JP 2001-233149 A Japanese Patent Laid-Open No. 2006-219019

  A deflector and an air spoiler (hereinafter collectively referred to as a deflector) may be provided not only near the front wheel of the vehicle but also near the rear wheel in order to prevent air from being caught in the tire house of the rear wheel.

  Further, when the deflector is provided integrally with the bumper or the like, the material of the deflector is the same material as the bumper or the like, for example, a hard material such as hard resin or vinyl chloride. For this reason, when a deflector contacts an obstruction, a deflector will be damaged or deform | transformed. In order to prevent such damage and deformation of the deflector, it is conceivable that the deflector is separated from a bumper and formed of a soft material.

  When the deflector made of such a soft material is provided in the vicinity of the rear wheel, it is conceivable to attach the deflector to the lower surface of the side step molding using a plurality of fastening clips or rivets. However, when the soft material is fixed with a fastening clip or a rivet, the fastening may not be performed reliably. Therefore, it is conceivable that a hard insert member is interposed between the deflector and the side step molding, and the deflector is fastened to the side step molding with a fastening clip or a rivet together with the insert member.

  As above-mentioned, when attaching the deflector of a soft material to a side step molding, while inserting an insert member, it can employ | adopt fixing to a side step molding with a some fastening clip or a rivet. However, such an attachment structure has a problem that the material cost increases because the number of parts required for attaching the deflector, such as an insert member and a fastening clip, is large. Furthermore, as the number of parts increases, the number of work steps in the deflector mounting work increases, which causes a problem in that the work efficiency in the mounting work is reduced.

  The present invention has been made in view of the above points, and the object of the present invention is to easily attach a deflector formed of a soft material to a side step molding without using an insert member or a fastening part. An object of the present invention is to provide a mounting structure for a deflector that can be used.

  A first aspect of the present invention is a mounting structure for a deflector that is attached to a bottom plate of a side step molding of a vehicle. The bottom plate has at least one notch formed at an inner end in a vehicle width direction. At least one opening hole penetrating in the plate thickness direction is formed at the outer end in the width direction, and the deflector is a soft elastic body, and a contact plate whose upper surface is in contact with the lower surface of the bottom plate, and the contact plate A rectifying plate for rectifying air when the vehicle travels, and first and second attachment members provided on the upper surface of the contact plate for attaching the deflector to the bottom plate, respectively. The first mounting member protrudes upward from a portion corresponding to the notch on the upper surface of the contact plate, and has the same number of first protrusions as the notch and a vehicle on the upper end surface of the first protrusion. Before and after The lower surface has a parallel portion that is parallel to the contact plate, and the first protrusion portion is formed on the notch with the parallel portion riding on the upper surface of the bottom plate. The second mounting member is fitted and engaged, and protrudes upward from a portion corresponding to the opening hole on the upper surface of the contact plate, and has the same number of second protrusions as the opening hole, in which a thick portion is formed. And the second protrusion is inserted into and engaged with the opening hole in a state where the thick part is caught by the peripheral edge of the opening hole on the upper surface side of the bottom plate. To do.

  As described above, in the first invention, the first and second mounting members provided on the upper surface of the contact plate of the deflector are respectively engaged with the notch and the opening hole formed in the side step molding. Thus, the deflector can be attached to the side step molding. Therefore, when attaching a deflector, it is not necessary to use an insert member or a fastening part, so that the material cost can be reduced. Furthermore, since the increase in the work man-hour accompanying the increase in the number of parts can be suppressed, it is possible to suppress a decrease in work efficiency in the mounting work.

  Further, by utilizing the spring characteristic of the soft elastic body, the second mounting member can be easily engaged with the opening hole while the first mounting member is engaged with the notch. Specifically, with the parallel portion placed on the upper surface of the bottom plate, the second protrusion portion having the thick portion is inserted into the opening hole from the lower surface side of the bottom plate while the first protrusion portion is fitted and engaged with the notch portion. The deflector can be attached to the side step molding by inserting and pulling out the thick wall portion from the opening hole to the upper surface side of the bottom plate. Thus, since the deflector can be easily attached, the working efficiency in the attaching work of the deflector can be greatly improved.

  According to a second invention, in the first invention, the gap between the first protrusion and the second protrusion is in the state before the deflector is attached to the side step molding. It is characterized in that it is set smaller than the distance from the hole.

  Thus, in the second invention, the distance between the first protrusion and the second protrusion is smaller than the distance between the notch and the opening hole in the pre-attachment state before the deflector is attached to the side step molding. Is set. For this reason, when attaching the deflector to the side step molding, the deflector is attached while pulling the second protrusion outward so that the distance between the first protrusion and the second protrusion is widened. Therefore, in the mounted state, the deflector tries to return to the state before mounting due to the spring characteristic of the soft elastic body. Thereby, the 1st attachment member and the notch which have the 1st projection part can be strongly engaged. Therefore, in the second invention, a stable mounting state of the deflector can be achieved as compared with the case where the interval between the first protruding portion and the second protruding portion is equal to the interval between the notched portion and the opening hole in the state before mounting. Can be maintained.

  According to a third invention, in the first or second invention, at least one of an interval between the upper surface of the contact plate and the lower surface of the parallel portion and an interval between the upper surface of the contact plate and the lower end of the thick portion is set. In the state before the deflector is attached to the side step molding, the thickness is set smaller than the thickness of the bottom plate.

  Thus, in the state before attachment, if the distance between the lower surface of the parallel portion and the upper surface of the contact plate is set smaller than the thickness of the bottom plate, the first protrusion portion extends in the vertical direction in the attachment state. For this reason, a 1st projection part tends to return to the state before attachment with the spring characteristic which a soft elastic body has. As a result, the parallel portion is pulled downward and the contact plate is pulled upward. Therefore, the first mounting member having the first protrusion and the notch can be strongly engaged.

  Moreover, in the state before attachment, if the space | interval of the lower end of a thick part and the upper surface of a contact plate is set smaller than the thickness of a bottom plate, a 2nd projection part will be extended in an up-down direction in the attachment state. For this reason, a 2nd projection part tries to return to the state before attachment with the spring characteristic which a soft elastic body has. As a result, the thick portion is pulled downward and the contact plate is pulled upward. Therefore, the second attachment member having the second protrusion and the opening hole can be strongly engaged.

  As described above, in the third invention, the distance between the upper surface of the contact plate and the lower surface of the parallel portion and the distance between the upper surface of the contact plate and the lower end of the thick portion are the thickness of the bottom plate of the side step molding in the pre-mounting state. Compared with the case where it is equal to, the stable attachment state of a deflector can be maintained reliably.

  A fourth invention is characterized in that, in any one of the first to third inventions, a through-hole penetrating in a direction parallel to the contact plate is formed in the thick part in the thick part. To do.

  Thus, since the through-hole is formed in the central portion of the thick portion of the second protrusion, when the thick portion is pulled out from the opening hole to the upper surface side of the bottom plate, the thick portion is reliably contracted. be able to. Therefore, the deflector can be attached more smoothly as compared with the case where no through hole is provided in the thick portion.

  According to the present invention, in order to increase the stability during traveling of the vehicle, even when the deflector is attached to the bottom plate of the side step molding, the insert member or the fastening member is provided by providing two kinds of attachment members on the deflector of the soft elastic body. The deflector can be attached without using parts or the like. Therefore, when attaching a deflector, it is not necessary to use an insert member or a fastening part, so that the material cost can be reduced. Furthermore, since the increase in the work man-hour accompanying the increase in the number of parts can be suppressed, it is possible to suppress a decrease in work efficiency in the mounting work.

  Further, according to the present invention, by utilizing the spring characteristic of the soft elastic body, the second protrusion having the thick portion with the first mounting member engaged with the notch portion of the bottom plate of the side step molding. The deflector can be attached by inserting the portion into the opening hole from the lower surface side of the bottom plate and pulling out the thick portion from the opening hole to the upper surface side of the bottom plate. Thus, since the deflector can be easily attached, the working efficiency in the attaching work of the deflector can be greatly improved.

For this reason, chamfering is given to the front-end | tip part (vehicle width direction inner side edge part) of the protruding end part 2b so that the protruding end part 2b can be smoothly inserted in the space 16. FIG. Two rectangular opening holes 8 penetrating in the plate thickness direction are formed in the vicinity of the rear end in the vehicle longitudinal direction of the bottom plate 2a and at the outer end in the vehicle width direction.

  A deflector 4 is attached to the lower surface of the bottom plate 2a of the side step molding 2 in the vicinity of the rear end in the vehicle front-rear direction (in front of the rear wheel 3). The deflector 4 is a soft elastic body formed of ethylene propylene rubber (hereinafter referred to as EPDM), and is attached so that the upper surface is in contact with the lower surface of the bottom plate 2a of the side step molding 2, as shown in FIGS. And a current plate 6 extending downward from the lower surface of the contact plate 5. The rectifying plate 6 extends in the vehicle width direction, and the length in the vehicle width direction is substantially the same as that of the contact plate 5, so that air is not caught in the tire house 23 of the rear wheel 3 while the vehicle is running. It plays the role of rectifying the air flow in the vicinity of the wheel 3. Further, two types of attachment members 9 and 10 to be described later are provided on the upper surface of the contact plate 5 in order to attach the deflector 4 to the bottom plate 2a.

  As shown in FIG. 4, the contact plate 5 has a substantially rectangular shape, and extends from the inner end of the bottom plate 2 a to the outer side in the vehicle width direction of the opening hole 8 in the vehicle width direction. Further, the contact plate 5 extends in the vehicle front side with respect to the vehicle front side notch portion 7 and the opening hole 8 in the vehicle front-rear direction, and further on the vehicle rear side with respect to the vehicle rear side notch portion 7 and the opening hole 8. (See FIGS. 7 and 8). On the upper surface of the contact plate 5, a first attachment member 9 is integrally formed at the inner end in the vehicle width direction and attached to the notch 7, and the first attachment member 9 is attached to the opening hole 8 at the outer end in the vehicle width direction. 2 The attachment member 10 is integrally formed.

  The first attachment member 9 includes a first engagement piece portion (first protrusion) 12 and a parallel portion 11. The first engagement piece 12 projects upward from the upper surface of the contact plate 5, specifically, from the portion corresponding to the notch 7 in the attached state. Further, the first engagement piece 12 is provided in the same number as the two notches 7, 7, that is, two, respectively, and the inner dimensions (notch depth and notch length) of the notch 7 respectively. It is a rectangular bar-shaped member having a cross section of the same size.

  The parallel portion 11 is a plate-like member provided on the upper end surface of the first engagement piece portion 12 so as to extend in the vehicle front-rear direction, and is formed so that the lower surface thereof is parallel to the contact plate 5. ing. The parallel portion 11 has a length equal to that of the first engagement piece portion 12 in the vehicle width direction, and extends to the vehicle front side from the first engagement piece portion 12 on the vehicle front side in the vehicle front-rear direction. The first engagement piece 12 on the vehicle rear side extends to the vehicle rear side.

  In the attached state, as shown in FIGS. 6 and 7, the first engagement piece 12 is fitted and engaged with the notch 7 with the parallel portion 11 riding on the upper surface of the bottom plate 2 a. In other words, in the mounted state, the projecting end 2b of the bottom plate 2a of the side step molding 2 is in a rectangular space 16 surrounded by the parallel portion 11, the contact plate 5 and the two first engaging pieces 12, 12. It is fitted and engaged.

  As described above, the first engagement pieces 12, 12 are inserted into the notches 7, 7 with the bottom plate 2 a sandwiched between the parallel portion 11 and the contact plate 5, thereby The member 9 is engaged with the notch 7.

  In order to strongly engage the first mounting member 9 and the notch portion 7, the distance between the lower surface of the parallel portion 11 and the upper surface of the contact plate 5, that is, the height of the first engagement piece 12 is determined by a deflector. In the state before attachment before attaching 4 to the side step molding 2, it is set slightly smaller than the thickness of the bottom plate 2a (t in FIG. 3).

  On the other hand, the second attachment member 10 has a second engagement piece 13 (second protrusion) 13 protruding upward from the upper surface of the contact plate 5, specifically, the portion corresponding to the opening hole 8 in the attached state. have. As shown in FIG. 4, the second engagement piece portion 13 is provided in the same number as the two opening holes 8, that is, two, and each has a thick portion 13 b.

  The 2nd engagement piece part 13 is a plate-shaped member, The both surfaces have faced the vehicle front side and the rear side. A base end portion 13 a below the thick portion 13 b of the second engagement piece 13 is formed in a rectangular cross section having the same size as the inner size of the opening hole 8. Further, the tip end portion 13c of the second engagement piece portion 13 above the thick portion 13b increases in thickness so that the second engagement piece portion 13 can be smoothly inserted into the opening hole 8. It is getting smaller.

  The thick portion 13b is formed by thickening the front and rear surfaces of the vehicle. Furthermore, a through-hole 14 that penetrates in the vehicle width direction is formed in the thick portion 13b in the center portion. That is, the thick part 13b is formed in a substantially cylindrical shape extending in the vehicle width direction.

  And the two 2nd engagement piece parts 13 and 13 are each inserted in the two opening holes 8 and 8 in the attachment state. Specifically, as shown in FIGS. 6 and 8, the base end portion 13 a is fitted in the opening hole 8, and the thick wall portion 13 b is caught on the peripheral edge portion of the opening hole 8 on the upper surface side of the bottom plate 2 a. It is locked in a state. As described above, the second engagement piece 13 is inserted into and engaged with the opening hole 8 in a state where the thick portion 13b is hooked on the peripheral edge of the opening hole 8 on the upper surface side of the bottom plate 2a. The second mounting member 10 having the two engaging pieces 13, 13 is engaged with the opening hole 8.

  In order to strongly engage the second mounting member 10 and the opening hole 8, the distance between the lower end of the thick portion 13b and the upper surface of the contact plate 5 is slightly smaller than the thickness of the bottom plate 2a in the state before mounting. Is set.

  Further, in order to strongly engage the first mounting member 9 and the notch portion 7, the distance between the first engagement piece portion 12 and the second engagement piece portion 13 is the same as that of the notch portion 7 in the state before attachment. It is set slightly smaller than the interval with the opening hole 8. Here, the distance between the first engagement piece 12 and the second engagement piece 13 is, as shown in FIG. 5, the side surface on the outer side in the vehicle width direction of the first engagement piece 12 and the second engagement. The distance (A in FIG. 5) with the side surface inside the vehicle width direction of the piece 13 is indicated. Further, the interval between the notch 7 and the opening hole 8 is defined as an outer surface in the vehicle width direction on the inner peripheral surface of the notch 7 and an inner surface in the vehicle width direction on the inner peripheral surface of the opening hole 8. The interval (a in FIG. 3).

-Mounting method-
With reference to FIG. 9, the attachment method of the deflector 4 which has the attachment structure of this embodiment is demonstrated. When attaching the deflector 4 to the side step molding 2, first, the first attachment member 9 is engaged with the notch 7 formed in the bottom plate 2 a of the side step molding 2. Specifically, the parallel portion 11 is placed on the upper surface of the bottom plate 2a while the two first engaging pieces 12 and 12 are fitted into the two notches 7 and 7 from the inner side in the vehicle width direction.

  Next, the second mounting member 10 is engaged with the opening hole 8 of the bottom plate 2 a of the side step molding 2 while the first mounting member 9 is engaged with the notch 7. Specifically, with the parallel portion 11 placed on the upper surface of the bottom plate 2a, the two second engagement piece portions 13, 13 are connected to the bottom plate while the first engagement piece portion 12 is engaged with the notch portion 7. It inserts into the two opening holes 8 and 8 from the lower surface side of 2a. When the distal end portion 13c of the second engagement piece 13 protrudes from the opening hole 8 to the upper surface side of the bottom plate 2a, the distal end portion 13c is pulled upward (inside the side step molding 2). When the distal end portion 13c is pulled up in this way, the thick portion 13b of the second engagement piece portion 13 is elastically deformed and contracted to substantially the same size as the inner size of the opening hole 8 due to the spring characteristic of the soft elastic body. Thereby, the thick part 13b penetrates the opening hole 8 from the lower surface side of the bottom plate 2a. The thick portion 13b penetrating the opening hole 8 is elastically restored to the original shape (substantially cylindrical) and is in a state of being caught by the peripheral edge portion of the opening hole 8 on the upper surface side of the bottom plate 2a.

  Thus, the attachment work of the deflector 4 is completed.

-Effect-
In the present embodiment, the first and second attachment members 9 and 10 provided on the upper surface of the contact plate 5 of the deflector 4 are respectively associated with the notch portion 7 and the opening hole 8 formed in the side step molding 2. By combining, the deflector 4 can be attached to the side step molding 2. Accordingly, when the deflector 4 is attached, it is not necessary to use an insert member or a fastening part, so that the material cost can be reduced. Furthermore, since the increase in the work man-hour accompanying the increase in the number of parts can be suppressed, it is possible to suppress a decrease in work efficiency in the mounting work.

  Further, by utilizing the spring characteristic of the soft elastic body, the second mounting member 10 can be easily engaged with the opening hole 8 while the first mounting member 9 is engaged with the notch 7. . Specifically, the second engagement piece portion having the thick portion 13b while the first engagement piece portion 12 is fitted and engaged with the notch portion 7 with the parallel portion 11 placed on the upper surface of the bottom plate 2a. The deflector 4 can be attached to the side step molding 2 by inserting 13 into the opening hole 8 from the lower surface side of the bottom plate 2a and pulling out the thick portion 13b from the opening hole 8 to the upper surface side of the bottom plate 2a. Thus, since the deflector 4 can be easily attached to the side step molding 2, work efficiency in the attaching work of the deflector 4 can be greatly improved.

  Further, in the present embodiment, the interval between the first engagement piece 12 and the second engagement piece 13 is set slightly smaller than the interval between the notch 7 and the opening hole 8 in the pre-attachment state. ing. For this reason, when attaching the deflector 4 to the side step molding 2, the second engagement piece 13 is pulled outward so that the distance between the first engagement piece 12 and the second engagement piece 13 is widened. While installing the deflector 4. Therefore, in the mounted state, the deflector 4 tries to return to the state before mounting due to the spring characteristic of the soft elastic body. Thereby, the 1st attachment member 9 and the notch part 7 which have the 1st engagement piece part 12 can be engaged strongly. Therefore, compared with the case where the space | interval of the 1st engagement piece part 12 and the 2nd engagement piece part 13 is equal to the space | interval of the notch part 7 and the opening hole 8 in the state before attachment, the deflector 4 was stabilized. The mounting state can be maintained.

  Moreover, in this embodiment, the space | interval of the lower surface of the parallel part 11 and the upper surface of the contact plate 5 is set slightly smaller than the thickness of the bottom plate 2a in the state before attachment. For this reason, the 1st engagement piece part 12 is extended in the up-down direction in the attachment state. Therefore, the 1st engagement piece part 12 tends to return to the state before attachment with the spring characteristic which a soft elastic body has. Thereby, the parallel part 11 is pulled downward and the contact plate 5 is pulled upward. Therefore, the first attachment member 9 having the first engagement piece 12 and the notch 7 can be strongly engaged.

  Furthermore, the distance between the lower end of the thick portion 13b and the upper surface of the contact plate 5 is also set slightly smaller than the thickness of the bottom plate 2a in the state before attachment. For this reason, the 2nd engagement piece part 13 is extended in the up-down direction in the attachment state. Therefore, the 2nd engagement piece part 13 tends to return to the state before attachment with the spring characteristic which a soft elastic body has. Thereby, the thick portion 13b is pulled downward, and the contact plate 5 is pulled upward. Therefore, the second mounting member 10 having the second engagement piece 13 and the opening hole 8 can be strongly engaged.

  As described above, in this embodiment, the distance between the upper surface of the contact plate 5 and the lower surface of the parallel portion 11 and the distance between the upper surface of the contact plate 5 and the lower end of the thick portion 13b are the side step molding 2 in the pre-mounting state. Compared with the case where it is equal to the thickness of the bottom plate 2a, the stable attachment state of the deflector 4 can be more reliably maintained.

  Furthermore, in this embodiment, since the through-hole 14 is formed in the center part in the thick part 13b of the 2nd engagement piece part 13, the thick part 13b is formed from the opening hole 8 to the upper surface side of the bottom plate 2a. When pulling out, the thick portion 13b can be reliably shrunk. Therefore, compared with the case where the through-hole 14 is not provided in the thick part 13b, the attachment operation | work of the deflector 4 can be performed much more smoothly.

(Other embodiments)
In the said embodiment, although EPDM was used as a soft elastic material, the material of the deflector 4 is not limited to this. Even when it comes into contact with obstacles on the road, the deflector 4 is flexible enough not to be damaged or deformed, and the deflector 4 is rigid enough not to be deformed due to its own weight or air resistance during vehicle travel. And when attaching the deflector 4, what is necessary is just the material which has the elasticity which can exhibit a spring characteristic. As such a material, for example, soft vinyl chloride can be used.

  Moreover, in the said embodiment, although the notch 7 and the opening hole 8 were each formed in the bottom plate 2a of the side step molding 2 at two places, at least one notch 7 and the opening hole 8 are each formed. It should be. For example, if the number of the notches 7 and the opening holes 8 provided in the bottom plate 2a of the side step molding 2 is one by one, the deflector 4 can be attached more easily. On the contrary, for example, if the number of the notches 7 and the opening holes 8 is three or more, the number of the notches 7 and the openings 8 is two, respectively. The first and second attachment members 9 and 10 can be more strongly engaged by the notch portion 7 and the opening hole 8, respectively.

  In addition, in the said embodiment, although the plate-shaped member was used as the parallel part 11 with which the 1st attachment member 9 is equipped, the shape is not limited to this. Any shape may be used as long as the first engagement piece 12 is fitted and engaged with the notch 7 in a state where the parallel portion 11 is on the upper surface of the bottom plate 2a. Furthermore, in the said embodiment, although the parallel part 11 is extended further back and forth rather than the two 1st engagement piece parts 12 and 12 in the vehicle front-back direction, it is rather than the two 1st engagement piece parts 12 and 12. It does not have to protrude in the vehicle longitudinal direction. However, in order to ensure that the parallel part 11 is on the upper surface of the bottom plate 2a in the mounted state, the parallel part 11 is more vehicle-like than the first engagement piece part 12 when there is one notch part 7. It is necessary to extend in the front-rear direction.

  Furthermore, in the said embodiment, although the notch part 7 was formed in the rectangle, the shape of the notch part 7 is not limited to this, A triangular shape etc. are applicable. However, in order to strengthen the engagement with the first engagement piece 12 in the vehicle front-rear direction, a shape having corners is preferable to a smooth shape such as a semicircular shape. In addition, the cross-sectional shape of the 1st engagement piece part 12 is not limited, According to the shape of the notch part 7, the cross-sectional shape which can maintain the stable attachment state of the deflector 4 can be selected suitably. .

  Moreover, in the said embodiment, although the shape of the opening hole 8 was made into the rectangle, the shape of the opening hole 8 is not limited to this, Circular shape etc. are applicable. Further, it is not always necessary to form the through hole 14 in the thick portion 13 b of the second engagement piece 13. That is, the thick hole 13b smoothly penetrates the opening hole 8 from the lower surface side of the bottom plate 2a, and the opening hole 8 and the thick wall portion 13b are surely caught on the peripheral edge of the opening hole 8 on the upper surface side of the bottom plate 2a. Any combination is acceptable. The cross-sectional shape of the second engagement piece 13 is not limited, and a cross-sectional shape that can maintain a stable mounting state of the deflector 4 can be appropriately selected according to the shape of the opening hole 8. is there.

  Furthermore, in the said embodiment, the space | interval of the 1st engagement piece part 12 and the 2nd engagement piece part 13 was set slightly smaller than the space | interval of the notch part 7 and the opening hole 8 in the state before attachment. However, the interval between the first engagement piece portion 12 and the second engagement piece portion 13 may be made equal to the interval between the notch portion 7 and the opening hole 8 in the pre-attachment state. Thus, if the space | interval of the 1st engagement piece part 12 and the 2nd engagement piece part 13 is set, attachment of the deflector 4 will become still easier. Similarly, unlike the above-described embodiment, the distance between the upper surface of the contact plate 5 and the lower surface of the parallel portion 11 and the distance between the upper surface of the contact plate 5 and the lower end of the thick portion 13b are the same as those of the bottom plate 2a. It may be equal to the thickness of. Thus, if the space | interval of the upper surface of the contact plate 5, the lower surface of the parallel part 11, and the lower end of the thick part 13b is set, attachment of the deflector 4 will become still easier.

  In the above embodiment, the lengths of the current plate 6 and the contact plate 5 in the vehicle width direction are substantially the same. However, the deflector includes the current plate 6 having the vehicle width direction length so as to cover the entire width of the rear wheel 3. Also, the mounting structure of the present invention can be applied. As described above, by using the current plate 6 having a length in the vehicle width direction so as to cover the entire width of the rear wheel 3, air is more effectively prevented from being caught in the tire house 23 of the rear wheel 3 while the vehicle is traveling. Can be prevented.

  The present invention is not limited to the embodiments, and can be implemented in various other forms without departing from the spirit or main features thereof.

  As described above, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the present invention is useful for a deflector mounting structure and the like.
