[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0009] As shown in Fig. 1, in this embodiment, the resin member 2 is a spoiler attached to a vehicle C, and the structural body 4 is a roof panel of the vehicle C. In Fig. 1, the arrow W corresponds to the width direction of the vehicle C, the arrow L corresponds to the front-rear direction of the vehicle C, and the arrow H corresponds to the up-down direction of the vehicle C. The resin member 2 is not limited to the vehicle C, and may be a member attached to a framework or panel that forms an aircraft, ship, building, or other structure.

[0010] The resin member 2 includes a first resin member 21 disposed on the structural body 4 side and a second resin member 31 disposed opposite the first resin member 21. In this embodiment, the first resin member 21 is an inner panel of the spoiler. The second resin member 31 is an outer panel of the spoiler and forms the design surface of the vehicle C.

[0011] The first resin member 21 includes a plate-shaped first plate-shaped portion 22 extending in the vehicle width direction W and the fore-and-aft direction L of the vehicle C, a protruding portion 23 protruding downward from the first plate-shaped portion 22 (in the opposite direction to the arrow H in Figure 1), and an internal connecting portion 25 connected to the second resin member 31.

[0012] The protruding portion 23 has a tip surface 23a that is the tip surface on the protruding side, a front vertical wall 23b that connects the first plate-shaped portion 22 and the tip surface 23a, and a rear vertical wall 23c that is connected to the tip surface 23a and faces the front vertical wall 23b. The protruding portion 23 forms an accommodation space 23d that is defined by the tip surface 23a, the front vertical wall 23b, and the rear vertical wall 23c. The accommodation space 23d can accommodate electrical components such as brake lights of the vehicle C, an imaging device, or various sensors, for example.

[0013] The internal connecting portion 25 is provided on the first plate-shaped portion 22 and joined to the second resin member 31 by thermal welding. However, joining is not limited to this, and joining may also be by screws, bolts and nuts, adhesive, double-sided tape, or other joining means.

[0014] The second resin member 31 includes a plate-like second plate-shaped portion 32 that faces the first plate-shaped portion 22 and extends in the vehicle width direction W and the front-rear direction L of the vehicle C, and a folded-back portion 33 that is folded back from the second plate-shaped portion 32. The second plate-shaped portion 32 is in contact with the first plate-shaped portion 22 or faces the first plate-shaped portion 22 with a small gap between them. The folded-back portion 33 is hooked onto the rear vertical wall 23c of the first resin member 21. This causes the second resin member 31 to be locked to the first resin member 21.

[0015] The first resin member 21 and the second resin member 31 may be made of a thermoplastic resin. The thermoplastic resin is, for example, polypropylene (PP). However, the thermoplastic resin is not limited to this, and may be selected from ABS resin, polyethylene (PE), polystyrene (PS), acrylic resin, polycarbonate (PC) resin, polyamide, polyethylene terephthalate (PET), and modified polyphenylene ether (modified PPE).

[0016] The fastening structure 1 for fastening the resin member 2 to the structure 4 includes a base 6 provided on the resin member 2 and a fastening member 10 held by the base 6. The base 6 is provided on a first plate-shaped portion 22 of a first resin member 21 and protrudes toward the structure 4. The fastening member 10 is a bolt 11 and a nut 12, but is not limited to this. The fastening member 10 may be, for example, a clip, a screw, or other fastener. In this embodiment, the bolt 11 held by the base 6 is inserted into a bolt hole 40 in the structure 4. Furthermore, the bolt 11 is fastened with a nut 12 arranged on the opposite side of the resin member 2 across the structure 4. In this way, the resin member 2 is fastened to the structure 4 by the fastening member 10.

[0017] Fig. 2 is a plan view of the first resin member 21 as viewed from the second resin member 31 side. Line AA in Fig. 2 corresponds to the cross section of Fig. 1. As shown in Fig. 2, in this embodiment, the pedestal 6 includes a first pedestal 6a, a second pedestal 6b, a third pedestal 6c, a fourth pedestal 6d, a fifth pedestal 6e, and a sixth pedestal 6f.

[0018] The first seat 6a and the second seat 6b are disposed near the center of the first resin member 21 in the first direction X. The third seat 6c and the fourth seat 6d are disposed outward of the first seat 6a and the second seat 6b in the first direction X. The fifth seat 6e and the sixth seat 6f are disposed at positions different from the first seat 6a to the fourth seat 6d in the second direction Y.

[0019] Fig. 3(a) is an enlarged plan view of portion B in Fig. 2, and Fig. 3(b) is a cross-sectional view showing cross section CC of Fig. 3(a). The base 6 has a base plate 61 spaced apart from the first plate-shaped portion 22 in the third direction Z, and legs 62 connecting the base plate 61 and the first plate-shaped portion 22. In this embodiment, the base plate 61 and the legs 62 are plate-shaped and have approximately the same thickness as the first plate-shaped portion 22.

[0020] The base plate 61 extends in the first direction X and the second direction Y. In this embodiment, the base plate 61 has a rectangular shape including a first end 61a, a second end 61b, a third end 61c, and a fourth end 61d, and the first end 61a is connected to the front vertical wall 23b of the protrusion 23 without via the leg portions 62. The leg portions 62 extend from the second end 61b, the third end 61c, and the fourth end 61d and connect to the first plate-shaped portion 22. A space S surrounded by the base plate 61 and the leg portions 62 is formed in the first resin member 21.

[0021] The base plate 61 further has a guide hole 66 into which the fastening member 10 is inserted, an opening 67 that receives the fastening member 10, and a claw hole 68. The opening 67 is continuous with the guide hole 66.

[0022] The guide hole 66 is a slit provided in the base plate 61 and extending in the first direction X. In this embodiment, the guide hole 66 is defined by a first side wall 66a extending in the first direction X, a second side wall 66b facing the first side wall 66a, and a connecting wall 66c connecting the first side wall 66a and the second side wall 66b.

[0023] 3(b), the opening 67 is provided in the leg portion 62 extending from the fourth end portion 61d and penetrates in the first direction X. As shown in FIGS. 3(a) and 3(b), the opening 67 in this embodiment is defined by a third side wall 67a connected to the first side wall 66a, a fourth side wall 67b connected to the second side wall 66b, and an end wall 67c extending in the second direction Y.

[0024] 3(a) and 3(b), the nail hole 68 is provided in the base plate 61 so as to be spaced from the guide hole 66 in the second direction Y and penetrates in the third direction Z. In this embodiment, the nail hole 68 is provided adjacent to the second side wall 66b of the guide hole 66, but is not limited to this and may be provided adjacent to the first side wall 66a of the guide hole 66. The nail hole 68 includes a first hole portion 68a extending in the first direction X and a second hole portion 68b connected to the first hole portion 68a and extending toward the guide hole 66. In this embodiment, the nail hole 68 is L-shaped including the first hole portion 68a and the second hole portion 68b that are perpendicular to each other, but is not limited to this and the angle formed by the first hole portion 68a and the second hole portion 68b of the nail hole 68 can be changed.

[0025] The first hole portion 68a has a first end portion 681 disposed on the connecting wall 66c side of the guide hole 66, and a second end portion 682 connected to the second hole portion 68b on the opposite side to the first end portion 681, i.e., on the front (opening 67) side of the guide hole 66. The first hole portion 68a is disposed at a first distance D1 from the second side wall 66b of the guide hole 66 in the second direction Y.

[0026] The second hole portion 68b has a third end portion 683 connected to the first hole portion 68a, a fourth end portion 684 disposed on the opposite side of the third end portion 683, and a fifth end portion 685 connecting the third end portion 683 and the fourth end portion 684. The fourth end portion 684 is disposed in the second direction Y at a second distance D2 that is smaller than the first distance D1 from the second side wall 66b of the guide hole 66. The fifth end portion 685 is disposed in the first direction X at a third distance D3 that is smaller than the first distance D1 from the fourth side wall 67b of the opening 67. In this embodiment, the second distance D2 and the third distance D3 are greater than or equal to one-third and less than one-half of the first distance D1, but the magnitudes of the first distance D1, the second distance D2, and the third distance D3 can be changed. In this embodiment, the second distance D2 and the third distance D3 are each designed to be 5 mm or more, thereby ensuring the strength of the base 6.

[0027] Next, a description will be given of the fastening member 10 held by the base 6. The fastening member 10 is made of a metal having greater rigidity than the resin member 2. The material of the fastening member 10 is, for example, iron, stainless steel, titanium, or other metallic materials.

[0028] Fig. 4 is a three-view diagram showing a fastening member 10 (bolt 11), in which Fig. 4(a) is a plan view of the fastening member 10, Fig. 4(b) is a right side view of the fastening member 10, and Fig. 4(c) is a front view of the fastening member 10. As shown in Figs. 4(a) to 4(c), the fastening member 10 has a shaft 10a, a first flange 10b connected to the shaft 10a, a second flange 10c facing the first flange 10b and connected to the shaft 10a, an arm portion 10d connected to the first flange 10b, and a claw portion 10e connected to the arm portion 10d.

[0029] As shown in FIG. 4(a), the first flange 10b is plate-shaped and extends in a direction intersecting the central axis O of the shaft 10a. The first flange 10b includes a first surface S1 facing the second flange 10c (see FIGS. 4(b) and 4(c)). The first flange 10b of this embodiment is perpendicular to the central axis O of the shaft 10a and includes a first edge 101, a second edge 102 opposed to the first edge 101, a third edge 103 connecting the first edge 101 and the second edge 102, and a fourth edge 104 opposed to the third edge 103 and connecting the first edge 101 and the second edge 102. The first edge 101 and the second edge 102 of this embodiment are arcs that are part of a circle centered on the central axis O. The third edge 103 and the fourth edge 104 are each linear. However, the shape of the first edge portion 101 to the fourth edge portion 104, and therefore the first flange 10b, is not limited to this, and may be selected from a circular, rectangular, or other shapes.

[0030] The second flange 10c is plate-shaped and extends in a direction intersecting the central axis O of the shaft 10a and parallel to the first flange 10b. The second flange 10c includes a second surface S2 facing the first flange 10b (see FIGS. 4(b) and 4(c)). In this embodiment, the second flange 10c is orthogonal to the central axis O of the shaft 10a and has a circular shape centered on the central axis O. However, the second flange 10c is not limited to this, and may have a shape combining arcs and straight lines, as with the first flange 10b, or a rectangular shape.

[0031] The arm portion 10d is plate-shaped and extends from a connection point between the first edge portion 101 and the third edge portion 103 of the first flange 10b. The arm portion 10d is disposed at a first distance C1 from the central axis O and extends at a second distance C2 from an end portion of the first flange 10b (the third edge portion 103 in this embodiment). When the fastening member 10 is fastened to the base 6 (see FIG. 3(a)), the arm portion 10d is connected to the first flange 10b at a position spaced from the axis 10a of the fastening member 10 toward the back side of the guide hole 66 in the first direction X, and extends in the second direction Y (a direction different from the first direction X) (see FIG. 5(a) described below).

[0032] As described above, in order to ensure the strength of the base 6, the second distance D2 (the distance between the second hole portion 68b and the guide hole 66) and the third distance D3 (the distance between the second hole portion 68b and the opening 67) of the base 6 are each designed to be 5 mm or more. If the arm member 10d is directly connected to the shaft 10a of the fastening member 10 based on this design, the portion of the base 6 where the second side wall 66b of the guide hole 66 and the fourth side wall 67b of the opening 67 are connected and its surrounding area (hereinafter simply referred to as the "connection portion") can be cut to allow the fastening member 10 to be rotated on a plane and smoothly moved into the guide hole 66 when attaching the fastening member 10 to the base 6, as will be described later. In this case, in order to design the second distance D2 and the third distance D3 of the base 6 to be 5 mm or more when the connection portion has been cut, the base 6 needs to be made sufficiently larger than its existing size. However, due to the structure of the resin member 2 (spoiler), there is a limit to the size of the base 6, so it is not practical to cut down the connection portion. Therefore, in this embodiment, the arm portion 10d is connected to a position spaced from the shaft 10a toward the back side of the guide hole 66 in the first direction X, and is configured to extend in the second direction Y. This ensures the strength of the base 6 and allows the base 6 to maintain its existing size, and when attaching the fastening member 10 to the base 6, the fastening member 10 can be rotated on a plane and moved smoothly into the guide hole 66.

[0033] 4(b) and (c), the claw portion 10e protrudes parallel to the central axis O from an end portion 105 of the arm portion 10d opposite the first flange 10b. A tip surface 106 of the claw portion 10e is disposed between the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c in the direction along the central axis O. That is, a third distance C3, which is the amount of protrusion of the claw portion 10e from the arm portion 10d (the distance between the first surface S1 and the tip surface 106), is smaller than a fourth distance C4 between the first surface S1 and the second surface S2.

[0034] Next, a state in which the fastening member 10 is held by the pedestal 6 (hereinafter referred to as the held state) will be described with reference to Fig. 5. Fig. 5(a) is a plan view showing the held state using the first pedestal 6a as an example, and Fig. 5(b) corresponds to the DD cross section of Fig. 5(a). As shown in Fig. 5, in the held state, the fastening member 10 is located near the connecting wall 66c of the guide hole 66.

[0035] 5(a), the shaft 10a is inserted into the guide hole 66. The shaft 10a, and therefore the central axis O of the fastening member 10, is disposed inside the guide hole 66 along the third direction Z. As a result, the base 6 restricts the movement of the shaft 10a, and therefore the fastening member 10, in the first direction X and the second direction Y.

[0036] As shown in FIG. 5(b), the first flange 10b is located inside the space S on the opposite side of the structure 4 (see FIG. 1) in the third direction Z, with the base plate 61 of the base 6 sandwiched between them. The second flange 10c is located on the structure 4 side, facing the first flange 10b in the third direction Z, with the base plate 61 of the base 6 sandwiched between them. In other words, the first flange 10b and the second flange 10c sandwich the base plate 61 between them in the third direction Z. As a result, the first flange 10b and the second flange 10c restrict movement of the fastening member 10 relative to the base 6 in the third direction Z.

[0037] Returning to Fig. 5(a), the arm portion 10d is located closer to the back (connecting wall 66c) of the guide hole 66 in the first direction X than the central axis O of the shaft 10a. Also, as shown in Fig. 5(b), the arm portion 10d, like the first flange 10b, is located inside the space S on the opposite side of the structure 4 in the third direction Z, with the base plate 61 of the base 6 in between.

[0038] The claw portion 10e is inserted into the claw hole 68. As shown in FIG. 5(b), the tip surface 106 of the claw portion 10e is disposed within the first hole portion 68a. As a result, the arm portion 10d, and therefore the fastening member 10, are locked into the claw hole 68 via the claw portion 10e. In this embodiment, the claw portion 10e is located at a first end 681 of the first hole portion 68a (see FIG. 5(a) for both).

[0039] As described above, in this embodiment, the fastening member 10 is inserted into the guide hole 66, and the entire resin member 2 is fastened to the structure 4 via the fastening member 10 (see FIG. 1 for both). The base 6 having such a guide hole 66 may receive an unintended load in a direction in which the resin member 2 is peeled off from the structure 4 due to, for example, an object colliding with the resin member 2. The resin member 2 attempts to move in response to the input load, while the fastening member 10 is fixed to the structure 4. For this reason, the base plate 61 receives a load in the third direction Z via the fastening member 10, centered on the guide hole 66 into which the shaft 10a of the fastening member 10 is inserted, and attempts to deform, starting from the guide hole 66, so that the base plate 61 twists and the guide hole 66 expands.

[0040] In this embodiment, in the held state, the shaft 10a inserted into the guide hole 66 and the claw portion 10e inserted into the claw hole 68 are connected by the arm portion 10d. Furthermore, the arm portion 10d of the fastening member 10 sandwiches the base plate 61 of the base 6 between the structure 4 and the arm portion 10d in the third direction Z. Therefore, when the base plate 61 attempts to move and deform in a direction away from the structure 4 due to an unintended load, the arm portion 10d presses the base plate 61 to stop the movement of the base plate 61, thereby suppressing deformation of the base plate 61 and expansion of the guide hole 66. This makes it possible to prevent the first flange 10b and therefore the fastening member 10 from detaching from the base 6, and as a result, to prevent the resin member 2 from detaching from the structure 4.

[0041] Furthermore, when no unintended load is applied, the arm portion 10d may be in contact with the base plate 61 or may be out of contact. In this embodiment, the arm portion 10d is in contact with the base plate 61. Furthermore, the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c are both in contact with the base plate 61. A fourth distance C4 between the first surface S1 and the second surface S2 is equal to or slightly greater than the thickness of the base plate 61 in the third direction Z. This allows the arm portion 10d to reduce the distance that the base plate 61 can move in the third direction Z, thereby further suppressing deformation of the base plate 61.

[0042] Furthermore, the arm portion 10d, together with the first flange 10b, contacts the base plate 61 from the side of the space S. This allows the arm portion 10d to suppress deformation of the base plate 61 in the third direction Z between the guide hole 66 and the claw hole 68. As a result, the arm portion 10d and the claw portion 10e can suppress deformation of the base plate 61 originating from the guide hole 66, preventing the fastening member 10 from falling off due to deformation of the base plate 61 and ultimately preventing the resin member 2 from falling off the structure 4.

[0043] In this embodiment, as shown in FIG. 1 , the resin member 2 is a spoiler. When an object collides with the resin member 2, the resin member 2 may bend upward due to an upward load applied to the protruding portion 23. In this embodiment, the arm portion 10d extends from the first flange 10b toward the rear of the vehicle, and the claw portion 10e extends from the arm portion 10d toward the bottom of the vehicle. When the resin member 2 bends upward, the portion of the base plate 61 on the rear side of the vehicle receives an upward load. The arm portion 10d presses down on the portion of the base plate 61 on the rear side of the vehicle, and the claw portion 10e bites into the portion of the base plate 61 on the rear side of the vehicle, preventing the portion of the base plate 61 on the rear side of the vehicle from moving upward and preventing the portion of the base plate 61 on the rear side of the vehicle from coming off between the first flange 10b and the second flange 10c.

[0044] Next, a method for attaching the fastening member 10 to the base 6 will be described with reference to FIGS.

[0045] FIG. 6 shows the positional relationship between the base 6 and the fastening member 10 at the initial position P1. FIG. 6(a) is an enlarged plan view of the periphery of the base 6, using the first base 6a as an example, and FIG. 6(b) corresponds to an E-E cross section of FIG. 6(a). As shown in FIG. 6(a), the fastening member 10 is disposed with the arm portion 10d and the claw portion 10e facing the opening 67. The arm portion 10d is disposed at a first angle θ1 with respect to the second direction Y. The claw portion 10e is disposed adjacent to the fourth end 684 of the second hole portion 68b of the claw hole 68 in the second direction Y. As shown in FIG. 6(b), the first flange 10b, arm portion 10d, and claw portion 10e of the fastening member 10 are disposed between the end wall 67c of the opening 67 and the base plate 61 in the third direction Z.

[0046] Next, the fastening member 10 is translated in the first direction X from the initial position P1 indicated by the dashed line in FIG. 7(a) to a second position P2. Note that FIGS. 7(b) and 7(c) correspond to the cross section FF of FIG. 7(a). As shown in FIG. 7(a), the claw portion 10e of the fastening member 10 overlaps with the fourth end 684 of the second hole portion 68b of the base 6 in the third direction Z. At this time, the second flange 10c of the fastening member 10 is not in contact with either the second side wall 66b of the guide hole 66 or the fourth side wall 67b of the opening 67. As shown in FIG. 7(b), the first flange 10b, arm portion 10d, and claw portion 10e of the fastening member 10 pass through the opening 67 and are positioned inside the space S.

[0047] 7(c), the fastening member 10 is translated along the third direction Z and placed at a third position P3. As a result, the claw portions 10e of the fastening member 10 are inserted into the second hole portions 68b of the claw holes 68. At the third position P3, the claw portions 10e of the fastening member 10 are placed inside the second hole portions 68b of the claw holes 68 of the base 6. In addition, the base plate 61 of the base 6 is positioned between the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c in the third direction Z.

[0048] Next, the fastening member 10 is translated in the second direction Y from the third position P3 indicated by the dashed line in Figure 8(a) to the fourth position P4. At this time, the claw portion 10e of the fastening member 10 is moved inside the second hole portion 68b from the fourth end 684 to the third end 683.

[0049] Furthermore, the fastening member 10 is rotated on a plane extending in the first direction X and the second direction Y from a fourth position P4 indicated by a dashed line in FIG. 8(b) to a fifth position P5. The fastening member 10 is rotated around the claw portion 10e by a second angle θ2, which is equal to the first angle θ1 (see FIG. 6(a)), and is smoothly moved into the guide hole 66. At this time, the second flange 10c is moved from the fourth side wall 67b of the opening 67 along the second side wall 66b of the guide hole 66, and the shaft 10a is moved to the inside of the guide hole 66 (between the first side wall 66a and the second side wall 66b in the second direction Y). At the fifth position P5, the shaft 10a is located near the center of the guide hole 66 in the second direction Y, and the arm portion 10d is aligned with the second direction Y. When the fastening member 10 moves from the fourth position P4 to the fifth position P5, the fourth side wall 67b of the opening 67 of the base 6 does not interfere with the second flange 10c of the fastening member 10.

[0050] Finally, the fastening member 10 is translated in the first direction X from the fifth position P5 indicated by the dashed line in Figure 8(c) to be placed at the fastening position P6. At this time, the claw portion 10e of the fastening member 10 is moved inside the first hole portion 68a from the second end 682 (the third end 683 of the second hole portion 68b) to the first end 681. As a result, the fastening member 10 is inserted into the guide hole 66 of the base 6 and is held by the base 6.

[0051] In the present embodiment, an example has been described in which the fastening member 10 is moved in a translational and rotational manner when being moved from the third position P3 to the fifth position P5, but the present disclosure is not limited to this. That is, the fastening member 10 may be moved in a translational and rotational manner simultaneously, from the third position P3 to the fifth position P5 without passing through the fourth position P4.

[0052] As described above, the resin member 2 according to this embodiment can provide the following effects.

[0053] A fastening structure 1 for fastening a resin member 2 to a structure 4, a base 6 provided on the resin member 2; a fastening member 10 held by the base 6; Equipped with The base 6 is a base plate 61 extending in a first direction X and a second direction Y intersecting the first direction X; a guide hole 66 provided in the base plate 61 along the first direction X; a claw hole 68 provided in the base plate 61 so as to be spaced apart from the guide hole 66 in the second direction Y, The fastening member 10 is made of metal, A shaft 10a inserted into the guide hole 66; a first flange 10b connected to the shaft 10a and positioned on the opposite side of the structure 4 across the base plate 61; an arm portion 10d connected to the first flange 10b and positioned on the opposite side of the structure 4 across the base plate 61; a claw portion 10e connected to the arm portion 10d and inserted into the claw hole 68; Fastening structure 1.

[0054] As a result, the shaft 10a inserted into the guide hole 66 and the claw portion 10e inserted into the claw hole 68 are connected by the arm portion 10d. Furthermore, the arm portion 10d of the fastening member 10 sandwiches the base plate 61 of the base 6 between the structure 4 and the arm portion 10d in the third direction Z. Therefore, when the base plate 61 attempts to move and deform in a direction away from the structure 4 due to an unintended load, the arm portion 10d presses the base plate 61 to stop the movement of the base plate 61, thereby suppressing deformation of the base plate 61 and expansion of the guide hole 66. This makes it possible to prevent the first flange 10b and therefore the fastening member 10 from detaching from the base 6, and as a result, to prevent the resin member 2 from detaching from the structure 4.

[0055] The arm portion 10d is connected to the first flange 10b at a position spaced from the axis 10a of the fastening member 10 toward the rear side of the guide hole 66 in the first direction X, and extends in a direction different from the first direction X.

[0056] This ensures the strength of the base 6 and allows the base 6 to be of its existing size, while allowing the fastening member 10 to be rotated on a plane and smoothly moved into the guide hole 66 when attaching the fastening member 10 to the base 6.

[0057] The nail hole 68 includes a first hole portion 68a extending in the first direction X, and a second hole portion 68b connected to the first hole portion 68a and extending from the front end (second end 682) of the first hole portion 68a toward the guide hole 66.

[0058] This allows the fastening member 10 to move on a plane extending in the first direction X and the second direction Y while the claw portion 10e remains positioned inside the claw hole 68. This allows the fastening member 10 to be quickly inserted from the opening 67 into the guide hole 66, improving workability.

[0059] The fastening member 10 further includes a second flange 10c facing the first flange 10b across the base plate 61, The first flange 10b has a first surface S1 facing the second flange 10c, The second flange 10c has a second surface S2 facing the first flange 10b, A tip surface 106 of the claw portion 10e is disposed between the first surface S1 and the second surface S2 in a third direction Z that intersects with the first direction X and the second direction Y.

[0060] As a result, the arm portion 10d and therefore the fastening member 10 are locked in the claw hole 68 via the claw portion 10e. As a result, movement of the fastening member 10 in the second direction Y is restricted at two locations: the shaft 10a located in the guide hole 66 and the claw portion 10e located in the claw hole 68.

[0061] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments, and various modifications are possible within the scope of the gist of the invention. In particular, the multiple modifications described in this specification can be combined as needed.

[0062] Although the above embodiment has exemplified a spoiler as an example of a resin member, the technology of the present disclosure is not limited to this and can be applied to any resin member that requires high rigidity in terms of size or shape. [Explanation of symbols]
