Description

Sealing structure of automobile door

Technical Field

The present disclosure relates to a sealing structure provided in a door for an automobile.

Background

Conventionally, an automobile door is provided with a window glass and a window frame for holding the window glass. A door having such a window frame is provided with a glass run for sealing between the window frame and a peripheral edge portion of a window glass (see, for example, patent documents 1 and 2).

The glass run channels of patent documents 1 and 2 are attached to the window frame from the outside of the vehicle cabin. That is, a glass run attachment plate portion protruding toward the outside of the vehicle cabin and extending in the vehicle longitudinal direction is formed at the upper edge portion of the window frame, and an insertion groove into which the glass run attachment plate portion can be inserted is formed at the upper edge portion of the glass run.

A notch is formed in the vehicle rear portion of the glass run attachment plate portion of patent document 1. In addition, at the vehicle rear portion of the upper side portion of the glass run, an insert member composed of a hard resin material is integrated in a state of being insert-molded to the main body portion of the glass run. The portion of the insert molded with the insert member is a mold molding portion. The insert member has a pin formed on an upper portion thereof so as to protrude upward, and is inserted into a notch portion of the glass run attachment plate portion when the upper edge portion of the glass run is attached to the glass run attachment plate portion.

Further, a hard member is attached to the vehicle rear portion of the upper side portion of the glass run channel of patent document 2. The hard member has a clip-shaped portion fixed to the window frame and a support portion for supporting a vertical edge portion extending downward from an upper edge portion of the glass run.

Problems to be solved by the utility model

However, a general glass run is mainly made of soft rubber (EPDM), soft resin (TPE), and hard resin (PP), and these materials have a larger linear expansion coefficient than a metal material constituting a window frame. Therefore, for example, in a high-temperature atmosphere such as a hot weather, the thermal expansion of the glass run is larger than that of the window frame, and particularly the distal end portion of the upper edge portion of the glass run may protrude more in the front-rear direction than at ordinary temperature. In this way, not only the aesthetic property is deteriorated, but also the opening and closing of the door can be hindered in consideration of the fact that the end portion of the upper edge portion of the glass run comes into contact with a part of the adjacent door.

In contrast, in patent document 1, the protrusion of the distal end portion of the upper edge portion of the glass run is suppressed by inserting the pin of the insert embedded in the upper edge portion of the glass run into the notch portion of the glass run attachment plate portion, but when the insert is provided, the moldability of the molded portion of the glass run deteriorates, a problem arises in that the mold mechanism becomes complicated, and the restriction of the cross-sectional shape of the extruded portion is large in demolding. Further, since welding with the molded portion of the glass run is required, there is also a problem in that the material of the insert is limited.

Therefore, as in patent document 2, a structure is considered in which a hard member is provided that is not insert molded. However, the support portion of the hard member of patent document 2 is a portion for supporting the vertical side portion of the glass run, and is not a portion for directly supporting the upper side portion of the glass run. Therefore, it is considered that the effect of suppressing the protrusion of the distal end portion of the upper edge portion of the glass run under the high temperature atmosphere is insufficient.

Disclosure of Invention

The present disclosure has been made in view of the above-described problems, and an object thereof is to improve the degree of freedom in setting the cross-sectional shape and selecting the material without deteriorating the moldability, and to suppress the protrusion of the distal end portion of the upper edge portion of the glass run under a high-temperature atmosphere.

Means for solving the problems

In order to achieve the above object, a first aspect of the present disclosure is premised on a sealing structure of an automotive door that is attached to a metal sash of an automotive door, and includes a glass run channel that is made of at least one of a resin and a rubber that seals between the sash and a window glass. The upper edge portion of the window frame has a glass run attachment plate portion protruding toward the outside of the vehicle cabin and extending in the vehicle front-rear direction. The glass run attachment plate portion has a notch portion that opens to the outside of the vehicle cabin. The glass run has: a glass run upper edge portion that extends in the vehicle front-rear direction along an upper edge portion of the window frame and is attached to the glass run attachment plate portion from outside the vehicle cabin; a glass run longitudinal edge portion extending in the up-down direction along the longitudinal edge portion of the window frame; and a mold forming portion that connects a portion of the upper edge portion of the glass run that is located at the center in the vehicle longitudinal direction of the end portion in the vehicle longitudinal direction with an upper side of the longitudinal edge portion of the glass run. The glass run upper edge portion includes: an upper wall disposed on an upper surface of the glass run mounting plate portion of the frame upper edge portion and extending in a front-rear direction; a lower wall disposed on a lower surface of the glass run mounting plate portion of the frame upper edge portion and extending in a front-rear direction; and a vertical wall connecting the upper wall and the lower wall outside the vehicle cabin, wherein the glass run upper edge portion is attached to the glass run attachment plate portion by inserting the glass run attachment plate portion into a groove portion between the upper wall and the lower wall, wherein a lower wall notched portion that opens toward the vehicle cabin interior is provided in the lower wall, and wherein a hard member made of a material harder than a material constituting the glass run vertical edge portion is detachably attached to the mold forming portion. The hard member has: an abutting portion that abuts against an edge of the lower wall cutout portion, which is the other of the vehicle front-rear direction edges, from one of the vehicle front-rear directions; and a locking portion inserted into the notch portion, the other side in the vehicle longitudinal direction abutting against and locking one edge portion of the notch portion in the vehicle longitudinal direction.

According to this structure, in a state where the glass run is attached to the window frame, the glass run upper edge portion extends in the vehicle front-rear direction along the upper edge portion of the window frame, and the glass run longitudinal edge portion extends in the up-down direction along the longitudinal edge portion of the window frame. A hard member is attached to a mold forming portion connecting an upper edge portion of the glass run and a longitudinal edge portion of the glass run, an abutting portion of the hard member abuts against the other edge of the lower wall notched portion provided in the upper edge portion of the glass run in the vehicle longitudinal direction, and an engaging portion of the hard member abuts against and engages with one edge portion of the notched portion of the glass run attachment plate portion in the vehicle longitudinal direction. At this time, the direction in which the abutment portion abuts against the other edge in the vehicle longitudinal direction of the lower wall cutout portion provided in the glass run channel upper edge portion and the direction in which the engagement portion abuts against one edge in the vehicle longitudinal direction of the cutout portion of the glass run channel mounting plate portion are opposite to each other, and therefore when the glass run channel upper edge portion extends in a high-temperature atmosphere, the extension thereof is restrained by the glass run channel mounting plate portion and the hard member, and as a result, the protrusion of the distal end portion of the glass run channel upper edge portion is suppressed. At this time, since the abutting portion of the hard member is in direct abutment with the other edge in the vehicle longitudinal direction of the lower wall cutout portion provided in the upper edge portion of the glass run, the protrusion suppressing effect of the distal end portion of the upper edge portion of the glass run is sufficiently improved.

Further, since the hard member is detachably attached to the mold molding portion, deterioration of moldability and complication of the mold mechanism, such as in insert molding, are not caused, and the degree of freedom in setting the sectional shape and selecting the material of the hard member is improved.

In a second aspect of the present disclosure, a protruding wall portion of the mold portion is integrally molded with respect to the other edge of the lower wall cutout portion in the vehicle longitudinal direction, and the abutment portion abuts against the other edge of the lower wall cutout portion in the vehicle longitudinal direction from one edge of the lower wall cutout portion in the vehicle longitudinal direction via the protruding wall portion.

According to this structure, the glass run attachment plate portion (metal), the hard member (hard resin: POM), and the lower wall (hard resin: talc-added PP) can be each composed of a hard member, and therefore are hardly deformed by flexing in the front-rear direction, but since the protruding wall portion of the rear side mold forming portion is formed of a material slightly softer than the lower wall, they can be slightly deformed by flexing in the front-rear direction. Therefore, even when a deviation in the shape and size of the door, a deviation in the shape and size of the glass run, a deviation in the shape and size of the hard member, a deviation in the fitting of the door, or the like occurs, the assembly becomes easy.

A protruding wall portion of a third aspect of the present disclosure extends in the up-down direction, and an abutting portion extends along the protruding wall portion in the up-down direction.

According to this structure, the contact area between the protruding wall portion of the mold forming portion and the contact portion of the hard member can be ensured to be large, and therefore the hard member can be stabilized when the upper edge portion of the glass run is extended in a high-temperature atmosphere.

A fourth aspect of the present disclosure provides that the abutment portion is provided at an upper portion of the hard member, and the locking portion protrudes upward from the upper portion of the hard member.

According to this configuration, the interval between the contact portion that contacts the protruding wall portion of the mold forming portion and the engagement portion that contacts the edge portion of the notch portion of the glass run attachment plate portion in the vertical direction can be reduced, and therefore, the effect of suppressing the extension of the upper edge portion of the glass run can be further improved.

In a fifth aspect of the present disclosure, the mold forming portion is provided with a hole portion penetrating in the vehicle interior-exterior direction, and the hard member is provided with a holding cylinder portion inserted from the vehicle exterior side toward the inside and held in the hole portion.

According to this configuration, the hard member can be held by the mold forming portion by inserting the holding cylinder portion of the hard member into the hole portion of the mold forming portion, so that the hard member can be prevented from coming off the mold forming portion during transportation or the like before mounting to the window frame, and workability in mounting can be improved.

In a sixth aspect of the present disclosure, the window frame is provided with a locking hole, and the holding tube is provided with a locking claw portion that is locked with an edge portion of the locking hole.

According to this configuration, the locking claw portion is locked to the locking hole, whereby the hard member can be fixed to the window frame, and the hard member can be stabilized.

In a seventh aspect of the present disclosure, the hard member is provided with an operated portion for operating the locking claw portion in a direction away from an edge portion of the locking hole.

According to this configuration, after the locking claw portion is locked to the locking hole, for example, when the hard member is removed from the window frame during repair, the operator can easily release the locking claw portion from the edge portion of the locking hole by operating the operated portion.

In an eighth aspect of the present disclosure, the dimension of the locking portion in the vehicle longitudinal direction is set to be shorter than the dimension of the notch portion in the vehicle longitudinal direction.

According to this structure, when the locking portion of the hard member is inserted into the notch portion of the glass run attachment plate portion, the locking portion is less likely to interfere with the edge portion of the notch portion, and workability is improved.

Effects of the utility model

As described above, the hard member is detachably attached to the mold forming section, and the hard member includes: an abutting portion that abuts against an edge of the other vehicle front-rear direction side portion of a lower wall cutout portion provided at an upper edge portion of the glass run channel from one vehicle front-rear direction side portion; and a locking portion that is brought into contact with and locked to one edge portion of a notch portion formed in the glass run attachment plate portion in the vehicle front-rear direction from the other side in the vehicle front-rear direction, whereby the moldability of the mold molding portion is not deteriorated, the degree of freedom in setting the cross-sectional shape and selecting the material can be improved, and the protrusion of the distal end portion of the upper edge portion of the glass run can be suppressed.

Detailed Description

Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the utility model, its application, or its uses.

Fig. 1 is a right side view of an automobile 100 to which a sealing structure of an automobile door according to an embodiment of the present utility model is applied. A front door 101 and a rear door 102 are provided at the side of the automobile 100. The front door 101 and the rear door 102 are attached to the body of the automobile 100 via hinges not shown. In the description of this embodiment, the vehicle front side is simply referred to as "front", and the vehicle rear side is simply referred to as "rear".

(Structure of front door)

As shown in fig. 2, the front door 101 includes: a door main body 103 constituting a lower half of the front door 101; a window frame 110 constituting an upper half of the front door 101; a window glass G; and a glass run 20. The door body 103 includes a metal body outer panel 103a disposed outside the vehicle cabin and a metal body inner panel disposed inside the vehicle cabin, not shown, and a space is formed between the body outer panel 103a and the body inner panel.

The window frame 110 is a member for holding a peripheral edge portion of the window glass G and guiding the window glass G in the up-down direction. The window glass G is provided to be movable up and down with respect to the door main body 103. A lifting device (not shown) for lifting and lowering the window glass G is provided in the door body 103, and the window glass G is switched between a closed state in which it is lifted and an open state in which it is lowered by the lifting device.

The window frame 110 includes a frame front edge 111, a frame upper edge 112, and a frame rear edge 113, and the frame front edge 111, the frame upper edge 112, and the frame rear edge 113 hold the peripheral edge of the window glass G in a closed state. That is, the frame front edge 111 protrudes upward from the front side of the belt line BL of the door body 103, and the frame rear edge 113 protrudes upward from the rear side of the belt line BL of the door body 103. The upper end of the frame front side 111 is located lower than the upper end of the frame rear side 113. The frame upper side 112 extends in the front-rear direction, and the front end of the frame upper side 112 is connected to the upper end of the frame front side 111, and the rear end of the frame upper side 112 is connected to the upper end of the frame rear side 113. Since the upper end portion of the frame front side portion 111 is located lower than the upper end portion of the frame rear side portion 113, the frame upper side portion 112 is gently curved so as to descend toward the front side. The curved shape of the frame upper edge portion 112 corresponds to the shape of the top of the automobile 100.

Fig. 3 shows a line III-III section of the upper frame edge 112 of the window frame 110. As shown in fig. 3, the frame upper portion 112 is constituted by an upper outer panel 114 outside the vehicle cabin and an upper inner panel 115 inside the vehicle cabin. The upper outer panel 114 and the upper inner panel 115 are made of metal such as steel plate. An upper outer engagement plate portion 114a protruding downward is formed at a lower portion of the upper outer plate 114. Further, an upper inner joint plate portion 115a that overlaps with the vehicle interior side of the upper outer joint plate portion 114a is formed so as to protrude downward in a lower portion of the upper inner panel 115. The upper outer engagement plate portion 114a and the upper inner engagement plate portion 115a are engaged.

An upper outer lower plate portion 114b protruding toward the outside of the vehicle cabin is formed at an upper portion of the upper outer plate 114. Further, an upper inner upper plate portion 115b is formed on the upper inner plate 115 so as to protrude outward of the vehicle cabin and overlap with the upper side of the upper outer plate portion 114b. The upper outer lower plate portion 114b is joined to the upper inner upper plate portion 115b, thereby constituting a glass run channel attaching plate portion 117 for attaching the glass run channel 20 from the outside of the vehicle cabin. The glass run mounting plate portion 117 extends in the front-rear direction. A cut-and-raised portion 115d is formed in the upper inner upper plate portion 115b constituting the glass run attachment plate portion 117.

Fig. 5 shows a V-V line cross section of the frame rear edge 113 of the window frame 110 shown in fig. 2. As shown in fig. 5, the frame rear portion 113 is also composed of a vertical side outer panel 124 and a vertical side inner panel 125, similar to the frame upper portion 112. The vertical side outer panel 124 and the vertical side inner panel 125 are made of metal such as steel plate.

As shown in fig. 11, which is a section taken along line XI-XI of fig. 6, a longitudinal outer joint plate portion 124a protruding rearward is formed at the rear portion of the longitudinal outer panel 124. Further, a vertical side inner joint plate portion 125a that overlaps with the vehicle interior side of the vertical side outer joint plate portion 124a is formed at the rear portion of the vertical side inner panel 125 so as to protrude rearward. The longitudinal side outer engagement plate portion 124a is engaged with the longitudinal inner engagement plate portion 125a.

As shown in fig. 5, a vertical side outer front plate portion 124b protruding toward the front side is formed at the front portion of the vertical side outer panel 124. Further, a vertical side inner front plate portion 125b that overlaps the vehicle interior side of the vertical side outer front plate portion 124b is formed at the front portion of the vertical side inner panel 125 so as to protrude toward the front side. The longitudinal side outer front plate portion 124b is joined to the longitudinal side inner front plate portion 125b.

A sash member 126 is attached to the vehicle cabin outer side of the longitudinal side outer panel 124. The window frame member 126 is made of, for example, a metal made of a steel plate or the like, and extends in the vertical direction as shown in fig. 2. The lower end portion of the window frame member 126 reaches the inside of the door main body 103. As shown in fig. 5, the window frame member 126 has: a fixing plate portion 126a that extends along the vehicle-cabin-outside surface of the longitudinal side outer panel 124 and is fixed to the longitudinal side outer front panel portion 124b of the longitudinal side outer panel 124; a rear plate portion 126b extending from the fixed plate portion 126a toward the outside of the vehicle cabin; and a side plate portion 126c extending from an end portion of the rear plate portion 126b on the vehicle outside toward the front side. The fixing plate portion 126a, the rear plate portion 126b, and the side plate portion 126c of the window frame member 126 form a glass run attachment groove portion 127 that is open toward the front.

As shown in fig. 11, which is a sectional view taken along line XI-XI of the glass run channel 20 of fig. 6, which will be described later, and which shows a sectional view of the glass run channel 20 mounted to the window frame 110, a locking hole 124c into which the locking claw portion 44a of the hard member 40, which will be described later, is inserted is formed in the upper side of the vertical side outer panel 124. The locking hole 124c is formed to penetrate the vertical side outer panel 124, and is formed, for example, by a circular hole. Reference numeral 130 shown in fig. 5, 11 and fig. 9 (a cross-sectional view taken along line VIII-VIII of the glass run channel 20 of fig. 6, which will be described later, that is, a cross-sectional view of the state in which the glass run channel 20 of fig. 8B is attached to the window frame 110, that is, fig. 9) described later is a decorative piece. The garnish 130 is a resin member extending in the vertical direction along the vehicle interior outer side of the frame rear portion 113, and is provided for decoration. The garnish 130 is fixed to the outer panel 124 on the longitudinal side by fixing members such as clips, screws, and double-sided tape (not shown).

(Structure of glass run)

The glass run channel 20 shown in fig. 4 is attached to the window frame 110, and is a sealing member for sealing between the window frame 110 and the window glass G. The glass run 20 is made of at least one of a resin and a rubber, and is made of a hard resin (for example, PP), a thermoplastic elastomer (TPE), a solid (non-foamed) rubber (for example, EPDM), a foamed rubber (for example, EPDM), or the like. The coefficient of linear expansion of these materials is greater than the coefficient of linear expansion of the metallic pieces that make up the window frame 110. The material of the glass run 20 may be changed depending on the location, but in this embodiment, a metal-free structure is formed without a metal core material.

As shown in fig. 2 and 4, the glass run 20 has: a glass run front edge portion (glass run longitudinal edge portion) 21 extending in the up-down direction along the frame front edge portion 111; a glass run upper edge portion 22 extending in the front-rear direction along the frame upper edge portion 112; and a glass run rear edge portion (glass run longitudinal edge portion) 23 that extends in the up-down direction along the frame rear edge portion 113. The glass run front side portion 21 is a portion attached to the frame front side portion 111, the glass run upper side portion 22 is a portion attached to the frame upper side portion 112 from the outside of the vehicle cabin, and the glass run rear side portion 23 is a portion attached to the frame rear side portion 113.

The glass run 20 further includes a rear mold forming portion 24 that connects a portion of the glass run upper edge portion 22 that is located at the center in the front-rear direction of the rear end portion 22a with the upper side of the glass run rear edge portion 23. The glass run 20 further includes a front side mold forming portion 25 that connects a portion of the glass run upper side portion 22 that is located at the center in the front-rear direction of the front side end portion 22b to the upper side of the glass run front side portion 21. In fig. 4, the boundary between the rear side mold forming part 24 and the glass run upper side 22 and the glass run rear side 23 is shown by a broken line, and the boundary between the front side mold forming part 25 and the glass run upper side 22 and the glass run front side 21 is also shown by a broken line.

The glass run front portion 21, the glass run upper portion 22, and the glass run rear portion 23 are extrusion-molded portions (also referred to as extrusion portions) formed by extruding a material from a die. On the other hand, the rear side mold forming portion 24 and the front side mold forming portion 25 are portions formed by injecting a material into the opened and closed mold, and can integrate the glass run upper side portion 22 and the glass run rear side portion 23 via the rear side mold forming portion 24 when the rear side mold forming portion 24 is formed, and can integrate the glass run upper side portion 22 and the glass run front side portion 21 via the front side mold forming portion 25 when the front side mold forming portion 25 is formed. Here, as a material that can be used for the rear side mold forming portion 24 and the front side mold forming portion 25, a thermoplastic elastomer (TPE) that is one type of soft resin can be exemplified.

The cross-sectional shape of the glass run upper edge 22 is shown in fig. 3. The glass run upper edge 22 includes: an upper wall 27 disposed on an upper surface of the glass run mounting plate portion 117 of the frame upper edge portion 112 and extending in the front-rear direction; a lower wall 28 disposed on a lower surface of the glass run mounting plate 117 of the frame upper edge 112 and extending in the front-rear direction; and a vertical wall 29 that connects the vehicle outside of the upper wall 27 and the lower wall 28. The glass run upper edge portion 22 is attached to the glass run attachment plate portion 117 by inserting the glass run attachment plate portion 117 into the groove portion M between the upper wall 27 and the lower wall 28. An upper protrusion 27a is formed on the lower surface of the upper wall 27, which engages with a cut-up portion 115d formed in the glass run attachment plate portion 117. Further, an upper protrusion 27c that elastically contacts the upper surface of the glass run attachment plate 117 is formed on the lower surface of the upper wall 27 on the vehicle interior side of the upper protrusion 27a. Further, a lower protrusion 28a that elastically contacts the lower surface of the glass run attachment plate 117 is formed on the upper surface of the lower wall 28.

On the upper surface of the upper wall 27, 2 upper lips 27b are formed so as to protrude upward and elastically contact a vehicle body opening (not shown). The vertical wall 29 extends below the lower wall 28, and an outer lip 29a that elastically contacts the outer surface of the vehicle cabin of the window glass G is formed at the lower end portion of the vertical wall 29. An extension wall 30 extending downward is formed on the vehicle interior side of the lower wall 28. The extension wall 30 is formed to cover the vehicle interior outer surface of the upper outer joint plate portion 114 a. Further, a decorative lip portion 30b extending upward from the lower end portion of the extension wall 30 is formed on the vehicle interior surface of the extension wall 30 so as to cover the vehicle interior surface of the upper inner joint plate portion 115 a. An inner lip 30a that contacts the inner surface of the window glass G is formed on the outer surface of the vehicle cabin of the extension wall 30. As shown in fig. 8A, 8B, 8C, and 9, the lower wall 28 is formed such that the lower wall cutout 28B opens toward the vehicle interior surface.

Here, as a material that can be used for the glass run upper edge 22 shown in fig. 3, for example, polypropylene (PP) in which the upper wall 27, the lower wall 28, and the vertical wall 29 are one of hard resins, and thermoplastic elastomer (TPE) in which the outer lip 29a, the extension wall 30, the inner lip 30a, the decorative lip 30b, and the upper lip 27b are one of soft resins can be exemplified. The linear expansion coefficient of polypropylene (PP) is larger than that of a metal material which is hard to be thermoplastic elastomer (TPE).

As shown in fig. 5, the glass run rear edge portion 23 is inserted from the front side and attached to the glass run attachment groove portion 127, and in this state, the glass run rear edge portion 23 is fitted into the window frame member 126 without being detached. The glass run rear edge portion 23 has: a longitudinal side outer wall 31 located outside the vehicle cabin and extending in the up-down direction; a longitudinal side inner wall 32 located inside the vehicle cabin and extending in the up-down direction; and a rear wall 33 connecting the rear end of the vertical side outer wall 31 and the rear end of the vertical side inner wall 32. The longitudinal side outer side wall 31 and the longitudinal side inner side wall 32 are held by the window frame member 126. A rear edge portion of the window glass G is disposed between the vertical side outer wall 31 and the vertical side inner wall 32. The 2 longitudinal side outer lips 31a formed on the longitudinal side outer side wall 31 elastically contact the inner and outer surfaces of the window glass G, and the longitudinal side inner lip 32a formed on the longitudinal side inner side wall 32 elastically contacts the inner surface of the window glass G, thereby securing sealing properties.

Here, as a material that can be used as the glass run rear edge portion 23 and the glass run front edge portion 21 (both referred to as a glass run longitudinal edge portion), a thermoplastic elastomer (TPE) that is one type of soft resin can be exemplified. The material may be a non-foaming material or a foaming material at the section. Thermoplastic elastomers (TPE) have a greater linear expansion coefficient than metal parts, regardless of non-foamed and foamed materials.

As shown in fig. 6, the glass run upper edge 22 has a vertical wall extension 29b extending to the distal end 22a side than the connecting portions L1 and L2 between the glass run rear edge 23 and the rear side mold forming portion 24. The vertical wall extension 29b extends along the glass run upper edge 22 to the tip end 22a. The portion of the vertical wall extension 29b outside the cabin is formed by molding to integrate a mold portion outer side wall 24e extending downward as a part of the rear mold portion 24.

The connection portion between the vertical wall extension 29b and the mold portion outer side wall 24e is denoted by L4. In addition, the connection portion between the rear side molded portion 24 and the extension wall 30 and the inner lip 30a in the glass run upper edge portion 22 is denoted by L3. The connection portion between the rear end 22a, which is the rear end of the vertical wall extension 29b in the glass run upper edge 22, and the rear mold forming portion 24 is denoted by L5. As shown in fig. 7, L6 represents a connecting portion between the upper protrusion 27c and the rear mold forming portion 24. A mold inner wall 24b extending downward to substantially the same position as the lower end of the mold outer wall 24e is provided near the rear end of the rear mold portion 24, while maintaining a shape similar to the upper protrusion 27c for a while beyond the rear side of the connecting portion L6.

As shown in fig. 8A, 8B, and 9, a through hole (hole portion) 24f penetrating in the vehicle interior-exterior direction is formed in the mold portion outer wall 24 e. The through hole 24f is not circular but has a nearly rectangular shape. A holding cylinder 44 of the hard member 40, which will be described later, is inserted into the through hole 24f. Further, an upper portion 42 described later is inserted into the mold portion outer side wall 24e at a position above the through hole 24f, and an attachment hole 24g for attaching a hard member 40 described later is formed to penetrate in the vehicle interior-exterior direction.

As shown in fig. 16A and 16B, which will be described later, a protruding wall portion 35 protruding toward the vehicle interior side is provided in front of the mounting hole 24g of the mold portion outer wall 24 e. The protruding wall portion 35 extends in the up-down direction, and an upper end portion of the protruding wall portion 35 is located at an upper end portion of the mold portion outer side wall 24 e. The lower end portion of the protruding wall portion 35 is continuous with the upper end portion of the rear wall 33 of the glass run rear edge portion 23.

A rear protruding wall portion 36 protruding toward the vehicle interior side is provided behind the mounting hole 24g of the mold portion outer wall 24 e. The rear protruding wall 36 also extends in the vertical direction as in the protruding wall 35, and the upper end of the rear protruding wall 36 is located at the upper end of the mold section outer side wall 24 e. A first wall portion 37 and a second wall portion 38 are provided behind the rear protruding wall portion 36 of the mold portion outer side wall 24e, similarly to the rear protruding wall portion 36. A connecting wall 39 protruding toward the vehicle interior side is provided at the upper end portion of the mold portion outer wall 24 e. The connecting wall 39 extends in the front-rear direction and connects the upper end of the rear protruding wall 36, the upper end of the first wall 37, and the upper end of the second wall 38.

(Structure of glass run mounting plate portion)

Fig. 10 is a plan view of the glass run mounting plate 117 shown in fig. 9, including a rear vicinity thereof, in an X-X section. As shown in fig. 10, a lower notch 114c is formed in an upper outer plate 114b constituting the glass run attachment plate 117 so as to open toward the outside of the vehicle cabin. Further, in the upper inner upper plate portion 115b constituting the glass run attachment plate portion 117, the upper notch portion 115c is formed so as to open toward the outside of the vehicle cabin.

The lower notch 114c is disposed inside the upper notch 115c when the glass run attachment plate 117 is viewed from above. Specifically, the width (the dimension in the front-rear direction) of the upper notch 115c is set to be wider than the width (the dimension in the front-rear direction) of the lower notch 114c, the front edge of the upper notch 115c is located forward of the front edge of the lower notch 114c, and the rear edge of the upper notch 115c is located rearward of the rear edge of the lower notch 114c. The depth (dimension in the vehicle interior-exterior direction) of the upper cutout portion 115c is set to be deeper than the depth (dimension in the vehicle interior-exterior direction) of the lower cutout portion 114c, and the edge portion of the upper cutout portion 115c on the vehicle interior side is located on the vehicle interior side than the edge portion of the lower cutout portion 114c on the vehicle interior side.

(Structure of hard Member)

As shown in fig. 6 to 11, etc., a hard member 40 made of a material constituting the glass run upper edge 22, that is, a material hard to thermoplastic elastomer (TPE), is provided on the die section outer side wall 24e of the rear side die forming section 24. As shown in fig. 11, the hard member 40 is covered with the garnish 130. The hard member 40 is, for example, a member obtained by injection molding a hard resin such as Polyacetal (POM).

The material constituting the hard member 40 may be other than POM, and examples thereof include a hard resin material and a metal material. As shown in fig. 8A and 8B, the hard member 40 is detachably attached to the mold section outer side wall 24e of the rear side mold section 24. The removable state refers to a state in which the hard member 40 is not insert molded (embedded) in the rear side mold molding portion 24 and is not welded to the mold molding material of the rear side mold molding portion 24 constituting the glass run upper edge portion 22, and is, for example, a state in which the hard member 40 can be easily removed or attached by hand.

Since the hard member 40 is not insert molded (embedded) in the rear side mold molding portion 24, the moldability of the rear side mold molding portion 24 becomes good, and the mold mechanism is not complicated, which is convenient in terms of moldability and equipment. In addition, in demolding, the restriction of the extruded sectional shape of the glass run upper edge 22 is also reduced. Further, since the hard member 40 is not insert molded (embedded), the degree of freedom in setting the shape of the hard member 40 and selecting the material is improved. By increasing the degree of freedom in selecting the material of the hard member 40, for example, a material that is hard and strong, a material that is not heat resistant, or the like can be selected. Further, since the hard member 40 can be attached and detached, when the hard member 40 is broken, the broken hard member 40 is detached from the glass run channel 20, and a new hard member 40 is attached to the glass run channel 20, so that the glass run channel 20 can be reused.

Fig. 12 to 14 show a single body of the hard member 40. The hard member 40 has a plate shape long in the up-down direction as a whole. The hard member 40 includes a lower side 41 that is long in the front-rear direction and an upper side 42 that is long in the up-down direction, and these are integrally molded. The length of the upper side portion 42 in the vehicle longitudinal direction is shorter than the length of the lower side portion 41 in the vehicle longitudinal direction. As shown in fig. 8B, the upper portion 42 is continuous with the upper edge portion of the lower portion 41, and is located on the vehicle interior side than the upper edge portion of the lower portion 41. When the upper side portion 42 is viewed in the front-rear direction, the upper end of the upper side portion 42 is inclined so as to be positioned further toward the vehicle interior side.

As shown in fig. 13 and 14, a front-side projecting portion 42b projecting toward the vehicle interior side and extending in the up-down direction is formed at the front end portion of the upper side portion 42. The front surface of the front projecting portion 42b is also a part of the front surface of the upper portion 42, and as shown in fig. 16, the upper portion of the front surface of the front projecting portion 42b is an abutment portion 42a that abuts against the projecting wall portion 35 from the rear. As shown in fig. 16A and 16B, in a state where the hard member 40 is attached to the mold portion outer side wall 24e, the abutment portion 42a extends in the up-down direction along the protruding wall portion 35. This ensures a large contact area between the contact portion 42a and the protruding wall portion 35. As shown in fig. 13 and 14, a rear-side projection 42c is formed at the rear end of the upper portion 42, projecting toward the vehicle interior side and extending in the up-down direction. The rear end portion of the upper side portion 42 is sized so as to be disposed forwardly apart from the rear protruding wall portion 36 of the mold portion outer side wall 24 e.

Further, an engagement portion 43 is provided on the upper side portion 42. The locking portion 43 has a columnar shape or a pin shape protruding upward from the upper portion of the upper portion 42. As shown in fig. 10, the locking portion 43 is inserted into the lower notch 114c and the upper notch 115c from the outside of the vehicle cabin. When the locking portion 43 is inserted into the lower notch portion 114c, it abuts against and is locked with the rear edge portion 114cb of the lower notch portion 114c from the front (the other side in the vehicle front-rear direction).

Here, the dimension of the locking portion 43 in the front-rear direction is set to be shorter than the dimension of the lower notch portion 114c in the front-rear direction, and in a state of being 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 separated rearward from the front edge portion 114cf of the lower notch portion 114 c. Further, the upper notch 115c is wider than the lower notch 114c, and therefore does not interfere with the locking portion 43.

As shown in fig. 13 and 14, a rib 42d is formed on the vehicle interior side surface of the upper portion 42. The upper portion of the rib 42d is connected to the lower portion of the locking portion 43. The rib 42d extends in the up-down direction, and the lower the protruding height is. By setting the rib 42d, the engagement strength of the locking portion 43 as the main body portion with respect to the upper side portion 42 can be improved, and even if the locking portion 43 receives a large force, the locking portion 43 can be prevented from being broken or damaged with respect to the upper side portion 42.

Further, a lower protruding portion 41a protruding toward the vehicle interior side and extending in the up-down direction is formed at the front end portion of the lower portion 41. Further, a holding tube 44 is provided in the middle of the lower portion 41 in the front-rear direction. The holding tube portion 44 protrudes from the lower side portion 41 toward the vehicle interior side, and as shown in fig. 8A and 8B, is inserted into the through hole 24f of the mold portion outer side wall 24e from the vehicle exterior side toward the inner side, thereby holding the hard member 40 with respect to the glass run rear side mold portion 24. The cross-sectional shape of the holding cylinder 44 corresponds to the shape of the through hole 24f, and the outer peripheral surface of the holding cylinder 44 contacts the inner peripheral surface of the through hole 24f, so that the holding cylinder 44 is less likely to come off from the through hole 24f due to friction between the two. Further, the holding tube portion 44 may be pressed into the through hole 24f.

As shown in fig. 9 and 11, the position of the holding tube 44 substantially corresponds to the position of the locking hole 124c of the vertical side outer panel 124. As shown in fig. 11, the holding tube 44 is provided with locking claws 44a, 44a that are locked with the edges of the locking hole 124 c. That is, as shown in fig. 13 and 14, the support portions 45 that support the locking claw portions 44a, 44a are formed to protrude toward the vehicle interior side at the vehicle interior side end portion of the holding cylinder portion 44. The support portion 45 has an upper protruding wall 45a protruding from the upper portion of the holding tube portion 44 toward the vehicle interior side and a lower protruding wall 45b protruding from the lower portion of the holding tube portion 44 toward the vehicle interior side, and has a pair of coupling portions 45c, which are one coupling portion 45c in the front-rear direction that couples the front end portion of the upper protruding wall 45a and the front end portion of the lower protruding wall 45b, and the other coupling portion 45c in the front-rear direction that couples the rear end portion of the upper protruding wall 45a and the rear end portion of the lower protruding wall 45b, and is cylindrical as a whole. As shown in fig. 13, 14, and fig. 15A, which is a section taken along line A-A of fig. 14, the pair of connecting portions 45c, 45c are disposed with a gap S1 therebetween in the front-rear direction, and one connecting portion 45c is capable of being deformed by bending in a direction approaching the other connecting portion 45c due to elasticity of the resin.

The base end of the one locking claw 44a is connected to the one connecting portion 45c, and the one locking claw 44a is in a position protruding from the one connecting portion 45c in the front-rear direction. Similarly, the base end portion of the other locking claw portion 44a is connected to the other connecting portion 45c, and the other locking claw portion 44a is in a posture protruding from the other connecting portion 45c toward the other side in the front-rear direction. As shown in fig. 14 and 15A, a gap S2 of the same extent as the gap S1 of the coupling portions 45c, 45c is formed between the two locking claw portions 44a, 44 a.

As shown in fig. 13 and 15A, both the locking claw portions 44a and 44a are connected to the pair of connecting portions 45c and 45c of the holding tube portion 44 on the base end side, but the two locking claw portions 44a and 44a are more likely to be deformed by bending because the side opposite to the base end side is not connected to the holding tube portion 44 with the gap S3 provided therebetween.

As shown in fig. 15A, operated portions 44b, 44b for operating the locking claw portions 44a, 44a in a direction away from the edge portion of the locking hole 124c are provided at the vehicle-cabin-outside end portions of the locking claw portions 44a, 44 a. The operated portions 44b and 44b are disposed in the holding cylinder portion 44 with a gap S4 therebetween in the front-rear direction. The operated portions 44b and 44b are not connected to the holding tube portion 44, as are the two locking claw portions 44a and 44 a. By moving the operated portions 44b, 44b in the directions approaching each other, the interval between the locking claw portions 44a, 44a becomes narrower, and the operated portions can be separated from the edge portion of the locking hole 124 c.

(installation of hard Member)

When the hard member 40 is attached to the mold portion outer wall 24e, the upper portion 42 is attached first because the upper portion 42 cannot be attached when the holding tube portion 44 is attached first. First, as shown in fig. 8A, in a state in which the hard member 40 is oriented in the lateral direction so that the support portion 45 is oriented downward and the locking portion 43 is oriented toward the vehicle interior side, the locking portion 43 is inserted into the mounting hole 24g, and the lower side upper end 41b is inserted into contact with the vehicle exterior side surface of the mold portion exterior side wall 24 e. At this time, since the width of the mounting hole 24g in the vehicle front-rear direction is set to be substantially equal to the width of the upper side portion 42 in the vehicle front-rear direction, the lower side portion 41, which is set to be larger than the upper side portion 42 in the vehicle front-rear direction, cannot be inserted into the mounting hole 24g.

Next, from the state shown in fig. 8A in which the hard member 40 is set in the lateral direction, the state shown in fig. 8B in which the hard member 40 is set in the inclined state is performed while the hard member 40 is rotated. More specifically, as shown in fig. 8A, the upper protruding wall 45a of the holding tube portion 44 of the lower portion 41 is rotated in the F1 direction (outside of the vehicle cabin) so that the vicinity of the connecting portion between the upper portion 42 and the lower portion 41 is the rotation center and the upper end surface 41B of the lower portion 41 reaches the lower side of the upper side surface of the mounting hole 24g of the mold portion outer side wall 24e, and the locking portion 43 of the upper portion 42 is rotated in the F3 direction (outside of the vehicle cabin) to be in the state shown in fig. 8B.

Further, from the state shown in fig. 8B in which the hard member 40 is tilted, the hard member 40 is rotated while the hard member 40 is turned to the state shown in fig. 8C in which the hard member 40 is erected. More specifically, as shown in fig. 8B, the upper protruding wall 45a of the holding tube portion 44 of the lower portion 41 is rotated in the F5 direction (vehicle interior side) so that the vicinity of the connecting portion between the upper portion 42 and the lower portion 41 is the rotation center and the upper end surface 41B of the lower portion 41 is rotated in the F4 direction (vehicle exterior side) so as to come directly below the upper side surface of the mounting hole 24g of the mold portion outer side wall 24e, and the locking portion 43 of the upper portion 42 is inserted into the through hole 24F so as to be rotated in the F6 direction (vehicle exterior side), thereby completing the mounting as shown in fig. 8C.

In this state, since the hard member 40 is held by the rear side mold forming portion 24, the hard member 40 can be restrained from coming off the rear side mold forming portion 24 before the glass run channel 20 is attached to the window frame 110.

More specifically, in addition to the holding of the holding cylinder portion 44 with respect to the through hole 24f, the upper end surface 41b of the lower portion 41 is disposed immediately below the upper side surface of the mounting hole 24g of the mold portion outer side wall 24e and is in contact with the vehicle interior side surface of the mold portion outer side wall 24e, and the vehicle exterior side surface of the upper portion 42 in the vicinity of the upper end surface 41b of the lower portion 41 is in contact with the vehicle interior side surface of the mold portion outer side wall 24e, so that the hard member 40 can be prevented from falling off from the rear side mold forming portion 24.

When the hard member 40 is attached to the mold outer side wall 24e, the vehicle exterior side surface of the lower portion 41 faces the vehicle exterior side as shown in fig. 6, while the front end portion of the holding cylinder portion 44, the locking claw portion 44a, and the support portion 45 are disposed further toward the vehicle interior side than the mold outer side wall 24e as shown in fig. 7. The vehicle exterior side surface of the upper side portion 42 is also disposed so as to face the vehicle interior side.

Further, as shown in fig. 8C and 9, a lower wall cutout 28b is formed in the lower wall 28 of the glass run upper edge 22, the lower wall cutout 28b being cut out at the vehicle interior side portion and opened to the interior side, but the dimension in the vehicle longitudinal direction of the locking portion 43 shown in fig. 10 is set to be shorter than the cut-out dimension in the vehicle longitudinal direction of the lower wall cutout 28 b.

As shown in fig. 8C and 9, the locking portion 43 is disposed so as to protrude upward from the upper surface of the lower wall extension portion 28C that remains without being cut.

(installation of glass run)

After the hard member 40 is attached to the glass run channel 20, the glass run channel 20 is attached to the window frame 110. As shown in fig. 9, when the glass run upper edge portion 22 is attached to the glass run attachment plate portion 117, the locking portion 43 of the hard member 40 is inserted into the lower notch portion 114c and the upper notch portion 115c from outside the vehicle cabin. Further, as shown in fig. 10, when the locking portion 43 is inserted into the lower notch portion 114c, the dimension of the locking portion 43 in the front-rear direction is set to be shorter than the dimension of the lower notch portion 114c in the front-rear direction, so that the locking portion 43 can be easily inserted into the lower notch portion 114c while absorbing a small assembly error.

In a state where the locking portion 43 is 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 114 c. As shown in fig. 11, the locking claw portions 44a, 44a are inserted into the locking holes 124c of the vertical side outer panel 124. When the locking claw portions 44a, 44a are inserted into the locking hole 124c, as shown in fig. 13, 14 and 15A, the locking claw portions 44a, 44a and the coupling portions 45c, 45c are easily elastically deformed by the elasticity of the resin and the gaps S1 to S4. By the shape recovery after the insertion, as shown in fig. 11, the locking claw portions 44a, 44a are locked from the vehicle interior side with the peripheral edge portion of the locking hole 124 c.

When the glass run channel 20 is attached to the window frame 110, as shown in fig. 16A and 10, the abutting portion 42a of the hard member 40 abuts against the other edge 28bf of the lower wall cutout portion 28b provided in the glass run channel upper edge portion 22 in the vehicle longitudinal direction, and the rear surface 43b of the locking portion 43 of the hard member 40 abuts against and is locked to the one edge 114cb of the lower side cutout portion 114c of the glass run channel attachment plate portion 117 in the vehicle longitudinal direction. Here, fig. 10 shows, in broken lines, the positional relationship between the lower wall cutout 28b and the other edge (lower wall cutout front edge) 28bf in the vehicle longitudinal direction of the lower wall cutout.

At this time, the direction in which the abutment portion 42a abuts against the other edge 28bf of the lower wall cutout portion 28b provided in the glass run channel upper edge portion 22 in the vehicle longitudinal direction and the direction in which the rear surface 43b of the locking portion 43 abuts against one edge 114cb of the lower side cutout portion 114c in the vehicle longitudinal direction are opposite to each other, and therefore, when the glass run channel upper edge portion 22 is to be stretched in a high-temperature atmosphere, the stretching thereof is restricted by the glass run channel mounting plate portion 117 and the hard member 40, and as a result, the protrusion of the distal end portion 22a of the glass run channel upper edge portion 22 rearward is suppressed. At this time, the abutting portion 42b of the hard member 40 is in direct abutment with the other edge 28bf of the lower wall cutout portion 28b provided in the glass run channel upper edge portion 22 in the vehicle front-rear direction, so that the protrusion suppressing effect of the distal end portion 22a of the glass run channel upper edge portion 22 is sufficiently improved.

As shown in fig. 16A, instead of directly contacting the contact portion 42a of the hard member 40 with the other edge 28bf of the lower wall cutout portion 28b provided in the glass run upper edge portion 22 in the vehicle longitudinal direction, the following structure may be employed.

That is, as shown in fig. 7, among the 2 upper lips 27B, the inner upper lip 27B1 remains without a notch immediately in front of the protruding wall portion 35, and as shown in fig. 16B, the lower wall 28 remains without a notch immediately in front of the protruding wall portion 35. In other words, the abutting portion 42a of the hard member 40 is arranged to abut against the other edge 28bf in the vehicle longitudinal direction provided in the lower wall cutout portion 28b of the glass run upper edge portion 22 via the protruding wall portion 35 of the rear side mold portion 24.

Here, the glass run attachment plate portion 117 (metal), the hard member 40 (hard resin: POM), and the lower wall 28 (hard resin: talc addition PP) are all hard members, and are hardly deformed by flexing in the front-rear direction, but the protruding wall portion 35 of the rear side mold portion 24 is molded from a material slightly softer than the lower wall 28, and therefore can be slightly deformed by flexing in the front-rear direction.

Therefore, even when there is a deviation in the shape and size of the front door 101, a deviation in the shape and size of the glass run channel 20, a deviation in the shape and size of the hard member 40, a deviation in the assembly of the front door 101, or the like, the assembly is easy.

Further, as shown in fig. 16A and 16B, the abutting portion 42a of the hard member 40 may be abutted (zero contact) with one edge 114cb of the lower cutout 114c of the glass run channel attachment plate 117 in the vehicle longitudinal direction, the rear surface 43B of the locking portion 43 of the hard member 40, and the other edge 28bf of the lower cutout 28B of the glass run channel upper side 22 in the vehicle longitudinal direction, or the rear side surface 35B of the protruding wall 35 of the rear side mold forming portion 24, respectively, but the amount of the abutting portion 42a of the hard member 40 may be set in consideration of the variation in the shape and size of the front door 101, the variation in the shape and size of the glass run channel 20, the variation in the assembly of the front door 101, and the like, and the amount of the gap may be set to be further varied (not shown) with respect to the abutting portion 42a facing the other edge 28bf of the lower cutout 28B of the glass run channel upper side 22 in the vehicle longitudinal direction, or the rear side surface 35B of the protruding wall 35 of the rear side mold forming portion 24. The gap by a certain amount is preferably set smaller than the allowable size of the positional displacement (movement) of the upper edge 22 of the glass run.

(removal of hard Member)

When the glass run channel 20 is removed from the window frame 110, the locking claw portions 44a, 44a of the hard member 40 need to be pulled out from the locking hole 124 c. In the present embodiment, first, the garnish 130 is set to a detached state from the state shown in fig. 11. Next, for example, the distal end of a tool such as a radio pliers is inserted into the holding cylinder portion 44 from the outside of the cabin, and the operated portions 44b and 44b are pinched in the directions approaching each other, whereby the locking claw portions 44a and 44a are separated from the edge portions of the locking hole 124c, and the locked state of the locking claw portions 44a and 44a is released, so that the locking claw portions 44a and 44a can be pulled out from the locking hole 124 c.

(effects of the embodiment)

As described above, since the hard member 40 is detachably attached to the rear side mold forming portion 24, the moldability of the rear side mold forming portion 24 is not deteriorated, and the degree of freedom in setting the cross-sectional shape of the glass run upper edge portion 22 and selecting the material can be improved. Further, the abutting portion 42a of the hard member 40 abuts against the other edge 28bf of the lower wall cutout portion 28b provided in the lower wall 28 of the glass run channel upper edge portion 22 in the vehicle longitudinal direction from the rear, and the locking portion 43 of the hard member 40 abuts against and is locked to the other edge 114cb of the lower side cutout portion 114c of the glass run channel mounting plate portion 117 in the vehicle longitudinal direction from the other side in the vehicle longitudinal direction, so that the projection of the distal end portion 22a of the glass run channel upper edge portion 22 in one direction (rear) in the vehicle longitudinal direction can be suppressed.

(modification of embodiment)

As shown in fig. 9 and 7, an upper side plate portion 24a of the rear side mold portion 24 is connected to the vehicle interior side of the inner end 27e of the upper plate portion 27, and an inner side plate portion 24b extending downward from the vehicle interior side end of the upper side plate portion 24a is provided. As shown in fig. 7, 16A, and 16B, the front end 24B1 of the inner plate portion 24B is disposed between the rear wall portion 36 and the first wall portion 37 at a position closer to the first wall portion 37, and after the glass run 20 is mounted to the front door 101, the rear end 117e of the glass run mounting plate portion 117 is disposed at a position further rearward than the second wall portion 38.

In such a positional relationship, when the glass run rear side mold forming portion 24 is mounted on the glass run mounting plate portion 117, the rear end 117e of the glass run mounting plate portion 117 is assembled so as to be inserted from a position forward of the front end 24b1 of the inner plate portion 24b of the rear side mold forming portion 24, and therefore the mounting operator of the glass run 20 is careful not to interfere with the glass run mounting plate portion 117 by the locking portion 43, and at the same time, is mounted in a state where the upper notch portion 115 and the lower notch portion 114 cannot be directly visually recognized with the locking portion 43 of the hard member 40.

For example, in fig. 17, when the glass run channel 20 is attached to the window frame 110, the locking portion 43 of the hard member 40 enters the recess 124d of the vertical side outer panel 124. That is, the upper portion of the longitudinal side outer panel 124 is formed with: an inclined surface 124d1 inclined toward the vehicle interior side in an upward direction; and a curved surface 124d2 that is connected to an upper end portion of the inclined surface 124d1 and that is curved toward the outside of the vehicle cabin in an upward direction, and that has a concave portion 124d that is greatly recessed toward the inside of the vehicle cabin.

On the other hand, when the glass run channel 20 is attached to the window frame 110, the hard member 40 is held by the rear side mold forming portion 24 of the glass run channel 20, and the hard member 40 is attached together with the glass run channel 20, and therefore, as described above, the glass run channel 20 is attached by the attachment worker in a state where the upper notched portion 115 and the lower notched portion 114 cannot be directly visually inspected with the locking portion 43 of the hard member 40, and when the locking portion 43 enters the lower side of the curved surface 124d2 located at the upper portion of the concave portion 124d, it may be difficult to confirm whether or not the hard member 40 is assembled at the normal position (shown in fig. 9).

Here, the modification shown in fig. 18 and 19 is to eliminate this, and an inner protruding portion 42e is formed on the vehicle interior surface of the upper side portion 42. The inner protruding portion 42e is constituted by a rib protruding toward the vehicle interior side and extending in the up-down direction, and the protruding amount toward the vehicle interior side is set to be larger than the rib 42d, the abutment portion 42b, and the rear protruding portion 42c shown in fig. 13.

The inner protruding portion 42e is located at a front-rear direction intermediate portion of the upper portion 42, and is separated rearward from the abutting portion 42b and separated from the front protruding portion 42 c.

The protruding dimension (dimension in the vehicle interior-exterior direction) of the inner protruding portion 42e is set to be maximum in the middle portion in the up-down direction, and is smaller as it approaches the upper end of the inner protruding portion 42e and as it approaches the lower end of the inner protruding portion 42 e. Further, a chamfer 43a is formed on the upper part of the vehicle interior side surface, the upper part of the vehicle exterior side surface, the upper part of the front side surface, and the upper part of the rear side surface of the locking portion 43.

The hard member 40 has the inner protruding portion 42e, and the inner protruding portion 42e abuts against the inclined surface 124d1 of the vertical side outer panel 124 when attached to the window frame 110. Accordingly, the posture of the hard member 40 is controlled to be rotated toward the vehicle exterior side, and therefore, regardless of the assembly mode, even if direct visual confirmation is difficult, the locking portion 43 is difficult to enter the lower side of the curved surface 124d2 of the concave portion 124d constituting the vertical side outer panel 124, and the hard member 40 can be assembled at a normal position.

Further, since the chamfer portion 43a is formed on the upper portion of the locking portion 43, when the locking portion 43 is inserted into the lower notch portion 114c, the upper portion of the locking portion 43 is less likely to be caught by the edge portion of the lower notch portion 114 c. Therefore, the locking portion 43 can be reliably inserted into the lower notch portion 114c and can be reliably locked to the edge portion of the lower notch portion 114 c.

The above embodiments are merely examples in all respects and are not to be construed as limiting. Further, all modifications and variations falling within the equivalent scope of the claims are within the scope of the present utility model.

In the present embodiment, the case where the present utility model is applied to the front door 101 has been described, but the present utility model is not limited to this, and the present utility model can be applied to the rear door 102. In the case of application to the rear door 102, although not shown, the hard member 40 may be provided in the glass run so as to be positioned on the front side of the window frame. This can suppress the front end portion of the upper edge portion of the glass run from protruding forward.
