JP 2003-200789 A

Meanwhile, vehicle exterior parts such as back door finishers are fastened to vehicle body panels with bolts. For example, vehicle exterior parts are shipped with the bolts assembled to a body part made of resin. In such vehicle exterior parts, different bolts may be used depending on the location where they are used. For example, bolts with cap nuts screwed onto the tips are used in locations that may be visible from the outside, and bolts with regular hex nuts screwed onto the tips are used in locations that may not be visible from the outside. For this reason, if the bolts are installed in the wrong position, the vehicle exterior part cannot be fastened to the vehicle body panel.

The present invention was made in consideration of the above-mentioned problems, and aims to prevent the bolts from being attached in the wrong position in a vehicle exterior part that is fastened to a body panel by bolts.

The present invention adopts the following configuration as a means for solving the above problems.

The first aspect of the present invention is an exterior vehicle part that is fastened to a vehicle body panel, the exterior vehicle part having a design wall having a design surface on at least a portion of the exterior wall surface, and a first fastening portion and a second fastening portion that are provided on the interior wall surface of the design wall and fastened to the vehicle body panel, the first fastening portion comprising a first fastening wall having a bolt insertion notch that allows the shank of a bolt to enter and exit in the radial direction of the shank, a pair of first panel opposite side protrusions that protrude from the first fastening wall toward the vehicle body panel and define the dimensions of an object that can enter the space on the opposite side of the first fastening wall to the vehicle body panel, and a pair of first fastening wall opposite side protrusions that protrude from the first fastening wall toward the vehicle body panel and define the dimensions of an object that can enter the space on the opposite side of the first fastening wall to the vehicle body panel. The second fastening portion has a second fastening wall having a bolt insertion notch through which the shank of a bolt can enter and exit in the radial direction of the shank, and a pair of second panel opposite side protrusions that protrude from the second fastening wall to the side opposite the body panel and that define the size of an object that can enter the space on the opposite side of the second fastening wall to the body panel, and the distance between one of the first panel opposite side protrusions of the first fastening portion and the other first panel opposite side protrusion is greater than the distance between one of the second panel opposite side protrusions of the second fastening portion and the other second panel opposite side protrusion.

The second aspect of the present invention employs a configuration similar to that of the first aspect, in which a first bolt has a shaft portion inserted through the bolt insertion notch and attached to the first fastening portion, and a second bolt has a shaft portion inserted through the bolt insertion notch and attached to the second fastening portion.

The third aspect of the present invention is a method for manufacturing a vehicle having a first bolt in the second aspect, the first bolt having a first shaft portion which is a shaft portion inserted into the bolt insertion notch of the first fastening portion, a first head plate which is provided so as to bulge radially from the first shaft portion toward the first shaft portion and is disposed in the space of the first fastening wall of the first fastening portion on the opposite side to the vehicle body panel, and a first intermediate portion plate which is provided so as to bulge radially from the first shaft portion toward the first shaft portion at a position closer to the tip of the first shaft portion on the vehicle body panel side than the first head plate and is disposed in the space of the first fastening wall of the first fastening portion on the vehicle body panel side, and the second bolt having a second shaft portion which is a shaft portion inserted into the bolt insertion notch of the second fastening portion, a second head plate which is provided so as to bulge radially from the second shaft portion toward the second shaft portion and is disposed in the space of the second fastening wall of the second fastening portion on the opposite side to the vehicle body panel, and a first intermediate portion plate which is provided so as to bulge radially from the second shaft portion toward the first shaft portion at a position closer to the tip of the first shaft portion on the vehicle body panel side than the first head plate and is disposed in the space of the first fastening wall of the first fastening portion on the opposite side to the vehicle body panel, The second intermediate portion plate is provided at a position close to the tip on the vehicle body panel side, bulging out in the radial direction from the second shaft portion, and is disposed in the space on the vehicle body panel side of the second fastening wall of the second fastening portion. The width dimension of the second intermediate portion plate as viewed from the direction of entry of the second fastening wall into the space on the vehicle body panel side is larger than the distance between one of the first panel side protrusions of the first fastening portion and the other first panel side protrusion, the width dimension of the first head plate as viewed from the direction of entry of the first fastening wall into the space on the opposite side of the vehicle body panel is larger than the distance between one of the second panel opposite side protrusions of the second fastening portion and the other second panel opposite side protrusion, and the width dimension of the second head plate as viewed from the direction of entry of the second fastening wall into the space on the opposite side of the vehicle body panel is smaller than the distance between one of the second panel opposite side protrusions of the second fastening portion and the other second panel opposite side protrusion.

The fourth aspect of the present invention is the third aspect, in which the first intermediate portion plate and the second intermediate portion plate are indirectly or directly abutted against the vehicle body panel and are circular washers.

However, the present invention is not limited to this.

Figure 1 is a schematic diagram of a vehicle 100 equipped with a back door finisher 1 (vehicle exterior part) of this embodiment, viewed from the rear. As shown in this figure, the back door finisher 1 of this embodiment is an exterior part located at the rear of the vehicle. An openable back door panel 101 (vehicle body panel) is provided at the rear of the vehicle 100, and the back door finisher 1 of this embodiment is fixed to the back door panel 101.

Figure 2 is a schematic perspective view of the back door finisher 1 of this embodiment, as viewed from the rear side. Also, Figure 3 is a cross-sectional view taken along line A-A in Figure 2. As shown in these figures, the back door finisher 1 of this embodiment comprises a finisher main body 2, a rubber member 3, and a bolt 4, which are formed by assembling these together.

The finisher body 2 is integrally formed by injection molding of resin, and as shown in Figures 2 and 3, has a decorative wall 2a, an upper edge wall 2b, a lower edge wall 2c, a positioning portion 2d, and an attachment portion 2e. In the following description, the space surrounded by the decorative wall 2a, the upper edge wall 2b, and the lower edge wall 2c is referred to as the inside of the finisher body 2.

The decorative wall 2a is a portion in which the outer wall surface 2a1 is a decorative surface visible from the outside, and the outer wall surface 2a1 is fixed in a position facing the rear of the vehicle 100 except for the upper end portion 2a2 and the lower end portion 2a3. The decorative wall 2a is formed in an elongated shape extending in the vehicle width direction of the vehicle 100. In addition, the upper end portion 2a2 and the lower end portion 2a3 of the decorative wall 2a are bent toward the back door panel 101. The inner wall surface 2a4 of this decorative wall 2a is provided with a single positioning portion 2d and multiple mounting portions 2e, as shown in FIG. 2.

The upper edge wall 2b is a portion that protrudes from the upper end 2a2 of the decorative wall 2a toward the back door panel 101 (i.e., toward the front of the vehicle 100). In this embodiment, the upper edge wall 2b protrudes horizontally and extends along the vehicle width direction (the direction in which the decorative wall 2a extends), which is a direction that intersects with the protruding direction (the front-rear direction of the vehicle 100).

The lower edge wall 2c is a portion that protrudes from the lower end 2a3 of the decorative wall 2a toward the back door panel 101 (i.e., toward the front of the vehicle 100). In this embodiment, the lower edge wall 2c protrudes horizontally and extends along the vehicle width direction (the direction in which the decorative wall 2a extends), which is a direction that intersects with the protruding direction (the front-rear direction of the vehicle 100).

As shown in FIG. 2, the positioning portion 2d is provided on the inner wall surface 2a4 of the design wall 2a, and has a pin portion that protrudes toward the back door panel 101. This positioning portion 2d is a portion for aligning the position of the back door finisher 1 relative to the back door panel 101 when attaching the back door finisher 1 of this embodiment to the back door panel 101. Before fastening the back door finisher 1 to the back door panel 101 with a bolt (not shown), the position of the back door finisher 1 relative to the back door panel 101 is determined by inserting the pin portion of the positioning portion 2d into a grommet attached to the back door panel 101.

The mounting portion 2e is attached to the back door panel 101 by a clip (not shown) or a bolt (described later). As shown in FIG. 2, a plurality of mounting portions 2e are provided on the inner wall surface 2a4 of the decorative wall 2a. These mounting portions 2e are arranged in the extension direction of the back door finisher 1 (the extension direction of the decorative wall 2a, which is the vehicle width direction). The mounting portions 2e will be described in detail later.

The rubber member 3 is a cushioning member attached to the upper edge wall 2b and the lower edge wall 2c via an adhesive sheet. The rubber member 3 is interposed between the finisher main body 2 and the back door panel 101 to prevent contact between the finisher main body 2 and the back door panel 101. Such rubber members 3 are made of soft resin, and multiple members are attached to each of the upper edge wall 2b and the lower edge wall 2c.

The bolt 4 is a part for fastening the back door finisher 1 of this embodiment to the back door panel 101. A nut (not shown) is screwed onto the bolt 4. The bolt 4 is screwed onto the nut, and the mounting portion 2e and the back door panel 101 are clamped between the bolt 4 and the nut, thereby fastening the back door finisher 1 of this embodiment to the back door panel 101. Details of the bolt 4 will be described later.

Next, the mounting portion 2e and the bolt 4 will be described in detail with reference to Figures 4 to 7. In the back door finisher 1 of this embodiment, multiple types of mounting portions 2e are provided and multiple types of bolts 4 are used. Specifically, a first bolt 5 shown in Figure 4 and a second bolt 6 shown in Figure 5 are used as the bolts 4. Furthermore, the mounting portion 2e includes a first fastening portion 7 to which the first bolt 5 is attached and a second fastening portion 8 to which the second bolt 6 is attached. In addition, the mounting portion 2e includes a locking portion 9 to which a clip (not shown) is attached.

Figure 4 shows the external appearance of the first bolt 5, with (a) being a plan view and (b) being a side view. As shown in these figures, the first bolt 5 has a shaft portion 5a (first shaft portion), a rotation prevention portion 5b (first head plate), and a washer 5c (first mid-section plate).

The shaft portion 5a is a rod member having a male thread formed on at least the peripheral surface of the tip 5a1 side for screwing a nut. When the back door finisher 1 of this embodiment is fixed to the back door panel 101, the first bolt 5 is arranged with the tip 5a1 of the shaft portion 5a facing the back door panel 101 side. The axis of this shaft portion 5a is the axis L1 of the first bolt 5. The diameter of the shaft portion 5a is set to a dimension that allows the shaft portion 5a to be inserted into the bolt insertion notch 7a1 of the first fastening portion 7 described later. In the following description, the end of the shaft portion 5a opposite the tip 5a1 is referred to as the rear end. When the first bolt 5 is attached to the first fastening portion 7, such a shaft portion 5a is inserted into the bolt insertion notch 7a1 of the first fastening portion 7 described later.

The rotation prevention part 5b is connected to the rear end of the shaft part 5a. The rotation prevention part 5b is a plate-shaped part that bulges out from the shaft part 5a in the radial direction of the shaft part 5a. As shown in FIG. 4(a), the rotation prevention part 5b is formed in a rectangular shape having a pair of long sides 5b1 and a pair of short sides 5b2 when viewed from the direction along the axis L1. In this embodiment, the direction along the long side 5b1 of the rotation prevention part 5b is the movement direction when the first bolt 5 is attached to and detached from the first fastening part 7. The rotation prevention part 5b is formed in a plate shape whose thickness dimension (dimension in the direction along the axis L1) is smaller than the short side 5b2.

When the first bolt 5 is attached to the first fastening portion 7, the rotation prevention portion 5b is disposed in the space on the opposite side of the back door panel 101 from the fastening wall 7a of the first fastening portion 7, which will be described later. When the nut of the shaft portion 5a of the first bolt 5 is attached, the rotation prevention portion 5b abuts against a part of the first fastening portion 7, thereby preventing the first bolt 5 from rotating in the circumferential direction around the axis L1.

As described above, the direction along the long side 5b1 of the rotation prevention portion 5b is the direction of movement when the first bolt 5 is attached to or detached from the first fastening portion 7. Therefore, in this embodiment, the width dimension D1 of the rotation prevention portion 5b when viewed from the direction of entry into the space on the opposite side of the fastening wall 7a from the back door panel 101 is the separation dimension of the long side 5b1 (the length dimension of the short side 5b2).

The washer 5c is located closer to the tip 5a1 of the shaft portion 5a than the anti-rotation portion 5b. The washer 5c is provided so as to bulge from the shaft portion 5a in the radial direction of the shaft portion 5a, and is formed in a circular shape when viewed in the direction along the axis L1. The washer 5c is formed in a disk shape with a thickness dimension (dimension in the direction along the axis L1) smaller than its diameter.

When the first bolt 5 is attached to the first fastening portion 7, the washer 5c is disposed in the space on the back door panel 101 side of the fastening wall 7a of the first fastening portion 7, which will be described later. The washer 5c is abutted against the surface of the back door panel 101 via, for example, a watertight seal washer (not shown) as necessary. In other words, the washer 5c is abutted directly or indirectly against the surface of the back door panel 101.

As described above, the direction along the long side 5b1 of the rotation prevention portion 5b is the direction of movement when the first bolt 5 is attached to and detached from the first fastening portion 7. Therefore, in this embodiment, the width dimension D2 of the washer 5c when viewed from the direction in which the fastening wall 7a enters the space on the back door panel 101 side is the diameter dimension of the washer 5c.

Figure 5 shows the external appearance of the second bolt 6, with (a) being a plan view and (b) being a side view. As shown in these figures, the second bolt 6 has a shaft portion 6a (second shaft portion), a rotation prevention portion 6b (second head plate), and a washer 6c (second mid-section plate).

The shaft portion 6a is a rod member having a male thread formed on at least the peripheral surface of the tip 6a1 side for screwing a nut. When the back door finisher 1 of this embodiment is fixed to the back door panel 101, the second bolt 6 is arranged with the tip 6a1 of the shaft portion 6a facing the back door panel 101 side. The axis of this shaft portion 6a is the axis L2 of the second bolt 6. The diameter of the shaft portion 6a is set to a dimension that allows the shaft portion 6a to be inserted into the bolt insertion notch 8a1 of the second fastening portion 8 described later. In the following description, the end of the shaft portion 6a opposite to the tip 6a1 is referred to as the rear end. When the second bolt 6 is attached to the second fastening portion 8, such a shaft portion 6a is inserted into the bolt insertion notch 8a1 of the second fastening portion 8 described later.

The rotation prevention part 6b is connected to the rear end of the shaft part 6a. The rotation prevention part 6b is a plate-shaped part that bulges out from the shaft part 6a in the radial direction of the shaft part 6a. As shown in FIG. 5(a), the rotation prevention part 6b is formed in a rectangular shape having a pair of long sides 6b1 and a pair of short sides 6b2 when viewed from the direction along the axis L2. In this embodiment, the direction along the long side 6b1 of the rotation prevention part 6b is the movement direction when the second bolt 6 is attached to and detached from the second fastening part 8. The rotation prevention part 6b is formed in a plate shape whose thickness dimension (dimension in the direction along the axis L2) is smaller than the short side 6b2.

When the second bolt 6 is attached to the second fastening portion 8, the rotation prevention portion 6b is disposed in the space on the opposite side of the back door panel 101 from the fastening wall 8a of the second fastening portion 8, which will be described later. When a nut is attached to the shaft portion 6a of the second bolt 6, the rotation prevention portion 6b abuts against a part of the second fastening portion 8, thereby preventing the second bolt 6 from rotating in the circumferential direction around the axis L2.

As described above, the direction along the long side 6b1 of the rotation prevention portion 6b is the direction of movement when the second bolt 6 is attached to or detached from the second fastening portion 8. Therefore, in this embodiment, the width dimension D3 of the rotation prevention portion 6b when viewed from the direction of entry into the space on the opposite side of the fastening wall 8a from the back door panel 101 is the distance dimension of the long side 6b1 (the length dimension of the short side 6b2).

The washer 6c is located closer to the tip 6a1 of the shaft portion 6a than the anti-rotation portion 6b. The washer 6c bulges outward from the shaft portion 6a in the radial direction of the shaft portion 6a and is formed in a circular shape when viewed in the direction along the axis L2. The washer 6c is formed in a disk shape with a thickness dimension (dimension in the direction along the axis L2) smaller than its diameter.

When the second bolt 6 is attached to the second fastening portion 8, the washer 6c is disposed in the space on the back door panel 101 side of the fastening wall 8a of the second fastening portion 8, which will be described later. The washer 6c is abutted against the surface of the back door panel 101 via, for example, a watertight seal washer (not shown) as necessary. In other words, the washer 6c is abutted directly or indirectly against the surface of the back door panel 101.

As described above, the direction along the long side 6b1 of the rotation prevention portion 6b is the direction of movement when the second bolt 6 is attached to or detached from the second fastening portion 8. Therefore, in this embodiment, the width dimension D4 of the washer 6c when viewed from the direction in which the fastening wall 8a enters the space on the back door panel 101 side is the diameter dimension of the washer 6c.

Comparing the first bolt 5 and the second bolt 6, for example, at least one of the length and diameter dimensions of the shaft portion 5a and the shaft portion 6a differs depending on the type of nut to be attached. In other words, the first bolt 5 and the second bolt 6 are different types of bolts and cannot be substituted for each other.

In this embodiment, the first bolt 5 and the second bolt 6 have different shapes when viewed from the mounting direction to the mounting portion 2e. Specifically, the width dimension D4 of the washer 6c of the second bolt 6 is larger than the width dimension D3 of the washer 5c of the first bolt 5, and is larger than the distance Dc between one panel side protrusion 7c and the other panel side protrusion 7c of the first fastening portion 7 described later.

Furthermore, the width dimension D1 of the rotation prevention portion 5b of the first bolt 5 is larger than the width dimension D2 of the rotation prevention portion 6b of the second bolt 6, and is larger than the distance Db between one panel opposite protrusion 8b and the other panel opposite protrusion 8b of the second fastening portion 8 described below. Also, the width dimension D2 of the rotation prevention portion 6b of the second bolt 6 is smaller than the distance Db between one panel opposite protrusion 8b and the other panel opposite protrusion 8b of the second fastening portion 8.

Figure 6 shows the external appearance of the first fastening portion 7, where (a) is a plan view seen from the normal direction of the inner wall surface 2a4 of the decorative wall 2a, and (b) is a side view seen from the direction of arrow A in (a). The first fastening portion 7 has a fastening wall 7a (first fastening wall), a panel opposite side protrusion 7b (first panel opposite side protrusion), and a panel side protrusion 7c (first panel side protrusion).

The fastening wall 7a is a wall portion to which the first bolt 5 is attached, and is disposed approximately parallel to the back door panel 101 (the inner wall surface 2a4 of the decorative wall 2a). The anti-rotation portion 5b of the first bolt 5 abuts against this fastening wall 7a from the side opposite the back door panel 101. By screwing a nut onto the tip 5a1 side of the first bolt 5, the first bolt 5 is pulled toward the back door panel 101, and the fastening wall 7a and the surface opposite the back door panel 101 are pressed by the anti-rotation portion 5b.

As shown in FIG. 6(a), the fastening wall 7a has a bolt insertion notch 7a1. The bolt insertion notch 7a1 is a generally C-shaped recess that opens to one side of the fastening wall 7a, which is rectangular in plan view. The opening of the bolt insertion notch 7a1 on one side of the fastening wall 7a is used as an entrance 7a2 for inserting and removing the shaft 5a of the first bolt 5 into and from the bolt insertion notch 7a1. In this embodiment, the entrance 7a2 opens in the direction in which the decorative wall 2a extends (i.e., the vehicle width direction).

The center of the bolt insertion notch 7a1 is circular and slightly larger than the diameter of the shaft portion 5a of the first bolt 5, allowing the shaft portion 5a to be inserted therethrough. A pair of notches 7a3 are provided near the entrance portion 7a2 of the bolt insertion notch 7a1 to prevent the shaft portion 5a inserted in the center from easily coming off the bolt insertion notch 7a1.

The bolt insertion notch 7a1 is formed so that the shaft portion 5a of the first bolt 5 can enter and exit by moving the shaft portion 5a in the radial direction of the shaft portion 5a through the entrance portion 7a2. In other words, in this embodiment, the fastening wall 7a has a bolt insertion notch 7a1 that allows the shaft portion 5a of the first bolt 5 to enter and exit in the radial direction of the shaft portion 5a.

Two panel opposite side protrusions 7b are provided, protruding in the direction opposite the back door panel 101 from the surface of the fastening wall 7a opposite the back door panel 101. These two pair of panel opposite side protrusions 7b are arranged to sandwich the entrance portion 7a2 therebetween, and at least a portion is arranged on the entrance portion 7a2 side of the center of the bolt insertion notch 7a1.

These panel opposite side protrusions 7b determine the dimensions of objects that can enter the space on the opposite side of the fastening wall 7a from the back door panel 101. In other words, the two panel opposite side protrusions 7b prevent objects with dimensions larger than the separation dimension Da between them from entering the space on the opposite side of the fastening wall 7a from the back door panel 101.

In this embodiment, the distance Da between one panel opposite protrusion 7b and the other panel opposite protrusion 7b is greater than the width D1 of the rotation prevention portion 5b of the first bolt 5. Therefore, these panel opposite protrusions 7b allow the rotation prevention portion 5b of the first bolt 5 to enter the space on the opposite side of the fastening wall 7a to the back door panel 101.

These panel opposite side protrusions 7b extend in a straight line along the long side 5b1 of the rotation prevention part 5b arranged in the space on the opposite side of the fastening wall 7a from the back door panel 101. Therefore, when the rotation prevention part 5b tries to rotate in the circumferential direction around the axis L1 of the first bolt 5, the rotation prevention part 5b abuts against the panel opposite side protrusions 7b, preventing the first bolt 5 from rotating around the axis L1.

The panel opposite side protrusions 7b extend to the opposite side of the back door panel 101 until they reach the decorative wall 2a, and are connected to the inner wall surface 2a4 of the decorative wall 2a. These panel opposite side protrusions 7b also function as supports that support the fastening wall 7a so that a certain gap is formed between the fastening wall 7a and the inner wall surface 2a4 of the decorative wall 2a. In this embodiment, the panel opposite side protrusions 7b are connected to the inner wall surface 2a4 of the side wall provided at the end of the decorative wall 2a, for example.

Two panel side protrusions 7c are provided protruding from the surface of the fastening wall 7a on the back door panel 101 side in the direction of the back door panel 101 side. These two panel side protrusions 7c are arranged to sandwich the entrance portion 7a2 between them, and are arranged closer to the entrance portion 7a2 than the center of the bolt insertion notch 7a1. These panel side protrusions 7c determine the size of an object that can enter the space on the back door panel 101 side of the fastening wall 7a. In other words, the two panel side protrusions 7c prevent an object with dimensions larger than the separation dimension Db between them from entering the space on the back door panel 101 side of the fastening wall 7a.

In this embodiment, the distance Db between one panel side protrusion 7c and the other panel side protrusion 7c is smaller than the width dimension D4 of the washer 6c of the second bolt 6. Therefore, these panel side protrusions 7c prevent the washer 6c of the second bolt 6 from entering the space on the back door panel 101 side of the fastening wall 7a.

In addition, in this embodiment, the distance Db between one panel side protrusion 7c and the other panel side protrusion 7c is greater than the width dimension D3 of the washer 5c of the first bolt 5. Therefore, these panel side protrusions 7c allow the washer 5c of the first bolt 5 to enter the space on the back door panel 101 side of the fastening wall 7a.

Figure 7 shows the external appearance of the second fastening portion 8, where (a) is a plan view seen from the normal direction of the inner wall surface 2a4 of the decorative wall 2a, and (b) is a side view seen from the direction of arrow B in (a). The second fastening portion 8 has a fastening wall 8a (second fastening wall) and a panel opposite protrusion 8b (second panel opposite protrusion).

The fastening wall 8a is a wall portion to which the second bolt 6 is attached, and is disposed approximately parallel to the back door panel 101 (the inner wall surface 2a4 of the decorative wall 2a). The anti-rotation portion 6b of the second bolt 6 abuts against this fastening wall 8a from the side opposite the back door panel 101. By screwing a nut onto the tip 5a1 side of the second bolt 6, the second bolt 6 is pulled toward the back door panel 101, and the fastening wall 8a and the surface opposite the back door panel 101 are pressed by the anti-rotation portion 6b.

As shown in FIG. 7(a), the fastening wall 8a is formed with a bolt insertion notch 8a1. The bolt insertion notch 8a1 is a generally C-shaped recess that opens to one side of the fastening wall 8a, which is rectangular in plan view. The opening of the bolt insertion notch 8a1 on one side of the fastening wall 8a is used as an entrance 8a2 for inserting and removing the shaft 6a of the second bolt 6 into and from the bolt insertion notch 8a1. In this embodiment, the entrance 8a2 opens in the direction in which the decorative wall 2a extends (i.e., the vehicle width direction).

The center of the bolt insertion notch 8a1 is circular and slightly larger than the diameter of the shaft 6a of the second bolt 6, allowing the shaft 6a to be inserted therethrough. A pair of notches 8a3 are provided near the entrance 8a2 of the bolt insertion notch 8a1 to prevent the shaft 6a inserted in the center from easily coming off the bolt insertion notch 8a1.

The bolt insertion notch 8a1 is formed so that the shaft portion 6a of the second bolt 6 can enter and exit by moving the shaft portion 6a radially through the entrance portion 8a2. In other words, in this embodiment, the fastening wall 8a has a bolt insertion notch 7a1 that allows the shaft portion 6a of the second bolt 6 to enter and exit in the radial direction of the shaft portion 6a.

Two panel opposite side protrusions 8b are provided, protruding in the direction opposite the back door panel 101 from the surface of the fastening wall 8a opposite the back door panel 101. These two pair of panel opposite side protrusions 8b are arranged to sandwich the entrance portion 8a2 therebetween, and at least a portion is arranged on the entrance portion 8a2 side of the center of the bolt insertion notch 8a1.

These panel opposite side protrusions 8b determine the dimensions of objects that can enter the space on the opposite side of the fastening wall 8a from the back door panel 101. In other words, the two panel opposite side protrusions 8b prevent objects with dimensions larger than the mutual separation dimension Dc from entering the space on the opposite side of the fastening wall 8a from the back door panel 101.

In this embodiment, the distance Dc between one panel opposite protrusion 8b and the other panel opposite protrusion 8b is smaller than the width D3 of the washer 5c of the first bolt 5. Therefore, these panel opposite protrusions 8b prevent the washer 5c of the first bolt 5 from entering the space on the opposite side of the fastening wall 8a to the back door panel 101.

These panel opposite side protrusions 8b extend in a straight line along the long side 6b1 of the rotation prevention portion 6b arranged in the space on the opposite side of the fastening wall 8a from the back door panel 101. Therefore, when the rotation prevention portion 6b tries to rotate in the circumferential direction around the axis L2 of the second bolt 6, the rotation prevention portion 6b abuts against the panel opposite side protrusion 8b, preventing the second bolt 6 from rotating around the axis L2.

The panel opposite side protrusions 8b extend to the opposite side of the back door panel 101 until they reach the decorative wall 2a, and are connected to the inner wall surface 2a4 of the decorative wall 2a. These panel opposite side protrusions 8b also function as supports that support the fastening wall 8a so that a certain gap is formed between the fastening wall 8a and the inner wall surface 2a4 of the decorative wall 2a.

The second fastening portion 8 also has an embedded portion 8c that is embedded between one panel opposite protrusion 8b and the other panel opposite protrusion 8b. This embedded portion 8c is embedded between one panel opposite protrusion 8b and the other panel opposite protrusion 8b so that an opening for inserting the rotation prevention portion 5b of the second bolt 6 remains in the space on the side of the fastening wall 8a opposite the back door panel 101.

In this embodiment, as shown in FIG. 2, of the multiple mounting portions 2e, two mounting portions 2e arranged at each end of the decorative wall 2a in the vehicle width direction are the first fastening portion 7. Also, as shown in FIG. 2, one of the mounting portions 2e (two in total) adjacent to the first fastening portion 7 at each end of the decorative wall 2a in the vehicle width direction is the second fastening portion 8.

When attaching the tailgate finisher 1 of this embodiment to the tailgate panel 101, for example, a clip attached to one of the engagement parts 9 is slidably engaged with the tailgate panel 101, and the pin part of the positioning part 2d is inserted into, for example, a grommet provided on the tailgate panel 101.

By inserting the pin portion into the grommet in this manner, the tailgate finisher 1 of this embodiment is positioned relative to the tailgate panel 101. At this time, the shaft portion 5a of the first bolt 5 attached to the first fastening portion 7 and the shaft portion 6a of the second bolt 6 attached to the second fastening portion 8 are then inserted into a through hole provided in the tailgate panel 101. Then, a nut is screwed onto the shaft portion 5a of the first bolt 5 and the shaft portion 6a of the second bolt 6 to fasten the tailgate finisher 1 to the tailgate panel 101.

The tailgate finisher 1 of this embodiment is an exterior vehicle part that is fastened to the tailgate panel 101, and has a design wall 2a that has a design surface on at least a portion of the outer wall surface 2a1, and a first fastening portion 7 and a second fastening portion 8 that are provided on the inner wall surface 2a4 of the design wall 2a and are fastened to the tailgate panel 101.

The first fastening portion 7 has a fastening wall 7a having a bolt insertion notch 7a1 through which the shaft portion 5a of the first bolt 5 can enter and exit in the radial direction of the shaft portion 5a. The first fastening portion 7 has a pair of panel opposite side protrusions 7b protruding from the fastening wall 7a to the side opposite the back door panel 101. The pair of panel opposite side protrusions 7b determine the size of an object that can enter the space on the side of the fastening wall 7a opposite the back door panel 101. The first fastening portion 7 has a pair of panel side protrusions 7c protruding from the fastening wall 7a to the back door panel 101 side. The pair of panel side protrusions 7c determine the size of an object that can enter the space on the back door panel 101 side of the fastening wall 7a.

The second fastening portion 8 also has a fastening wall 8a having a bolt insertion notch 8a1 through which the shaft 6a of the second bolt 6 can enter and exit in the radial direction of the shaft 6a. The second fastening portion 8 also has a pair of panel opposite side protrusions 8b that protrude from the fastening wall 8a on the side opposite the back door panel 101. The pair of panel opposite side protrusions 8b determine the dimensions of an object that can enter the space on the side of the fastening wall 8a opposite the back door panel 101.

In addition, in the tailgate finisher 1 of this embodiment, the distance Da between one panel opposite protrusion 7b of the first fastening portion 7 and the other panel opposite protrusion 7b is greater than the distance Db between one panel opposite protrusion 8b of the second fastening portion 8 and the other panel opposite protrusion 8b.

According to the tailgate finisher 1 of this embodiment, a first fastening portion 7 and a second fastening portion 8 are provided as portions to be fastened to the tailgate panel 101. The first fastening portion 7 is provided with a pair of panel side projections 7c that protrude toward the tailgate panel 101 side from the fastening wall 7a in which the bolt insertion notch 7a1 is provided. For this reason, by providing a portion (washer 6c) with a width dimension larger than the distance between the panel side projections 7c for the second bolt attached to the second fastening portion 8, it is possible to prevent the second bolt 6 attached to the second fastening portion 8 from being attached to the first fastening portion 7.

In addition, according to the back door finisher 1 of this embodiment, the first fastening portion 7 is provided with a pair of panel opposite side protrusions 7b protruding from the fastening wall 7a having the bolt insertion notch 7a1 to the side opposite the back door panel 101. The second fastening portion 8 is provided with a pair of panel opposite side protrusions 8b protruding from the fastening wall 8a having the bolt insertion notch 8a1 to the side opposite the back door panel 101. Furthermore, the distance Da between one panel opposite side protrusion 7b of the first fastening portion 7 and the other panel opposite side protrusion 7b is larger than the distance Db between one panel opposite side protrusion 8b of the second fastening portion 8 and the other panel opposite side protrusion 8b. Therefore, by providing a portion (washer 5c) for the first bolt 5 attached to the first fastening portion 7 that has a width dimension larger than the separation dimension Db between the panel opposite projections 8b and smaller than the separation dimension Da between the panel opposite projections 7b, the first bolt 5 attached to the first fastening portion 7 can be prevented from being attached to the second fastening portion 8.

In this way, according to the back door finisher 1 of this embodiment, it is possible to prevent the first bolt 5 attached to the first fastening portion 7 from being attached to the second fastening portion 8, and it is possible to prevent the second bolt 6 attached to the second fastening portion 8 from being attached to the first fastening portion 7. Therefore, it is possible to prevent the first bolt 5 and the second bolt 6 from being attached to the wrong position.
