Mode for Carrying Out the Invention

[0025] In FIG. 1, the front part of the vehicle 12 in the present embodiment is shown in a side view seen from the outer side in the vehicle width direction (right side of the vehicle), and in FIG. 2, the fairing device 10 according to the present embodiment is shown in an exploded perspective view seen from the rear of the vehicle and from the inner side in the vehicle width direction. Further, in FIG. 3, the fairing device 10 is shown in a bottom view seen from below, and in FIG. ******, the fairing device 10 is shown in a front view seen from the front of the vehicle. In the drawings, the front of the vehicle is indicated by an arrow FR, the outer side in the vehicle width direction is indicated by an arrow OUT, and the upper side is indicated by an arrow UP.

[0026] As shown in FIG. 1, the fairing device 10 according to the present embodiment is installed inside the front end portion of the vehicle body 12A and is disposed on the front side of the front wheel 12B of the vehicle 12. The lower surface (bottom surface) of the vehicle body 12A is covered by a plate-like cover 12C, and a substantially rectangular opening 12D (see FIG. 3) is formed through the cover 12C below the fairing device 10.

[0027] As shown in Figures 1 to 4, the flow straightening device 10 is provided with a resin-made, roughly rectangular box-shaped flow straightening fluid 14, which serves as the flow straightening section. The flow straightening fluid 14 is rotatable in the deployment direction A and the storage direction B, and can be positioned in a deployed position (the position indicated by the dashed line in Figure 1) and a stored position (the position indicated by the dashed line in Figure 1). When the flow straightening fluid 14 is positioned in the deployed position, it protrudes from the underside of the vehicle body 12A through the deployment hole 12D of the cover 12C.

[0028] At the front end of the fluid rectifier 14, a curved rectangular plate-shaped rotating plate 14A (see Figures 5 and 6(A)) is integrally formed as a rotating part on the rear side of the rotational axis of the fluid rectifier 14. The rotating plate 14A protrudes inward in the vehicle width direction and is curved along the rotational circumferential direction of the fluid rectifier 14.

[0029] A drive unit 16 (see Figures 2 and 5) is assembled on the inside in the vehicle width direction of the front end of the rectifier fluid 14, and the drive unit 16 is fixed inside the front end of the vehicle body 12A.

[0030] The drive unit 16 is provided with a resin stand 18 that is substantially cylindrical and serves as a rotating shaft. The axial direction of the stand 18 is in the vehicle width direction, and a predetermined number (3 in this embodiment) of coupling screws 20 connect (fasten) the rectifying fluid 14 to the outer end of the stand 18 in the vehicle width direction. The stand 18 constitutes the rectifying fluid 14, and the rectifying fluid 14 is rotatable about the stand 18 as its central axis.

[0031] Near the outer end of the stand 18 in the vehicle width direction, an annular seal cylinder 18A is integrally formed coaxially as a sealing part. The seal cylinder 18A has an L-shaped cross-section and is provided with a bottom wall and side walls. The bottom wall of the seal cylinder 18A is an annular plate shape and is integral with the stand 18, and the side walls of the seal cylinder 18A are cylindrical and protrude inward in the vehicle width direction from the radially outer end of the bottom wall of the seal cylinder 18A. A rotating plate 14A of the rectifying fluid 14 is arranged near the radially outer side of the side wall of the seal cylinder 18A, and the rotating plate 14A is curved along the side wall of the seal cylinder 18A.

[0032] On the inner side of the stand 18 in the vehicle width direction, a box-shaped resin case 24 is provided as a support member constituting the support body 22, and the inside of the case 24 is open to the inside in the vehicle width direction. A substantially bottomed cylindrical housing tube 24A is formed in the lower part of the case 24, and the axial direction of the housing tube 24A is in the vehicle width direction, and its interior is in communication with the upper part of the case 24. A cylindrical support tube 24B, which serves as a first support part, is integrally formed coaxially on the bottom wall (outer wall in the vehicle width direction) of the housing tube 24A, and the support tube 24B penetrates the bottom wall of the housing tube 24A, and its interior is open to the outside in the vehicle width direction.

[0033] The stand 18 is coaxially fitted inside the support cylinder 24B, thereby allowing the support cylinder 24B to rotatably support the stand 18, and the stand 18 is coaxially inserted into the housing cylinder 24A. The bottom wall of the seal cylinder 18A of the stand 18 abuts against the support cylinder 24B from the outside in the vehicle width direction, thereby preventing the stand 18 from moving inward in the vehicle width direction, and creating a gap between the bottom wall of the housing cylinder 24A and the side wall of the seal cylinder 18A. An annular seal ring 26 is inserted between the support cylinder 24B and the seal cylinder 18A as a sealing member, and the seal ring 26 is made of rubber and has sealing properties. The seal ring 26 is sandwiched between the support cylinder 24B and the side wall of the seal cylinder 18A and elastically contracts, and the seal ring 26 seals the space between the case 24 and the stand 18, limiting the ingress of water into the case 24.

[0034] A substantially curved rectangular plate-shaped regulating plate 24C (see Figures 3, 4, and 6(A)) is integrally formed at the lower part of the housing cylinder 24A of the case 24, and the regulating plate 24C is curved along the circumferential direction of the housing cylinder 24A. The regulating plate 24C protrudes outward in the vehicle width direction and is positioned near the radially outer side of the side wall of the seal cylinder 18A of the stand 18, and reaches the outer end position in the vehicle width direction of the side wall of the seal cylinder 18A, and the regulating plate 24C is curved along the side wall of the seal cylinder 18A. When the rectifying fluid 14 is rotated to the deployed position, the side surface A in the deployment direction of the rotating plate 14A of the rectifying fluid 14 comes into contact with the side surface B in the storage direction of the regulating plate 24C, thereby restricting the rotation of the rotating plate 14A in the deployment direction A, and thus restricting the rotation of the rectifying fluid 14 in the deployment direction A.

[0035] A resin motor base 28, which serves as a holding member for the support 22, is housed inside the case 24, and the outer circumference of the motor base 28 is fitted into the inner circumference of the case 24. A pair of fixing screws 30 are driven through the upper and lower middle portion of the motor base 28, and the pair of fixing screws 30 are screwed into the bottom wall (outer wall in the vehicle width direction) of the case 24, thereby fixing (fastening) the motor base 28 to the case 24.

[0036] A roughly bottomed, elliptical retaining cylinder 28A is integrally formed on the upper part of the motor base 28, and the retaining cylinder 28A protrudes inward in the vehicle width direction, while its interior is open to the inward direction in the vehicle width direction.

[0037] A substantially bottomed cylindrical insertion tube 28B is integrally formed on the lower part of the motor base 28 as an insertion part. The insertion tube 28B protrudes inward in the vehicle width direction, and its interior is open to the outside in the vehicle width direction. The insertion tube 28B is arranged coaxially with the housing tube 24A of the case 24, and the stand 18 is inserted coaxially into the insertion tube 28B. A substantially bottomed cylindrical fitting tube 28C is integrally formed coaxially on the bottom wall (inner wall in the vehicle width direction) of the insertion tube 28B as a second support part (fitting part). The fitting tube 28C protrudes inward in the vehicle width direction from the bottom wall of the insertion tube 28B. The inside of the fitting tube 28C is open to the insertion tube 28B, and the inner end of the stand 18 in the vehicle width direction is coaxially fitted into the inside of the fitting tube 28C, thereby supporting the stand 18 so that it can rotate.

[0038] A box-shaped resin cover 32 is provided on the inner side of the case 24 and motor base 28 in the vehicle width direction, serving as a covering member for the support 22. The inside of the cover 32 is open to the outside in the vehicle width direction. The inner end of the case 24 in the vehicle width direction is fitted and fixed inside the outer end of the cover 32 in the vehicle width direction, and the cover 32 covers and seals the inner side of the case 24 and motor base 28 in the vehicle width direction.

[0039] The case 24 and cover 32 are fixed inside the front end of the vehicle body 12A, thereby installing the rectifier 10 inside the front end of the vehicle body 12A.

[0040] A motor 42, serving as a drive mechanism, is provided in the upper part of the interior of the case 24 and cover 32. The motor 42 has a roughly elliptical cylindrical body 42A, which is fitted and held in place by being inserted into the retaining cylinder 28A of the motor base 28 from the inside in the vehicle width direction. An output shaft 42B extends outward from the body 42A in the vehicle width direction, and the output shaft 42B passes through the motor base 28 and extends outward from the motor base 28 in the vehicle width direction. When the motor 42 is driven, the output shaft 42B rotates.

[0041] A resin first-stage worm 44 is provided on the outer side of the motor 42 in the vehicle width direction, and the outer end of the first-stage worm 44 in the vehicle width direction is rotatably supported on the bottom wall of the case 24. The output shaft 42B of the motor 42 is inserted coaxially into the first-stage worm 44 from the inner side in the vehicle width direction, and as the output shaft 42B rotates, the first-stage worm 44 rotates together with the output shaft 42B.

[0042] Below the first-stage worm 44, a metal output worm 46 is provided, and the output worm 46 is rotatably supported between the bottom wall of the case 24 and the motor base 28. A resin first-stage gear 48 (worm wheel) is supported coaxially on the front side of the output worm 46, and the first-stage gear 48 rotates together with the output worm 46. The first-stage gear 48 meshes with the first-stage worm 44, and as the first-stage worm 44 rotates, the first-stage gear 48 and the output worm 46 rotate together.

[0043] Below the output worm 46, a metal, substantially cylindrical output gear 50 (worm wheel) is provided as a drive member. The output gear 50 is rotatably supported by a stand 18, which is coaxially fitted inside the output gear 50. The output gear 50 is movable in the vehicle width direction (axial direction) relative to the stand 18, and the output gear 50 is in contact with the support cylinder 24B of the case 24 from the inside in the vehicle width direction. The output gear 50 meshes with the output worm 46, limiting its rotation, and the output gear 50 rotates when the output worm 46 rotates.

[0044] A metal, substantially cylindrical clutch 52 is provided on the inside of the output gear 50 in the vehicle width direction, and the clutch 52 is supported by a stand 18 which is coaxially fitted inside the clutch 52. The clutch 52 is made rotatable together with the stand 18 and movable axially (in the vehicle width direction) relative to the stand 18, and the clutch 52 engages with the output gear 50 and rotates together with the output gear 50.

[0045] A metal coil spring 54 is provided on the inside of the clutch 52 in the vehicle width direction as a biasing member, and a stand 18 is inserted coaxially into the coil spring 54. A metal push nut 56, which is roughly annular in shape, is fitted and fixed to the inside end of the stand 18 in the vehicle width direction as a locking member, and the coil spring 54 is stretched between the push nut 56 and the clutch 52. The coil spring 54 is compressed in the axial direction, and the coil spring 54 biases the clutch 52 and the output gear 50 outward in the vehicle width direction, thereby limiting the disengagement of the output gear 50 and the clutch 52.

[0046] Next, the operation of this embodiment will be explained.

[0047] In the flow straightening device 10 with the above configuration, when the rectifying fluid 14 is deployed from the storage position (dashed line position in Figure 1), the motor 42 in the drive unit 16 is driven forward, and the output shaft 42B, first stage worm 44, first stage gear 48 and output worm 46 are rotated, causing the output gear 50, clutch 52 and rectifying fluid 14 (including the stand 18) to rotate together in the deployment direction A, and the rectifying fluid 14 is positioned in the deployed position (dotted line position in Figure 1). As a result, the rectifying fluid 14 is positioned on the underside of the vehicle body 12A and in front of the front wheels 12B of the vehicle 12, suppressing the airflow (airflow) of the vehicle 12 to the front wheels 12B (directing the airflow to the underside of the front wheels 12B), thereby suppressing the increase in air pressure on the front side of the front wheels 12B, and thus suppressing the air resistance and lift of the vehicle 12.

[0048] On the other hand, when the fluid 14 is retracted from the deployed position, the motor 42 in the drive unit 16 is driven in reverse, causing the output shaft 42B, the first stage worm 44, the first stage gear 48, and the output worm 46 to rotate, so that the output gear 50, the clutch 52, and the fluid 14 (including the stand 18) are rotated together in the retraction direction B, and the fluid 14 is positioned in the retraction position.

[0049] Furthermore, when the rectifying fluid 14 is rotated to the deployed position, the side of the rotating plate 14A of the rectifying fluid 14 in the deployment direction A comes into contact with the side of the regulating plate 24C of the support 22 (case 24) in the storage direction B, thereby restricting the rotation of the rotating plate 14A in the deployment direction A, and thus restricting the rotation of the rectifying fluid 14 in the deployment direction A.

[0050] Here, the regulating plate 24C of case 24 covers the space between the rectifying fluid 14 and case 24 (the gap between the side wall of the seal cylinder 18A of stand 18 and the bottom wall of the housing cylinder 24A of case 24). Therefore, the regulating plate 24C can prevent foreign matter (e.g., mud) from entering the space between the rectifying fluid 14 and case 24 from below. This prevents the rotation of the rectifying fluid 14 relative to case 24 from being hindered by foreign matter.

[0051] Furthermore, the restricting plate 24C of case 24 extends radially outward from the space between the fluid rectifier 14 and case 24 to the side wall of the seal cylinder 18A of stand 18 on the fluid rectifier 14 side (outward in the vehicle width direction). Therefore, the restricting plate 24C can effectively prevent foreign matter from entering the space between the fluid rectifier 14 and case 24 from below.

[0052] Furthermore, as described above, the rotating plate 14A of the rectifying fluid 14 comes into contact with the regulating plate 24C of the case 24, thereby restricting the rotation of the rectifying fluid 14. Therefore, the rotation of the rectifying fluid 14 can be restricted by the regulating plate 24C, and the configuration can be simplified.

[0053] (modified version) Figure 6(B) shows a cross-sectional view (cross-sectional view at line 6-6 in Figure 4) of a modified example of the above embodiment of the rectifier 60 as seen from the inside in the vehicle width direction.

[0054] As shown in Figure 6(B), in the rectifier 60 according to this modified example, a substantially curved rectangular plate-shaped covering plate 24D is integrally formed on the upper part of the housing cylinder 24A in the support 22 (case 24) of the drive unit 16, and the covering plate 24D is curved along the circumferential direction of the housing cylinder 24A. The covering plate 24D protrudes outward in the vehicle width direction and is positioned near the radially outer side of the side wall of the seal cylinder 18A of the stand 18, and reaches the outer end position in the vehicle width direction of the side wall of the seal cylinder 18A, and the covering plate 24D is curved along the side wall of the seal cylinder 18A.

[0055] In this modified example, the same actions and effects as those of the above embodiment can be achieved.

[0056] Furthermore, the covering plate 24D of case 24 covers the space between the rectifying fluid 14 and case 24 (the gap between the side wall of the seal cylinder 18A of stand 18 and the bottom wall of the housing cylinder 24A of case 24). Therefore, the covering plate 24D can prevent foreign matter (such as mud) from entering the space between the rectifying fluid 14 and case 24 from above.

[0057] Furthermore, the covering plate 24D of case 24 extends radially outward from the space between the fluid rectifier 14 and case 24 to the side wall of the seal cylinder 18A of stand 18 on the fluid rectifier 14 side (outward in the vehicle width direction). Therefore, the covering plate 24D can effectively suppress the intrusion of foreign matter from above into the space between the fluid rectifier 14 and case 24.

[0058] In the above embodiment (including modified versions), the restricting plate 24C and the covering plate 24D (covering portion) are arranged on the lower and upper sides, respectively, between the fluid rectifier 14 and the case 24. However, the covering portion may be arranged on the front or rear side of the vehicle between the fluid rectifier 14 and the case 24. Moreover, the covering portion may be arranged on the side of the deployment hole 12D of the cover 12C between the fluid rectifier 14 and the case 24.

[0059] Furthermore, in the above embodiment (including modified examples), the rotating plate 14A is positioned on the rear side of the vehicle between the fluid rectifier 14 and the case 24. However, the rotating plate 14A may be positioned on the front, lower, or upper side of the vehicle between the fluid rectifier 14 and the case 24. Moreover, the rotating plate 14A may be positioned on the side of the deployment hole 12D of the cover 12C between the fluid rectifier 14 and the case 24. In addition, in the above modified example, the rotating plate 14A may be in contact with the covering plate 24D of the case 24 to restrict the rotation of the fluid rectifier 14.

[0060] Furthermore, in the above embodiments (including modified examples), the arrangement range of the regulating plate 24C and the covering plate 24D (covering portion) and the rotating plate 14A in the rotational direction of the fluid rectifier 14 can be arbitrarily set. For example, the arrangement range of the covering portion in the rotational direction of the fluid rectifier 14 may be 180° or more in the rotational angle range of the fluid rectifier 14.

[0061] Furthermore, in the above embodiment (including modified versions), the rotating plate 14A of the fluid rectifier 14 may cover the space between the fluid rectifier 14 and the case 24 (the gap between the side wall of the seal cylinder 18A of the stand 18 and the bottom wall of the housing cylinder 24A of the case 24). This prevents foreign matter (e.g., mud) from entering the space between the fluid rectifier 14 and the case 24, which can be suppressed by the rotating plate 14A.

[0062] Furthermore, in the above embodiment (including modified versions), the rotating plate 14A of the fluid rectifier 14 may extend from between the fluid rectifier 14 and the case 24 to the radially outward side of the housing cylinder 24A on the case 24 side (inward in the vehicle width direction). This allows the rotating plate 14A to effectively suppress the intrusion of foreign matter between the fluid rectifier 14 and the case 24.

[0063] Furthermore, in the above embodiment (including modified examples), the rotating plate 14A of the fluid rectifier 14 is positioned above the space between the fluid rectifier 14 and the case 24, thereby preventing foreign matter from entering the space between the fluid rectifier 14 and the case 24 from above.

[0064] Furthermore, in the above embodiment (including modified versions), when the rotating plate 14A of the rectifying fluid 14 comes into contact with the covering portion (regulating plate 24C or covering plate 24D) of the case 24 and the rotation of the rectifying fluid 14 is restricted, the side surface of the rotating plate 14A and the side surface of the covering portion may be fitted together (particularly in surface contact). This effectively prevents foreign matter from entering between the rectifying fluid 14 and the case 24, through the covering portion and the rotating plate 14A.

[0065] Furthermore, in the above embodiment (including modified examples), a rotating plate 14A is provided in addition to the stand 18 of the fluid rectifier 14. However, the rotating plate 14A may also be provided on the stand 18. [Explanation of symbols]
