Summary of the Invention

Problems to be Solved by the Invention

[0004] As a spoiler attached to the upper part of the tailgate, a type of vehicle is known in which an opening is recessed in the middle part in the vehicle width direction of the spoiler body and a high-mount stop lamp (hereinafter also referred to as a stop lamp) is attached. On the other hand, even in the same vehicle model, there are cases where a hole is directly formed in the tailgate without attaching a spoiler as an accessory part, and a stop lamp is attached. In this case, there are two types of tailgates: one in which a hole for mounting a stop lamp is formed and the other in which no hole for attaching a spoiler is formed. Depending on the vehicle model, when attaching a spoiler, the fastening part of the tailgate may be set while avoiding the middle part in the vehicle width direction where a hole is formed.

[0005] A predetermined single-piece rigidity is required for the spoiler body. However, when injection molding is adopted due to molding constraints, it is difficult to improve the strength compared to blow molding. Therefore, the single-piece rigidity of the spoiler body may be reduced. Therefore, the mounting rigidity of the spoiler itself is set to such an extent that it will not be displaced vertically even if an external force is applied in the vertical direction while it is attached to the vehicle.

[0006] Furthermore, the spoiler body, which is a common component, has the stop lamp mounted in the middle section, which is closer to the inside than the outside in the vehicle width direction, and the weight of the stop lamp is applied to the middle section in the vehicle width direction. Furthermore, while fastening points are easily provided on the outer side in the vehicle width direction because they are close to the steel plate end, the central side in the vehicle width direction is far from the steel plate end and has a bag-like shape. Therefore, fastening points are difficult to provide, and it is necessary to increase the mounting rigidity on the central side in the vehicle width direction. Therefore, the objective of this invention is to provide a rear vehicle structure that improves the ease of installing a spoiler while ensuring the desired mounting rigidity by securing fastening points on the center side in the vehicle width direction. [Means for solving the problem]

[0007] To solve the aforementioned problems, the vehicle rear structure of the present invention is a vehicle rear structure in which a spoiler consisting of a spoiler body extending in the vehicle width direction and a spoiler component separate from the spoiler body is attached to the upper part of the vehicle's tailgate. The spoiler body includes a mounting portion provided in the middle of the spoiler body in the vehicle width direction to which the spoiler component is attached, and a plurality of mounting portions for attaching the spoiler to the upper part of the tailgate. The plurality of mounting portions have clip fixing portions that are fixed using clips and screw fixing portions that are fixed using screws, with the screw fixing portions being positioned closer to the mounting portions than the clip fixing portions. Furthermore, a screw is provided at the outer end of the mounting part in the vehicle width direction, and is inserted diagonally from the inner side in the vehicle width direction toward the outer side in the vehicle width direction. It is characterized by the following. [Effects of the Invention]

[0008] According to the present invention, a rear vehicle structure is provided that can improve the ease of installing a spoiler while ensuring the desired mounting rigidity by securing fastening points on the center side in the vehicle width direction. [Brief explanation of the drawing]

[Figure 7] This is a front view of the grommet member. [Modes for carrying out the invention]

[0010] Hereinafter, one embodiment of the present invention will be described with reference to the drawings as appropriate. The same reference numerals will be used for identical components, and redundant descriptions will be omitted.

[0011] In this embodiment, the rear structure of the vehicle is such that a spoiler 3 is attached to the upper part 2 of the tailgate of the vehicle 1, along the width direction of the vehicle, as shown in Figure 1. The spoiler 3 mainly consists of a spoiler body 4 that extends in the width direction of the vehicle, and a high-mounted stop lamp (hereinafter also referred to as a stop lamp) 5 which is a spoiler component separate from the spoiler body 4.

[0012] The spoiler body 4 is equipped with a mounting section 7 on which a stop lamp 5 is attached. The mounting section 7 is recessed in the middle section 6 in the vehicle width direction of the spoiler body 4. Depending on the model, the mounting section 7 can be selectively fitted with either a stop lamp 5 or a cover member (not shown) as a spoiler component.

[0013] The spoiler body 4 is equipped with multiple mounting points 10 for attaching the spoiler 3 to the upper part 2 of the tailgate. The attachment part 10 has a clip fixing part 11 fixed using a clip 14 and a screw fixing part 12 fixed using a screw 15. Two clip fixing parts 11 are provided on each of the left and right sides. The clip 14 is inserted through and locked into clip holes formed in the front wall part of the spoiler main body 4 and the upper part of the tailgate 2.

[0014] Also, the screw fixing part 12 is arranged on the mounting part 7 side rather than on the clip fixing part 11 side. Furthermore, the attachment part 10 of the present embodiment has a pair of bolt fixing parts 13 that fix each end part in the vehicle width direction of the spoiler main body 4 using bolts 16 inserted from above or below. And the attachment part 10 has the clip fixing parts 11, 11, the screw fixing part 12, and the bolt fixing parts 13 arranged at intervals in a left - right symmetric and substantially equal - interval manner in the vehicle width direction. Note that the pair of bolt fixing parts 13 bolt - fix both end parts of the spoiler main body 4 to the vehicle body in the vertical direction. Thereby, the attachment strength can be further improved. However, not limited to the present embodiment, in order to suppress an increase in the number of parts, a configuration without the bolt fixing parts 13 may be adopted.

[0015] As shown in FIG. 2, a pair of screw fixing parts 12 are provided symmetrically on the left and right outer ends 7a in the vehicle width direction of the mounting part 7. In FIG. 2, the left side in the vehicle width direction of the mounting part 7 is shown enlarged, and the right side in the vehicle width direction is omitted. The right side of the mounting part 7 has the same configuration as the left side and is symmetric. Therefore, here, the left side in the vehicle width direction of the mounting part 7 will be mainly described.

[0016] As shown in FIG. 3, the screw 15 is inserted obliquely from the inner side in the vehicle width direction toward the outer side in the vehicle width direction in the screw fixing part 12. In the present embodiment, the axis BL of the screw 15 is inclined at a predetermined inclination angle α from the inner side to the outer side with respect to a reference line CL along the vehicle front - rear direction.

[0017] The screw fixing portion 12 includes a seating surface portion 20, an opening 21 provided adjacent to the seating surface portion 20, and a grommet member 22 that is attached to the seating surface portion 20 through the opening 21. Of these, the seat portion 20 has a flat surface that bulges forward by a predetermined distance from the front wall portion 4a of the spoiler body 4, and is positioned parallel to the front wall portion 4a. Furthermore, the seat portion 20 is formed in a bag shape by opening the outer end 20b of the seat portion 20 in the vehicle width direction.

[0018] The opening 21 is provided in the front wall portion 4a adjacent to the rear of the seat portion 20. The size of the opening 21 is set so that the grommet member 22 can be slid in the vehicle width direction and installed from the end 20b side.

[0019] The grommet member 22 has a pair of clamping pieces 23 and 24 that clamp the seat surface 20 from the front and rear, and a connecting portion 25 that connects the pair of clamping pieces 23 and 24. The grommet member 22 also has a locking portion 26 that protrudes forward from the front clamping piece 23 and engages with the upper part 2 of the tailgate. The pair of clamping pieces 23, 24 and the seating surface 20 each have a screw hole 27, a through hole 28, and an insertion hole 20a formed in communication with an inclined angle α through which a screw 15 is inserted. As shown in Figure 3, the inner circumferential surface of the screw hole 27 has a female threaded portion 27a into which the inserted screw 15 is screwed.

[0020] The connecting portion 25 is formed in a roughly U-shape in plan view, with each end connected to the clamping pieces 23 and 24, respectively. The connecting portion 25 is elastically deformable, allowing the clamping pieces 23 and 24, which are arranged parallel to each other at a predetermined interval, to move closer together and further apart. As shown in Figure 4, the engaging portion 26 has a pair of upper and lower engaging portions 26a, 26a. The engaging portion 26a is tapered in width towards the tip (see Figure 5), and engaging grooves 26c and retaining pieces 26d are formed on the upper and lower outer surfaces 26e, respectively.

[0021] Of these, the engagement groove 26c is recessed on the outer surface of the engagement portion 26a on the side of the clamping piece 23, and is formed to engage with the peripheral edge 2b of the engagement hole 2a. Furthermore, in this embodiment, a packing member 50 that can be compressed and deformed is provided around the periphery of the engaging portion 26. The engaging portion 26 is inserted through an insertion hole formed in the center of the packing member 50 in a plan view. When inserted, the engaging groove 26c is formed to engage with the periphery of the insertion hole of the packing member 50.

[0022] Furthermore, the retaining piece 26d is elastically deformable and has a roughly triangular shape, and is formed on the tip side of the engagement portion 26a, rather than on the engagement groove 26c (see Figure 6). As shown in Figure 7, each retaining piece 26d is integrally formed with its tip inclined in the opposite direction in the vehicle width direction, and in a direction approaching the outer surface 26e. When the spoiler body 4 is attached to the upper part 2 of the tailgate, the engaging portion 26 is inserted into the insertion hole of the packing member 50 in advance and fitted into the engaging groove 26c, as shown in Figure 5. At this time, the retaining piece 26d abuts against the front side of the attached packing member 50 to hold the packing member 50 in place so that it does not fall off.

[0023] Furthermore, when inserting the engagement portion 26 into the engagement hole 2a from the rear to the front of the vehicle, the retaining piece 26d tilts further toward the outer surface 26e. This allows for easy insertion of the engagement portions 26a, 26a into the engagement hole 2a. Then, as shown in Figure 4, when the spoiler body 4 is attached to the upper part 2 of the tailgate, the peripheral edge 2b of the engagement hole 2a is engaged with and fixed in the engagement groove 26c. In this process, each retaining piece 26d elastically returns to its original position and is locked to the front peripheral edge of the engagement hole 2a. As shown in Figure 3, the packing member 50 is sandwiched between the upper part 2 of the tailgate and the front clamping piece 23 to seal the periphery of the engagement hole 2a.

[0024] As shown in Figure 5, these upper and lower engaging portions 26a, 26a are arranged at a predetermined distance apart in the vertical direction. On the opposing surfaces between the engaging portions 26a, 26a, there are obliquely recessed semicircular guide grooves 26f that allow the outer surface of the inserted screw 15 to slide against them (see Figure 7). Then, a screw 15 is inserted diagonally from the rear to the front of the vehicle through the screw holes 27, through holes 28, and insertion holes 20a of the pair of clamping pieces 23, 24 and the seating surface 20. At this time, a portion of the tip of the screw 15 is inserted between the pair of engaging parts 26a, 26a. As a result, deformation in the direction that brings the engaging portions 26a, 26a closer together is prevented by the screw 15.

[0025] As shown in Figure 3, cylindrical boss portions are formed at an angle or perpendicularly on the opposing surfaces between the clamping pieces 23 and 24. Each boss portion has a screw hole 27 and a through hole 28 into which a screw 15 is inserted, and annular sealing portions 29 and 30 (see Figure 6) that protrude around the respective screw holes 27 and through holes 28 on the opposing surfaces of the boss portion. As shown in Figure 3, the sealing portions 29 and 30 are designed to have a strength such that they collapse when they come into contact with each other after deforming from a separated state between the clamping pieces 23 and 24 in the direction of approaching each other. As a result, the areas around the screw hole 27 and through hole 28 are sealed by the sealing portions 29 and 30. Furthermore, the sealing portions 29 and 30 only need to be provided on at least one of the opposing surfaces and configured to abut against the other of the pair of clamping pieces 23 and 24.

[0026] Furthermore, as shown in Figure 6, the annular sealing portion 31 has a boss portion that protrudes diagonally from the rear surface 24a of the rear clamping piece 24. On the rear surface of the boss portion, the annular sealing portion 31 is provided around the through hole 28 shown in Figure 3. The sealing portion 31 is configured to seal the space between the through hole 28 and the screw 15 by being compressed around the through hole 28 when the back side of the head 15a of the screw 15 comes into contact with it.

[0027] Furthermore, as shown in Figure 4, the grommet member 22 of the embodiment has elastically deformable lip portions 40 that protrude outward from the upper and lower outer end faces of the clamping piece 23 located on the front side. The tip 41 of the lip portion 40 is elastically in contact with the periphery of the insertion hole 20a (see Figure 3) of the seat portion 20 from the front of the vehicle.

[0028] Next, the effects of the vehicle rear structure of this embodiment will be explained in accordance with the installation order of the spoiler 3. In this embodiment, as shown in Figure 1, the spoiler body 4 is attached to the upper part 2 of the tailgate using the mounting part 10. As shown in Figure 2, a pair of left and right screw fixing parts 12 located at the outer ends 7a in the vehicle width direction of the mounting part 7 of the spoiler body 4 of the mounting part 10 are pre-attached with grommet members 22 (see Figures 6 and 7). In this case, the packing member 50 shown in Figure 5 is prevented from falling off the locking portion 26 by bringing the retaining piece 26d into contact with the front side surface of the vehicle. Therefore, installation workability is good.

[0029] Then, the engagement portion 26 is inserted into the engagement hole 2a of the upper part 2 of the tailgate, facing forward of the vehicle. As shown in Figure 4, the tips of the pair of engaging portions 26a, 26a of the engaging portion 26 are easily positioned and inserted while deforming toward each other. During insertion, the engaging portion 26 is pushed forward towards the vehicle by the elastic reaction force of the lip portion 40, which has its tip 41 in contact with the seat portion 20. Therefore, the engaging portion 26 can be inserted into the engaging hole 2a before the other clip fixing portions 11 of the mounting portion 10. As shown in Figure 3, when the engagement groove 26c fits into the peripheral edge 2b, the grommet member 22 engages with the engagement hole 2a. This allows the spoiler body 4 to be attached to the upper part 2 of the tailgate in a held position.

[0030] Next, from the direction of arrow A in Figure 2, the worker inserts the tip of the screw 15 diagonally or perpendicularly from the rear to the front of the vehicle through the clamping pieces 23, 24 and the screw holes 27, through holes 28, and insertion holes 20a of the seating surface 20. In this state, as shown in Figure 6, the sealing portions 29 and 30 of the clamping pieces 23 and 24 are spaced apart at a predetermined interval.

[0031] Then, as shown in Figure 3, the spoiler body 4 fastens the grommet member 22 to the seating surface 20 by screwing the screw 15 into the female threaded portion 27a of the screw hole 27. As a result, the distance between the clamping pieces 23 and 24 deforms in a direction that brings them closer together, and the sealing portions 29 and 30 come into contact with the screw 15 in the axial direction and are crushed by the axial force. Furthermore, as shown in Figure 6, the annular seal portion 31 comes into contact with the back side of the head 15a as the screw 15 is screwed in, and is crushed by the axial force as the screwing progresses. In this embodiment, the dimensions are formed such that the screw hole 27 < outer diameter of the screw 15 < through hole 28 in increasing order. Therefore, the through hole 28 allows the screw 15 to be inserted freely. As a result, the screw hole 27 forms a female thread when the screw 15 is threaded into it, while no thread is formed in the through hole 28. As a result, the axial force from tightening the screw 15 causes the clamping piece 23 to deform in a way that pulls it toward the clamping piece 24, reducing the gap and sealing the area around the screw hole 27 and through hole 28 between the clamping pieces 23 and 24 with the sealing portions 29 and 30. In addition, the area around the through hole 28 and the head of the screw 15 are sealed by the sealing portion 31. Therefore, the watertightness between the grommet member 22 and the screw 15 is good.

[0032] First, as shown in Figure 1, the mounting portion 7 of the spoiler body 4, located in the middle portion 6 in the vehicle width direction, is screw-fixed to the upper part 2 of the tailgate by a pair of left and right screw fixing portions 12 located at the outer end 7a in the vehicle width direction. The screw fixing portion 12 is positioned closer to the mounting portion 7 than the clip fixing portion 11. Therefore, the mounting strength near the mounting portion 7 is improved compared to when a clip is used for fixing. Therefore, even when the stop lamp 5 is mounted on the mounting part 7 as a spoiler component having a predetermined weight, the displacement of the spoiler 3 in the vertical direction can be suppressed by external forces acting in the vertical direction. The spoiler body 4 is fixed to the desired mounting strength at the intermediate part 6 in the vehicle width direction by screw fixing at the screw fixing part 12. Furthermore, the area near the seating surface 20 on the spoiler body 4 side is reinforced by the installation of a grommet member 22, and three layers of plate material are stacked from the outside: the front clamping piece 23, the seating surface 20, and the rear clamping piece 24. The three layers of plate material are further fastened with screws 15 to easily obtain the desired mounting strength.

[0033] Even if the rigidity of the front wall portion 4a of the spoiler body 4 cannot be sufficiently set as a single component as in the embodiment, the strength of the periphery of the mounting portion 7 on the center side in the vehicle width direction can be improved. Therefore, this method is suitable for use when a configuration is adopted in which two components are vibration-welded together by injection molding due to molding constraints. Consequently, it is possible to maintain the individual rigidity of the spoiler body 4 while allowing multiple spoiler parts to be combined, thereby improving the degree of freedom in design.

[0034] Furthermore, the number of parts in the clip 14 used in the clip fixing part 11 can be reduced from three or more on the left and right sides to two on each side, improving ease of installation. A pair of screw fixing parts 12 are spaced apart at the outer end 7a in the vehicle width direction of the mounting part 7. Screws 15 are inserted diagonally through the screw fixing parts 12 toward the outside. Therefore, the mounting portion 10 can use the inner space of the mounting portion 7 to insert the screw 15 into the through hole 28. Thus, in this embodiment, the screw fixing portion 12 can be positioned at the outermost part of the outer end 7a of the mounting portion 7 in the vehicle width direction. Therefore, the spoiler body 4 can have a pair of spaced-apart screw fixing parts 12, clip fixing parts 11, 11, and bolt fixing parts 13 spaced approximately equally apart in the vehicle width direction from the inside. In this way, the spoiler body 4 can distribute stress in the vehicle width direction, and further improve mounting strength.

[0035] Furthermore, the spoiler body 4 is screw-fixed to the upper part 2 of the tailgate by the intermediate portion 6 in the vehicle width direction. At this time, the grommet member 22 moves toward the front of the vehicle as it is inserted into the engagement hole 2a due to the elastic reaction force of the lip portion 40. Therefore, even if a clip 14 is pre-installed on the spoiler body 4, the fixing work with screws 15 can be easily performed. In this way, by securing fastening points on the center side in the vehicle width direction, it is possible to improve the ease of installation of the spoiler 3 while ensuring the desired mounting rigidity.

[0036] As described above, the rear vehicle structure of the embodiment, as shown in Figure 1, has a spoiler 3 which includes a spoiler body 4 extending in the vehicle width direction and a stop lamp 5 which is a separate spoiler component from the spoiler body 4. The spoiler 3 is mounted so that its extending direction is aligned with the vehicle width direction of the upper part 2 of the tailgate. The spoiler body 4 includes a mounting section 7 located in the middle section 6 in the vehicle width direction, to which the stop lamp 5 is attached, and a plurality of mounting sections 10 for attaching the spoiler 3 to the upper part 2 of the tailgate. Of these, the multiple mounting parts 10 have a clip fixing part 11 that is fixed using a clip 14 and a screw fixing part 12 that is fixed using a screw 15. Furthermore, the screw fixing portion 12 is positioned closer to the mounting portion 7 than the clip fixing portion 11.

[0037] The vehicle rear structure of this embodiment can improve the ease of installing the spoiler while ensuring the desired mounting rigidity. More specifically, the screw fixing portion 12 on the mounting portion 7 side of the clip fixing portion 11 secures the spoiler body 4 to the upper part 2 of the tailgate of the vehicle 1 using screws 15. The mounting strength near the mounting portion 7 is improved compared to when it is fixed using clips 14. Therefore, even when a stop lamp 5 or the like is attached as a spoiler component with a predetermined weight, displacement is less likely to occur due to external forces acting in the vertical direction. This makes it possible to reduce the number of parts of the clip 14 used in the clip fixing part 11. Consequently, installation workability can be improved.

[0038] Furthermore, the spoiler body 4 is temporarily fixed to the upper part 2 of the tailgate by a screw-fastened intermediate section 6 in the vehicle width direction to prevent it from falling off. This makes it easier to fasten the clip fixing section 11 with the clip 14, thus improving the ease of installation. In this way, by positioning the screw fixing portion 12 on the mounting portion 7 side of the clip fixing portion 11, it is possible to improve the ease of installation of the spoiler 3 while ensuring the desired mounting rigidity.

[0039] As shown in Figure 2, the screw fixing portion 12 is provided at the left and right outer ends 7a of the mounting portion 7 in the vehicle width direction. Therefore, the screw fixing portion 12 provided on the mounting portion 7 is hidden by the stop lamp 5 when the stop lamp 5 is mounted on the mounting portion 7 and is not visible from the outside. This improves the appearance quality. Furthermore, in models where the spoiler body 4 does not exist, a stop lamp 5 with a relatively large width dimension may be installed to improve visibility. Even in such cases, it is possible to set the mounting rigidity to be able to support the weight of spoiler components such as the stop lamp 5, thereby improving versatility. The clip fixing portion 11, screw fixing portion 12, and bolt fixing portion 13 of these mounting portions 10 are provided symmetrically and at approximately equal intervals in the vehicle width direction.

[0040] As shown in Figure 3, the screw fixing portion 12 has a screw 15 inserted diagonally from the inside in the vehicle width direction toward the outside in the vehicle width direction. Therefore, the space formed inside the mounting portion 7 can be effectively utilized as a workspace, improving the ease of installation of the spoiler body 4. As a result, the insertion and fastening of the screws 15 can be easily performed, resulting in good installation efficiency for the spoiler body 4. Furthermore, the angled insertion of the screw 15 allows for efficient increase in resistance to vertical input. This enables increased mounting rigidity of the portion where the stop lamp 5 is mounted near the outer end 7a in the vehicle width direction of the mounting portion 7 where the screw fixing portion 12 is provided.

[0041] The screw fixing portion 12 has a seating surface portion 20 formed on the spoiler body 4, an opening 21 provided adjacent to the seating surface portion 20, and a grommet member 22 that is attached to the seating surface portion 20 through the opening 21. The grommet member 22 has a pair of clamping pieces 23, 24 that clamp the seat surface 20 from the front and rear, and a connecting piece 25 that connects the pair of clamping pieces 23, 24. The grommet member 22 also has a pair of engagement pieces 26a, 26a that protrude forward from the front clamping piece 23 and engage with the upper part 2 of the tailgate. The engaging portion 26 is prevented from deforming toward each other by a screw 15 inserted between the pair of engaging portions 26a, 26a through the pair of clamping pieces 23, 24 and the seating surface portion 20. As a result, the engaging portion 26 cannot be removed from the engaging hole 2a provided in the upper part 2 of the tailgate.

[0042] More specifically, the grommet member 22 is attached to the seating surface 20 formed on the spoiler body 4 through the opening 21. The connecting portion 25 of the grommet member 22 clamps the seating surface 20 from the front and rear, respectively, with the clamping pieces 23 and 24 facing each other, and the axial force of the screw 15 firmly presses the clamping pieces 23 and 24 together. As a result, the annular sealing portions 29, 30 and 31 are crushed, and a watertight seal can be created between the clamping pieces 23 and 24. Furthermore, as shown in Figure 4, tightening the screw 15 expands the space between the pair of engagement parts 26a, 26a, allowing it to engage with the upper part 2 of the tailgate. This allows the spoiler body 4 to be firmly fixed to the upper part 2 of the tailgate. When tightening the screw 15, there is no need to hold the spoiler body 4 with another component such as a temporary holding spring piece, allowing the worker to perform the installation using both hands. In this case, as shown in Figure 3, a boss portion may be provided protruding from the opposing surfaces between the clamping pieces 23 and 24, and at least a portion of it may be inserted into the insertion hole 20a of the seating surface 20 to lock it in place. This holds the grommet member 22 to the seating surface 20 which is formed by bulging out from the front wall of the spoiler body 4, preventing it from falling off during installation. As a result, the grommet member 22 can be temporarily fixed to the seating surface 20, making it easier to insert the screw 15. Therefore, the ease of installation is further improved.

[0043] Furthermore, a pair of upper and lower engaging portions 26a, 26a each have engaging grooves 26c formed therein. The engaging portions 26a, 26a, which engage with the peripheral portion 2b at two points, upper and lower, are prevented from deforming and cannot be released by the inserted screw 15. Furthermore, if the screw 15 is partially inserted into the engagement hole 2a or in a semi-fitted state, the tip of the screw 15 cannot be inserted between the pair of engagement parts 26a, 26a. Therefore, the engagement groove 26c can be securely engaged and fixed in the engagement hole 2a, preventing situations where the screw fixing work is completed in a semi-fitted state. Therefore, the engaging portion 26 can be further firmly engaged with the engaging hole 2a to prevent it from falling out. The seat portion 20 is then clamped from the front and back by a pair of clamping pieces 23 and 24, creating a structure where three layers of plate material overlap, which reinforces the seat and increases its mounting rigidity.

[0044] Furthermore, the screw 15 fastens the three layers of seating surface 20 and the clamping pieces 23 and 24 in an out-of-plane direction and is interposed between the upper and lower pair of engaging portions 26a, 26a. As a result, the mounting rigidity of the engaging portion 26 is increased compared to the case where it is provided on the single layer of seating surface 20. For this reason, injection molding may be used due to molding constraints. For example, in some cases, the spoiler body 4 is made up of two separate upper and lower parts. When each part of the spoiler body 4 is injection molded, it may be difficult to set the plate thickness to be thicker compared to the thickness dimension obtained by blow molding. Even in such cases, by attaching a grommet member 22 to the seating surface 20, it is possible to set the strength around the seating surface 20 to be equivalent to or greater than that when the thickness dimension around the seating surface 20 is large. Therefore, the mounting rigidity of the screw fixing part 12 can be increased to further prevent the spoiler body 4 from displacing in the vertical direction.

[0045] The clamping pieces 23 and 24 have screw holes 27 and through holes 28 into which the screws 15 are inserted, and annular sealing portions 29, 30, and 31 protruding around each screw hole 27 and through hole 28. Therefore, the annular sealing portion 31 is provided on the rear surface 24a of the rear clamping piece 24 and contacts the head 15a of the screw 15. Furthermore, the annular sealing portions 29-31 protruding around the screw holes 27 and through holes 28 deform and collapse when pressed against opposing portions, sealing the screw holes 27 and through holes 28 in an annular shape. Therefore, no separate sealing members are required for watertight sealing, reducing the number of parts and further improving ease of installation.

[0046] The annular sealing portion 31 deforms by being crushed between the rear surface of the rear clamping piece 24 and the head of the screw 15, surrounding the through hole 28 and creating an annular seal. Therefore, sealing can be achieved simply by screwing in the screw 15. Consequently, installation workability is further improved.

[0047] The annular sealing portions 29 and 30 are provided on at least one of the opposing surfaces of the pair of clamping pieces 23 and 24, and abut against the other of the pair of clamping pieces 23 and 24. As a result, the sealing portions 29 and 30 surround the screw hole 27 and through hole 28, creating an annular seal. Therefore, sealing can be achieved, for example, simply by screwing in the screw 15 to bring the pair of clamping pieces 23 and 24 closer together. Consequently, installation workability is further improved.

[0048] Furthermore, each of the pair of engaging portions 26a, 26a (see Figure 5) has a recessed engaging groove 26c, 26c on its outer surface 26e that engages with the peripheral edge 2b of the engaging hole 2a. Then, the outer surface 26e of the engaging portion 26a engages the peripheral edge 2b of the engaging hole 2a with the recessed engaging groove 26c. As a result, the engaging portion 26 can be more firmly engaged with the engaging hole 2a, preventing it from being pulled out, thereby improving mounting rigidity.

[0049] As shown in Figure 4, the clamping piece 23 located on the front side of the grommet member 22 has an elastically deformable lip portion 40 projecting outward from at least one outer end face. The tip 41 of the lip portion 40 is elastically brought into contact with the periphery of the insertion hole 20a shown in Figure 3, which is formed in the seating surface portion 20, from the front of the vehicle. Therefore, the grommet member 22 moves toward the front of the vehicle as it is inserted into the engagement hole 2a due to the elastic reaction force of the lip portion 40. Consequently, the fixing operation can be performed even more easily.

[0050] As shown in Figure 5, a packing member 50 is provided that is sandwiched and seals between the upper part 2 of the tailgate and the front clamping piece 23. Therefore, when the spoiler body 4 is attached to the upper part 2 of the tailgate, the packing member 50 is sandwiched between the upper part 2 of the tailgate and the front clamping piece 23. As a result, the area around the engagement hole 2a on the vehicle body side and the grommet member 22 are sealed by the compressed packing member 50.

[0051] As shown in Figure 6, the engaging portion 26 has elastically deformable retaining pieces 26d integrally protruding from the outer surfaces 26e shown by the upper and lower engaging portions 26a (see Figure 7). As shown in Figure 7, the retaining piece 26d abuts against the front side surface of the vehicle of the packing member 50 that is mounted in the engagement grooves 26c, 26c, and holds it in place so that it does not fall off the engagement portion 26. This further improves the installation process. Thus, the screw fixing portion 12 of the vehicle rear structure in this embodiment is positioned closer to the mounting portion 7 than the clip fixing portion 11. This allows the screw fixing portion 12 to improve the ease of installing the spoiler while ensuring the desired mounting rigidity, thus providing practically beneficial effects.

[0052] The present invention is not limited to the embodiments described above, and various modifications are possible. The embodiments described above are illustrative examples provided to facilitate understanding of the present invention, and are not necessarily limited to those comprising all the configurations described. Furthermore, it is possible to replace parts of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add configurations from other embodiments to the configuration of one embodiment. In addition, it is possible to delete parts of the configuration of each embodiment, or to add or replace other configurations. Possible modifications to the above embodiments are, for example, as follows.

[0053] In the embodiments described, a screw fixing portion 12 has been shown in which a seating surface portion 15 formed on the outer end 7a of the mounting portion 7 in the vehicle width direction is sandwiched by a grommet member 22. However, the structure is not limited to a combination of a grommet with a pre-formed female thread and a male thread that screws into it. For example, the female thread does not need to be formed in advance, and the female thread may be formed by screwing in the screw 15. Also, the screw fixing portion 12 may be positioned near the outer end of the mounting portion 7 in the vehicle width direction. Furthermore, the shapes of the seating surface portion 15 and the grommet member 22 may be other shapes. Furthermore, screws of other shapes, such as tapping screws, may be used as screw 15. In this case, since the tapping screw forms an internal thread in the through hole, there is no need to form an internal thread portion in the through hole. In other words, the screw fixing portion 12, which is fixed using a screw 15, can be positioned at any location as long as it is located on the mounting portion 7 side of the clip fixing portion 11. Also, in this embodiment, the screw 15 is inserted and tightened at a predetermined angle of inclination α, but it is not limited to this, and the screw 15 may be inserted and tightened in a direction perpendicular to the surface. Thus, the shape, number, arrangement, and material of the screw fixing portion 12 are not particularly limited to the vehicle rear structure of this embodiment.

[0054] Furthermore, in this embodiment, as shown in Figure 4, the pair of upper and lower engaging portions 26a, 26a are formed in a tapered shape, with the width dimension narrowing towards the tip (see Figure 5). In addition, each engaging portion 26a has an engaging groove 26c and a retaining piece 26d formed on its upper and lower outer surface 26e, respectively. However, this is not the only embodiment. That is, the shape, number, arrangement, and material of the engaging portions 26a, engaging grooves 26c, and retaining pieces 26d are not particularly limited to the vehicle rear structure of this embodiment.
