Description

[Technical Field]

[0001] The present disclosure relates to a clip mounting seat and a vehicle component. [Background technology]

[0002] A resin molded product, such as a spoiler, that is attached to the body of an automobile is provided with a plurality of clip mounting seats. A clip is attached to each clip mounting seat. The resin molded product is attached to the vehicle body by inserting the clip attached to the clip mounting seat into a mounting hole or the like formed in the vehicle body.

[0003] An example of a clip mounting seat is disclosed in Patent Document 1. The clip mounting seat disclosed in Patent Document 1 has a clip locking hole and a guide groove in a clip seating portion on a partially open peripheral wall. The guide groove extends from the clip locking hole toward the open end. The clip has a seat fitting portion in which a pair of flanges are integrally formed via a neck portion, and the neck portion is inserted into the guide groove to fit into the clip locking hole.

[0004] The clip mounting seat has protrusions protruding outward on the left and right front sides of the guide groove. The protrusions form steps that are stepped relative to the surface of the clip mounting seat surrounding the clip locking hole to which the clip is attached. When the clip mounted on the clip mounting seat comes into contact with one of the flanges, the step prevents the clip from slipping out of the clip locking hole and falling off the clip mounting seat.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-192918 Summary of the Invention [Problem to be solved by the invention]

[0006] In the clip mounting seat described in Patent Document 1, the portion where the step that functions as a clip retainer is provided is relatively thick. Therefore, when the neck of the clip is inserted into the guide groove and fitted into the clip locking hole, the seat fitting portion and the step interfere strongly as the neck of the clip passes through the step. This requires a large force to fit the clip into the clip locking hole, making it difficult to mount the clip on the clip mounting seat.

[0007] An object of the present disclosure is to prevent a clip from falling off from a clip mounting seat and to make it easier to mount a clip on the clip mounting seat. [Means for solving the problem]

[0008] In order to achieve the above object, the technique of the present disclosure has devised a configuration for the mounting plate portion on which the clip is mounted so that the thickness of the portion of the clip mounting seat where the step portion is provided is reduced.

[0009] Specifically, a first aspect of the present disclosure is directed to a clip mounting seat to which a clip is attached, the clip having a seat fitting portion formed by a pair of flange-shaped portions integrally formed via a neck portion. The clip mounting seat of the first aspect includes a mounting plate portion to which the clip is attached. The mounting plate portion is formed with a clip fitting hole having an insertion opening open to the outer periphery. The mounting plate portion has a seat portion to which the clip is attached by inserting the neck portion through the insertion opening and fitting the seat fitting portion into the clip fitting hole, and an insertion side portion that constitutes a portion closer to the insertion opening than the seat portion. The insertion side portion has a first surface located on one side in the thickness direction and a second surface located on the other side in the thickness direction. The first surface has an inclined surface that is inclined toward the second surface as it approaches the insertion opening relative to the surface on the same side of the seat portion in the thickness direction. A step portion that interferes with the flange portion in the direction in which the clip attached to the seating portion is removed from the clip fitting hole is provided in a portion of the second surface that corresponds to the midpoint of the inclined surface.

[0010] In a second aspect of the present disclosure, in the clip mounting seat of the first aspect, when the thickness in the plane normal direction of the inclined surface between the first surface and the tip of the stepped portion among the insertion side portions is Td and the distance between the pair of flange portions is Dc, the thickness Td and the distance Dc satisfy the relationship Td < Dc, and it is a clip mounting seat.

[0011] A third aspect of the present disclosure is a clip mounting seat in which a relief surface parallel to the inclined surface is formed at the tip of the stepped portion in the clip mounting seat of the first aspect.

[0012] A fourth aspect of the present disclosure targets vehicle parts. The vehicle parts of the fourth aspect include a resin molded product provided with any one of the clip mounting seats of the first to third aspects.

Advantages of the Invention

[0013] According to the first aspect, the first surface located on one side in the thickness direction of the insertion side portion is formed as an inclined surface. And on the second surface located on the other side in the thickness direction of the insertion side portion, a stepped portion that interferes with the flange portion of the clip attached to the seating portion is provided. The clip attached to such a clip mounting seat is prevented from coming out of the clip fitting hole and falling off the clip mounting seat by the contact of one flange portion with the stepped portion. The clip is attached to the seating portion by inserting the neck portion through the insertion port and fitting it into the clip fitting hole in a state where the clip is inclined obliquely along the inclination of the first surface with respect to the clip mounting seat. The thickness of the portion provided with the stepped portion of the insertion side portion becomes thin because the first surface is formed as an inclined surface. Thus, in the process of attaching the clip to the clip mounting seat, when the neck portion of the clip passes through the stepped portion, the interference strength between the seat fitting portion and the stepped portion can be reduced. Thereby, the force required to fit the clip into the clip fitting hole can be reduced, and it becomes easier to attach the clip to the clip mounting seat.

[0014] According to the second aspect, the thickness Td between the inclined surface of the insertion side portion and the tip of the step portion is smaller than the distance Dc between the pair of flanges of the clip. This is advantageous in reducing the strength of interference between the seat fitting portion and the step portion during the process of attaching the clip to the clip attachment seat. This makes it easier to attach the clip to the clip attachment seat.

[0015] According to the third aspect, a relief surface is formed at the tip of the step. The relief surface is a surface parallel to the inclined surface on the first surface of the insertion side portion. This relief surface prevents a sharp corner from being formed at the tip of the step. Furthermore, during the process of attaching the clip to the clip mounting seat, the inclined surface on the first surface guides one of the flange-shaped portions of the clip, while the relief surface of the step guides the other flange-shaped portion of the clip. Therefore, excessive interference between the seat fitting portion and the step can be avoided, and attachment of the clip to the clip mounting seat can be made even easier.

[0016] According to a fourth aspect, a resin molded product is provided with the clip mounting seat of any one of the first to third aspects. The clip mounting seat prevents the clip from falling off and makes it easy to mount the clip. This allows for efficient mounting of the vehicle part to an object, and makes it difficult for the clip to unintentionally come off the clip mounting seat before the vehicle part is mounted to the object.

[0018] Exemplary embodiments will be described in detail below with reference to the drawings. In the following embodiments, a clip mounting base according to the present disclosure will be described using an example in which it is applied to a rear spoiler. Note that the drawings are intended to conceptually explain the technology of the present disclosure. Therefore, in the drawings, dimensions, ratios, or numbers may be exaggerated or simplified to facilitate understanding of the technology of the present disclosure.

[0019] First Embodiment The clip mounting base 10 of this embodiment 1 is provided on a rear spoiler 1 shown in FIG. 1. The rear spoiler 1 is an example of a vehicle part. The rear spoiler 1 is an aerodynamic part attached to the rear of a vehicle. For example, the rear spoiler 1 is disposed above the back door of a hatchback vehicle. The rear spoiler 1 protrudes rearward from the vehicle body and is provided above the rear window in a canopy-like shape.

[0020] <Rear spoiler> The rear spoiler 1 includes an upper panel 3 and a lower panel 5. The upper panel 3 is a resin panel that forms the upper surface of the rear spoiler 1. The lower panel 5 is a resin panel that forms the lower surface of the rear spoiler 1. The lower panel 5 is an example of a resin molded product. The outer peripheral portions of the upper panel 3 and the lower panel 5 are bonded together using an adhesive. This allows the upper panel 3 and the lower panel 5 to be joined together.

[0021] The rear portion of the rear spoiler 1 on the vehicle body rear side has a hollow structure, and has an internal space S1 defined by the upper panel 3 and the lower panel 5. The lower panel 5 has a recessed portion 7 that is open toward the upper panel 3. The recessed portion 7 defines the internal space S1 between itself and the upper panel 3. A lamp opening 8 is formed in a rear wall 7a located on the rear side of the recessed portion 7 on the vehicle body rear side. A high-mounted stop lamp 9 is housed in the internal space S1 of the rear spoiler 1 so that it can be illuminated rearward from the lamp opening 8.

[0022] A plurality of clip mounting seats 10 are integrally formed on the lower panel 5. The clip mounting seats 10 are located near the front end of the lower panel 5 in the longitudinal direction of the vehicle body, and are arranged at positions spaced apart from one another in the vehicle width direction (left-right direction) (positions indicated by dashed cross marks in Figure 1). A clip 50 is attached to each clip mounting seat 10. The clip 50 attached to each clip mounting seat 10 is then attached to the vehicle body, which is the mounting target. The rear spoiler 1 is attached to the vehicle body panel using the clips 50.

[0023] <clip> The clip 50 shown in FIG. 4 is a fastener also known as a fastener. The clip 50 is a resin component made of polyacetal (POM) or the like, and is formed, for example, by injection molding. The clip 50 has a seat fitting portion 51 and an anchor portion 57. The seat fitting portion 51 is a portion that fits into the clip mounting base 10, and is formed by a pair of flange-shaped portions 53 that are integrally formed via a neck portion 55. Each of the pair of flange-shaped portions 53 is a disk-shaped portion that protrudes toward the outer periphery of the neck portion 55.

[0024] One of the flanges 53 constitutes a first flange 53a that forms one end of the clip 50 in the longitudinal direction. The other flange 53 constitutes a second flange 53b that is located midway in the longitudinal direction of the clip. The second flange 53b protrudes from the neck 55 by a longer length than the first flange 53a protrudes from the neck 55. An anchor 57 is provided on the second flange 53b. The anchor 57 is inserted into an attachment hole formed in the vehicle body panel to be fastened to the vehicle body panel.

[0025] <Clip mounting base> 2 and 3, each clip mounting seat 10 is formed in a box shape with one side partially open so as to protrude from the front side of the lower panel 5 (i.e., the rear side of the rear spoiler 1). The clip mounting seats 10 are made of the same material as the lower panel main body 5a. Examples of materials for the lower panel main body 5a include acrylonitrile butadiene styrene (ABS), polypropylene (PP), and composite resin materials of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS).

[0026] The clip mounting base 10 includes a leg portion 11 and a mounting plate portion 15. The leg portion 11 is configured with a rectangular frame-shaped wall portion. Specifically, the leg portion 11 is integrally formed with a pair of side walls 11a, a rear wall portion 11b, and a front wall portion 11c.

[0027] The pair of side walls 11a are walls located on both sides in a direction perpendicular to the mounting direction Di (hereinafter referred to as the "clip mounting direction") Di during the installation work of the clip 50. The height of the rear portion of each side wall 11a in the clip mounting direction Di is lower than the height of the front portion of the side wall 11a in the clip mounting direction Di. The height of the front portion of each side wall 11a decreases toward the front in the clip mounting direction Di. The front end of each side wall 11a in the clip mounting direction Di is formed by a base end portion on the lower panel main body 5a side.

[0028] The rear wall portion 11b is a wall portion located on the rear side in the clip attachment direction Di, and connects the rear ends of the pair of side wall portions 11a in the clip attachment direction Di. The front wall portion 11c is a wall portion located on the front side in the clip attachment direction Di, and connects the front ends of the pair of side wall portions 11a in the clip attachment direction Di. The height of the front wall portion 11c is lower than the height of the rear wall portion 11a. The front ends of each side wall portion 11a, the front wall portion 11c, and the attachment plate portion 15 form an insertion opening 13 into which the clip 50 is inserted.

[0029] The mounting plate 15 is the portion to which the clip 50 is attached, and is formed integrally with the tip of the leg 11. The outer periphery of the mounting plate 15 is connected to the top of each side wall 11a and the top of the rear wall 11a. The mounting plate 15, together with the leg 11, surrounds the mounting space S2. The mounting space S2 is a space used to attach the clip 50, and is open to the back side of the lower panel 5 corresponding to the mounting plate 15. A clip fitting hole 17 is formed in the mounting plate 15. The clip fitting hole 17 has an insertion opening 19 that opens to the outer periphery of the mounting plate 15. The insertion opening 19 opens to the front side in the clip attachment direction Di, and is formed as an opening integral with the insertion opening 13.

[0030] The attachment plate 15 has a seating portion 21 and an insertion side portion 23. The seating portion 21 is the portion where the clip 50 is attached by inserting the neck portion 55 through the insertion opening 19 and fitting the seat fitting portion 51 into the clip fitting hole 17, and constitutes the rear portion of the attachment plate 15 in the clip attachment direction Di. The rear end of the clip fitting hole 17 is located at the seating portion 21. The insertion side portion 23 is the portion that slides in the process of attaching the clip 50 to the seating portion 21, and constitutes the portion closer to the insertion opening 19 than the seating portion 21.

[0031] The seating portion 21 and the insertion side portion 23 each have a front surface 21a, 23a and a back surface 21b, 23b. Here, the front surfaces 21a, 23a are surfaces facing the front side of the clip mounting seat 10 (i.e., the back side of the rear spoiler 1). The back surfaces 21b, 23b are surfaces facing the back side of the clip mounting seat 10 (i.e., the front side of the rear spoiler 1). In this example, the front surface 23a of the insertion side portion 23 corresponds to a first surface located on one side in the thickness direction. In this example, the back surface 23b of the insertion side portion 23 corresponds to a second surface located on the other side in the thickness direction.

[0032] Both the front surface 21a and the back surface 21b of the seating portion 21 extend in a direction perpendicular to the thickness direction of the seating portion 21. In other words, the thickness of the seating portion 21 is constant. On the other hand, the front surface 23a of the insertion side portion 23 has an inclined surface 25 that is inclined so as to approach the back surface 23b toward the insertion opening 19 relative to the surface on the same side in the thickness direction of the seating portion 21, i.e., the front surface 23a of the insertion side portion 23. In this example, the front surface 23a of the insertion side portion 23 is the inclined surface 25 over its entirety. The inclination angle of the inclined surface 25 is, for example, 5° to 15°. The back surface 23b of the insertion side portion 23 has a surface on the same side in the thickness direction of the seating portion 21, i.e., a surface that extends in the same direction as the back surface 21b of the seating portion 21.

[0033] On the back surface 23b of the insertion side portion 23, a pair of convex portions 27 are provided. The pair of convex portions 27 are formed so as to project to the back side of the insertion side portion 23 separately on both sides of the clip fitting hole 17 in the back surface 23b of the insertion side portion 23. Each convex portion 27 is located on the insertion port 19 side and constitutes a portion of the insertion side portion 23 on the insertion port 19 side. Each convex portion 27 is not provided in the back side portion in the clip mounting direction Di of the insertion side portion 23. The front end surface of each convex portion 27 in the clip mounting direction Di constitutes the fitting port 13.

[0034] The back end surface of each convex portion 27 in the clip mounting direction Di forms a step with the back surface of the insertion side portion 23 other than the convex portion. The back end surface of each convex portion 27 and the back surface of the convex portion 27 form a stepped portion 29. The stepped portion 29 is provided at a portion corresponding to the middle portion of the inclined surface 25 in the back surface 23b of the insertion side portion 23. The stepped portion 29 functions as a retaining means by interfering with the first flange portion 53a in the removal direction De from the clip fitting hole 17 of the clip 50 attached to the seating portion 21.

[0035] When the distance in the thickness direction of the seating portion 21 (hereinafter referred to as "distance between both surfaces of the mounting plate portion") between the surface 21a of the seating portion 21 in the mounting plate portion 15 and the back surface 23b of the convex portion 27 is Tm, and the interval between the pair of flange portions 53 in the clip 50 is Dc, the interval Dc of the flange portion 53 and the distance Tm between both surfaces of the mounting plate portion 15 satisfy the relationship Dc < Tm. When the surface of the insertion side portion 23 does not have the inclined surface 25, the thickness of the portion corresponding to the stepped portion 29 in the insertion side portion 23 is the same as the distance Tm between both surfaces of the mounting plate portion 15. In this case, in the process of fitting the clip 50 into the clip fitting hole 17, the seat fitting portion 51 and the stepped portion 29 strongly interfere with each other.

[0036] Furthermore, when the thickness in the plane normal direction of the inclined surface 25 between the surface 23a and the tip of the stepped portion 29 in the insertion side portion 23 (hereinafter referred to as the "thickness at the stepped portion") is Td, the thickness Td at the stepped portion and the interval Dc of the flange portion 53 satisfy the relationship Td < Dc. If the thickness Td at the stepped portion is greater than the interval Dc of the flange portion 53, as described above, in the process of fitting the clip 50 into the clip fitting hole 17, the seat fitting portion 51 and the stepped portion 29 will strongly interfere with each other. Therefore, satisfying the above relationship (Td < Dc) is important for reducing the strength of interference between the seat fitting portion 51 and the stepped portion 29.

[0037] Also, when the thickness of the seating portion 21 is Ts, the interval Dc of the flange portion 53 and the thickness Ts of the seating portion 21 satisfy the relationship Dc ≒ Ts. That is, the interval Dc of the flange portion 53 and the thickness Ts of the seating portion 21 are substantially equal to each other. Here, "substantially equal" means that the interval Dc of the flange portion 53 is in the range of 0 mm to 0.2 mm with respect to the thickness Ts of the seating portion 21. The interval Dc of the flange portion 53 is greater than the thickness Ts of the seating portion 21. By satisfying the above relationship (Dc ≒ Ts), the looseness of the clip in the state attached to the seating portion 21 can be reduced.

[0038] The clip mounting seat 10 with the above configuration is designed such that the insertion force of the clip 50 is 35 N or less and the holding force of the clip 50 is 20 N or more. Here, the "insertion force of the clip 50" is the maximum load applied to the clip 50 in the clip mounting direction Di until the clip 50 is mounted on the clip mounting seat 10. When the insertion force of the clip 50 is 35 N or less, it is possible for the operator to continuously perform the mounting operation of the clip 50 without feeling uncomfortable. Also, the "holding force of the clip 50" is the maximum load applied to the clip 50 in the removal direction De by pressing the clip 50 from the mounted state until the clip 50 comes off the clip mounting seat 10. When the holding force of the clip 50 is 20 N or more, it is possible to ensure the reaction force necessary to prevent the clip 50 from falling off the clip mounting seat 10 during handling between processes after the clip 50 is mounted or during transportation.

[0039] <How to attach the clip> 6, to attach the clip 50 to the clip mounting seat 10, the clip 50 is placed in an inclined position so that the second flange portion 53b is parallel to the inclined surface 25 of the insertion side portion 23, and in this state, the first flange portion 53a of the clip 50 is fitted into the fitting opening 13, while the neck portion 55 is inserted from the insertion opening 19 into the clip fitting hole 17 with the second flange portion 53b aligned with the inclined surface 25. The clip 50 is then slid toward the back of the clip fitting hole 17 until the seat fitting portion 51 reaches the seat portion 21, and attached to the mounting plate portion 15.

[0040] 7, in the process of sliding the clip 50 toward the back of the clip fitting hole 17, the neck portion 55 moves from the insertion side portion 23 to the seating portion 21, and the posture of the clip 50 is changed from an inclined posture to a posture in which the second flange portion 53b approaches a posture parallel to the surface of the seating portion 21. At this time, the first flange portion 53a and the second flange portion 53b of the clip 50 are slightly elastically deformed, and the first flange portion 53a moves over the step portion 29 of the insertion side portion 23. The first flange portion 53a and the second flange portion 53b elastically return to their original position after the first flange portion 53a moves over the step portion 29. As shown in Figure 8, when the seat fitting portion 51 of the clip 50 is completely fitted into the clip fitting hole 17, the first flange portion 53a and the second flange portion 53b of the clip 50 are positioned parallel to the back surface 21b and the front surface 21a of the seating portion 21, respectively, and the seating portion 21 is sandwiched between the first flange portion 53a and the second flange portion 53b.

[0041] In this way, the clip 50 is attached to the clip mounting seat 10. When attached to the clip mounting seat 10, the clip 50 will not tilt so that the second flange portion 53b is parallel to the inclined surface 25 of the insertion side portion 23 unless an external force is applied to tilt the clip 50. When the clip 50 attempts to slide in the removal direction De out of the clip fitting hole 17, the first flange portion 53a of the clip 50 interferes with the step portion 29 of the insertion side portion 23. This makes it difficult for the clip 50 to come off the clip mounting seat 10, for example, during transportation of the rear spoiler 1 before installation on the vehicle body.

[0042] -Features of the first embodiment- In the clip mounting seat 10 of this embodiment 1, the surface of the insertion side portion 23 is formed into an inclined surface 25. A step portion 29 is provided on the back surface of the insertion side portion 23, which interferes with the first flange portion 53a of the clip 50 mounted on the seating portion 21. The clip 50 mounted on such a clip mounting seat 10 is prevented from slipping out of the clip fitting hole 17 and falling off the clip mounting seat 10 by the first flange portion 53a coming into contact with the step portion 29. The clip 50 is mounted on the seating portion 21 by inserting the neck portion 55 into the clip fitting hole 17 through the insertion opening 19 while tilted obliquely relative to the clip mounting seat 10 so as to follow the inclined surface 25 of the insertion side portion 23. The thickness of the portion of the insertion side portion 23 where the step portion 29 is provided is reduced by forming the surface into the inclined surface 25. This reduces the strength of interference between seat fitting portion 51 and step portion 29 when neck portion 55 of clip 50 passes through step portion 29 in the process of attaching clip 50 to clip mounting seat 10. This reduces the force required to fit clip 50 into clip fitting hole 17, making it easier to attach clip 50 to clip mounting seat 10.

[0043] In the clip mounting seat 10 of this embodiment 1, the thickness Td of the step portion between the inclined surface 25 of the insertion side portion 23 and the tip of the step portion 29 is smaller than the distance Dc between the pair of flange-shaped portions 53 of the clip 50. This is advantageous in reducing the strength of interference between the seat fitting portion 51 and the step portion 29 during the process of mounting the clip 50 to the clip mounting seat 10. Therefore, the effect of making it easier to mount the clip 50 on the clip mounting seat 10 can be preferably obtained.

[0044] The rear spoiler 1 of this embodiment 1 includes a lower panel 5 provided with a clip mounting seat 10. The clip mounting seat 10 prevents the clip 50 from falling off and also makes it easy to mount the clip 50. This allows the work of mounting the rear spoiler 1 to the vehicle body panel to which it is to be mounted to be performed efficiently, and makes it difficult for the clip 50 to unintentionally come off the clip mounting seat 10 before the rear spoiler 1 is mounted to the vehicle body panel.

[0045] Second Embodiment The clip mounting seat 10 of this embodiment 2 differs from that of the above-described embodiment 1 in the configuration of the insertion side portion 23. In this embodiment 2, the rear spoiler 1 and the clip mounting seat 10 are configured in the same manner as in the above-described embodiment 1, except for the configuration of the insertion side portion 23 of the clip mounting seat 10 which differs from that of the above-described embodiment 1. Therefore, the configuration of the clip mounting seat 10 that differs from that of the above-described embodiment 1 will be described, and detailed description of matters related to the same configuration will be omitted.

[0046] 9, in the clip mounting seat 10 of this second embodiment, an inclined surface 25 is formed on the back surface of the insertion side portion 23, and a step portion 29 is provided on the front surface of the insertion side portion 23. The back surface 23b of the insertion side portion 23 in this example corresponds to the first surface located on one side in the thickness direction. The front surface 23a of the insertion side portion 23 in this example corresponds to the second surface located on the other side in the thickness direction.

[0047] More specifically, the back surface 23b of the insertion side portion 23 has an inclined surface 25 that is inclined so as to approach the front surface toward the insertion opening 19 relative to the back surface 21b of the seating portion 21, that is, the surface on the same side in the thickness direction of the seating portion 21. In this example, the entire back surface 23b of the insertion side portion 23 is inclined surface 25. The inclination angle α2 of the inclined surface 25 is, for example, 5° to 15°. The front surface 23a of the insertion side portion 23 has a surface on the same side in the thickness direction of the seating portion 21, that is, a surface that extends in the same direction as the front surface 21a of the seating portion 21.

[0048] On the surface 23a of the insertion side portion 23, a pair of convex portions 27 are provided. The pair of convex portions 27 are formed so as to project on both sides of the clip fitting hole 17 on the surface of the insertion side portion 23. Each convex portion 27 is located on the insertion port 19 side and constitutes a portion of the insertion side portion 23 on the insertion port 19 side. Each convex portion 27 is not provided on the back side portion in the clip mounting direction Di of the insertion side portion 23. The front end surface of each convex portion 27 in the clip mounting direction Di constitutes the fitting port 13.

[0049] The back end surface of each convex portion 27 in the clip mounting direction Di forms a step with the surface 23a of the insertion side portion 23 other than the convex portion 27. The back end surface of each convex portion 27 and the back surface of the convex portion 27 form a stepped portion 29. The stepped portion 29 is provided at a portion corresponding to the middle portion of the inclined surface 25 in the surface 23a of the insertion side portion 23. The stepped portion 29 functions as a retaining means by interfering with the second flange portion 53b in the removal direction De from the clip fitting hole 17 of the clip 50 attached to the seating portion 21.

[0050] Also in the clip mounting seat 10 of this example, similar to the first embodiment, when the distance between the pair of flange portions 53 in the clip 50 is Dc, the double-sided distance of the mounting plate portion is Tm, the thickness of the stepped portion is Td, and the thickness of the seating portion 21 is Ts, the distance Dc between the flange portions 53 and the double-sided distance Tm of the mounting plate portion 15 satisfy the relationship Dc < Tm. Also, the thickness Td of the stepped portion and the distance Dc between the flange portions 53 satisfy the relationship Td < Dc. And the distance Dc between the flange portions 53 and the thickness Ts of the seating portion 21 satisfy the relationship Dc ≒ Ts.

[0051] <Method of attaching the clip> 10 , to attach the clip 50 to the clip attachment seat 10 having the above-described configuration, the clip 50 is placed in an inclined position so that the first flange portion 53a is parallel to the inclined surface 25 of the insertion side portion 23, and in this state, the first flange portion 53a of the clip 50 is fitted into the fitting opening 13, while the neck portion 55 is inserted from the insertion opening 19 into the clip fitting hole 17 with the first flange portion 53a aligned with the inclined surface 25. The clip 50 is then slid toward the back of the clip fitting hole 17 until the seat fitting portion 51 reaches the seat portion 21, and attached to the attachment plate portion 15.

[0052] 11 , in the process of sliding the clip 50 toward the back of the clip fitting hole 17, the neck portion 55 moves from the insertion side portion 23 to the seating portion 21, and the posture of the clip 50 is changed from an inclined posture to a posture in which the first flange portion 53a approaches a posture parallel to the rear surface of the seating portion 21. At this time, the second flange portion 53b and the first flange portion 53a of the clip 50 are slightly elastically deformed, and the second flange portion 53b climbs over the step portion 29 of the insertion side portion 23. The second flange portion 53b and the first flange portion 53a elastically return to their original position after the second flange portion 53b climbs over the step portion 29. As shown in Figure 12, when the seat fitting portion 51 of the clip 50 is completely fitted into the clip fitting hole 17, the first flange portion 53a and the second flange portion 53b of the clip 50 are positioned parallel to the back surface 21b and the front surface 21a of the seating portion 21, respectively, and the seating portion 21 is sandwiched between the first flange portion 53a and the second flange portion 53b.

[0053] In this way, the clip 50 is attached to the clip mounting seat 10. When attached to the clip mounting seat 10, the clip 50 does not tilt so that the first flange portion 53a becomes parallel to the inclined surface 25 of the insertion side portion 23 unless an external force is applied to tilt the clip 50. When the clip 50 attempts to slide in the removal direction De out of the clip fitting hole 17, the second flange portion 53b of the clip 50 interferes with the step portion 29 of the insertion side portion 23. This makes it difficult for the clip 50 to come off the clip mounting seat 10, for example, during transportation of the rear spoiler 1 before installation on the vehicle body.

[0054] -Features of the second embodiment- In the clip mounting seat 10 of this embodiment 2, the back surface of the insertion side portion 23 is formed as an inclined surface 25. A step portion 29 is provided on the surface of the insertion side portion 23, which interferes with the second flange portion 53b of the clip 50 attached to the seat portion 21. With this configuration, as in the first embodiment, the step portion 29 of the clip mounting seat 10 prevents the clip 50 from falling off by preventing it from coming off, and the strength of interference between the seat fitting portion 51 of the clip 50 and the step portion 29 is reduced, making it easier to attach the clip 50. In addition, the same effects as in the first embodiment can be obtained in other respects.

[0055] <<Variation>> As shown in Fig. 13, this modified example is an example in which the shape of the step portion 29 of the clip mounting seat 10 of the first embodiment is modified. In the clip mounting seat 10 of this example, a relief surface 31 is formed at the tip of the step portion 29. The relief surface 31 is a chamfered portion that serves to guide the first flange portion 53a while avoiding excessive interference between the step portion 29 and the first flange portion 53a during the process of mounting the clip 50 to the clip mounting seat 10. The relief surface 31 is formed as a surface parallel to the inclined surface 25 of the insertion side portion 23.

[0056] When the inclination angle of inclined surface 25 relative to surface 21a of seating portion 21 is α and the inclination angle of relief surface 31 relative to back surface 21b of protrusion 27 parallel to surface 21a of seating portion 21 is β, inclination angle α of inclined surface 25 and inclination angle β of relief surface 31 satisfy the relationship α=β. In other words, inclination angle α of inclined surface 25 and inclination angle β of relief surface 31 are equal to each other. Here, "equal" does not mean that they are strictly identical, and there may be an angle difference within the range of manufacturing tolerances.

[0057] According to the clip mounting seat 10 of this modified example, a relief surface 31 is formed at the tip of the step portion 29, thereby eliminating a sharp corner at the tip of the step portion 29. Furthermore, as shown in Fig. 14, in the process of mounting a clip 50 to the clip mounting seat 10, the inclined surface 25 of the insertion side portion 23 guides the second flange portion 53b of the clip 50, and the relief surface 31 of the step portion 29 also guides the first flange portion 53a of the clip 50. Therefore, excessive interference between the seat fitting portion 51 and the step portion 29 can be avoided, and mounting the clip 50 to the clip mounting seat 10 can be made even easier.

[0058] Other Embodiments In the above-described first and second embodiments, the step portion 29 is configured by the rear end portion of the protrusion 27 in the clip attachment direction Di, but this is not limiting. In the clip attachment seat 10 of the above-described first embodiment, for example, the step portion 29 may be configured by a protrusion provided locally in a portion corresponding to the middle portion of the inclined surface 25 on the back surface of the insertion side portion 23. This also applies to the clip attachment seat 10 of the above-described second embodiment.

[0059] In the above-described first and second embodiments, the clip mounting seat 10 has the leg portion 11, but this is not limited thereto. The clip mounting seat 10 does not have the leg portion 11 and is composed only of the mounting plate portion 15. In this case, the clip mounting seat 10 may be provided in a manner that does not protrude from the lower panel 5.

[0060] In the above modified example, the case where the relief surface 31 is formed at the tip of the step portion 29 is applied to the clip mounting seat 10 of the first embodiment has been described, but this is not limiting. The clip mounting seat 10 of the second embodiment can also adopt the case where the relief surface 31 is formed at the tip of the step portion 29.

[0061] In the above-described first and second embodiments, the clip mounting seat 10 is provided on the rear spoiler 1, but this is not limiting. The clip mounting seat 10 according to the present disclosure can be applied to various vehicle parts, such as spoilers other than rear spoilers, vehicle exterior parts such as bumper grilles and garnishes, and vehicle interior parts such as door trims and pillar trims.
