[0008] <First Embodiment> Hereinafter, one embodiment of this disclosure will be described with reference to the drawings.

[0009] Figure 1(a) is a perspective view showing a vehicle C on which the fastening structure 1 of this disclosure is provided, and Figure 1(b) is a top view showing the rear of the vehicle C. As shown in Figure 1(a), the fastening structure 1 comprises a resin member 2 and a sheet metal member 8. The fastening structure 1 is a fastening structure for attaching the resin member 2 to a structure 4. In this embodiment, the resin member 2 is a spoiler attached to the rear of the vehicle C, and the structure 4 is a roof panel that forms the ceiling of the vehicle C. In Figure 1(a), the first direction X corresponds to the width direction of the vehicle C, the second direction Y corresponds to the front-rear direction of the vehicle C, and the third direction Z corresponds to the up-down direction of the vehicle C. The resin member 2 is not limited to a vehicle C, but may also be a member attached to a skeletal structure or panel forming an aircraft, ship, building, or the like.

[0010] As shown in Figure 1(b), the fastening structure 1 of this embodiment includes a first fastening structure 1a and a second fastening structure 1b that is spaced apart from the first fastening structure 1a in the first direction X. However, the fastening structure 1 may consist of three or more structures spaced apart in the first direction X or the second direction Y, depending on the shape or size of the resin member 2 and the structure 4.

[0011] The resin member 2 includes a first resin member 20 and a second resin member 30 positioned on the structure 4 side and facing the first resin member 20 in the third direction Z. Thus, the first resin member 20 and the second resin member 30 form a resin member 2 (spoiler) having a shell structure. In this embodiment, the first resin member 20 is the outer panel of the spoiler and forms the design surface of the vehicle C. The second resin member 30 is the inner panel of the spoiler.

[0012] Multiple sheet metal members 8 are attached to the second resin member 30. Furthermore, the second resin member 30 is fastened to the structure 4 by multiple fastening members 10. In this embodiment, the sheet metal member 8 includes a sheet metal member 8a and a sheet metal member 8b positioned spaced apart from the sheet metal member 8b in the first direction X. The fastening members 10 also include fastening members 10a and fastening members 10b. In the following, the configurations of the first resin member 20, the second resin member 30, the sheet metal member 8, and the fastening members 10 will be described using the sheet metal member 8a and fastening member 10a positioned at the location corresponding to the AA section in Figure 1(b) as an example.

[0013] As shown in Figure 2, the first resin member 20 has a plate-shaped first general portion 21 that extends in the first direction X and the second direction Y, a first folded portion 22 provided at the front end of the first general portion 21 (opposite direction of arrow Y), and a second folded portion 23 provided at the rear end of the first general portion 21 (direction of arrow Y). In this embodiment, the first folded portion 22 extends by folding downward (opposite direction of arrow Z), but is not limited to this, and may extend rearward (direction of arrow Y) depending on the shape or size of the resin member 2. Similarly, the second folded portion 23 extends by folding downward and forward (opposite direction of arrow Y), but may also extend upward (direction of arrow Z) or rearward.

[0014] The second resin member 30 has a second general portion 31 that faces the first general portion 21 and extends in the first direction X and the second direction Y, a front vertical wall portion 32 that connects to the rear end of the second general portion 31 (direction of arrow Y) and extends downward (opposite direction of arrow Z) and rearward (direction of arrow Y), and a rear vertical wall portion 33 that connects to the rear end of the front vertical wall portion 32 and extends upward (direction of arrow Z) and rearward. The first folded portion 22 is hooked onto the front edge of the second general portion 31 (opposite direction of arrow Y), and the second folded portion 23 is hooked onto the rear edge of the first resin member 20 (direction of arrow Y). As a result, the front vertical wall portion 32 and the rear vertical wall portion 33 form a space 34 between them and the first general portion 21 of the first resin member 20. Electrical components of the vehicle C may be housed in the space 34. The rear vertical wall portion 33 of this embodiment, together with the first resin member 20, forms part of the design of the rear end of the vehicle C.

[0015] The second resin member 30 may further have a joint portion 35. The joint portion 35 is provided on the second general portion 31 and is joined to the first general portion 21 by a double-sided tape. Thereby, the second resin member 30 is joined to the first resin member 20. However, the joining is not limited thereto, and it may be by screws, bolts and nuts, heat welding, an adhesive (hot melt), or other joining means.

[0016] The first resin member 20 and the second resin member 30 may be formed of a thermoplastic resin. Examples of the thermoplastic resin include an ABS resin, polypropylene (PP), polyethylene (PE), an ASA resin (Acrylate Sthrene Acrylonitrile), polystyrene (PS), an acrylic resin, a polycarbonate (PC) resin, a polyamide, a polyethylene terephthalate (PET), and a modified polyphenylene ether (modified-PPE).

[0017] The structure 4 has a third general portion 40 that faces the second general portion 31 and extends in the first direction X and the second direction Y, and a rear wall portion 41 that is connected to the rear end portion (in the direction of arrow Y) of the third general portion 40 and extends downward (in the opposite direction of arrow Z) and rearward (in the direction of arrow Y). The rear wall portion 41 of the present embodiment faces the front vertical wall portion 32 of the second resin member 30. The structure 4 further has a through hole 42. The through hole 42 is provided in the third general portion 40 and penetrates in the third direction Z.

[0018] The sheet metal member 8 is a metal plate-like member that is disposed between the first resin member 20 and the second resin member 30 (that is, inside the spoiler) and is laminated on the second resin member 30 from the opposite side of the structure 4. In the present embodiment, the lamination direction of the structure 4, the second resin member 30, and the sheet metal member 8 generally coincides with the third direction Z. However, it is not limited thereto, and the lamination direction may be shifted in the first direction X or the second direction Y according to the shape or size of the structure 4 and the resin member 2.

[0019] In this embodiment, the fastening member 10 is a metal bolt 11 and a metal nut 12. However, the fastening member 10 is not limited thereto and may be, for example, a clip, a screw, or other fasteners. The bolt 11 has a shaft portion 11a extending along the third direction Z, a flange portion 11b connected to an end of the shaft portion 11a, and a dish portion 11c rotatably attached to the shaft portion 11a. The shaft portion 11a is inserted into the through hole 42 of the structure 4. The flange portion 11b is disposed between the first resin member 20 and the second resin member 30 (inside the spoiler). The dish portion 11c is disposed between the second resin member 30 and the structure 4. The nut 12 is fastened to the shaft portion 11a from the opposite side of the resin member 2 across the structure 4. Thereby, the second resin member 3 and the sheet metal member 8 are sandwiched between the flange portion 11b and the structure 4, and the resin member 2 is fastened and fixed to the structure 4.

[0020] The resin member 2 has an attachment portion 61 for attaching the fastening member 10 and a vertical wall portion 62. The attachment portion 61 and the vertical wall portion 62 are provided on the second resin member 30 and are plate-shaped having substantially the same thickness as the second general portion 31 of the second resin member 30. The attachment portion 61 is disposed spaced downward (opposite direction of the arrow Z) from the second general portion 31 and extends in the first direction X and the second direction Y. The vertical wall portion 62 is a vertical wall connecting between the attachment portion 61 and the second general portion 31.

[0021] FIG. 3 is an exploded perspective view showing an enlargement of the periphery of the attachment portion 61, the sheet metal member 8, and the fastening member 10. As shown in FIG. 3, the flange portion 11b of this embodiment is plate-shaped long in the first direction X.

[0022] The mounting portion 61 includes a first end 61a, a second end 61b facing the first end 61a, a third end 61c connecting the first end 61a and the second end 61b, and a fourth end 61d facing the third end 61c and connecting the first end 61a and the second end 61b. The vertical wall portion 62 includes a first vertical wall 62a connected to the first end 61a, a second vertical wall 62b connected to the second end 61b and facing the first vertical wall 62a, a third vertical wall 62c connected to the third end 61c and connecting the first vertical wall 62a and the second vertical wall 62b, and a fourth vertical wall 62d facing the third vertical wall 62c. As a result, a housing space S surrounded by the mounting portion 61 and the vertical wall portion 62 is formed in the resin member 2.

[0023] The resin member 2 further has a first slit 64 and an insertion hole 65.

[0024] The first slit 64 is provided in the mounting portion 61. The first slit 64 extends in a first direction X from the first end portion 61a of the mounting portion 61. Figure 4(a) is a plan view showing the area around the mounting portion 61 of the resin member 2, and Figure 4(b) is a cross-sectional view corresponding to the BB section in Figure 4(a). As shown in Figure 4(a), the first slit 64 is defined by a first side wall 64a, a second side wall 64b facing the first side wall 64a, and a third side wall 64c connecting the first side wall 64a and the second side wall 64b. In the second direction Y, the first slit 64 has a width d1 (the distance between the first side wall 64a and the second side wall 64b).

[0025] The insertion hole 65 penetrates a portion of the first vertical wall 62a of the vertical wall portion 62 in the first direction X or the third direction Z, and is continuous with the first slit 64. In this embodiment, the insertion hole 65 is defined by the first end portion 61a of the mounting portion 61 and the first vertical wall 62a.

[0026] The resin member 2 further has an opposing portion 66. The opposing portion 66 extends along a first direction X from the upper end (arrow Z direction) of the first vertical wall 62a toward the accommodating space S. In a second direction Y, the opposing portion 66 has a width d2 that is smaller than the width d1 of the first slit 64. The opposing portion 66 includes an opposing surface 66a which is the side facing the mounting portion 61, a base portion 66b which is connected to the first vertical wall 62a, and a tip portion 66c which is the end opposite to the base portion 66b. In this embodiment, the base portion 66b is formed to be wider than the tip portion 66c. In a first direction X, the tip portion 66c is positioned on the side of the first end portion 61a than the third side wall 64c of the first slit 64. As shown in Figure 4(b), in a third direction Z, the opposing portion 66 is positioned opposite the first slit 64. As a result, the opposing portion 66, together with the vertical wall portion 62, forms the accommodating space S between itself and the mounting portion 61. In this embodiment, the accommodation space S is part of the internal space of the base, which is composed of a mounting portion 61 and a vertical wall portion 62 that protrude from the second general portion 31 toward the structure 4.

[0027] The opposing portion 66 further includes a detachment suppression portion 66d. The detachment suppression portion 66d is provided on the opposing surface 66a and is positioned between the base portion 66b and the tip portion 66c in the first direction X. The detachment suppression portion 66d changes the distance between the opposing surface 66a and the mounting portion 61 in the third direction Z. The distance h1 between the opposing surface 66a and the mounting portion 61 at the tip portion 66c is greater than the distance h2 between the opposing surface 66a and the mounting portion 61 at the base portion 66b. In this embodiment, the detachment suppression portion 66d is an inclined surface that slopes away from the mounting portion 61 from the base portion 66b toward the tip portion 66c. However, it is not limited to this, and the detachment suppression portion 66d may be a step, projection, or recess provided on the opposing surface 66a.

[0028] Returning to Figure 3, the structure of the sheet metal member 8 will be described. The sheet metal member 8 has a first plate portion 81 that extends in a first direction X and a second direction Y, a second plate portion 82 that is connected to the first plate portion 81 and extends in a direction intersecting the first plate portion 81, a third plate portion 83 that is connected to the end of the second plate portion 82 on the side opposite to the first plate portion 81 and extends in a first direction X and a second direction Y, a second slit 84, a guide portion 85, and a projection portion 86. In the sheet metal member 8 of this embodiment, the first plate portion 81 and the second plate portion 82 are housed in the housing space S together with the flange portion 11b of the fastening member 10.

[0029] The sheet metal member 8 is laminated onto the second resin member 30 from above (in the direction of arrow Z). Specifically, the first plate portion 81 is laminated onto the mounting portion 61, and the second plate portion 82 is laminated onto the second vertical wall 62b, the third vertical wall 62c, and the fourth vertical wall 62d, respectively. In addition, the third plate portion 83 is laminated onto the second general portion 31 surrounding the mounting portion 61 and the vertical wall portion 62. The first plate portion 81 includes a first end portion 81a that overlaps with the first end portion 61a of the mounting portion 61, a second end portion 81b that overlaps with the second end portion 61b of the mounting portion 61 on the opposite side of the first end portion 81a, a third end portion 81c that connects the first end portion 81a and the second end portion 81b and overlaps with the third end portion 61c of the mounting portion 61, and a fourth end portion 81d that connects the first end portion 81a and the second end portion 81b on the opposite side of the third end portion 81c and overlaps with the fourth end portion 61d of the mounting portion 61.

[0030] The second slit 84 is provided in the first plate portion 81. The second slit 84 extends in a first direction X from the first end portion 81a of the first plate portion 81. Figure 5(a) is a plan view showing the sheet metal member 8, Figure 5(b) is a cross-sectional view corresponding to the CC section of Figure 5(a), and Figure 5(c) is a cross-sectional view corresponding to the DD section of Figure 5(a). As shown in Figure 5(a), the second slit 84 is defined by a first side wall 84a, a second side wall 84b facing the first side wall 84a, and a third side wall 84c connecting the first side wall 84a and the second side wall 84b. In the second direction Y, the second slit 84 has a width d3 (distance between the first side wall 84a and the second side wall 84b) that is greater than the width d1 of the first slit 64 and the width d2 of the opposing portion 66.

[0031] The guide portion 85 is an extension extending from the first end portion 81a in the first direction X (opposite direction of arrow X). The guide portion 85 includes a first guide portion 85a and a second guide portion 85b positioned on the opposite side of the second slit 84 from the first guide portion 85a. As shown in Figure 5(b), the guide portion 85 includes a base portion 851 connected to the first end portion 81a and a tip portion 852 on the opposite side of the base portion 851.

[0032] As shown in Figure 5(c), the projection 86 is positioned on the first plate portion 81 and protrudes upward (in the direction of arrow Z). In this embodiment, the projection 86 is formed by bending the third end portion 81c of the first plate portion 81 and a part of the second plate portion 82 connected to the third end portion 81c. However, the projection 86 may also be positioned on the fourth end portion 81d of the first plate portion 81 and a part of the second plate portion 82 connected to the fourth end portion 81d, or multiple projections may be provided near the second slit 84.

[0033] Next, using Figures 6 and 7, the mounting state in which the sheet metal member 8 is laminated on the mounting portion 61 of the resin member 2 and the fastening member 10 is attached will be described. Figure 6(a) is a perspective view showing an enlarged view of the area around the mounting portion 61 in the mounting state, and Figure 6(b) is a cross-sectional view corresponding to the EE section in Figure 6(a). As shown in Figure 6(a), in the mounting state, a part of the sheet metal member 8 is housed in the accommodation space S formed by the mounting portion 61 and the vertical wall portion 62. The second slit 84 overlaps with the first slit 64 in the third direction Z. As a result, the shaft portion 11a of the fastening member 10 can be inserted into the first slit 64 and the second slit 84. Furthermore, the guide portion 85 protrudes in the first direction X (opposite direction of arrow X) from the first end portion 61a of the mounting portion 61.

[0034] As shown in Figure 6(b), the shaft portion 11a of the fastening member 10 is positioned within the first slit 64 and the second slit 84 in the installed state, and penetrates both the first slit 64 and the second slit 84. The flange portion 11b is positioned within the housing space S. The dish portion 11c is positioned below the mounting portion 61 (in the opposite direction of arrow Z).

[0035] The first plate portion 81 of the sheet metal member 8 is positioned between the mounting portion 61 and the opposing surface 66a of the opposing portion 66 in the third direction Z. Furthermore, the flange portion 11b of the fastening member 10 is positioned between the first plate portion 81 of the sheet metal member 8 and the opposing surface 66a of the opposing portion 66. As a result, the flange portion 11b and the dish portion 11c sandwich the mounting portion 61 and the first plate portion 81 of the sheet metal member 8 in the third direction Z, thereby holding the fastening member 10 to the mounting portion 61 on which the sheet metal members 8 are stacked.

[0036] Next, the method of attaching the fastening member 10 and the effects of the guide portion 85, the detachment suppression portion 66d, and the projection portion 86 will be described. The fastening member 10 is inserted into the mounting portion 61 along the first direction X from the pre-attachment position shown by the dashed line in Figure 6(b), and is attached at the attachment position shown by the solid line. The fastening member 10 is attached to the mounting portion 61, which is made up of laminated sheet metal members 8, from the first end portion 61a side. In this embodiment, the flange portion 11b of the fastening member 10 is inserted between the guide portion 85 and the opposing portion 66 via the insertion hole 65 and is inserted into the housing space S.

[0037] The resin member 2 can be reinforced by laminating the sheet metal member 8 onto the mounting portion 61. The resin member 2 may be subjected to loads due to external impacts, etc. Compared to the resin second resin member 30, the metal sheet metal member 8, which has higher rigidity, can maintain its shape without deformation in response to such loads, thereby suppressing deformation of the housing space S and, consequently, the mounting portion 61 and the area around the vertical wall portion 62. As a result, the sheet metal member 8 can reinforce the resin member 2 by improving the rigidity of the second resin member 30.

[0038] On the other hand, when the sheet metal member 8 is laminated on the mounting portion 61, the ease of assembly of the fastening member 10 may decrease when attaching the fastening member 10 to the mounting portion 61 on which the sheet metal member 8 is laminated. As shown in Figure 6(b), the distance h3 between the opposing surface 66a at the base portion 851 and the sheet metal member 8 is smaller than the distance h4 between the opposing surface 66a at the tip portion 852 and the sheet metal member 8. Here, the distance h4 is set to be approximately the same as the thickness of the flange portion 11b of the fastening member 10. Therefore, in order to insert the flange portion 11b of the fastening member 10 into the housing space S, it is necessary to deform at least one of the base portion 851 and the sheet metal member 8 to widen the distance between the opposing surface 66a at the base portion 851 and the sheet metal member 8. However, since the sheet metal member 8 is made of metal and is difficult to deform, the base portion 851 must be deformed more significantly than when there is no sheet metal member 8. If the base portion 851 does not deform sufficiently, it becomes difficult to insert the flange portion 11b of the fastening member 10 into the housing space S, and the ease of assembly of the fastening member 10 decreases.

[0039] In this embodiment, the sheet metal member 8 is provided with a guide portion 85 that guides the flange portion 11b toward the housing space S. The guide portion 85 has a shape in which the distance between the guide portion 85 and the opposing surface 66a is maximum at the tip portion 852, decreases along the first direction X (direction of arrow X), and minimum at the base portion 851. The guide portion 85 in this embodiment is an inclined surface that slopes away from the opposing portion 66 as it moves away from the first end portion 61a in the first direction X, that is, it slopes downward (opposite direction of arrow Z) along the first direction X (direction of arrow X). However, the guide portion 85 is not limited to this and may be a step, projection, or convex portion.

[0040] When the fastening member 10 is installed, the flange portion 11b is positioned between the guide portion 85 and the opposing surface 66a at the tip portion 852 of the guide portion 85, and moves along the inclination of the guide portion 85, thereby deforming the base portion 851 while being supported in its position by the guide portion 85. Therefore, the assembly worker installing the fastening member 10 to the mounting portion 61 can move it to the housing space S and position the fastening member 10 in the mounting position more easily than in the case where the base portion 851 is deformed without support, as would be the case if the guide portion 85 were absent. In this way, the guide portion 85 can guide the flange portion 11b toward the housing space S. As the flange portion 11b is inserted, the shaft portion 11a moves along the first direction X within the first slit 64 and the second slit 84, and the disc portion 11c moves to the mounting position on the mounting portion 61, sandwiching the sheet metal member 8 and the mounting portion 61 together with the flange portion 11b.

[0041] As the flange portion 11b moves to the mounting position, it overcomes the detachment restraint portion 66d provided on the opposing surface 66a. When the flange portion 11b moves along the first direction X, it is moving in a direction that increases the distance between the opposing surface 66a and the mounting portion 61, so the flange portion 11b can easily overcome the detachment restraint portion 66d. Therefore, the assembly worker can easily insert the flange portion 11b to the mounting position beyond the detachment restraint portion 66d.

[0042] On the other hand, movement of the flange portion 11b and, consequently, the fastening member 10, in the direction opposite to the first direction X from the mounting position, that is, in the direction in which the fastening member 10 detaches from the mounting portion 61, is in a direction in which the distance between the opposing surface 66a and the mounting portion 61 decreases. Therefore, the detachment suppression portion 66d can suppress the flange portion 11b from riding over it, and can suppress the movement of the flange portion 11b to its pre-mounting position, that is, the detachment of the flange portion 11b from the housing space S. As a result, the detachment suppression portion 66d can prevent the fastening member 10 in the mounted state from falling off the mounting portion 61 and, consequently, the resin member 2.

[0043] In this embodiment, the detachment suppression portion 66d is positioned spaced apart from the guide portion 85 in the first direction X. As a result, the opposing portion 66 and the sheet metal member 8 can form a section t between the guide portion 85 and the detachment suppression portion 66d, where the distance between the opposing surface 66a and the sheet metal member 8 in the third direction Z is narrowed. Therefore, when the flange portion 11b at the mounting position attempts to move in the first direction X (opposite direction to arrow X), the flange portion 11b is prevented from detaching from the housing space S by the detachment suppression portion 66d, and even if it manages to overcome the detachment suppression portion 66d, it is trapped between the first plate portion 81 and the opposing surface 66a in section t, hindering its movement. As a result, the opposing portion 66 and the sheet metal member 8 can prevent the flange portion 11b from detaching from its mounting position and, consequently, the fastening member 10 from falling off the resin member 2.

[0044] Figure 7(a) is a plan view showing the area around the mounting portion 61 in the installed state, and Figure 7(b) is a cross-sectional view corresponding to the FF cross section in Figure 7(a). As shown in Figure 7(a), the fastening member 10 has an elliptical or rounded rectangular flange portion 11b, which is inserted into the housing space S with its longitudinal direction aligned with the first direction X. As shown in Figure 7(b), in the installed state, the long side 110 of the flange portion 11b is positioned adjacent to the projection 86. This allows the projection 86 to inhibit the rotational movement of the flange portion 11b around the shaft portion 11a. As a result, the projection 86 can prevent the fastening member 10 from rotating in the installed position.

[0045] <Second Embodiment> Next, a second embodiment of the present disclosure will be described with reference to Figure 8. Note that the following description will describe a configuration different from the first embodiment, and redundant explanations will be omitted. As shown in Figure 8, the mounting portion 61 of this embodiment is provided flush with the second general portion 31 of the second resin member 30. Furthermore, the opposing portion 66 is spaced apart from the mounting portion 61 and the second general portion 31 upward (in the direction of arrow Z). The resin member 2 has a vertical wall portion 68 that connects the opposing portion 66 and the second general portion 31. The vertical wall portion 68 extends in the second direction Y and the third direction Z, and together with the mounting portion 61 and the opposing portion 66, forms a housing space S. In this embodiment, the fastening member 10 has its flange portion 11b inserted diagonally between the vertical wall portion 68 and the guide portion 85, as shown by the dashed line in Figure 8. At this time, the flange portion 11b is guided by the guide portion 85, which deforms the vertical wall portion 68 and the base portion 851 while supporting the orientation of the flange portion 11b. This allows the person assembling the fastening member 10 to easily move the fastening member 10 to the mounting position.

[0046] As described above, the fastening structure 1 according to this embodiment can achieve the following effects.

[0047] The fastening structure 1 is a fastening structure 1 for a resin member 2 fastened to a structure 4 by a fastening member 10, comprising the resin member 2 and a sheet metal member 8, wherein the resin member 2 has a mounting portion 61 that extends in a first direction X and a second direction Y intersecting the first direction X, to which the fastening member 10 is attached, a first slit 64 provided in the mounting portion 61 and extending in the first direction X from the first end 61a of the mounting portion 61, and a facing portion 66 that is positioned opposite the first slit 64 in a third direction Z intersecting the first direction X and the second direction Y The sheet metal member 8 is laminated onto the mounting portion 61 from the opposite side of the structure 4, and the fastening member 10 is attached to the mounting portion 61 from the first end 61a, and with the fastening member 10 attached to the mounting portion 61, the shaft portion 11a passes through the first slit 64, and the flange portion 11b connected to the shaft portion 11a is housed in the housing space S between the sheet metal member 8 and the opposing portion 66, and the sheet metal member 8 has a guide portion 85 that protrudes beyond the first end 61a in the first direction X and guides the flange portion 11b toward the housing space S.

[0048] With this fastening structure 1, the sheet metal member 8 can maintain its shape without deformation when subjected to external load input, thereby suppressing deformation of the housing space S and the surrounding area of ​​the mounting portion 61 and vertical wall portion 62, and reinforcing the resin member 2 by improving the rigidity of the second resin member 30. Furthermore, the guide portion 85 of the sheet metal member 8 can guide the flange portion 11b of the fastening member 10 between the opposing portion 66 and the sheet metal member 8, before it reaches the first end portion 61a of the mounting portion 61. As a result, the assembly worker can easily insert the flange portion 11b into the housing space S, improving assembly workability.

[0049] Furthermore, the sheet metal member 8 may have a second slit 84 that overlaps with the first slit 64 in the third direction Z, and the guide portion 85 may include a first guide portion 85a and a second guide portion 85b that is positioned on the opposite side of the first guide portion 85a, with the second slit 84 in between.

[0050] As a result, the guide portion 85 can guide the flange portion 11b between the opposing portion 66 and the sheet metal member 8 at two locations in the second direction Y, sandwiching the first slit 64 and the second slit 84.

[0051] Furthermore, the guide portion 85 may be an inclined surface that slopes away from the opposing portion 66 as it moves away from the first end portion 61a in the first direction X.

[0052] As a result, the guide unit 85 can guide the flange portion 11b into the housing space S while gradually narrowing the distance between the opposing surface 66a and the sheet metal member 8 in the third direction Z.

[0053] Furthermore, the width d2 of the opposing portion 66 in the second direction Y may be smaller than the width d3 of the second slit 84 in the second direction.

[0054] As a result, the opposing portion 66 becomes more easily deformed compared to when its width d2 is greater than or equal to its width d3. Therefore, assembly is improved when guiding the flange portion 11b between the opposing portion 66 and the sheet metal member 8.

[0055] Furthermore, the opposing portion 66 is provided on the opposing surface 66a, which is the surface on the mounting portion 61 side, and includes a detachment suppression portion 66d that suppresses the detachment of the flange portion 11b from the housing space S, and the detachment suppression portion 66d may be spaced apart from the guide portion 85 in the first direction X.

[0056] As a result, the opposing portion 66 and the sheet metal member 8 can form a section t between the guiding portion 85 and the detachment suppression portion 66d, narrowing the distance between the opposing surface 66a and the sheet metal member 8 in the third direction Z. Therefore, if the flange portion 11b at the mounting position attempts to move to the opposite side of the first direction X, even if the flange portion 11b goes over the detachment suppression portion 66d, it will be trapped between the first plate portion 81 and the opposing surface 66a in section t, hindering its movement. Consequently, the opposing portion 66 and the sheet metal member 8 can prevent the flange portion 11b from detaching from its mounting position and, consequently, the fastening member 10 from falling off the resin member 2.

[0057] Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. In particular, the various modifications described herein can be combined as needed.

[0058] In the above embodiment, a spoiler is given as an example of a resin component. The technology of this disclosure is not limited to this and can be applied to any resin component that requires high rigidity in terms of dimensions or shape. [Explanation of symbols]
