Description

Technical Field

[0001] The present disclosure relates to a sealing structure provided on a vehicle door.

Background Art

[0002] Some vehicle 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 Document 1).

[0003] The glass run of Patent Document 1 is configured to be attached to the window frame from the outside of the vehicle compartment. That is, a glass run mounting plate portion that protrudes outside the vehicle compartment and extends in the vehicle longitudinal direction is formed on the upper side portion of the window frame. On the other hand, the upper side portion of the glass run includes an upper wall that is disposed on the upper surface of the glass run mounting plate portion and extends in the longitudinal direction, a lower wall that is disposed on the lower surface of the glass run mounting plate portion and extends in the longitudinal direction, and a vertical wall that connects the outside of the vehicle compartment of the upper wall and the lower wall. An insertion groove into which the glass run mounting plate portion can be inserted is formed between the upper wall and the lower wall. Further, the upper side portion of the glass run and the vertical side portion of the glass run are connected by a molding portion, and a hard member is attached to this molding portion.

[0004] In Patent Document 1, the contact portion provided on the hard member contacts the edge portion of the lower wall notch portion provided on the upper side portion of the glass run, and the locking portion provided on the hard member contacts the edge portion of the notch portion of the glass run mounting plate portion.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Incidentally, in the glass run described in Patent Document 1, the contact portion of the rigid member contacts the edge of the notch in the lower wall of the upper edge of the glass run, and the locking portion of the rigid member contacts the edge of the notch in the glass run mounting plate and locks in place. As a result, 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 can be suppressed.

[0007] However, behind the rigid member, a gap is created between the upper wall of the upper edge of the glass run and the upper surface of the glass run mounting plate. Therefore, if a downward load is applied to the rear end of the upper edge of the glass run, for example, there is a concern that the end portion of the upper edge of the glass run will deform downward, resulting in an unsightly appearance.

[0008] This disclosure is made in view of the above points, and its purpose is to suppress downward deformation of the terminal portion of the upper edge of the glass run and to improve its appearance. [Means for solving the problem]

[0009] To achieve the above objective, one aspect of the present disclosure may provide a sealing structure for an automobile door, which is attached to a metal window frame of the automobile door and includes a glass run made of at least one of resin and rubber that seals the space between the window frame and the window glass.

[0010] 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 that is 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 glass run upper edge portion has an upper wall that is positioned on the upper surface of the glass run mounting plate portion of the upper edge of the frame and extends in the longitudinal direction, a lower wall that is positioned on the lower surface of the glass run mounting plate portion of the upper edge of the frame and extends in the longitudinal direction, and a vertical wall that connects the outer sides of the upper wall and the lower wall. The upper edge of the glass run is attached to the glass run mounting plate by inserting the groove between the upper wall and the lower wall into the glass run mounting plate, and the lower wall is provided with a lower wall notch that opens to the inside of the vehicle. A hard member made of a material harder than the material constituting the vertical edge 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's longitudinal direction from one side in the vehicle's longitudinal direction, and a locking portion that is inserted into the notch and abuts against and locks against the other edge of the notch in the vehicle's longitudinal direction from the other side in the vehicle's longitudinal direction. A spacer portion is provided that protrudes from the upper part of the locking portion in one side in the vehicle's longitudinal direction and is inserted between the upper surface of the glass run mounting plate and the lower surface of the upper wall of the upper edge of the glass run.

[0011] 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.

[0012] 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.

[0013] Furthermore, by inserting the rigid spacer portion between the upper surface of the glass run mounting plate portion of the window frame and the lower surface of the upper wall of the upper edge portion of the glass run, it is possible to prevent the end portion of the upper edge portion of the glass run from deforming downward when a downward load is applied to one side of the upper edge portion of the glass run in the vehicle's longitudinal direction.

[0014] The interior side of the spacer portion may be provided with a guide portion extending inward to guide the spacer portion to the upper surface of the glass run mounting plate portion. The guide portion may also be provided further inward than the locking portion. This makes it less likely for incorrect assembly to occur, as the spacer portion is guided to the upper surface of the glass run mounting plate portion by the guide portion when assembling the upper edge of the glass run portion to the upper edge of the frame.

[0015] A chamfered portion may be provided on the outer side of the spacer portion to shorten the dimension of the spacer portion in the vehicle width direction. Furthermore, a notch may be provided on the rigid member below the locking portion and on the other side in the vehicle longitudinal direction of the locking portion, such that the dimension of the upper part of the rigid member in the vehicle longitudinal direction is shorter than the dimension of the lower part of the rigid member in the vehicle longitudinal direction. This improves the ease of assembly when assembling the rigid member to the upper edge of the glass run.

[0016] Furthermore, the other side of the locking portion in the vehicle's longitudinal direction and the other side of the contact portion in the vehicle's longitudinal direction may be made substantially the same plane in the vehicle's longitudinal direction.

[0017] This makes it possible to reduce the gap between one edge of the lower wall cutout in the vehicle's front-to-rear direction and the other side of the locking portion in the vehicle's front-to-rear direction when attaching the upper part of the glass run to the upper part of the frame, thereby making incorrect assembly less likely.

[0018] The protruding wall portion of the molded portion may be integrally molded with the other edge of the lower wall notch in the vehicle's longitudinal direction, and the contact portion may contact the protruding wall portion.

[0019] With this configuration, the glass run mounting plate (metal), the rigid member (rigid resin: POM), and the lower wall (rigid resin: talc-filled PP) can all be made of rigid members, There is almost no bending deformation in the front-rear direction. However, since the protruding wall portion of the rear-side molded portion is molded from a material slightly softer than the lower wall, it can be slightly bent and deformed in the front-rear direction. Therefore, even when there are variations in the shape and dimensions of the door, variations in the shape and dimensions of the glass run, variations in the shape and dimensions of the rigid member, variations in the door mounting, etc., it is easier to assemble.

Advantages of the Invention

[0020] As described above, since the spacer portion inserted between the upper surface of the glass run mounting plate portion of the window frame and the lower surface of the upper wall of the upper side portion of the glass run is provided with a rigid member, downward deformation of the terminal portion of the upper side portion of the glass run can be suppressed, and the appearance can be improved.

[Modes for carrying out the invention]

[0022] 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.

[0023] 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." Also, the interior side of the vehicle will be referred to as the interior side, and the exterior side of the vehicle will be referred to as the exterior side.

[0024] (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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 vertical outer-side joining plate portion 124a and the vertical inner-side joining plate portion 125a are joined together.

[0031] 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.

[0032] 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.

[0033] 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 8F, 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 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).

[0034] (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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 to 8F and Figure 9, the lower wall 28 is formed such that the lower wall notch 28b opens toward the interior surface of the vehicle.

[0040] 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.

[0041] 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, the vertical inner wall 32 and the rear wall 33 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.

[0042] 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.

[0043] 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.

[0044] 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 extended 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, 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.

[0045] As shown in Figures 8A to 8F and Figure 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.

[0046] Furthermore, as shown in Figure 16, which will be described in detail 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.

[0047] 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.

[0048] (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.

[0049] 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.

[0050] (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).

[0051] 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 to 8F, the rigid member 40 is detachably attached to the outer wall 24e of the mold part 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 22 of the glass run, so that the rigid member 40 can be easily removed or attached by hand, for example.

[0052] 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.

[0053] Figures 12 to 14 show a single rigid member 40. The rigid member 40 comprises a lower portion 41 that is long in the front-rear direction and an upper portion 42 that is long in the up-down direction, and these are integrally molded. As shown in Figures 12 and 13, the upper portion 42 is continuous with the upper edge of the lower portion 41 and is located on the interior side of the vehicle interior than the upper edge of the lower portion 41. Also, as shown in Figure 9, when the upper portion 42 is viewed from the front-rear direction, it is inclined so that it is located on the interior side of the vehicle interior as it approaches the upper end of the upper portion 42.

[0054] 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 will be described in detail later, as shown in Figure 16, the upper portion 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 Figure 16, 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. Also, as shown in Figures 13, 14 and 16, 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.

[0055] 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).

[0056] 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 in the front-to-back direction than the lower notch portion 114c, there is no interference with the locking portion 43.

[0057] Furthermore, as shown in Figures 12 to 14, a lower projection 41a is formed at the front end of the lower portion 41, extending vertically and projecting inward towards the passenger compartment. A retaining cylinder portion 44 is also provided in the middle of the lower portion 41 in the front-rear direction. The retaining cylinder portion 44 projects inward from the lower portion 41 towards the passenger compartment, and as shown in Figures 8E and 8F, it is inserted from the outside to the inside of the through hole 24f in the outer wall 24e of the mold portion, thereby holding the hard member 40 relative to the rear mold molding portion 24 of the glass run. 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. 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Furthermore, as shown in Figures 11 and 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.

[0062] Furthermore, as shown in Figures 12 to 14, the rigid member 40 is provided with a spacer portion 46 that protrudes from the upper part of the locking portion 43 in one direction in the vehicle's longitudinal direction and is inserted between the upper surface of the glass run mounting plate portion 117 and the lower surface of the upper wall 27 of the glass run upper edge portion 22. The spacer portion 46 is plate-shaped and extends in both the vehicle's longitudinal direction and the vehicle's width direction. By being inserted between the upper surface of the glass run mounting plate portion 117 and the lower surface of the upper wall 27 of the glass run upper edge portion 22, it suppresses downward deformation of the end portion of the glass run upper edge portion 22.

[0063] On the interior side of the spacer portion 46, a guide portion 47 is provided that extends inward to guide the spacer portion 46 to the upper surface of the glass run mounting plate portion 117. The guide portion 47 is provided in the front portion of the spacer portion 46, further inward than the locking portion 43.

[0064] Chamfered portions 46a are provided on the outer sides of the vehicle opposite to the vehicle at the vehicle longitudinal position where the guide portion 47 is provided, shortening the widthwise dimension of the spacer portion 46. Furthermore, on the rigid member 40, below the locking portion 43 and on the other side in the vehicle longitudinal direction from the locking portion 43, there is a notch 40a on the other side that shortens the widthwise dimension of the upper portion of the rigid member 40's upper portion 42 to less than the widthwise dimension of the lower portion of the rigid member 40's upper portion 42. Moreover, the other side of the vehicle longitudinal direction of the locking portion 43 and the other side of the vehicle longitudinal direction of the contact portion 42a are made to be substantially the same plane in the vehicle longitudinal direction.

[0065] Furthermore, as shown in Figure 16, the rear side of the protruding wall portion 35 is provided with an extension portion 35a that extends rearward. The extension portion 35a is molded to extend rearward along the lower surface of the lower wall 28 and upward along the rear end edge 28bf of the lower wall notch portion 28b. The rear side surface 35b of the extension portion 35a abuts against the upper portion 42 of the rigid member 40 from the front of the vehicle.

[0066] Furthermore, the state in which the glass run 20 with the rigid member 40 attached is mounted on the glass run mounting plate 117 is shown in Figures 9 and 16. More specifically, the upper surface of the rigid member 40 abuts against the lower surface of the upper wall 27 of the glass run 20 over almost the entire area of ​​the spacer portion 46 in the vehicle's longitudinal direction.

[0067] On the other hand, the lower surface of the spacer portion 46 of the rigid member 40 is configured to abut against the upper surface of the glass run mounting plate portion 117 near the end on one side in the vehicle's longitudinal direction, at least near the end on one side in the vehicle's longitudinal direction.

[0068] At least the end of the spacer portion 46 of the rigid member 40 on one side in the vehicle's longitudinal direction is positioned between members that are harder than the material constituting the vertical edge of the glass run, both on the upper and lower sides, and the dimensions are set so that they are in direct contact with each other. Therefore, when a downward load is applied to the upper edge 22 of the glass run in one direction in the vehicle's longitudinal direction, the terminal portion 22a of the upper edge 22 of the glass run is not displaced further downward.

[0069] Furthermore, the dimensions and thickness of the spacer portion 46 in the vehicle's vertical direction may be made slightly smaller in areas other than near one end in the vehicle's longitudinal direction, specifically near the locking portion 43, than in areas near one end in the vehicle's longitudinal direction.

[0070] By doing so, the locking portion 43 becomes easier to attach to the notch 114c of the glass run mounting plate portion 117, and the setting range of the thickened portion of the spacer portion 46 can be shortened, so that the moldability of the spacer portion 46 is not impaired.

[0071] Alternatively, multiple rows of grooves with an upper opening may be provided on the upper surface of the thickened portion of the spacer portion 46 to ensure the moldability of the thickened portion of the spacer portion 46.

[0072] (Installation of rigid components) Figure 8A also shows the mounting hole 24g as seen from the outside of the vehicle interior, and the dimension L10 of the mounting hole 24g in the vehicle longitudinal direction is set to be less than half of the dimension L13 of the spacer portion 46 in the vehicle longitudinal direction. In contrast, the dimension L14 of the spacer portion 46 in the vehicle width direction shown in Figure 8C is set to be less than or equal to the dimension L10 of the mounting hole 24g in the vehicle longitudinal direction by providing a chamfered portion 46a on the spacer portion 46, as shown in Figure 10. Furthermore, when attaching the rigid member 40 to the outer wall 24e of the mold portion, if the retaining cylinder portion 44 is attached first, the upper portion 42 cannot be attached, so the upper portion 42 is attached first.

[0073] Therefore, as shown in Figure 8A, when attaching the rigid member 40 to the outer wall 24e of the mold, first, with the longitudinal direction (vehicle front-rear direction) of the spacer portion 46 aligned with the vehicle width direction of the outer wall 24e of the mold, the spacer portion 46 is moved in the direction of arrow F1 and inserted into the mounting hole 24g from the outside of the vehicle. Then, the rigid member 40 is rotated in the directions of arrows F2 and F3 so that the base end of the spacer portion 46 is positioned above the tip. As a result, the rigid member 40 is tilted as shown in Figure 8B.

[0074] Subsequently, the rigid member 40 is rotated approximately 90° in the directions of arrows F4 and F5 so that the tip of the spacer portion 46 faces backward. At this time, because the spacer portion 46 is provided with a chamfered portion 46a, the width dimension of the base end portion of the spacer portion 46 in the vehicle width direction is shortened, making it easy to rotate the rigid member 40 in the directions of arrows F4 and F5.

[0075] Furthermore, when rotating the rigid member 40 by approximately 90°, rotating it at the smaller locking portion 43 allows for easy rotation, but on the other hand, there is a possibility that the joint between the locking portion 43 and the spacer portion 46, which is integrated with the upper portion of the locking portion 43, may be damaged. Conversely, rotating it by approximately 90° at the upper portion 42 reduces the likelihood of the rigid member 40 breaking. However, although the front-to-back dimension L15 of the upper portion 42 is equivalent to the front-to-back dimension L1 of the mounting hole 24g, it is more than twice as large as the vertical dimension L12 of the mounting hole 24g (shown in Figure 8A). Therefore, it is necessary to widen the mounting hole 24g while rotating, which significantly increases the insertion time. Therefore, by providing a notch 40a on the other side of the upper and front side of the upper part 42 so that the dimension L16 is the same as or slightly larger (1.5 times or less) than the dimension L12, and by rotating the part in which the other side notch 40a is provided by approximately 90°, the joint between the locking part 43 and the spacer part 46 is less likely to be damaged, and the above-mentioned rotation can be completed in a short time.

[0076] Subsequently, as shown in Figure 8C, the rigid member 40 is moved in the direction of arrow F6, and as shown in Figure 8D, the upper end surface 41b of the lower part 41 of the rigid member 40 is brought into contact with the outer surface of the outer wall 24e of the mold. Next, the support portion 45 is rotated downward (arrow F7) so that the upper end surface 41b of the lower part 41 of the rigid member 40 is below the upper surface of the mounting hole 24g of the outer wall 24e of the mold, and the entire spacer portion 46 is rotated upward (arrow F8) until the support portion 45 is in close proximity to the lower part of the through hole 24f, as shown in Figure 8E. Subsequently, the entire spacer portion 46 is positioned above the connecting wall 39 (shown in Figure 16). After further rotation in the directions of arrows F7 and F8, as shown in Figure 8F, the support portion 45 is rotated towards the vehicle interior (direction of arrow F9) while the entire spacer portion 46 is rotated towards the vehicle interior (arrow F10) so that the upper end surface 41b of the lower portion 41 of the rigid member 40 is directly below the upper surface of the mounting hole 24g of the outer wall 24e of the mold. The support portion 45 is rotated until it is positioned on the vehicle interior side of the through hole 24f, and the chamfered portion 46a, which is the outer portion of the spacer portion 46, is brought close to the vehicle interior side of the vertical wall extension 29b. This allows the rigid member 40 to be attached to the outer wall 24e of the mold.

[0077] When the rigid member 40 is attached to the outer wall 24e of the mold, 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. In addition, the inner surface of the upper part 42 is also positioned to face outwards from the vehicle interior.

[0078] In this mounting state, the rigid member 40 is held by the rear mold molding section 24, so it is possible to prevent 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. More specifically, in addition to the holding of the retaining cylinder section 44 with respect to the through hole 24f, the upper end surface 41b of the lower section 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 section, and the outer surface of the upper section 42 near the upper end surface 41b of the lower section 41 is in contact with the inner surface of the outer wall 24e of the mold section, so it is possible to prevent the rigid member 40 from falling off the rear mold molding section 24.

[0079] (Installation of glass run) As shown in Figure 8F, 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 114c and the upper notch 115c from the outside of the vehicle interior. Also, as shown in Figure 10, when inserting the locking portion 43 into the lower notch 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 114c, so that the locking portion 43 can be easily inserted into the lower notch 114c while absorbing some assembly errors.

[0080] Furthermore, as shown in Figure 8F, by providing the guide portion 47 on the vehicle interior side of the locking portion 43, the gap S5 between the vehicle interior side tip of the spacer portion 46 and the inner wall 24b of the mold portion, and the gap 6 between the upper surface of the spacer portion 46 and the upper wall 24a of the mold portion are both reduced, making it less likely for the spacer portion 46 to be incorrectly assembled to the lower surface of the glass run mounting plate portion 117.

[0081] Subsequently, the guide portion 47 of the rigid member 40 slides against the upper surface of the glass run mounting plate portion 117, guiding the spacer portion 46 to the upper surface of the glass run mounting plate portion 117, and as shown in Figure 9, it is inserted between the upper surface of the glass run mounting plate portion 117 and the lower surface of the upper wall 27 of the upper edge portion 22 of the glass run.

[0082] As shown in Figure 10, 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 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.

[0083] When the glass run 20 is attached to the window frame 110, as shown in Figures 16 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.

[0084] 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 42a 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.

[0085] Furthermore, in all cases, such as when the rear surface 43b of the locking portion 43 of the rigid member 40 contacts the edge 114cb of the lower notch 114c of the glass run mounting plate portion 117 in the vehicle longitudinal direction, or when the contact portion 42a of the rigid member 40 contacts the other edge 28bf of the lower wall notch 28b provided on the upper edge portion 22 of the glass run in the vehicle longitudinal direction, or when the contact portion 42a of the rigid member 40 contacts the rear surface 35b of the protruding wall portion 35 of the rear molded portion 24 (shown in Figure 16), contact is ensured. While this is acceptable, considering variations in the shape and dimensions of the front door 101, the glass run 20, the rigid member 40, and the fit of the front door 101, it is also preferable to set a small gap between the contact portion 42a of the rigid member 40 and 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, or the rear side surface 35b of the protruding wall 35 of the rear molded portion 24, in order to make assembly easier (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.

[0086] (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 hole 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 44 from the outside of the vehicle interior, and the operated parts 44b, 44b are gripped in a direction that brings them closer together. This causes the locking claws 44a, 44a to separate from the edge of the locking hole 124c, releasing the locking state of the locking claws 44a, 44a, and allowing them to be removed from the locking hole 124c.

[0087] (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.

[0088] In addition, because the spacer portion 46 of the rigid member 40 is inserted between the upper surface of the glass run mounting plate portion 117 and the lower surface of the upper wall 27 of the glass run upper edge portion 22, when a downward load is applied to the rear side of the glass run upper edge portion 22, the end portion of the glass run upper edge portion 22 is prevented from deforming downward.

[0089] 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.

[0090] 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]

[0091] As described above, the automotive door sealing structure according to the present invention can be used, for example, in the front doors or rear doors of an automobile. [Explanation of symbols]
