion 42a extends vertically along the protruding wall portion 35. This ensures a wide contact area between the contact portion 42a and the protruding wall portion 35. Furthermore, as shown in Figures 13 and 14, a rear projection 42c is formed at the rear end of the upper portion 42, projecting inward into the passenger compartment and extending vertically. The dimensions of the upper portion 42 are set such that the rear end of the upper portion 42 is positioned forward of the rearward protruding wall portion 36 of the outer wall 24e of the mold portion.

[0063] Furthermore, a locking portion 43 is provided on the upper portion 42. The locking portion 43 is columnar or pin-shaped and protrudes upward from the upper part of the upper portion 42. As shown in Figure 10, the locking portion 43 is inserted into the lower notch 114c and the upper notch 115c from the outside of the vehicle interior. When the locking portion 43 is inserted into the lower notch 114c, it contacts and locks against the rear edge 114cb of the lower notch 114c from the front (the other side in the vehicle's longitudinal direction).

[0064] Here, the front-to-back dimension of the locking portion 43 is set to be shorter than the front-to-back dimension of the lower notch portion 114c. When inserted into the lower notch portion 114c, the rear surface 43b of the locking portion 43 abuts against the rear edge portion 114cb of the lower notch portion 114c, while the front surface 43f of the locking portion 43 is set back from the front edge portion 114cf of the lower notch portion 114c. Furthermore, since the upper notch portion 115c is wider than the lower notch portion 114c, there is no interference with the locking portion 43.

[0065] Furthermore, as shown in Figures 13 and 14, a rib 42d is formed on the interior side of the upper part 42. The upper part of the rib 42d is connected to the lower part of the locking part 43. The rib 42d extends in the vertical direction, and its protrusion height decreases as it goes downwards. By setting the rib 42d, the joint strength of the locking part 43 to the main body, the upper part 42, can be improved, and even if the locking part 43 is subjected to a large force, it is prevented from breaking or being damaged relative to the upper part 42.

[0066] Furthermore, a lower projection 41a is formed at the front end of the lower portion 41, which protrudes inward towards the passenger compartment and extends vertically. In addition, a retaining cylinder portion 44 is provided in the middle of the lower portion 41 in the front-rear direction. The retaining cylinder portion 44 protrudes from the lower portion 41 toward the passenger compartment, and as shown in Figures 8A and 8B, the rigid member 40 is held relative to the glass run rear mold molding portion 24 by being inserted from the outside to the inside of the through hole 24f in the outer wall 24e of the mold portion. The cross-sectional shape of the retaining cylinder portion 44 corresponds to the shape of the through hole 24f, and the outer circumferential surface of the retaining cylinder portion 44 contacts the inner circumferential surface of the through hole 24f, and the frictional force between the two makes it difficult for the retaining cylinder portion 44 to come out of the through hole 24f. Alternatively, the retaining cylinder portion 44 may be press-fitted into the through hole 24f.

[0067] As shown in Figures 9 and 11, the position of the retaining cylinder portion 44 corresponds approximately to the position of the locking hole 124c of the vertical outer panel 124. As shown in Figure 11, the retaining cylinder portion 44 is provided with locking claw portions 44a, 44a that engage with the edge of the locking hole 124c. That is, as shown in Figures 13 and 14, a support portion 45 that supports the locking claw portions 44a, 44a is formed at the end of the retaining cylinder portion 44 on the vehicle interior side so as to protrude toward the vehicle interior. The support portion 45 has an upper protruding wall 45a that protrudes from the upper part of the retaining cylinder portion 44 toward the interior of the vehicle, and a lower protruding wall 45b that protrudes from the lower part of the retaining cylinder portion 44 toward the interior of the vehicle. Furthermore, it has a pair of connecting portions 45c, 45c, one connecting portion 45c in the front-rear direction that connects the front end of the upper protruding wall 45a and the front end of the lower protruding wall 45b, and the other connecting portion 45c in the front-rear direction that connects the rear end of the upper protruding wall 45a and the rear end of the lower protruding wall 45b, and the overall shape is cylindrical. As shown in Figures 13, 14, and Figure 15A, which is a cross-section of line AA in Figure 14, the pair of connecting portions 45c, 45c are arranged with a gap S1 in the front-rear direction, and one connecting portion 45c can bend and deform in a direction toward approaching the other connecting portion 45c due to the elasticity of the resin.

[0068] The base end of one locking claw portion 44a is connected to one connecting portion 45c, and the locking claw portion 44a is positioned to protrude from the connecting portion 45c in one direction in the front-rear direction. Similarly, the base end of the other locking claw portion 44a is connected to the other connecting portion 45c, and the locking claw portion 44a is positioned to protrude from the other connecting portion 45c in the other direction in the front-rear direction. As shown in Figures 14 and 15A, a gap S2 is created between the two locking claw portions 44a, 44a that is approximately the same as the gap S1 between the connecting portions 45c, 45c.

[0069] Furthermore, as shown in Figures 13 and 15A, although both locking claws 44a, 44a are connected to a pair of connecting parts 45c, 45c of the retaining cylinder part 44 at their base ends, the opposite side of the base end is not connected to the retaining cylinder part 44 with a gap S3 provided. As a result, both locking claws 44a, 44a are more susceptible to bending deformation.

[0070] Furthermore, as shown in Figure 15A, the outer ends of the locking claws 44a, 44a are provided with operable parts 44b, 44b for operating the locking claws 44a, 44a away from the edge of the locking hole 124c. The operable parts 44b, 44b are arranged within the retaining cylinder 44 with a gap S4 between them in the front-rear direction. The operable parts 44b, 44b are not connected to the retaining cylinder 44, similar to the locking claws 44a, 44a. By moving the operable parts 44b, 44b toward each other, the distance between the locking claws 44a, 44a is narrowed, making it possible to move them away from the edge of the locking hole 124c.

[0071] (Installation of rigid components) When attaching the rigid member 40 to the outer wall 24e of the mold, if the retaining cylinder portion 44 is attached first, the upper portion 42 cannot be attached, so the upper portion 42 is attached first. First, as shown in Figure 8A, the rigid member 40 is placed on its side with the support portion 45 facing downwards and the locking portion 43 facing inwards towards the vehicle interior, and the locking portion 43 is inserted into the mounting hole 24g until the upper end 41b of the lower portion contacts the outer surface of the outer wall 24e of the mold. At this time, the width of the mounting hole 24g in the vehicle longitudinal direction is set to be approximately equal to the width of the upper portion 42 in the vehicle longitudinal direction, so the lower portion 41, whose width in the vehicle longitudinal direction is set to be larger than that of the upper portion 42, cannot be inserted into the mounting hole 24g.

[0072] Next, the rigid member 40 is rotated from the horizontal position shown in Figure 8A to the tilted position shown in Figure 8B. More specifically, as shown in Figure 8A, the rotation is centered around the connection between the upper part 42 and the lower part 41, and the lower part 41 is rotated in the F1 direction (outside the vehicle interior) so that the upper end surface 41b of the lower part 41 is below the upper surface of the mounting hole 24g of the outer wall 24e of the mold part, the upper protruding wall 45a of the retaining cylinder part 44 of the lower part 41 is rotated in the F2 direction (inside the vehicle interior), and the locking part 43 of the upper part 42 is rotated in the F3 direction (outside the vehicle interior) to reach the state shown in Figure 8B. Furthermore, the rigid member 40 is rotated from the tilted state shown in Figure 8B to the upright state shown in Figure 8C. More specifically, as shown in Figure 8B, the lower part 41 is rotated in the F4 direction (outside the vehicle interior) with the vicinity of the connection between the upper part 42 and the lower part 41 as the rotation center, so that the upper end surface 41b of the lower part 41 is directly below the upper surface of the mounting hole 24g of the outer wall 24e of the mold part, the upper protruding wall 45a of the retaining cylinder part 44 of the lower part 41 is rotated in the F5 direction (inside the vehicle interior) and inserted into the through hole 24f, and the locking part 43 of the upper part 42 is rotated in the F6 direction (outside the vehicle interior) to the state shown in Figure 8C, thereby completing the installation.

[0073] In this state, the rigid member 40 is held in the rear mold molding section 24, which prevents the rigid member 40 from falling off the rear mold molding section 24 before the glass run 20 is attached to the window frame 110.

[0074] More specifically, in addition to holding the retaining cylinder portion 44 in the through hole 24f, the upper end surface 41b of the lower portion 41 is positioned directly below and in contact with the upper surface of the mounting hole 24g of the outer wall 24e of the mold portion, and the outer surface of the upper portion 42 near the upper end surface 41b of the lower portion 41 is in contact with the inner surface of the outer wall 24e of the mold portion, thereby preventing the hard member 40 from falling out of the rear mold molding portion 24.

[0075] Furthermore, when the rigid member 40 is attached to the outer wall 24e of the mold section, as shown in Figure 6, the outer surface of the lower part 41 faces outwards from the vehicle interior, while, as shown in Figure 7, the tip of the retaining cylinder part 44, the locking claw part 44a, and the support part 45 are positioned on the vehicle interior side of the outer wall 24e of the mold section. Also, the outer surface of the upper part 42 is positioned to face inwards from the vehicle interior.

[0076] Furthermore, as shown in Figures 8C and 9, the lower wall 28 of the upper edge 22 of the glass run has a lower wall notch 28b formed therein, which is cut out on the vehicle interior side and opens to the interior. However, the dimension of the locking portion 43 shown in Figure 10 in the vehicle longitudinal direction is set to be shorter than the notch dimension of the lower wall notch 28b in the vehicle longitudinal direction.

[0077] Furthermore, as shown in Figures 8C and 9, the locking portion 43 is positioned to protrude upward from the upper surface of the remaining, uncut lower wall extension portion 28c.

[0078] (Installation of glass run) After attaching the rigid member 40 to the glass run 20, the glass run 20 is attached to the window frame 110. As shown in Figure 9, when attaching the upper edge portion 22 of the glass run to the glass run mounting plate portion 117, the locking portion 43 of the rigid member 40 is inserted into the lower notch portion 114c and the upper notch portion 115c from the outside of the vehicle interior. Also, as shown in Figure 10, when inserting the locking portion 43 into the lower notch portion 114c, the front-to-rear dimension of the locking portion 43 is set to be shorter than the front-to-rear dimension of the lower notch portion 114c, so that the locking portion 43 can be easily inserted into the lower notch portion 114c while absorbing some assembly errors.

[0079] When the locking portion 43 is inserted into the lower notch 114c, the rear surface 43b of the locking portion 43 abuts against the rear edge 114cb of the lower notch 114c. Also, as shown in Figure 11, the locking claws 44a, 44a are inserted into the locking holes 124c of the vertical outer panel 124. When inserting the locking claws 44a, 44a into the locking holes 124c, as shown in Figures 13, 14 and 15A, the locking claws 44a, 44a and the connecting portions 45c, 45c are easily elastically deformed by the elasticity of the resin and the gap S1 to S4. After insertion, the shape is restored, and as shown in Figure 11, the locking claws 44a, 44a lock onto the periphery of the locking hole 124c from the inside of the vehicle.

[0080] When the glass run 20 is attached to the window frame 110, as shown in Figures 16A and 10, the contact portion 42a of the rigid member 40 contacts the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run, and the rear surface 43b of the locking portion 43 of the rigid member 40 contacts and locks with one edge 114cb in the vehicle longitudinal direction of the lower notch 114c of the glass run mounting plate 117. Here, in Figure 10, the positional relationship between the lower wall notch 28b and the other edge (front edge of the lower wall notch) 28bf in the vehicle longitudinal direction is shown by a dashed line.

[0081] At this time, the direction in which the contact portion 42a contacts the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run is opposite to the direction in which the rear surface 43b of the locking portion 43 contacts one edge 114cb in the vehicle longitudinal direction of the lower notch 114c. Therefore, when the upper edge 22 of the glass run tries to expand in a high-temperature atmosphere, that expansion is restrained by the glass run mounting plate portion 117 and the rigid member 40, and as a result, the outward protrusion of the terminal portion 22a of the upper edge 22 of the glass run is suppressed. At this time, since the contact portion 42b of the rigid member 40 is in direct contact with the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run, the effect of suppressing the outward protrusion of the terminal portion 22a of the upper edge 22 of the glass run is sufficiently enhanced.

[0082] Furthermore, as shown in Figure 16A, instead of the contact portion 42a of the rigid member 40 directly contacting the other edge 28bf in the vehicle's longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run, the structure shown below may be used.

[0083] In other words, as shown in Figure 7, of the two upper lips 27b, the inner upper lip 27b1 is left uncut until just before the protruding wall portion 35, and as shown in Figure 16B, the lower wall 28 is also left uncut until just before the protruding wall portion 35. In other words, the contact portion 42a of the rigid member 40 is positioned to contact the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run, via the protruding wall portion 35 of the rear molded portion 24.

[0084] Here, the glass run mounting plate 117 (metal), the rigid member 40 (rigid resin: POM), and the lower wall 28 (rigid resin: talc-filled PP) are all rigid members and hardly deform by bending in the front-to-back direction. However, the protruding wall 35 of the rear molded part 24 is molded from a slightly softer material than the lower wall 28, and is therefore capable of slight bending deformation in the front-to-back direction.

[0085] Therefore, even if variations occur in the shape and dimensions of the front door 101, the glass run 20, the rigid member 40, or the fit of the front door 101, assembly is made easier.

[0086] Furthermore, as shown in Figures 16A and 16B, the contact portion 42a of the rigid member 40 may be made to contact (zero contact) with one edge 114cb in the vehicle longitudinal direction of the lower notch 114c of the glass run mounting plate portion 117, the rear surface 43b of the locking portion 43 of the rigid member 40, the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge portion 22 of the glass run, or the rear surface 35b of the protruding wall portion 35 of the rear molded portion 24. Considering variations in the shape and dimensions of part 1, the glass run 20, the rigid member 40, and the fit of the front door 101, a small gap may be set between the contact portion 42a of the rigid member 40 and the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided on the upper edge 22 of the glass run, or the rear side surface 35b of the protruding wall 35 of the rear molded portion 24, to further facilitate assembly (illustrations omitted). It is preferable to set the small gap to be smaller than the allowable displacement (movement) dimension of the upper edge 22 of the glass run.

[0087] (Removal of rigid components) When removing the glass run 20 from the window frame 110, it is necessary to remove the locking claws 44a, 44a of the rigid member 40 from the locking holes 124c. In this embodiment, first, the garnish 130 is removed from the state shown in Figure 11. Next, the tip of a tool such as needle-nose pliers is inserted into the retaining cylinder portion 44 from the outside of the vehicle interior, and the operated portions 44b, 44b are gripped in a direction that brings them closer together, so that the locking claw portions 44a, 44a separate from the edge of the locking hole 124c and the locking state of the locking claw portions 44a, 44a is released, and the locking claw portions 44a, 44a can be removed from the locking holes 124c.

[0088] (Effects of the embodiment) As explained above, since the rigid member 40 is detachably attached to the rear mold molding section 24, it is possible to improve the freedom of setting the cross-sectional shape and selecting the material of the upper glass run portion 22 without causing deterioration of the moldability of the rear mold molding section 24. Furthermore, the contact portion 42a of the rigid member 40 contacts the other edge 28bf in the vehicle longitudinal direction of the lower wall notch 28b provided in the lower wall 28 of the upper glass run portion 22 from the rear, and the locking portion 43 of the rigid member 40 contacts and locks the other edge 114cb in the vehicle longitudinal direction of the lower notch 114c of the glass run mounting plate portion 117 from the other edge in the vehicle longitudinal direction, so that the end portion 22a of the upper glass run portion 22 can be prevented from protruding in one direction (rear) in the vehicle longitudinal direction.

[0089] (Modified version of the embodiment) As shown in Figures 9 and 7, the upper plate portion 24a of the rear molded portion 24 is connected to the interior side of the notched inner end 27e of the upper plate portion 27, and an inner plate portion 24b is provided that extends downward from the interior side end of the upper plate portion 24a. Also, as shown in Figures 7, 16A and 16B, the front end 24b1 of the inner plate portion 24b is positioned between the rear wall portion 36 and the first wall portion 37, closer to the first wall portion 37, and after the glass run 20 is attached to the front door 101, the rear end 117e of the glass run mounting plate portion 117 is positioned behind the second wall portion 38.

[0090] In this positional relationship, when attaching the rear molded glass run section 24 to the glass run mounting plate section 117, the rear end 117e of the glass run mounting plate section 117 is inserted from in front of the front end 24b1 of the inner plate section 24b of the rear molded glass run section 24. Therefore, the person installing the glass run 20 must take care to ensure that the locking portion 43 does not interfere with the glass run mounting plate section 117, and the installation will be carried out under conditions where the upper notch 115 and the lower notch 114 and the locking portion 43 of the rigid member 40 cannot be directly seen.

[0091] For example, in Figure 17, when the glass run 20 is attached to the window frame 110, the locking portion 43 of the rigid member 40 is engaged with the recess 124d of the vertical outer panel 124. That is, the upper part of the vertical outer panel 124 is composed of an inclined surface 124d1 that slopes inward towards the interior of the vehicle as it goes upward, and a curved surface 124d2 that is connected to the upper end of the inclined surface 124d1 and curves outward towards the exterior of the vehicle as it goes upward, forming a recess 124d that is deeply recessed towards the interior of the vehicle.

[0092] On the other hand, when attaching the glass run 20 to the window frame 110, the rigid member 40 is held in the rear molded portion 24 of the glass run 20, and the rigid member 40 and the glass run 20 are attached together. As mentioned above, the person installing the glass run 20 cannot directly see the upper notch 115 and the lower notch 114 and the locking portion 43 of the rigid member 40. As a result, if the locking portion 43 ends up under the curved surface 124d2 above the recess 124d, it can be difficult to confirm whether the rigid member 40 has been assembled in the correct position (shown in Figure 9).

[0093] Here, the modified form shown in Figures 18 and 19 is intended to resolve this issue, and an inner projection 42e is formed on the interior surface of the upper part 42. The inner projection 42e protrudes inward into the vehicle interior and is composed of a rib that extends in the vertical direction, and the amount of protrusion inward into the vehicle interior is set to be larger compared to the rib 42d, contact part 42b, and rear projection upper part 42c shown in Figure 13.

[0094] Furthermore, the inner projection 42e is located in the middle of the upper portion 42 in the front-rear direction, away from the contact portion 42b and away from the rear projection 42c.

[0095] Furthermore, the protrusion dimension (dimension in the direction of the interior and exterior of the vehicle) of the inner protrusion 42e is set to be largest in the middle of the vertical direction, and decreases as it approaches the upper end of the inner protrusion 42e and as it approaches the lower end of the inner protrusion 42e. In addition, chamfered portions 43a are formed on the upper part of the interior side surface of the locking portion 43, the upper part of the exterior side surface, the upper part of the front side surface, and the upper part of the rear side surface.

[0096] Because the rigid member 40 has an inner protrusion 42e, when it is attached to the window frame 110, the inner protrusion 42e comes into contact with the inclined surface 124d1 of the vertical outer panel 124. As a result, the orientation of the rigid member 40 is controlled to rotate toward the outside of the vehicle interior, so that regardless of the assembly method, and even if it is difficult to directly visually confirm, the locking portion 43 is less likely to get stuck under the curved surface 124d2 that constitutes the recess 124d of the vertical outer panel 124, and the rigid member 40 can be assembled in the correct position.

[0097] Furthermore, since a chamfered portion 43a is formed on the upper part of the locking portion 43, when inserting the locking portion 43 into the lower notch portion 114c, the upper part of the locking portion 43 is less likely to catch on the edge of the lower notch portion 114c. Therefore, the locking portion 43 can be reliably inserted into the lower notch portion 114c and reliably locked onto the edge of the lower notch portion 114c.

[0098] The embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. Furthermore, any modifications or changes that fall within the equivalent scope of the claims are all within the scope of the present invention.

[0099] In this embodiment, the case in which the present invention is applied to the front door 101 has been described, but it is not limited to this, and the present invention can also be applied to the rear door 102. When applied to the rear door 102, although not shown, the rigid member 40 can be provided on the glass run so that it is located on the front side of the window frame. This prevents the front end portion of the upper edge of the glass run from protruding forward. [Industrial applicability]
