[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0010] 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.

[0011] 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.

[0012] The first resin member 21 includes a plate-shaped first general portion (an example of a general portion) 22 extending in the first direction X and the second direction Y, a protruding portion 23 protruding downward from the first general portion 22 (in the opposite direction to the third direction Z in FIG. 1 ), and an internal connecting portion 25 connected to the second resin member 31. Note that the first general portion 22 may have a portion that extends at an angle with respect to the first direction X and the second direction Y in accordance with the external appearance of the vehicle C and the shape of the structure 4.

[0013] 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 general 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.

[0014] The internal connecting portion 25 is provided in the first general portion 22 and joined to the second resin member 31. In this embodiment, the internal connecting portion 25 has a joining portion 25a that is arranged spaced apart from the first general portion 22 in the third direction Z, and a joining portion 25b that joins the joining portion 25a and the first general portion 22. The joining portion 25a is joined to the second resin member 31 by thermal welding. 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-back portion 33 that is folded back from the second general portion 32. The second general portion 32 faces the first general portion 22 with a gap therebetween. The folded-back portion 33 is hooked onto the rear vertical wall 23c of the first resin member 21. This locks the second resin member 31 to the first resin member 21. Note that the second general portion 32 may also have a portion that extends at an angle with respect to the first direction X and the second direction Y, depending on the appearance of the vehicle C and the shapes of the structure 4 and the first general portion 22.

[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, 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).

[0017] The first resin member 21 further includes a base 6 to which the fastening member 10 is attached. The base 6 is provided in the first general portion 22 of the first resin member 21 and protrudes toward the structural body 4. The fastening member 10 is inserted into a bolt hole 40 in the structural body 4 and fastened with a nut 12 arranged on the opposite side of the structural body 4 from the resin member 2. In this way, the resin member 2 is fastened to the structural body 4 by the fastening member 10.

[0018] Fig. 2 is a plan view of the first resin member 21 as seen from the side of the structure 4. 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.

[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). As shown in Fig. 3(b), the first general portion 22 is inclined at an angle θ with respect to the second direction Y at the location where the first seat 6a is located. The configuration of the seat 6 will be described below using the first seat 6a as an example.

[0020] The base 6 has a base plate 61 spaced apart from the first general portion 22 in the third direction Z, and a side wall 62 connecting the base plate 61 to the first general portion 22. In this embodiment, the base plate 61 and the side wall 62 are plate-shaped and have a thickness similar to that of the first general portion 22.

[0021] The base plate 61 extends in a first direction X and a second direction Y. As shown in Fig. 3(a), 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.

[0022] The side wall 62 connects the first end 61a to the third end 61c of the base plate 61 to the first general portion 22. The side wall 62 has a first side wall 62a connecting the first end 61a to the first general portion 22, a second side wall 62b facing the first side wall 62a and connecting the second end 61b to the first general portion 22, and a third side wall 62c connecting the first side wall 62a to the second side wall 62b and connecting the third end 61c to the first general portion 22. As shown in FIG. 3(b), a space M surrounded by the base plate 61 and the side wall 62 is formed in the first resin member 21.

[0023] Returning to FIG. 3(a), the base 6 further has a through hole 66 into which the fastening member 10 is inserted. The through hole 66 is a slit provided in the base plate 61 and extending in the first direction X. The through hole 66 opens on the side of the fourth end 61d of the base plate 61. In this embodiment, the through 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.

[0024] The first resin member 21 has an opening 7 provided in the first general portion 22 adjacent to the base 6. The opening 7 penetrates the first general portion 22 in the third direction Z. In this embodiment, the opening 7 is defined by a first opening inner wall 7a, a second opening inner wall 7b facing the first opening inner wall 7a, and a third opening inner wall 7c connecting the first opening inner wall 7a and the second opening inner wall 7b.

[0025] Next, the fastening member 10 attached to the base 6 will be described. The fastening member 10 is made of a metal that is more rigid than the resin member 2. The material of the fastening member 10 is, for example, iron, stainless steel, titanium, or other metal materials. The resin member 2 with the fastening member 10 attached is configured by attaching the fastening member 10, which is separate from the resin member 2, to the base 6.

[0026] Fig. 4(a) is a perspective view showing the fastening member 10, and Fig. 4(b) is a side view of the fastening member 10. As shown in Fig. 4(a), 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, a first standing wall 10d extending from the second flange 10c, and a second standing wall 10e extending from the second flange 10c and facing the first standing wall 10d.

[0027] As shown in FIG. 4(b), the shaft 10a includes a fastening portion 110 for fastening to the structure 4, and an intermediate portion 111 located between the first flange 10b and the second flange 10c. The fastening portion 110 in this embodiment has a male thread on its outer surface. The outer diameter of the intermediate portion 111 is larger than the outer diameter of the fastening portion 110, but this is not limited thereto, and the outer diameter of the intermediate portion 111 may be smaller than or the same as the fastening portion 110.

[0028] 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 (arrows a and b in FIG. 4). In this embodiment, the first flange 10b has a rectangular shape that is perpendicular to the central axis O of the shaft 10a. However, the shape of the first flange 10b is not limited thereto, and may be a polygonal shape other than a circle or a square. The first flange 10b includes a first surface S1 that faces the second flange 10c (see FIG. 4(b)).

[0029] The second flange 10c has a rectangular shape that extends in a direction intersecting the central axis O of the shaft 10a and is slightly larger than the base plate 61 of the base 6 (see FIG. 3). The second flange 10c is disposed at a distance from the first flange 10b in the direction of the central axis O of the shaft 10a. The second flange 10c includes a first end 101, a second end 102 opposite the first end 101, a third end 103 connecting the first end 101 and the second end 102, and a fourth end 104 connecting the first end 101 and the second end 102 and opposite the third end 103. The second flange 10c includes a second surface S2 that faces the first flange 10b (see FIG. 4(b)).

[0030] The second flange 10c may be fixed so as not to move relative to the shaft 10a, or may be movable along the central axis O relative to the shaft 10a. In this embodiment, the second flange 10c includes a through hole having an inner diameter slightly larger than the outer diameter of the shaft 10a. When the shaft 10a is inserted into the through hole, the second flange 10c is attached to the shaft 10a so as to be movable along the central axis O of the shaft 10a. This allows the second flange 10c to move toward the first flange 10b when tightened with the nut 12, and the base plate 61 can be tightened by the second flange 10c and the first flange 10b.

[0031] Furthermore, the shaft 10a may or may not have a retainer that prevents the second flange 10c from coming off the shaft 10a. The retainer may be, for example, a rubber plate fixed to the shaft 10a. The retainer can prevent the second flange 10c from coming off the shaft 10a during the work of attaching the resin member 2 to the structure 4, improving workability.

[0032] The first standing wall 10d extends from the first end 101 of the second flange 10c toward the first flange 10b. As shown in FIG. 4(b), the first standing wall 10d is continuous with the second surface S2 of the second flange 10c and includes a third surface S3 facing the intermediate portion 111 of the shaft 10a. The first standing wall 10d is inclined in a direction away from the central axis O of the shaft 10a (the opposite direction of arrow b). An end 106 of the first standing wall 10d on the first flange 10b side is located farther from the second flange 10c in the direction of the central axis O of the shaft 10a (the direction of arrow c) than the first surface S1 of the first flange 10b. The end 106 of the first standing wall 10d is spaced a first distance d1 from the second surface S2 of the second flange 10c along the central axis O. In this embodiment, the first distance d1 is slightly greater than the distance d0 between the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c.

[0033] The second standing wall 10e extends from the second end 102 of the second flange 10c toward the first flange 10b and faces the first standing wall 10d. The second standing wall 10e is continuous with the second surface S2 of the second flange 10c and includes a fourth surface S4 facing the intermediate portion 111 of the shaft 10a. The second standing wall 10e is inclined in a direction away from the central axis O of the shaft 10a (in the direction of arrow b). An end 107 of the second standing wall 10e on the first flange 10b side is located farther from the second flange 10c than the first flange 10b in the direction of the central axis O of the shaft 10a (in the direction of arrow c). The end 107 of the second standing wall 10e is spaced a second distance d2 from the second surface S2 of the second flange 10c along the central axis O. In this embodiment, the second distance d2 is greater than the distance d0 between the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c, but is not limited to this and may be equal to or smaller than the distance d0.

[0034] Next, a state in which the fastening member 10 is attached to the base 6 (hereinafter referred to as the attached state) will be described with reference to Figure 3. The fastening member 10 is inserted into the through-hole 66 in the direction of the black arrow in Figure 3(a). As a result, as shown in Figure 3(a), the fastening member 10 is arranged so that the first standing wall 10d is located on the first side wall 62a side and the second standing wall 10e is located on the second side wall 62b side.

[0035] 3(b), in the attached state, the shaft 10a of the fastening member 10 is inserted into the through-hole 66. In this embodiment, the central axis O is disposed within the through-hole 66 along the third direction Z, and the middle portion 111 of the shaft 10a is disposed within the through-hole 66. In this way, the base 6 restricts movement of the shaft 10a, and therefore the fastening member 10, in the first direction X and the second direction Y.

[0036] Furthermore, the first flange 10b is located inside the space M 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. That is, the first surface S1 of the first flange 10b and the second surface S2 of the second flange 10c sandwich the base plate 61 in the third direction Z. As a result, the first flange 10b and the second flange 10c restrict movement of the fastening member 10 in the third direction Z relative to the base plate 61 and therefore relative to the base 6.

[0037] Additionally, the second flange 10c is located on the resin member 2 (see FIG. 1) side, which is opposite the nut 12 with the structure 4 sandwiched between them in the third direction Z. As a result, the second flange 10c and the nut 12 (see FIG. 1) sandwich the structure 4 in the third direction Z, restricting movement of the fastening member 10 and therefore the resin member 2 relative to the structure 4 in the third direction Z.

[0038] Furthermore, the second flange 10c is movable in the direction of the central axis O of the shaft 10a. This allows the second flange 10c to move in the third direction Z, and when the fastening member 10 is tightened with the nut 12 (see FIG. 1), the second flange 10c can tighten the base plate 61 together with the first flange 10b.

[0039] In the attached state, the first standing wall 10d is aligned with the first side wall 62a. The third surface S3 of the first standing wall 10d faces the first side wall 62a. A gap α is formed between the end 106 of the first standing wall 10d and the first general portion 22.

[0040] In the attached state, the second standing wall 10e is aligned with the second side wall 62b. The fourth surface S4 of the second standing wall 10e faces the second side wall 62b. The end 107 of the second standing wall 10e is spaced apart from the first general portion 22.

[0041] The fastening member 10 sandwiches the base 6 between the first standing wall 10d and the second standing wall 10e in the second direction Y. Furthermore, in this embodiment, the third surface S3 of the first standing wall 10d is in surface contact with the first side wall 62a, and the fourth surface S4 of the second standing wall 10e is in surface contact with the second side wall 62b. This increases the coefficient of friction between the first standing wall 10d and the first side wall 62a and the coefficient of friction between the second standing wall 10e and the second side wall 62b, thereby restricting movement of the fastening member 10 relative to the base 6 in the first direction X.

[0042] Next, the effects of the fastening member 10 and the resin member 2 with the fastening member 10 according to this embodiment will be described with reference to FIG. 5. As shown in FIG. 5, in this embodiment, the fastening member 10 is inserted into the through-hole 66 of the base 6, and the resin member 2 is fastened to the structure 4 by the fastening member 10. Such a base 6 may be subjected to an unintended load P in a direction that causes the resin member 2 to be peeled off from the structure 4 due to, for example, an object colliding with the resin member 2. The load P is, for example, a thrust load that thrusts the resin member 2 upward (in the direction opposite to the arrow Z) on the rear side (the second direction Y side) of the resin member 2. The first general portion 22 is deformed by the load P so as to warp upward (in the direction of the arrow Z). As a result, a force acts on the base plate 61, causing the base plate 61 to rotate downward (in the direction opposite to the arrow Z) and backward (in the direction of the arrow Y). In response to this force, the front portion Wf of the base plate 61 located in front of the fastening member 10 (opposite direction of arrow Y) attempts to move in a direction approaching the fastening member 10, while the rear portion Wr of the base plate 61 located behind the fastening member 10 (direction of arrow Y) attempts to move in a direction away from the fastening member 10. Furthermore, the first side wall 62a and the second side wall 62b connected to these also attempt to move rearward together with the base plate 61.

[0043] In this embodiment, in the attached state, the first standing wall 10d of the fastening member 10 is disposed rearward (in the direction of arrow Y) from the first side wall 62a of the base 6. When a load P is input, the first standing wall 10d presses from behind the first side wall 62a, which tends to rotate rearward and downward (in the direction opposite to the arrow Z) in response to the rear portion Wr of the base plate 61. As a result, even if the first general portion 22, which is located rearward of the base 6, moves upward (in the direction of arrow Z), the rear portion Wr of the base plate 61 and the first side wall 62a are restricted from moving by the first flange 10b, the second flange 10c, and the first standing wall 10d of the fastening member 10. As a result, the first standing wall 10d, and therefore the fastening member 10, suppress deformation of the base 6 and prevent the resin member 2 from falling off the structure 4.

[0044] Furthermore, the end 106 of the first standing wall 10d is located farther from the second flange 10c than the first surface S1 of the first flange 10b. As a result, the first side wall 62a is located between the end face of the first flange 10b and the first standing wall 10d in the second direction Y. As a result, movement of the first side wall 62a in the second direction Y is restricted between the first flange 10b and the first standing wall 10d.

[0045] Furthermore, in this embodiment, a gap α is provided between the end 106 of the first standing wall 10d and the first general portion 22. This prevents the end 106 of the first standing wall 10d from hitting the first general portion 22, and prevents stress concentration at the connection point between the first side wall 62a and the first general portion 22.

[0046] Furthermore, in this embodiment, in the attached state, the second standing wall 10e of the fastening member 10 is disposed in front of the second side wall 62b of the base 6 (in the opposite direction to the arrow Y). As a result, the front portion Wf of the base plate 61 is sandwiched between the first flange 10b and the second flange 10c in the third direction Z, and the second side wall 62b is disposed between the end face of the first flange 10b and the second standing wall 10e in the second direction Y. Therefore, movement of the front portion Wf of the base plate 61 and the second side wall 62b is restricted between the first flange 10b, the second flange 10c, and the second standing wall 10e of the fastening member 10. As a result, the second standing wall 10e, and therefore the fastening member 10, suppress deformation of the base 6 and can prevent the resin member 2 from falling off from the structure 4.

[0047] Next, a second embodiment of the present disclosure will be described with reference to Fig. 6. Note that, in the following, a description of the configuration common to the first embodiment will be omitted, and only the different parts will be described.

[0048] The first standing wall 10d of the fastening member 100 of the second embodiment has a first protrusion 10f (an example of a protrusion) that protrudes toward the shaft 10a. The first protrusion 10f of this embodiment is a protruding portion provided on the third surface S3 of the first standing wall 10d. As a result, the first protrusion 10f increases the coefficient of friction between the first standing wall 10d and the first side wall 62a (see FIG. 3) of the base 6, thereby suppressing movement of the first side wall 62a. The first protrusion 10f is not limited to a protruding stripe, and may have any shape that increases the coefficient of friction with the third surface S3 of the first standing wall 10d. For example, the first protrusion 10f may have a grain-like pattern, multiple protrusions, or the like provided on the third surface S3.

[0049] Furthermore, in this embodiment, the second standing wall 10e has a second protrusion 10g that protrudes toward the shaft 10a. The second protrusion 10g is a protruding stripe that is provided on the fourth surface S4 of the second standing wall 10e and has the same shape as the first protrusion 10f. As a result, the second protrusion 10g increases the coefficient of friction between the second standing wall 10e and the second side wall 62b (see FIG. 3) of the base 6, thereby suppressing movement of the second side wall 62b. Like the first protrusion 10f, the second protrusion 10g is not limited to a protruding stripe, and may have any shape that increases the coefficient of friction with the fourth surface S4 of the second standing wall 10e. For example, the second protrusion 10g may have a grained pattern or multiple protrusions provided on the fourth surface S4.

[0050] As described above, the fastening member 10 or the resin member 2 with the fastening member 10 according to this embodiment can achieve the following effects.

[0051] A fastening member 10 comprising a shaft 10a, a first flange 10b connected to the shaft 10a, a second flange 10c connected to the shaft 10a and facing the first flange 10b, and a first standing wall 10d extending from the second flange 10c toward the first flange 10b.

[0052] This fastening member 10 can face a member to which the fastening member 10 is attached (for example, a resin member 2 in this embodiment) not only with a first flange 10b and a second flange 10c that face each other, but also with a first standing wall 10d that extends in a different direction from the second flange 10c. Therefore, when the member to which the fastening member 10 is attached attempts to move or deform under load, at least one of the first flange 10b, the second flange 10c, and the first standing wall 10d of the fastening member 10 abuts against the member, thereby restricting the movement or deformation of the member. As a result, the fastening member 10 can suppress deformation of the member to which the fastening member 10 is attached.

[0053] The fastening member 10 may further include a second standing wall 10e that faces the first standing wall 10d and extends from the second flange 10c toward the first flange 10b.

[0054] As a result, when the member to which the fastening member 10 is attached attempts to move or deform under load, either the first flange 10b, the second flange 10c, the first standing wall 10d or the second standing wall 10e abuts against the member, thereby restricting the movement or deformation of the member.

[0055] In addition, the fastening member 10 may be configured such that the end 106 of the first standing wall 10d on the first flange 10b side is located farther from the second flange 10c than the first flange 10b in the direction of the center (central axis O) of the shaft 10a.

[0056] This allows the first standing wall 10d and a portion of the second flange 10c to face each other in the direction of the central axis O, and allows a portion of the member to which the fastening member 10 is attached to be sandwiched between the first standing wall 10d and the second flange 10c in a direction different from the direction in which the member is sandwiched between the first flange 10b and the second flange 10c. This allows the first standing wall 10d and the second flange 10c to restrict the movement or deformation of the member when the member to which the fastening member 10 is attached attempts to move or deform under load.

[0057] Furthermore, the first standing wall 10d may have a protrusion (first protrusion) 10f that protrudes toward the shaft 10a. This allows the protrusion 10f to increase the coefficient of friction between the first standing wall 10d and a member to which the fastening member 10 is attached. This allows the protrusion 10f to restrict movement or deformation of the member to which the fastening member 10 is attached.

[0058] The resin member 2 has a fastening member 10 attached to a base 6 provided on the resin member 2, and the fastening member 10 comprises an axis 10a, a first flange 10b connected to the axis 10a, a second flange 10c connected to the axis 10a and facing the first flange 10b, and a first standing wall 10d extending from the second flange 10c toward the first flange 10b. The base 6 has a through hole 66 into which the axis 10a is inserted, and comprises a base plate 61 arranged between the first flange 10b and the second flange 10c, and a first side wall 62a located on the side of the first standing wall 10d, connecting the base plate 61 and a general portion (first general portion 22) of the resin member 2 located around the base 6.

[0059] As a result, even if the first general portion 22 positioned around the base 6 moves upward (in the direction of arrow Z), the base plate 61 and the first side wall 62a are restricted from moving between the first flange 10b, the second flange 10c, and the first standing wall 10d of the fastening member 10. As a result, the first standing wall 10d, and therefore the fastening member 10, suppress deformation of the base 6 and prevent the resin member 2 from falling off the structure 4.

[0060] 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.

[0061] In the above embodiment, the fastening member 10 is a bolt having a male thread, but the present disclosure is not limited to this. That is, the fastening member 10 may be a hollow shaft having a female thread, and may be fastened by inserting a male screw arranged on the opposite side of the resin member 2 across the structure 4.

[0062] In the above embodiment, the base 6 protruding from the first general portion 22 and having the side wall 62 has been described as an example, but the present disclosure is not limited to this. That is, the base 6 may be disposed adjacent to the protruding portion 23, and the first end 61a, the second end 61b, or the third end 61c may be connected to the front vertical wall 23b of the protruding portion 23 without the side wall 62 interposed therebetween.

[0063] Furthermore, although the above embodiment illustrates an interior member of a vehicle as an example of a resin product, the technology of the present disclosure is not limited thereto and can be applied to any resin product that requires high rigidity in terms of size or shape.
