Description

[Technical Field]

[0001] The present invention relates to a mounting structure and an object to be mounted. [Background technology]

[0002] As an attachment structure, Patent Document 1 discloses a vehicle spoiler 20 provided at a rear portion 14 of a vehicle body 11 and extending in the vehicle width direction. The vehicle spoiler 20 includes a resin exterior member 22, which is an exterior component, and a metallic reinforcing member 23 that reinforces the exterior member 22. The reinforcing member 23 includes a reinforcing body 31 that extends rearward from the rear portion 14 of the vehicle body 11. The exterior member 22 includes an upper member 32 that extends in the vehicle width direction above the reinforcing body 31, and a lower member 33 that extends in the vehicle width direction below the reinforcing body 31. The upper member 32 and the lower member 33 are connected to the reinforcing body 31 within a hollow closed cross section 34. The reinforcing member 23, the upper member 32, and the lower member 33 include a connecting portion 64 that connects them to each other between left and right connecting portions 52, 52. The connecting portion 64 is composed of a first connecting portion 65 that directly connects the lower member 33 to the reinforcing body 31, and a second connecting portion 66 that connects the upper member 32 and the lower member 33 across the reinforcing body 31.

[0003] In the second connecting portion 66, a nut holding portion 84 is formed in the upper member 32, a reinforcing body side hole 85 is formed in the reinforcing body 31 of the reinforcing member 23, and a lower member side hole 86 is formed in the lower member 33. The nut holding portion 84 (made of resin) is composed of a base portion 91 provided on the lower surface 32a of the upper member 32, and a fitting groove (U-shaped groove) 92 that is provided in this base portion 91 and opens in the vehicle width direction. The fitting nut 87 is formed of metal, and is formed with a fitting portion 93 that fits into the fitting groove (U-shaped groove) 92 of the nut holding portion 84, and a screw hole 94 into which a fastening screw 89 is screwed. Then, a fitting nut 87 is fitted into the nut holding portion 84, and the reinforcing member 23 and lower member 33 are placed against this fitting nut 87 in that order. A fastening screw 89 is then screwed into the lower member side hole 86 and the reinforcing body side hole 85 from the lower member 33 side, thereby fastening the upper member 32, reinforcing member 23 and lower member 33 together.

[0004] [Patent Document 1] International Publication No. 2012 / 039242 Summary of the Invention [Problem to be solved by the invention]

[0005] In the mounting structure disclosed in the above-mentioned Patent Document 1, although the mounting rigidity of the vehicle spoiler 20 can be increased, the nut holding portion 84 has an opening for inserting the nut 87, and has a relatively low load-bearing capacity. Therefore, when a relatively large force is applied to the vehicle spoiler 20, stress is concentrated at the opening, and there is a risk that the surrounding area and therefore the nut holding portion 84 will be deformed.

[0006] The present invention has been made to solve the above-mentioned problems, and has an object to increase the load resistance of a mounting structure that mounts an object to be mounted to a mounting destination. [Means for solving the problem]

[0007] In order to solve the above problems, the mounting structure of the present invention is a mounting structure for mounting an object to be mounted to a mounting destination, the mounting structure comprising a mounting member for mounting the object to be mounted to the mounting destination using a fixing member, the fixing member comprising a first fixing member on the object to be mounted and a second fixing member on the mounting destination side that is engageable with the first fixing member, the mounting member comprising a base on which the first fixing member is provided, and the object to be mounted comprising a fixing portion base to which the base of the mounting member is fixed, and a fixing portion opening formed in the fixing portion base smaller than the base and through which the first fixing member can be inserted.

[0008] According to the mounting structure of this invention, an object to be mounted, in which the base of the mounting member provided with the first fixing member is fixed to the fixing portion base, can be mounted to the target by fastening the second fixing member to the first fixing member inserted through the fixing portion opening of the fixing portion base. In this case, since the base is larger than the fixing portion opening, it is firmly fixed to the target so as to cover the fixing portion opening periphery of the fixing portion base. This makes it possible to increase the rigidity of the fixing portion opening periphery used to secure the target. As a result, it is possible to further increase the load-bearing capacity of the mounting structure in which the target is mounted to the target.

[0009] In the mounting structure according to the present invention, the fixing portion opening preferably has a symmetrical shape, so that when a force is applied to the object to be mounted, the fixing portion opening has a symmetrical shape, and therefore stress is applied uniformly to the entire periphery of the fixing portion opening, making it possible to prevent stress from concentrating in one area.

[0010] In the mounting structure according to the present invention, the fixing portion base and the fixing portion opening are preferably disposed in the longitudinal center of the object to be mounted. In this way, even if the object to be mounted has an elongated shape, the load-bearing capacity of the mounting points is relatively high, so it is possible to minimize the number of mounting points, thereby reducing the cost of the mounting structure.

[0011] In addition, in the mounting structure according to the present invention, it is preferable that the mounting member further comprises a wall portion connected to the base portion, capable of contacting the object to be mounted, and receiving a force applied to the mounting member at the contact portion. This allows the force applied to the mounting member to be received not only by the base portion but also by the wall portion, i.e., the force can be distributed and received at multiple locations (increasing the receiving area), making it possible to further increase the load capacity.

[0012] In the mounting structure according to the present invention, the object to be mounted preferably comprises the mounting base having the mounting opening, a mounting wall to which the wall can be fixed, and a mounting member accommodating portion capable of accommodating the mounting member with some play. This makes it possible to maintain a high load-bearing capacity while absorbing the difference in thermal contraction between the object to be mounted and the mounting destination.

[0013] The present invention also provides an attachment object that is attached to an attachment destination by a fixing member, the attachment object comprising an attachment member for attaching to the attachment destination by the fixing member, the fixing member comprising a first fixing member on the attachment object side and a second fixing member on the attachment destination side that is engageable with the first fixing member, the attachment member comprising a base on which the first fixing member is provided, the attachment object comprising a fixing portion base to which the base of the attachment member is fixed, and a fixing portion opening in the fixing portion base that is smaller than the base and through which the first fixing member can be inserted. The attachment object according to this invention can also achieve the same effects and advantages as the above-mentioned attachment structure.

[0014] According to this invention, it is possible to further increase the load resistance of the mounting structure in which the mounting object is mounted to the mounting destination. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] An embodiment of a mounting structure and a mounting object according to the present invention will be described below with reference to the drawings. However, the present invention is not limited to this embodiment, and various modifications and improvements can be made based on the knowledge of those skilled in the art.

[0017] The mounting structure 60 is a mounting structure for mounting the rear spoiler 20, which is an object to be mounted, to the vehicle body 30, which is a destination to be mounted. The mounting structure 60 includes the rear spoiler 20 (object to be mounted), the vehicle body 30 (destination), a fastening member 40 (fixing member), and a mounting member 10.

[0018] The mounting member 10 is a member for mounting a rear spoiler 20, which is an object to be mounted, to a vehicle body 30, which is the mounting destination, using a fastening member 40, which is a fixing member. As shown in Fig. 1, the rear spoiler 20 is mounted to an upper portion of a tailgate 32 that is continuous with a roof portion 31 of the vehicle body 30, and is positioned rearward of the roof portion 31 and extends rearward from the tailgate 32. The rear spoiler 20 is formed in a horizontally elongated shape that is approximately the same size as the left-right width of the upper portion of the tailgate 32, and is formed in an elongated shape whose width in the fore-and-aft direction of the vehicle is shorter than the left-right width.

[0019] The object to be attached is not limited to the rear spoiler 20, but is preferably an automotive component such as an automotive exterior component, such as a front spoiler, or an automotive interior component. The object to be attached is not limited to synthetic resin material, but a composite material, such as carbon fiber reinforced plastic, may be used. Furthermore, the attachment destination is the vehicle body when the object to be attached is an automotive component, but is not limited to this, and may be the body of an electrical appliance, such as a printer, personal computer, or television. Furthermore, the attachment member 10 is preferably an automotive attachment member for attaching an automotive component to the vehicle body 30. Furthermore, the fixing member is not limited to the fastening member 40, but may be a rivet or an engaging member having recesses and protrusions that engage with each other.

[0020] As shown in FIGS. 3 and 4 , the rear spoiler 20 includes an upper member 21 made of synthetic resin and a lower member 22 made of synthetic resin. The upper member 21 and the lower member 22 are fixed together by, for example, vibration welding. The lower member 22 is integrally formed with a mounting member fixing portion 23 to which a mounting member 10 is fixed. The mounting member fixing portion 23 is provided to protrude outward from the lower member 22. The mounting member 10 is placed inside the mounting member fixing portion 23, and the cylindrical body 41 a of a nut member 41 fixed to the mounting member 10 is inserted into the fixing portion opening 52. A bolt member 42 is fastened to the nut member 41 from the tailgate 32 side (the vehicle body 30 side), thereby attaching the rear spoiler 20 to the tailgate 32. The upper member 21 and the lower member 22 may be fixed together by a fixing method other than vibration welding, for example, by adhesive or screw fastening.

[0021] As shown in Figures 3 and 4, the mounting member 10 includes a base 11, an opening 12, a holding portion 13, and a wall portion 15. The mounting member 10 is made of a metal material (iron, aluminum, etc.) and is formed in a dome shape (hereinafter, may be referred to as a pedestal shape) with a flat top portion. The base 11 forms the flat top portion of the mounting member 10, and the wall portion 15 forms the side portion.

[0022] The base 11 is formed in a rectangular, plate-like shape and has a circular opening 12 that is symmetrical. The opening 12 penetrates in the front-to-rear direction (thickness direction of the base 11). A holding portion 13 that holds a held portion 41c (described later, see FIG. 3B) of a nut member 41 (fixing member) is formed on an opening peripheral portion 12a of the opening 12. The front end surface of the held portion 41c of the nut member 41 contacts and is fixed to the rear end surface of the opening peripheral portion 12a (holding portion 13) of the opening 12, thereby fixing the nut member 41 to the base 11, i.e., the mounting member 10. The nut member 41 is joined to the base 11 by welding or the like. The opening 12 is not limited to a circular shape and may have any other shape (e.g., an elliptical shape) as long as it is symmetrical.

[0023] Base 11 is fixed in contact with fixing portion base 51 of mounting member fixing portion 23 of lower member 22. At this time, base 11, i.e., mounting member 10, is fixed to lower member 22 (rear spoiler 20 (mounting object)) by fastening bolt member 42 to nut member 41 (fixing member).

[0024] The wall portion 15 is connected to the base 11, is capable of contacting the inside of the mounting member fixing portion 23 of the rear spoiler 20, and receives a force applied to the mounting member 10 at the contact portion. As shown in FIG. 4 , the wall portion 15 includes an upper wall 15a, a lower wall 15b, a right wall 15c, and a left wall 15d. The upper wall 15a is connected to the upper side of the base 11. The lower wall 15b is connected to the lower side of the base 11. The right wall 15c is connected to the right side of the base 11, and has its upper side connected to the right side of the upper wall 15a and its lower side connected to the right side of the lower wall 15b. The left wall 15d is connected to the left side of the base 11, and has its upper side connected to the left side of the upper wall 15a and its lower side connected to the left side of the lower wall 15b.

[0025] The bottom wall 15b, the right wall 15c, and the left wall 15d are provided so as to form a first predetermined angle (for example, 90 degrees) with respect to the base 11. The first predetermined angle is an angle equal to or greater than 90 degrees and smaller than 180 degrees, and is set to an angle such that the outline of the mounting member 10 in a plan view is as similar in size as possible to the outer contour of the base 11. This makes it possible to reduce the size of the mounting member 10. It also makes it possible to increase the rigidity of the mounting member 10.

[0026] The upper wall 15a is provided to form a second predetermined angle (e.g., an angle greater than 90 degrees and less than 180 degrees) with respect to the base 11. The second predetermined angle is preferably set so that the shape of the mounting member fixing portion 23 is optimally suited to the shape of the back door 32. For example, the upper wall 55a of the fixing portion wall portion 55 of the mounting member fixing portion 23 is substantially flat along the shape of the back door 32, and is therefore formed to extend along the horizontal direction of the base 11 (the second predetermined angle is 180 degrees). This makes it possible to provide a mounting member 10 with an optimal shape suited to the installation location of the mounting member fixing portion 23 and the shape of the lower member 22. The upper wall 15a is formed in a stepped plate shape, and the outer end (corner) of the flange portion 41b comes into contact with the inner wall surface of the step portion 15a1, thereby restricting rotation of the nut member 41.

[0027] Furthermore, the shapes of the upper wall 15a, the lower wall 15b, the right wall 15c, and the left wall 15d are not limited to the shapes of this embodiment, and can be freely set to be optimal shapes depending on the installation location of the mounting member fixing portion 23 and the shape of the lower member 22.

[0028] As shown in Figures 3 and 4, the mounting member fixing portion 23 is formed at a predetermined location on the rear spoiler 20 to accommodate and fix the mounting member 10 therein. One or more predetermined locations are provided at locations necessary for fixing the rear spoiler 20 to the vehicle body 30. In this embodiment, as shown in Figure 5, multiple (three) mounting member fixing portions 23 are provided on the lower member 22. At least one of the mounting member fixing portions 23 (i.e., the fixing portion base 51 and the fixing portion opening 52) is preferably located in the center of the lower member 22 in the longitudinal direction. The other mounting member fixing portions 23 are located at both left and right ends of the lower member 22 in the longitudinal direction. The other mounting member fixing portions 23 provided on the left or right side are preferably located at equal intervals.

[0029] Furthermore, when mounting member fixing portion 23 is disposed in the longitudinal center of lower member 22, the other mounting member fixing portions disposed on both left and right longitudinal ends of lower member 22 may be provided with an opening (a structure having play that can absorb the difference in thermal contraction between resin and metal) having a fitting groove (U-shaped groove) 92 that opens in the vehicle width direction for inserting nut 87 into nut holding portion 84 as in the conventional method (disclosed in Patent Document 1). In this way, mounting member fixing portion 23 in the center can withstand a relatively large load, and the other mounting member fixing portions can withstand a load (relatively small load) with a conventional structure, so that it is possible to reduce the number of fastening points (fastening locations) for fastening the object to be attached to the attachment site and also to ensure reliable attachment with a simple mounting structure.

[0030] The mounting member fixing portion 23 is preferably formed according to the shape of the mounting member 10, and in this embodiment is formed so as to have a pedestal-shaped recess. As shown in Fig. 2, the mounting member fixing portion 23 mainly includes a fixing portion base 51 formed to correspond to the base 11 and contacting and holding the base 11, and a fixing portion wall 55 formed to correspond to the wall 15 and contacting and holding the wall 15. The mounting member fixing portion 23 further includes a fixing portion opening 52.

[0031] The fixing portion base 51, like the base 11, is formed in a rectangular, plate-like shape and has an elliptical fixing portion opening 52. The fixing portion opening 52 is formed on the fixing portion base 51 to be smaller than the base 11 and is formed so that the cylindrical main body 41a of the nut member 41 can be inserted therethrough. The fixing portion opening 52 preferably has a symmetrical shape. The base 11 is placed on the fixing portion base 51 with the opening 12 aligned with the fixing portion opening 52. The fixing portion opening 52 is not limited to an elliptical shape and may be a circle as long as it is larger than the outer diameter of the cylindrical main body 41a, or may be another shape (for example, a circle) as long as it is symmetrical.

[0032] The fixed portion wall portion 55 includes an upper wall 55a, a lower wall 55b, a right wall 55c, and a left wall 55d. The upper wall 55a is connected to the upper edge portion of the fixed portion base 51. The lower wall 55b is connected to the lower edge portion of the fixed portion base 51. The right wall 55c is connected to the right edge portion of the fixed portion base 51, with its upper edge portion connected to the right edge portion of the upper wall 55a and its lower edge portion connected to the right edge portion of the lower wall 55b. The left wall 55d is connected to the left edge portion of the fixed portion base 51, with its upper edge portion connected to the left edge portion of the upper wall 55a and its lower edge portion connected to the left edge portion of the lower wall 55b.

[0033] The upper wall 55a, the lower wall 55b, the right wall 55c, and the left wall 55d of the fixing portion wall 55 are provided to correspond to the upper wall 15a, the lower wall 15b, the right wall 15c, and the left wall 15d of the wall portion 15. The upper wall 15a is in contact with and fixed to the inner wall surface of the upper wall 55a, the lower wall 15b is in contact with and fixed to the inner wall surface of the lower wall 55b, the right wall 15c is in contact with and fixed to the inner wall surface of the right wall 55c, and the left wall 15d is in contact with and fixed to the inner wall surface of the left wall 55d.

[0034] Fastening member 40 is a fixing member for attaching an object to an attachment destination. As shown in Figures 3A and 3B, fastening member 40 includes nut member 41, which is a first fixing member, and bolt member 42, which is a second fixing member. Nut member 41 is provided on the side of lower member 22, which is the object to be attached, and bolt member 42 is engageable with nut member 41 and is provided on the side of back door 32, which is the attachment destination.

[0035] The nut member 41 comprises a cylindrical main body 41a, a square flange portion 41b provided coaxially on one end (rear end) of the cylindrical main body 41a, and a retained portion 41c formed on the other end surface (front end surface) of the flange portion 41b.

[0036] An internal thread is formed on the inner peripheral surface of the cylindrical main body 41a, into which the external thread of the bolt member 42 is threaded. The other end face (front end face) of the cylindrical main body 41a is preferably set to be substantially flush with the front end face of the fixed portion base 51. The other end face (front end face) of the cylindrical main body 41a may be set to be higher than the front end face of the fixed portion base 51. The nut member 41 may be formed such that the cylindrical main body 41a and the flange portion 41b are integrally formed, or the cylindrical main body 41a and the flange portion 41b are formed from separate members and joined by welding or the like.

[0037] The flange portion 41b is formed in a rectangular shape that can come into contact with any of the inner wall surfaces of the wall portion 15 of the mounting member 10 (preferably, the step portion 15a1 of the upper wall 15a or the lower wall 15b) to restrict rotation of the nut member 41. Specifically, the length of the short side (one side in the case of a square) of the rectangular flange portion 41b is set to a value that is smaller than the distance between the upper wall 15a and the lower wall 15b of the wall portion 15 and larger than the vertical width of the opening 12. The length of the long side (the diagonal in the case of a square) of the rectangular flange portion 41b is set to a value that is larger than the distance between the upper wall 15a and the lower wall 15b of the wall portion 15.

[0038] (Mounting method for attaching an object to a mounting location) First, the rear spoiler 20 is assembled. First, the mounting member 10 is attached to the mounting member fixing portion 23 of the lower member 22 (rear spoiler 20). At this time, the base portion 11 of the mounting member 10 is placed in contact with the fixing portion base portion 51 of the mounting member fixing portion 23 of the lower member 22 by aligning the opening 12 with the fixing portion opening 52 and inserting the cylindrical body 41a of the nut member 41 into the fixing portion opening 52. At this time, the mounting member 10 may be temporarily fixed to the mounting member fixing portion 23 with double-sided tape or the like.

[0039] Next, the lower member 22 to which the mounting member 10 has been attached (temporarily fixed) is bonded to the upper member 21 by vibration welding, thereby assembling the rear spoiler 20. Note that although vibration welding is performed after the nut member 41 has been attached, it can be performed before the nut member 41 is attached as long as the mounting member 10 has been temporarily fixed to the lower member 22.

[0040] Then, the rear spoiler 20 is attached to the back door 32. The rear spoiler 20 is positioned at the attachment position, and the bolt members 42 are tightened into the nut members 41 to attach the rear spoiler 20 to the back door 32.

[0041] (Variation) In the above-described embodiment, the nut member 41 is held (fixed) to the mounting member 10. However, as shown in FIGS. 6A and 6B , a bolt member 142 may be held (fixed) to the mounting member 10. In this case, the fastening member 140 includes a nut member 141 (second fixing member) and a bolt member 142 (first fixing member). The bolt member 142 includes a cylindrical main body 142a, a rectangular flange portion 142b coaxially provided on one end (rear end) of the cylindrical main body 142a, a held portion 142c formed on the other end surface (front end surface) of the flange portion 142b, and a male thread portion 142d coaxially provided on the other end surface (front end) of the cylindrical main body 142a and threadedly engaged with the nut member 141. The other end surface (front end surface) of the cylindrical main body 142a is set to be substantially flush with the front end surface of the fixing portion base 51. The flange portion 142b is formed in the same manner as the flange portion 41b described above, and the held portion 142c is formed in the same manner as the held portion 41c described above.

[0042] The mounting member 10 described above may also be provided with fixing claws and fixing holes. In this case, the fixing claws engage with recesses formed in the lower member 22, facilitating positioning of the mounting member 10 to the lower member 22 and enabling simple mounting. Rivets or the like can be inserted through the fixing holes, and by attaching the rivets to the lower member 22, the mounting member 10 can be easily mounted to the lower member 22. Note that fixing holes may be provided instead of fixing claws. The fixing holes engage with protrusions formed in the lower member 22, facilitating positioning of the mounting member 10 to the lower member 22 and enabling simple mounting.

[0043] Furthermore, in the above-described mounting member 10, the upper wall 15a is provided to extend in the horizontal direction of the base relative to the base 11, and the lower wall 15b is provided to be perpendicular to the base 11, but the lower wall 15b of the mounting member 10 may be provided to extend in the horizontal direction of the base relative to the base 11. This mounting member 10 is effective when the back surface of the lower member 22 is flat.

[0044] Furthermore, the above-described mounting structure 60 may be provided with a mounting member accommodating portion 24 capable of accommodating the mounting member 10 with some play, instead of the mounting member fixing portion 23. As shown in Fig. 7A, the mounting member accommodating portion 24 is provided in the lower member 22 and includes a fixing portion base 151 having a fixing portion opening 152, and a fixing portion wall 155 capable of fixing the wall portion 15. As shown in Fig. 7B, the left-right width of the fixing portion base 151 is set to be longer than the left-right width of the base 11. The fixing portion opening 152 is formed in the shape of a long, narrow hole that is elongated along the left-right width direction and allows the cylindrical main body 41a of the nut member 41 to be inserted therethrough.

[0045] 7B, the fixed portion wall 155 has a first wall 56a that is a wall that constantly fixes (holds) the wall 15, and a second wall 56b that is a wall that is initially positioned a predetermined distance from the wall 15. Like the fixed portion wall 55 described above, the fixed portion wall 155 has an upper wall 155a, a lower wall 155b, a right wall 155c, and a left wall 155d. The upper wall 155a and the lower wall 155b are the first wall 56a that constantly holds the upper wall 15a and the lower wall 15b, respectively. The right wall 155c and the left wall 155d are the second wall 56b that are initially positioned a predetermined distance from the right wall 15c and the left wall 15d, respectively.

[0046] Because the first wall portion 56a is constantly held (in contact with) the upper wall 15a and the lower wall 15b, it can withstand a relatively large force (particularly a force acting in the vertical direction) acting on the rear spoiler 20 of the mounting member 10, thereby increasing the load-bearing capacity of the mounting structure. Furthermore, because the second wall portion 56b is configured to accommodate the mounting member 10 with some play and the fastening portion opening 152 is configured to allow the nut member 41 to move along the longitudinal direction, the mounting member 10 can move within the mounting member accommodating portion 24 after being mounted in the mounting member accommodating portion 24. Therefore, even if the rear spoiler 20 and the rear spoiler 20 differ in length in the vehicle width direction due to a difference in thermal contraction after being mounted to the tailgate 32, the lower member 22 can move relative to the mounting member 10. As a result, even if the rear spoiler 20 (mounting object) and the tailgate 32 (mounting destination) have different thermal contractions, it is possible to maintain a high load-bearing capacity while absorbing the difference in thermal contraction.

[0047] (Actions and Effects of the Embodiments) The mounting structure 60 according to the embodiment described above is a mounting structure for mounting an object to be mounted (rear spoiler 20) to a mounting destination (vehicle body 30). The mounting structure 60 includes a mounting member 10 for mounting the rear spoiler 20 to the vehicle body 30 with fixing members (fastening members 40), the fastening members 40 including a first fixing member (nut member 41) on the rear spoiler 20 side and a second fixing member (bolt member 42) on the vehicle body 30 side that is engageable with the nut member 41, the mounting member 10 including a base 11 on which the nut member 41 is provided, and the rear spoiler 20 including a fixing portion base 51 to which the base 11 of the mounting member 10 is fixed, and a fixing portion opening 52 formed in the fixing portion base 51 smaller than the base 11 and through which the nut member 41 can be inserted.

[0048] According to the mounting structure 60 of this embodiment, the rear spoiler 20, in which the base 11 of the mounting member 10 provided with the nut member 41 is fixed to the fixing portion base 51, can be mounted to the vehicle body 30 by fastening the bolt member 42 to the nut member 41 inserted through the fixing portion opening 52 of the fixing portion base 51. At this time, since the base 11 is larger than the fixing portion opening 52, the rear spoiler 20 is firmly fixed to the fixing portion base 51 so as to cover the fixing portion opening periphery of the fixing portion opening. Furthermore, the fixing portion opening 52 can be formed relatively small, which makes it possible to suppress stress concentration in a portion of the fixing portion opening 52. This makes it possible to increase the rigidity of the periphery of the fixing portion opening 52 used to secure the rear spoiler 20. As a result, it is possible to further increase the load-bearing capacity of the mounting structure 60 that mounts the rear spoiler 20 to the vehicle body 30.

[0049] Furthermore, in the mounting structure 60 according to this embodiment, it is preferable that the fixing portion opening 52 has a symmetrical shape. According to this, when a force is applied to the rear spoiler 20, the fixing portion opening 52 has a symmetrical shape, so that stress is applied uniformly to the entire periphery of the fixing portion opening 52, making it possible to prevent stress from concentrating in one area.

[0050] Furthermore, in the mounting structure 60 according to this embodiment, the fixing portion base 51 and the fixing portion opening 52 are preferably disposed in the longitudinal center of the rear spoiler 20. In this way, even if the rear spoiler 20 has an elongated shape, the load-bearing capacity of the mounting locations is relatively high, so it is possible to minimize the number of mounting locations, and as a result, it is possible to reduce the cost of the mounting structure 60.

[0051] Furthermore, in the mounting structure 60 according to this embodiment, the mounting member 10 is preferably connected to the base 11 and further includes a wall 15 that is capable of contacting the rear spoiler 20 and that receives the force applied to the mounting member 10 at the contact portion. This allows the force applied to the mounting member 10 to be received not only by the base 11 but also by the wall 15, that is, the force can be distributed and received at multiple locations (by increasing the receiving area), thereby further increasing the load resistance.

[0052] Furthermore, in the mounting structure 60 according to this embodiment, the rear spoiler 20 preferably includes a fixing portion base 151 having a fixing portion opening 152, a fixing portion wall 155 to which the wall portion 15 can be fixed, and a mounting member accommodating portion 24 that can accommodate the mounting member 10 with some play. This makes it possible to maintain a high load-bearing capacity while absorbing the thermal contraction difference even if the thermal contraction difference between the rear spoiler 20 and the vehicle body 30 differs.

[0053] Moreover, the rear spoiler 20 according to this embodiment is a rear spoiler 20 that is attached to the vehicle body 30 with fastening members 40, and the rear spoiler 20 includes a mounting member 10 for mounting to the vehicle body 30 with the fastening members 40, the fastening members 40 including a nut member 41 on the rear spoiler 20 side and a bolt member 42 on the vehicle body 30 side that is engageable with the nut member 41, the mounting member 10 including a base 11 on which the nut member 41 is provided, and the rear spoiler 20 including a fixing portion base 51 to which the base 11 of the mounting member 10 is fixed, and a fixing portion opening 52 in the fixing portion base 51 that is smaller than the base 11 and through which the nut member 41 can be inserted. The rear spoiler 20 according to this invention can also achieve the same functions and effects as the above-described mounting structure 60. [Explanation of symbols]
