(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, the symbol FR indicates the front in the longitudinal direction of the vehicle, the symbol IN indicates the inside in the width direction of the vehicle, the symbol OUT indicates the outside in the width direction of the vehicle, and the symbol UP indicates the upper side of the vehicle.

A vehicle side door is made up of an outer panel and an inner panel.
The side door has an upper portion formed with a window-forming opening that is opened and closed by a window glass that moves up and down.
The belt line is a portion of an outer panel provided on a side surface of a vehicle that extends in the front-rear direction of the vehicle along a lower edge of an opening.
A belt molding is attached along the belt line, and the lower edge of the opening in the outer panel is covered by the belt molding.
The belt molding is a molded product made of elastic synthetic resin that extends in the fore-and-aft direction of the vehicle. It protects the lower edge of the opening in the outer panel and improves the appearance, and also functions as a weather strip that comes into contact with the outer surface of the window glass to drain water.
Both ends of the belt molding in the longitudinal direction of the vehicle are attached to sashes located in front and behind the opening of the outer panel.
In this embodiment, a mounting structure for mounting the rear end of the belt molding to the rear sash will be described, although a similar structure may also be used for mounting the front end of the belt molding to the front sash.

As shown in FIG. 1, this mounting structure includes a belt molding mounting portion 10, a grommet 12A, and a claw portion 16.
The belt molding attachment portion 10 is provided on the lower end portion of a rear sash 18 (i.e., an outer panel 19) located on an extension of the belt line.
As shown in FIGS. 1 and 2, the belt molding 14 includes an outer molding portion 20 and a claw portion 16A. In FIG. 1, reference numeral 14A denotes the main body of the belt molding 14 which covers the lower edge of the opening of the outer panel 19.
An engagement portion 16A for engaging the belt molding 14 with the outer panel 19 is provided on an inner portion of the belt molding 14 in the vehicle width direction. A claw portion 16 for engaging with the belt molding attachment portion 10 is provided on a vehicle rear end portion of the belt molding 14. The claw portion 16 is formed by cutting away a part of the engagement portion 16A. In other words, the claw portion 16 is located rearward of the cut portion 1402.
The outer molding portion 20 and the engaging portion 16A are integrally formed.
2, the claw portion 16 includes a vertical plate portion 1602 extending vertically, and a protruding portion 1604 provided at the lower end of the vertical plate portion 1602 and protruding outward in the vehicle width direction. The belt molding 14 is provided with a lip 21 that protrudes inward in the vehicle width direction from the upper end of the outer molding portion 20 and abuts against the outer panel or the window glass. The claw portion 16 extends downward from the upper end of the outer molding portion 20. In other words, the claw portion 16 (protruding portion 1604) is located outward in the vehicle width direction from the inner end of the belt molding 14 in the vehicle width direction.
As shown in FIGS. 1 and 2 , the belt molding attachment portion 10 has a first wall 22 , a second wall 24 , a third wall 26 , and a hole 28 .
The first wall 22 extends in the vertical direction of the vehicle, the second wall 24 extends outward in the vehicle width direction from the lower end of the first wall 22, and the third wall 26 extends obliquely downward and outward in the vehicle width direction from the outer end of the second wall 24 in the vehicle width direction.
The hole portion 28 is provided in the second wall 24 in a rectangular shape when viewed in a plane, and in this embodiment, the hole portion 28 is provided across the entire width of the second wall 24 and extends to the lower end of the first wall 22 and the upper end of the third wall 26.

The grommet 12A is made of an elastic synthetic resin and is attached to the belt molding attachment portion 10 by being inserted into the hole 28 and abutting against the inner surface around the hole 28 of the outer panel 19.
The grommet 12A has a first portion 30 that abuts against the inner surface of the first wall 22, a second portion 32 that abuts against the inner surface of the third wall 26, a claw insertion opening 34 formed between the first portion 30 and the second portion 32, a first abutment portion 36, and a second abutment portion 38. The first abutment portion 36 abuts against the vertical plate portion 1602 of the claw portion 16 inserted into the claw insertion opening 34 to suppress rotation of the belt molding 14 inward in the vehicle width direction, and the second abutment portion 38 abuts against the vertical plate portion 1602 of the claw portion 16 to suppress rotation of the belt molding 14 outward in the vehicle width direction. Rotation inward in the vehicle width direction refers to clockwise rotation in Figures 2 and 4, and rotation outward in the vehicle width direction refers to counterclockwise rotation in Figures 2 and 4. Note that Figures 2 and 4 are views of the left side of the vehicle as viewed from the rear.

As shown in Figs. 1 and 2, the grommet 12A includes a plate-shaped inner member 40, an outer member 42 located outside the inner member 40 in the vehicle width direction, and two connecting members 44 connecting them.
The first portion 30 is formed by a step portion 4002 that protrudes upward from the vehicle width direction inner end of the upper end of the inner member 40. The second abutment portion 38 is formed on the vehicle width direction outer surface of the wall portion of the inner member 40 that is formed to extend downward from the first portion 30.

The two connecting members 44 connect both ends of the inner member 40 and the outer member 42 in the fore-and-aft direction of the vehicle, and the claw insertion opening 34 is formed into a rectangular hole by the inner member 40, the outer member 42, and the two connecting members 44.
The outer member 42 has an upper portion provided with an engagement groove that opens downward, and the lower edge (the outer edge of the hole 28 in the vehicle width direction) of the hole 28 located in the third wall 26 is engaged with the engagement groove. In addition, a bulge 43 that bulges outward in the vehicle width direction is provided at the lower end of the outer member 42. A bulge 43 has a lower end that is provided with an engagement surface 3204 that engages with the protrusion 1604 of the claw 16 of the belt molding 14. The bulge 43 forms the second part 32.
The first contact portion 36 is formed on an inner surface of the second portion 32 in the vehicle width direction.
Both ends of the belt molding 14 in the vehicle front-rear direction are closed by caps (not shown). The caps close the openings in the vehicle front-rear direction at both ends of the belt molding 14 in the vehicle front-rear direction, and have projections and recesses for engaging with the belt molding 14, but do not have claws to be inserted into the holes 28.

Next, the effects will be described.
The grommet 12A is bent so that the lower portion of the outer member 42 and the lower portion of the inner member 40 are brought closer to each other, and then inserted into the hole 28.
By this insertion, the first portion 30 abuts against the upper edge of the hole 28 and the second portion 32 abuts against the lower edge of the hole 28, thereby attaching the grommet 12A to the hole 28.
Once the grommet 12A has been attached to the hole 28, the claw portion 16 of the belt molding 14 is inserted into the claw insertion hole 34 so that the protrusion 1604 is engaged with the engaged surface 3204 at the lower end of the second portion 32.
In this state, the first contact portion 36 contacts the outer surface of the vertical plate portion 1602 of the belt molding 14 in the vehicle width direction, and the second contact portion 38 contacts the inner surface of the vertical plate portion 1602 in the vehicle width direction.
The first abutment portion 36 abuts against the outer surface of the vertical plate portion 1602, thereby preventing the upper part of the belt molding 14 from rotating inward in the vehicle width direction, and the second abutment portion 38 abuts against the inner surface of the vertical plate portion 1602, thereby preventing the upper part of the belt molding 14 from rotating outward in the vehicle width direction.

According to this embodiment, a grommet 12A is provided which is inserted into a hole 28 formed in the second wall 24 of the outer panel 19 and abuts against the inner surface of the outer panel 19, and the belt molding 14 is attached to the outer panel 19 by fitting a claw portion 16 formed integrally with the belt molding 14 into the grommet 12A.
Therefore, unlike the conventional art, it is not necessary to form a claw portion on the cap, which is advantageous in terms of reducing costs.
Furthermore, since the claw portion 16 is formed integrally with the belt molding 14, this is advantageous in improving the positioning accuracy of the belt molding 14 relative to the outer panel 19 compared to when the belt molding 14 and the claw portion 16 are separate bodies.

In addition, in this embodiment, the first part 30 of the grommet 12A abuts against the inner surface of the first wall 22, thereby preventing the grommet 12A from rotating outward in the vehicle width direction, and the second part 32 abuts against the inner surface of the third wall 26, thereby preventing the grommet 12A from rotating inward in the vehicle width direction.
In addition, the first abutment portion 36 of the grommet 12A abuts against the claw portion 16, thereby suppressing rotation of the belt molding 14 inward in the vehicle width direction, and the second abutment portion 38 abuts against the claw portion 16, thereby suppressing rotation of the belt molding 14 outward in the vehicle width direction.
Therefore, both the grommet 12A attached to the outer panel 19 and the belt molding 14 attached to the grommet 12A can be prevented from rotating inward or outward in the vehicle width direction, which is advantageous in attaching the belt molding 14 to the outer panel 19 in a stably manner without any rattling.

In addition, in this embodiment, the first abutment portion 36 is the vehicle width direction inner surface of the second portion 32, and the second abutment portion 38 is the vehicle width direction outer surface of a wall portion formed extending downward from the first portion 30.
Therefore, the first abutment portion 36 and the second abutment portion 38 can support the claw portion 16 of the belt molding 14 from both sides in the vehicle width direction, which further prevents the belt molding 14 from rotating inward or outward in the vehicle width direction, making it more advantageous for stably attaching the belt molding 14 to the outer panel 19 without any rattling.

In addition, in this embodiment, the claw portion 16 is located on the outer side of the vehicle width direction from the inner end of the belt molding 14 in the vehicle width direction, so that the claw portion 16 is prevented from hitting the outer panel 19 and damaging the outer panel 19 when attaching the belt molding 14 to the outer panel 19. Therefore, there is no need to take care not to damage the outer panel 19 when attaching the belt molding, as in the conventional case, which is advantageous in terms of improving the efficiency of the attachment work.

Second Embodiment
Next, a second embodiment will be described with reference to FIGS.
In the following description of the embodiment, the same members and parts as those in the first embodiment are denoted by the same reference numerals, and their description will be simplified or omitted, with the focus being on the differences.
A wide portion 1610 is provided on the upper portion of the vertical plate portion 1602 of the claw portion 16 of the belt molding 14 .
The grommet 12B is attached to the rear sash 18 by being inserted into the hole 28 and abutting against the inner surface around the hole 28 of the outer panel 19, as in the first embodiment.
The grommet 12B has a first portion 30 abutting against the inner surface of the first wall 22, a second portion 32 abutting against the inner surface of the third wall 26, a third portion 46 abutting from the lower end of the outer surface of the first wall 22 to the outer surface of the second wall 24, a claw insertion opening 34 formed between the first portion 30 and the second portion 32, a first abutment portion 36 that suppresses rotation of the belt molding 14 inward in the vehicle width direction, and a second abutment portion 38 that suppresses rotation of the belt molding 14 outward in the vehicle width direction.

More specifically, the grommet 12B includes a pair of arm portions 48 spaced apart in the vehicle front-rear direction. The pair of arm portions 48 extend inward in the vehicle width direction from a main body plate portion 50 that extends in the vehicle front-rear direction.
A recess 52 is provided at a location on the inside of the vehicle width direction in the middle of the main plate portion 50 in the vehicle fore-and-aft direction, which is recessed outward in the vehicle width direction and prevents interference with the protruding portion 1604 of the claw portion 16 of the belt molding 14.
Second contact portions 38 are provided in front of and behind the recess 52 of the main body plate portion 50. The second contact portions 38 extend downward from inner ends of the main body plate portion 50 in the vehicle width direction in front of and behind the recess 52.
A pair of panel landing portions 54 extending in a curved shape are provided on the outer sides of the pair of arm portions 48. The panel landing portions 54 are located in the middle of the pair of arm portions 48 in the vehicle width direction, with their upper portions extending in the vehicle up-down direction and their lower portions extending in the vehicle width direction, and the upper portions abut against the first wall 22 and the lower portions abut against the second wall 24.
The main body plate portion 50 and the pair of arm portions 48 form a claw insertion opening 34 into which the claw portion 16 of the belt molding 14 is inserted, the claw insertion opening 34 being open on the inner side in the vehicle width direction.
As shown in Figure 4 (D), a protrusion that protrudes upward is provided at the tip of the pair of arm portions 48, and this protrusion forms a first portion 30 that engages with the inner surface of the upper opening edge of the hole portion 28 in the first wall 22.

3, the claw portion 16 has a wide portion 1610, the width of which in the vehicle front-rear direction is increased, on an upper portion of the vertical plate portion 1602. The wide portion 1610 is provided forward of the protruding portion 1604 and rearward of the vehicle.
As shown in FIG. 4C , the second contact portion 38 is provided so as to be able to contact the wide portion 1610 .
As shown in FIG. 4A, a downwardly extending elastic piece 56 is provided at the middle portion of the main body plate portion 50 in the vehicle front-rear direction.
4B, the elastic piece 56 includes a plate portion 5602 extending downward from the main plate portion 50, and a bulging portion 5604 bulging outward in the vehicle width direction at the lower end of the plate portion 5602. The plate portion 5602 also includes an upper plate portion 5602A extending in the vehicle up-down direction and positioned outward in the vehicle width direction from the hole portion 28, an intermediate plate portion 5602B extending downward and inward in the vehicle width direction from the lower end of the upper plate portion 5602A and capable of abutting against the outer edge of the hole portion 28, and a lower plate portion 5602C extending downward from the lower end of the intermediate plate portion 5602B and provided with the bulging portion 5604.
The first abutment portion 36 is formed on the inner surface of the plate portion 5602 in the vehicle width direction, and abuts against the lower portion of the vertical plate portion 1602 of the claw portion 16 .
The second portion 32 is formed by a bulge portion 5604 and abuts against the inner surface of the third wall 26 .

Next, the effects will be described.
The elastic piece 56 is inserted into the hole 28 from above, and the pair of arm portions 48 are moved from the outer side in the vehicle width direction to the inner side in the vehicle width direction and inserted into the hole 28 .
Then, the first part 30 is abutted against the inner surface of the upper edge of the hole part 28, the second part 32 is abutted against the inner surface of the third wall 26, and the third part 46 is abutted against the outer surfaces of the first wall 22 and the second wall 24, thereby attaching the grommet 12B to the hole part 28.
Once the grommet 12B is attached to the hole 28, the claw portion 16 of the belt molding 14 is inserted into the claw insertion hole 34 and the protrusion 1604 is engaged with the engaged surface 3204 at the lower end of the second portion 32.
In this state, the first abutment portion 36 abuts against the outer surface of the lower part of the vertical plate portion 1602 of the claw portion 16 of the belt molding 14 , and the second abutment portion 38 abuts against the outer surface of the upper wide portion 1610 of the vertical plate portion 1602 .
The first abutment portion 36 abuts against the outer surface of the lower part of the vertical plate portion 1602, thereby preventing the upper part of the belt molding 14 from rotating inward in the vehicle width direction, and the second abutment portion 38 abuts against the outer surface of the wide portion 1610, thereby preventing the upper part of the belt molding 14 from rotating outward in the vehicle width direction.
In addition, the third portion 46 abuts against the outer surfaces of the first wall 22 and the second wall 24, thereby preventing the upper portion of the belt molding 14 from rotating outwardly or inwardly in the vehicle width direction, and also preventing the grommet 12B from falling into the hole portion 28.

In the second embodiment as described above, the same effects as in the first embodiment are achieved.
In addition, in the second embodiment, since no wall (second abutment portion 38) is provided on the inner side of the claw portion 16 in the vehicle width direction, it is less likely to hinder the movement of the claw portion 16 in the vehicle width direction, which is more advantageous in terms of improving the efficiency of work on the hole portion 28 of the claw portion 16.
