DETAILED DESCRIPTION OF THE INVENTION

[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. The first direction X in Fig. 1 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 the vehicle C, and may be a member attached to a framework or panel forming an aircraft, ship, building, or other structure.

[0010] The resin member 2 includes a first resin member 21 and a second resin member 31 facing the first resin member 21. The first resin member 21 is disposed on the structural body 4 side, and the second resin member 31 is disposed on the opposite side of the structural body 4 with the first resin member 21 in between. 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 is attached to the structure 4 by a fastening member 10. In this embodiment, 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.

[0012] The first resin member 21 includes a plate-shaped first general portion 22 (an example of a general portion) extending in the first direction X and the second direction Y, a protruding portion 23 protruding downward in the third direction Z from the first general portion 22 (the opposite direction to the arrow Z in Figure 1), and an internal connecting portion 25 connected to the second resin member 31.

[0013] The protrusion 23 has a first distal end surface 23a, which is the distal end surface on the protruding side, a front vertical wall 23b connecting the first general portion 22 and the first distal end surface 23a, and a rear vertical wall 23c connected to the first distal end surface 23a and facing the front vertical wall 23b. The protrusion 23 forms an accommodation space 23d defined by the first distal end surface 23a, the front vertical wall 23b, and the rear vertical wall 23c. The accommodation space 23d can accommodate electrical components of the vehicle C, such as brake lights, an imaging device, or various sensors.

[0014] The internal connecting portion 25 is provided in the first general portion 22 and joined to the second resin member 31 by thermal welding (see FIG. 2). However, joining is not limited to this, and may be done by screws, bolts and nuts, adhesive, double-sided tape, or other joining means.

[0015] The second resin member 31 includes a plate-shaped second general portion 32 that faces the first general portion 22 and extends in the first direction X and the second direction Y, and a folded portion 33 that is folded back from the second general portion 32. The second general portion 32 is in contact with the first general portion 22 or faces the first general portion 22 with a small gap between them. The folded 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.

[0016] The first resin member 21 and the second resin member 31 may be made of a thermoplastic resin. The thermoplastic resin is, for example, polyethylene (PE). However, the thermoplastic resin is not limited to this, and may be selected from ABS resin, polypropylene (PP), polystyrene (PS), acrylic resin, polycarbonate (PC) resin, polyamide, polyethylene terephthalate (PET), and modified polyphenylene ether (modified PPE).

[0017] The resin member 2 includes a seat 6 that protrudes from the first general portion 22 toward the structural body 4 and holds the fastening member 10. In this embodiment, a bolt 11 held by the seat 6 is inserted into a bolt hole 40 of the structural body 4. Furthermore, the bolt 11 is fastened with a nut 12 that is arranged on the opposite side of the resin member 2 across the structural body 4. In this way, the resin member 2 is fastened to the structural body 4 by the fastening member 10.

[0018] Fig. 2 is a bottom view of the resin member 2. The line AA in Fig. 2 corresponds to the cross section in Fig. 1. The resin member 2 extends in a first direction X and a second direction Y intersecting the first direction X.

[0019] 2, a plurality of seats 6 are provided in the first general portion 22 of the first resin member 21. In this embodiment, the seats 6 include a first seat 6a, a second seat 6b, a third seat 6c, and a fourth seat 6d.

[0020] The first pedestal 6a and the second pedestal 6b are arranged closer to the first end Y1 than the center between the first end Y1 on the front side of the vehicle and the second end Y2 on the rear side of the vehicle in the second direction Y. The third pedestal 6c and the fourth pedestal 6d are arranged closer to the protrusion 23 than the first pedestal 6a and the second pedestal 6b in the second direction Y. Furthermore, the third pedestal 6c is arranged closer to the first end X1 on the left side of the vehicle than the first pedestal 6a and the second pedestal 6b in the first direction X. The fourth pedestal 6d is arranged closer to the second end X2 on the right side of the vehicle than the first pedestal 6a and the second pedestal 6b in the first direction X.

[0021] FIG. 3 is an enlarged perspective view of a first pedestal 6a as an example of the pedestal 6. As shown in FIG. 3, the pedestal 6 has a plate-like portion 61 spaced apart from the first general portion 22 in the third direction Z, and leg portions 62 connecting the plate-like portion 61 and the first general portion 22. In this embodiment, the plate-like portion 61 and the leg portions 62 are plate-like and have a thickness similar to that of the first general portion 22. The plate-like portion 61 extends in the first direction X and the second direction Y. The leg portions 62 extend in the third direction Z from the end of the plate-like portion 61 to the first general portion 22 around the entire periphery of the plate-like portion 61. As a result, a space S surrounded by the plate-like portion 61, the leg portions 62, and the second general portion 32 is formed between the first resin member 21 and the second resin member 31.

[0022] In this embodiment, the plate-shaped portion 61 is formed in a stepped shape including one step. The plate-shaped portion 61 includes a first plate-shaped portion 63 spaced a first distance d1 from the first general portion 22, a second plate-shaped portion 64 spaced a second distance d2 from the first general portion 22 that is smaller than the first distance d1, and a vertical wall portion 65 connecting the first plate-shaped portion 63 and the second plate-shaped portion 64.

[0023] The plate-like portion 61 further has an insertion hole 66 into which the fastening member 10 is inserted, and an opening 67 that is continuous with the insertion hole 66 and that receives the fastening member 10 .

[0024] The insertion hole 66 is a slit provided in the first plate-shaped portion 63 and extending in the first direction X. In this embodiment, the insertion 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.

[0025] As shown in FIG. 4, the opening 67 includes a first opening 67a provided in the second plate-shaped portion 64 and penetrating in the third direction Z, and a second opening 67b provided in the vertical wall portion 65 and penetrating in the first direction X, connecting the first opening 67a and the insertion hole 66. In this embodiment, the opening 67 is defined by a third side wall 67c (see FIG. 3) connected to the first side wall 66a of the insertion hole 66 and extending in the third direction Z, a fourth side wall 67d (see FIG. 3) connected to the second side wall 66b, facing the third side wall 67c, and extending in the third direction Z, and an end wall 67e extending in the second direction Y. The third side wall 67c and the fourth side wall 67d are provided on the vertical wall portion 65. The end wall 67e is provided in the second plate-shaped portion 64 and smoothly connects to the third side wall 67c and the fourth side wall 67d. The first opening 67a is defined by an end wall 67e in the second plate-shaped portion 64, and the second opening 67b is defined by a third side wall 67c and a fourth side wall 67d in the vertical wall portion 65.

[0026] The fastening member 10 inserted through the opening 67 is held by the base 6 near the connecting wall 66c of the insertion hole 66. The fastening member 10 of this embodiment includes a shaft portion 10a extending in the third direction Z, a first disk portion 10b, and a second disk portion 10c spaced apart from the first disk portion 10b. The shaft portion 10a passes through the insertion hole 66. The shaft center O of the shaft portion 10a and therefore the fastening member 10 is disposed inside the insertion hole 66. This allows the base 6 to restrict movement of the shaft portion 10a and therefore the fastening member 10 in the first direction X and the second direction Y. The first disk portion 10b is inserted into the insertion hole 66 through the first opening 67a and the second opening 67b and is disposed in the space S. The first disk portion 10b and the second disk portion 10c are disposed with the first plate-shaped portion 63 sandwiched between them. The plate-shaped portion 61 of the base 6 restricts movement of the fastening member 10 in the third direction Z by being positioned between the first disk portion 10b and the second disk portion 10c.

[0027] 3, the connecting rib 8 is a standing wall that is provided on the first resin member 21 and protrudes toward the second resin member 31. In this embodiment, the connecting rib 8 is provided on the base 6 and protrudes to the side opposite the structure 4. The connecting rib 8 has a linear first rib 81 that extends in the first direction X, a linear second rib 82 that extends in the second direction Y, and a connecting portion 83 that connects the first rib 81 and the second rib 82. A plurality of first ribs 81, second ribs 82, and connecting portions 83 may be provided.

[0028] The connecting rib 8 of this embodiment is annular and includes a pair of first ribs 81a and 81b, a pair of second ribs 82a and 82b, and four connecting portions 83a, 83b, 83c, and 84d that connect the first rib 81 and the second rib 82. The first ribs 81a and 81b are arranged on the second surface 61b of the plate-shaped portion 61, spanning the first plate-shaped portion 63, the second plate-shaped portion 64, and the vertical wall portion 65. The second rib 82a is arranged on the second surface 61b of the plate-shaped portion 61, and is located on the first plate-shaped portion 63. The second rib 82b is arranged on the second surface 61b of the plate-shaped portion 61, and is located on the second plate-shaped portion 64. The connecting portion 83 has an arc shape that smoothly connects the first rib 81 and the second rib 82, preventing stress concentration at the corners where the first rib 81 and the second rib 82 are connected. The connecting portion 83a connects the first rib 81a and the second rib 82a. The connecting portion 83b connects the second rib 82a and the first rib 81b. The connecting portion 83c connects the first rib 81b and the second rib 82b. The connecting portion 83d connects the second rib 82b and the first rib 81a.

[0029] FIG. 5 is a plan view of the first base 6a (base 6) as viewed from the second resin member 31 side. As shown in FIG. 5, at least a portion of the insertion hole 66 is disposed in a region R between the first rib 81 and the second rib 82, which are indicated by dotted lines in FIG. 5. Specifically, the region R is sandwiched between the adjacent first rib 81 and the second rib 82, and is defined by a straight line R1 connecting adjacent ends of the first rib 81 and the second rib 82, a straight line R2 connecting distant ends of the first rib 81 and the second rib 82, and the first rib 81 and the second rib 82. In this embodiment, the region R between the first rib 81a and the second rib 82a will be described as an example. However, the region R may be the region between the first rib 81a and the second rib 82b, the first rib 81b and the second rib 82a, or the region between the first rib 81b and the second rib 82a. In this embodiment, the straight line R1 is a straight line connecting the first end 81c of the first rib 81a and the first end 82c of the second rib 82a, which are adjacent to each other. The straight line R2 is a straight line connecting the second end 81d of the first rib 81a opposite the first end 81c and the second end 82d of the second rib 82a opposite the first end 82c. The shape and area of ​​the region R are not limited to this, and may be a triangular or rectangular region depending on the angles and sizes of the first rib 81 and the second rib 82 relative to the first direction X and the second direction Y.

[0030] As described above, in this embodiment, the fastening member 10 is inserted into the insertion hole 66, and the entire resin member 2 is fastened to the structure 4 via the fastening member 10 (see FIG. 1 ). A load may be input to the base 6 having such an insertion hole 66 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. Therefore, a load is input to the plate-shaped portion 61 in the third direction Z via the fastening member 10, centered on the insertion hole 66 into which the fastening member 10 is inserted, and the plate-shaped portion 61 attempts to deform in a twisting manner, starting from the insertion hole 66. In this embodiment, the plate-shaped portion 61 is provided with a first rib 81 extending in the first direction X and a second rib 82 extending in the second direction Y, and a portion of the insertion hole 66 is disposed in a region R between the first rib 81 and the second rib 82. The first rib 81 and the second rib 82 improve the rigidity of the region R therebetween, and can suppress deformation of the plate-like portion 61 originating from the insertion hole 66. This prevents the fastening member 10 from falling off due to deformation of the plate-like portion 61, and ultimately prevents the resin member 2 from falling off from the structure 4. The first rib 81 and the second rib 82 may be provided so that the entire insertion hole 66 is disposed inside the region R.

[0031] Furthermore, the connecting rib 8 may surround the insertion hole 66 and the opening 67. In this embodiment, the insertion hole 66 and the opening 67 are disposed within an area surrounded by the annular connecting rib 8. This allows the connecting rib 8 to surround and reinforce the periphery of the insertion hole 66, and suppress twisting of the plate-like portion 61 starting from the insertion hole 66.

[0032] Returning to FIG. 4 , the connecting rib 8 is provided on a second surface 61b of the plate-shaped portion 61 opposite to the first surface 61a facing the structure 4. An end 8a of the connecting rib 8 opposite to the plate-shaped portion 61 contacts the second general portion 32. As a result, when a load is input to the resin member 2 (see FIG. 1 ) and the plate-shaped portion 61 attempts to deform from the insertion hole 66 as a starting point, the connecting rib 8 can keep the distance between the plate-shaped portion 61 and the second resin member 31 constant and suppress deformation of the plate-shaped portion 61 from the insertion hole 66 as a starting point. As a result, the connecting rib 8 can reinforce the plate-shaped portion 61 and, ultimately, the base 6, improving their rigidity.

[0033] Furthermore, at least one of the first rib 81 and the second rib 82 may contact the contact portion 34 of the second resin member 31. In this embodiment, the first protrusion amount h1 of the connecting rib 8 from the second surface 61b of the first plate-shaped portion 63 is larger than the second protrusion amount h2 of the connecting rib 8 from the second surface 61b of the second plate-shaped portion 64, and the first rib 81, the second rib 82, and the connecting portion 83 all protrude until they contact the contact portion 34 of the second resin member 31. As a result, the end portion 8a (see FIG. 4) of the connecting rib 8 is in uniform surface contact with the contact portion 34 of the second resin member 31. As a result, the connecting rib 8 can suppress deformation of the plate-shaped portion 61 and, ultimately, the base 6.

[0034] As shown in FIG. 5 , in the first direction X, a third distance d3 from the connecting wall 66c of the insertion hole 66 to the end of the plate-shaped portion 61 on the first plate-shaped portion 63 side is greater than the length s of the insertion hole 66, and preferably, the third distance d3 is at least twice the length s of the insertion hole 66. In addition, in the first direction X, a fourth distance d4 from the end wall 67e of the opening 67 to the end of the plate-shaped portion 61 on the second plate-shaped portion 64 side is approximately equal to the third distance d3. In addition, in the second direction Y, a fifth distance d5 from the first side wall 66a of the insertion hole 66 to the end of the plate-shaped portion 61 is greater than the width w of the insertion hole 66 (the distance between the first side wall 66a and the second side wall 66b), and preferably, the fifth distance d5 is at least twice the width w. A sixth distance d6 from the second side wall 66b to the end of the plate-shaped portion 61 is also the same as the fifth distance d5.

[0035] As described above, the plate-shaped portion 61 of this embodiment is wider in the first direction X and the second direction Y than the insertion hole 66 and the opening 67. This ensures a wide deformable region within the plate-shaped portion 61 when the plate-shaped portion 61 receives a load input to the resin member 2 (see FIG. 1 ) and attempts to deform in a twisting manner starting from the insertion hole 66. This increases the deformation allowance of the plate-shaped portion 61, and ultimately increases the allowable load until the insertion hole 66 deforms further and the fastening member 10 falls off.

[0036] The first rib 81 is disposed closer to the insertion hole 66 in the second direction Y than the center between the end of the insertion hole 66 and the end of the plate-shaped portion 61. A seventh distance d7 from the end of the insertion hole 66 to the first rib 81a is smaller than the fifth distance d5, and in this embodiment, the seventh distance d7 is equal to or smaller than half of the fifth distance d5. The second rib 82a disposed on the first plate-shaped portion 63 is disposed closer to the insertion hole 66 in the first direction X than the center between the end of the insertion hole 66 and the end of the plate-shaped portion 61. An eighth distance d8 from the end of the insertion hole 66 to the second rib 82a is smaller than the third distance d3, and in this embodiment, the eighth distance is equal to or smaller than half of the third distance d3. Furthermore, the second rib 82b disposed on the second plate-shaped portion 64 is disposed closer to the opening 67 in the first direction X than the center between the end of the opening 67 and the end of the plate-shaped portion 61. A ninth distance d9 from the edge of the opening 67 to the second rib 82b is smaller than the fourth distance d4, and in this embodiment, the ninth distance d9 is equal to or less than half the fourth distance d4. Note that the ninth distance d9 is equal to the eighth distance.

[0037] In this manner, in this embodiment, the insertion holes 66 and the openings 67 are surrounded by annular connecting ribs 8 that are small relative to the entire plate-shaped portion 61. This makes it possible to improve the rigidity around the insertion holes 66 and the openings 67 even when a wide deformable region is ensured in the plate-shaped portion 61, thereby suppressing deformation of the plate-shaped portion 61 and, ultimately, the base 6.

[0038] Next, the structure of the third seat 6c that differs from that of the first seat 6a will be described using Figure 6. Note that a description of the structure common to the first seat 6a and the third seat 6c will be omitted. As shown in Figure 6, the seat 6 (third seat 6c) may be provided from the first general portion 22 of the first resin member 21 to the front vertical wall 23b of the protruding portion 23.

[0039] The base 6 in this embodiment protrudes from the first general portion 22 and the front vertical wall 23b of the first resin member 21 toward the structure 4. The plate-like portion 61 of the base 6 extends at an angle relative to the first general portion 22 and the front vertical wall 23b. The end of the plate-like portion 61 on the second end Y2 side is connected to the front vertical wall 23b without the leg portion 62. The leg portion 62 is provided to surround the plate-like portion 61 except for the end of the plate-like portion 61 that is connected to the front vertical wall 23b, and extends in the third direction Z to the first general portion 22 and the front vertical wall 23b. This allows the base 6 to hold the fastening member 10 at the connection point between the first general portion 22 and the front vertical wall 23b.

[0040] In this embodiment, a part of the first rib 81 of the connecting rib 8 comes into contact with the contact portion 34 of the second resin member 31.

[0041] Second Embodiment Next, a structure of the first base 6a according to a second embodiment of the present disclosure that differs from that of the first embodiment will be described with reference to Figures 7 and 8. As shown in Figure 7, in the second embodiment, a third rib 9 is provided on the second resin member 31. The third rib 9 protrudes from the second general portion 32 of the second resin member 31 toward the first resin member 21.

[0042] 8 is a plan view showing the positional relationship between the third rib 9 provided on the second resin member 31 and the connecting rib 8 provided on the first resin member 21. In this embodiment, the third rib 9 is disposed outside the connecting rib 8 (on the opposite side of the connecting rib 8 from the insertion hole 66 and the opening 67).

[0043] The third rib 9 in this embodiment is annular and includes a pair of first linear portions 91a and 91b, a pair of second linear portions 92a and 92b, and four connecting portions 93a, 93b, 93c, and 93d connecting the first linear portion 91 and the second linear portion 92. The first linear portions 91a and 91b extend in the first direction X and contact the first ribs 81a and 81b of the connecting rib 8. The second linear portions 92a and 92b extend in the second direction Y and contact the second ribs 82a and 82b of the connecting rib 8. The four connecting portions 93a to 93d contact the four connecting portions 83a to 83d of the connecting rib 8, respectively. In other words, the third rib 9 contacts the outer peripheral surface of the connecting rib 8 over the entire circumference. As a result, when the third rib 9 receives a load input to the resin member 2 (see FIG. 1) and attempts to deform in a twisting manner starting from the insertion hole 66, it is possible to keep the distance between the plate-like portion 61 of the first resin member 21 and the second resin member 31 constant and to suppress deformation of the connecting rib 8 in a direction that spreads outward, thereby suppressing deformation of the plate-like portion 61 starting from the insertion hole 66. As a result, the third rib 9 can suppress deformation of the plate-like portion 61.

[0044] It is sufficient that at least a portion of the third rib 9 contacts the connecting rib 8, and there may be a portion that does not contact the connecting rib 8. Furthermore, although the above-described third rib 9 is a continuous ring that is slightly larger than the connecting rib 8, the present disclosure is not limited to this. That is, the third rib 9 is a continuous ring that is slightly smaller than the connecting rib 8, and may contact the connecting rib 8 from the inside of the connecting rib 8 (the side of the insertion hole 66 and opening 67 of the connecting rib 8), or may be provided partially on the inside and / or outside of the connecting rib 8 and contact the connecting rib 8.

[0045] <Third embodiment> Furthermore, a third embodiment of the present disclosure for the first base 6a will be described with reference to Fig. 9, which describes a structure different from the first and second embodiments. As shown in Fig. 9, in the third embodiment, the connecting rib 8 is not an uninterrupted, continuous ring-shaped rib, but is partially open.

[0046] The connecting rib of this embodiment has a pair of first ribs 81a and 81b, one second rib 82a, and two connecting portions 83a and 83b that connect the first rib 81 and the second rib 82. The first ribs 81a and 81b may extend beyond the connection point between the first plate-shaped portion 63 and the vertical wall portion 65 to the edge of the opening 67.

[0047] As described above, the resin member 2 is fastened to the structure 4 by the fastening member 10, and comprises: a plate-like portion 61 having an insertion hole 66 into which the fastening member 10 is inserted; a first rib 81 provided on a second surface 61b of the plate-like portion 61 opposite to a first surface 61a facing the structure 4, and extending in a first direction X on the second surface 61b; and a second rib 82 provided on the second surface 61b of the plate-like portion 61, and extending in a second direction Y intersecting the first direction X on the second surface 61b, wherein at least a portion of the opening 67 is disposed in a region R between the first rib 81 and the second rib 82.

[0048] The first rib 81 and the second rib 82 improve the rigidity of the region R therebetween, and can suppress deformation of the plate-like portion 61 originating from the insertion hole 66. This prevents the fastening member 10 from falling off due to deformation of the plate-like portion 61, even when the plate-like portion 61 is enlarged to the extent that the connecting rib 8 can be formed thereon, and therefore prevents the resin member 2 from falling off the structure 4.

[0049] The first rib 81 may be connected to the second rib 82. The first rib 81 and the second rib 82 are connected to each other to reinforce each other, thereby reinforcing the periphery of the insertion hole 66 and improving the rigidity of the plate-shaped portion 61. As a result, the first rib 81 and the second rib 82 can suppress deformation of the plate-shaped portion 61 originating from the insertion hole 66 and the opening 67.

[0050] The connecting rib 8 including the first rib 81 and the second rib 82 may be annular and surround the opening 67. This allows the connecting rib 8 to surround and reinforce the periphery of the insertion hole 66, and suppress twisting of the plate-like portion 61 starting from the insertion hole 66.

[0051] The base 6 may include a general portion (first general portion 22) and a base 6 protruding from the general portion toward the structure 4, the base 6 having the plate-like portion 61 and leg portions 62 connecting the plate-like portion 61 and the general portion, and the first rib 81 and the second rib 82 may be disposed between the opening 67 and the leg portions 62. This makes it possible to suppress deformation of the plate-like portion 61 and the base 6, even when the base 6 is enlarged to the extent that the connecting rib 8 can be formed, thereby ensuring a wide deformable region in the plate-like portion 61 of the base 6.

[0052] The resin member may include a first resin member 21 and a second resin member 31 arranged opposite the first resin member 21 with a space S between the first resin member 21, wherein the first resin member 21 has the plate-shaped portion 61, the first rib 81 and the second rib 82, the first rib 81 and the second rib 82 protruding toward the second resin member 31, and the second resin member 31 has a contact portion 34 that contacts at least one of the first rib 81 and the second rib 82.

[0053] This prevents the first rib 81 and the second rib 82 from deforming toward the second resin member 31. As a result, the connecting rib 8 can prevent deformation of the plate-like portion 61 and, ultimately, the base 6. For example, the first rib 81 and the second rib 82 can keep the distance between the first resin member 21 and the second resin member 31 constant and prevent deformation of the plate-like portion 61 starting from the insertion hole 66.

[0054] 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 arbitrarily combined as necessary.

[0055] In the above embodiment, the plate-like portion 61 is spaced apart from the first general portion 22 in the third direction Z, but the present disclosure is not limited to this. That is, the plate-like portion 61 may be provided on the same plane as the first general portion 22. For example, the first general portion 22 may not be provided with a seat 6. In this case, the plate-like portion 61 is part of the first general portion 22, and the fastening member 10 is inserted into an insertion hole 66 provided in the first general portion 22. In this embodiment, although a connecting rib 8 is provided around the insertion hole 66, a leg portion 62 may not be provided around the insertion hole 66.

[0056] Although the above embodiment has been described with reference to 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.
