[0024] As shown in FIG. 1, the rectifying device 10 according to the present embodiment is installed inside the front end portion of the vehicle body 12A and is disposed in front of the front wheel 12B of the vehicle 12.

[0025] ​​​​ A bottomed cylindrical coupling cylinder 14A (see Figure 7) is formed at the front end of the fluid rectifier 14. The coupling cylinder 14A is oriented axially in the vehicle width direction, and its interior is open to the inside in the vehicle width direction. A cylindrical rotating cylinder 14B, which serves as a supported part, is integrally formed on the outer side in the vehicle width direction of the bottom wall (outer wall in the vehicle width direction) of the coupling cylinder 14A. The rotating cylinder 14B is oriented axially in the vehicle width direction, and its interior is open to the inside in the vehicle width direction, communicating with the coupling cylinder 14A.

[0027] A drive unit 16 (see Figures 2 and 7) 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.

[0028] The drive unit 16 is provided with a roughly cylindrical resin stand 18 as a rotating shaft, and the axial direction of the stand 18 is in the vehicle width direction. The outer end of the stand 18 in the vehicle width direction is inserted into the coupling cylinder 14A of the fluid rectifier 14 from the inside in the vehicle width direction, and a predetermined number (3 in this embodiment) coupling screws 20 are passed through the bottom wall of the coupling cylinder 14A from the outside in the vehicle width direction and screwed into the outer end of the stand 18 in the vehicle width direction. In this way, the fluid rectifier 14 is coupled (fastened) to the stand 18, and the stand 18 is arranged coaxially with the rotating cylinder 14B of the fluid rectifier 14. Furthermore, the fluid rectifier 14 is rotatable in the deployment direction A and the storage direction B with the stand 18 as its central axis.

[0029] 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.

[0030] On the inside of the stand 18 in the vehicle width direction, a box-shaped resin case 24 is provided as the main body component of the support 22, and the inside of the case 24 is open to the inside in the vehicle width direction. A roughly bottomed cylindrical housing tube 24A is formed on the lower part of the case 24, and the axial direction of the housing tube 24A is in the vehicle width direction, and the inside is in communication with the upper part of the case 24. A cylindrical support tube 24B 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 the inside is open to the outside in the vehicle width direction.

[0031] 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 inside 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. An annular seal ring 26 is inserted between the support cylinder 24B and the seal cylinder 18A as a sealing member. The seal ring 26 is made of rubber and has sealing properties. The seal ring 26 is sandwiched between the side walls of the support cylinder 24B and the seal cylinder 18A and is elastically contracted, sealing the space between the case 24 and the stand 18, and limiting the ingress of water into the case 24.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] A box-shaped resin cover 32 is provided on the inside of the case 24 and motor base 28 in the vehicle width direction, serving as a covering member. The inside of the cover 32 is open to the outside in the vehicle width direction. The inside end of the case 24 in the vehicle width direction is fitted and fixed inside the outside end of the cover 32 in the vehicle width direction, and the cover 32 covers and seals the inside of the case 24 and motor base 28 in the vehicle width direction.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Support members 58 (see Figures 3 to 7) are provided on the front side of the vehicle for the fluid rectifier 14 and the drive unit 16.

[0044] The support member 58 is provided with a metal arm 60, which has an L-shaped cross-section, as its first part. The front portion of the arm 60 extends in the vehicle width direction, and the outer portion of the arm 60 in the vehicle width direction extends from the front portion of the arm 60 toward the rear of the vehicle. A pair of fastening screws 62 are passed through the inner end of the arm 60 in the vehicle width direction, and the pair of fastening screws 62 are screwed into the front wall of the case 24 from the front of the vehicle, thereby supporting (fastening) the arm 60 to the case 24.

[0045] The support member 58 is provided with a metal, substantially cylindrical support shaft 64 as a second part, and the axial direction of the support shaft 64 is in the vehicle width direction. Near the outer end of the support shaft 64 in the vehicle width direction, an annular plate-shaped enlarged diameter portion 64A is integrally formed, and the support shaft 64 is coaxially enlarged in the enlarged diameter portion 64A. The outer end of the support shaft 64 in the vehicle width direction passes through the rear end of the arm 60, and a nut 66 is screwed onto the outer end of the support shaft 64 in the vehicle width direction, and the rear end of the arm 60 is sandwiched between the nut 66 and the enlarged diameter portion 64A, thereby supporting (fastening) the support shaft 64 to the arm 60. The support shaft 64 is coaxially fitted into the rotating cylinder 14B of the rectifying fluid 14, and the support shaft 64 rotatably supports the rectifying fluid 14 (rotating cylinder 14B).

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

[0047] In the flow straightening device 10 with the above configuration, when the straightened fluid 14 is deployed, 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, stand 18 and straightened fluid 14 to rotate together in the deployment direction A, and the straightened fluid 14 is positioned in the deployed position (the position of the dashed line in Figure 1). As a result, the straightened 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 rectified fluid 14 is stored, the motor 42 in the drive unit 16 is driven in reverse, causing the output shaft 42B, first stage worm 44, first stage gear 48 and output worm 46 to rotate, so that the output gear 50, clutch 52, stand 18 and rectified fluid 14 rotate together in the storage direction B, and the rectified fluid 14 is positioned in the storage position (dashed line position in Figure 1).

[0049] Incidentally, the support cylinder 24B of the case 24 in the support body 22 and the fitting cylinder 28C of the motor base 28 support the stand 18. Furthermore, when the vehicle 12 is running, if an external force is applied to the rectifying fluid 14 from a protrusion on the running surface of the vehicle 12, a load is applied from the rectifying fluid 14 to the stand 18.

[0050] Here, the arm 60 of the support member 58 is supported by the case 24 of the support body 22, and the support shaft 64 of the support member 58 supports the rotating cylinder 14B of the fluid rectifier 14, thereby supporting the outer end of the stand 18 in the vehicle width direction. Therefore, when an external force is applied to the fluid rectifier 14, the load applied from the fluid rectifier 14 to the stand 18 can be distributed between the support body 22 and the support member 58, preventing stress concentration on the stand 18, thereby suppressing damage to the stand 18 and reducing the strength of the stand 18.

[0051] Furthermore, the stand 18 supports the rectifying fluid 14 on the outside of the support 22 (outside in the vehicle width direction), and the support member 58 supports the stand 18 on the outside of the support 22 (outside in the vehicle width direction). Therefore, even when the stand 18 supports the rectifying fluid 14 on the outside of the support 22, the load acting from the rectifying fluid 14 on the stand 18 can be distributed between the support 22 and the support member 58.

[0052] Furthermore, the output gear 50 and clutch 52 are positioned on the outside (inward in the vehicle width direction) between the support position of the stand 18 by the support body 22 (position of the support cylinder 24B) and the support position of the support member 58 (position of the rotating cylinder 14B). As a result, the widthwise dimension of the arm 60 of the support member 58 can be reduced, the rigidity of the front vehicle portion of the arm 60 can be increased, and the support rigidity of the stand 18 by the support member 58 can be increased.

[0053] Furthermore, a coil spring 54 is positioned on the outside (inward in the vehicle width direction) between the support position of the stand 18 by the support body 22 (position of the support cylinder 24B) and the support position of the support member 58 (position of the rotating cylinder 14B). As a result, the widthwise dimension of the arm 60 of the support member 58 can be made even smaller, the rigidity of the front vehicle portion of the arm 60 can be made even higher, and the support rigidity of the stand 18 by the support member 58 can be made even higher.

[0054] Furthermore, the support shaft 64 of the support member 58 supports the outer end of the stand 18 in the vehicle width direction via the rotating cylinder 14B and connecting cylinder 14A of the rectifying fluid 14. Therefore, it is not necessary for the support member 58 to directly support the stand 18, and the degree of freedom in the configuration of the support member 58 can be greatly increased.

[0055] Furthermore, the cover 32 is fixed to the case 24, and the cover 32 covers the motor 42 of the case 24 and the motor base 28. This protects the motor 42.

[0056] In this embodiment, the arm 60 of the support member 58 is made into an L-shaped plate in cross-section and is fixed to the case 24 from the front side of the vehicle. However, the arm 60 of the support member 58 may also be made into a U-shaped plate in cross-section and fixed to the case 24 from the outside in the vehicle width direction.

[0057] Furthermore, in this embodiment, the rotating cylinder 14B of the fluid rectifier 14 is rotated relative to the support shaft 64 of the support member 58. However, the support shaft 64 of the support member 58 may rotate integrally with the rotating cylinder 14B of the fluid rectifier 14.

[0058] In this embodiment, the support member 58 supports the stand 18 via the rectifying fluid 14. However, the support member 58 may also directly support the stand 18. [Explanation of symbols]
