Description

  The present invention relates to a front rectifying structure for an automobile having a shutter unit for controlling the flow of outside air flowing into an engine room from a grille opening formed at the front of the vehicle, for example.

The front part of the automobile is configured so that outside air is taken into the engine room through a grille opening formed in the bumper face, and a heat exchanger such as a radiator or an intercooler, and the engine can be cooled.
Furthermore, in recent years, an automobile equipped with a shutter unit that controls the flow of outside air flowing in from the grille opening is known in order to further improve fuel consumption and reduce exhaust gas (see Patent Document 1 and Patent Document 2). ).

  This shutter unit includes a plurality of flaps that open and close according to the temperature of lubricating oil circulating in the engine, the temperature of cooling water, or the vehicle speed. For example, the shutter unit can inhibit the supply of outside air to the heat exchanger and the engine by closing the flap. Thereby, lubricating oil and cooling water can be raised to desired temperature at an early stage, and so-called fuel consumption deterioration accompanying warm-up operation is suppressed.

  Alternatively, by opening and closing the flap according to the vehicle speed, the shutter unit suppresses the flow of outside air into the engine room, and the outside air that flows down from the engine room to the rear of the vehicle and the traveling wind that flows down the side of the vehicle The generation of turbulence due to the merging of the two can be suppressed. As a result, an increase in running resistance due to turbulent flow is suppressed to improve fuel consumption and reduce exhaust gas.

  As such a shutter unit, for example, Patent Document 1 discloses a wind guide member (duct portions 21 and 22) that guides outside air flowing in from grill opening portions (air intake ports 13a and 13a), and a wind guide member. A duct device 10 having flaps (shutters 23 and 43) supported so as to be swingable inside, and drive mechanism portions (drive devices 36 and 37) which are disposed outside the air guide member and drive the flaps to open and close. It is disclosed.

  In the case of the shutter unit configured as in Patent Document 1, when the hot air heated by the engine circulates due to the pressure of the radiator fan or the like and returns to the front of the vehicle, the drive mechanism is exposed to the hot air. For this reason, when the temperature of the drive mechanism part exceeds the range where it operates stably, there is a possibility that the operation of the shutter unit may be defective.

  Therefore, for example, as in the shutter unit (grill shutter device 10) of Patent Document 2, the drive mechanism unit (actuator 18) is arranged at the approximate center in the vehicle width direction, that is, inside the air guide member of Patent Document 1. By disposing the drive mechanism portion in the vehicle, it is possible to protect the drive mechanism portion from the hot air recirculating through the front portion of the vehicle.

  However, if the drive mechanism portion is arranged inside the air guide member, when the flap is opened, the drive mechanism portion becomes a resistance and the outside air does not flow smoothly to the rear of the vehicle, or the opening area through which the outside air passes becomes small. There is a possibility that the external air having a desired flow rate may not be supplied to the heat exchanger.

  In view of the above problems, the present invention provides an automotive front rectification structure capable of preventing a malfunction of a drive mechanism portion due to hot air that circulates through the front of the vehicle without hindering the flow of outside air passing through the shutter unit. With the goal.

  The present invention provides an openable / closable shutter unit disposed on the vehicle upper side with respect to a bumper reinforcement at the front of the vehicle, an opening formed in a bumper face disposed in front of the vehicle relative to the shutter unit, and opposed to the shutter unit. A front rectifying structure for an automobile comprising a grill opening that conducts and a wind guide member that guides air from the grill opening to the shutter unit, and a flap that is supported by the shutter unit so as to be openable and closable. A shutter frame portion that integrally surrounds the flap, and a drive mechanism portion that is provided on an outer peripheral surface of the shutter frame portion and that drives the flap to open and close. And the drive mechanism portion is integrally formed.

The shutter unit may have a configuration in which flat flaps are juxtaposed in the vehicle vertical direction, or a configuration in which flat flaps are juxtaposed in the vehicle width direction.
The drive mechanism section can be a link mechanism coupled to a flap, a gear, and a drive motor that drives the gear and the link, and can be disposed on the side surface, the upper surface, or the lower surface of the shutter frame portion.
The air guide member can be made of synthetic resin or metal, and can be, for example, a substantially U-shaped air guide member in front view with the vehicle upper side opened. Alternatively, a cylindrical body having a substantially rectangular shape in front view can be used.

According to the present invention, it is possible to prevent a problem of the drive mechanism portion due to the hot air flowing back through the front portion of the vehicle without hindering the flow of outside air passing through the shutter unit.
Specifically, since the drive mechanism portion is arranged on the outer peripheral surface of the shutter frame portion, the shutter unit has a shutter with the flap opened compared to the case where the drive mechanism portion is arranged inside the shutter frame portion. The opening area of the frame portion can be ensured with a desired size.

  Since the shutter frame portion and the drive mechanism portion are formed so as to integrally surround the air guide member, the outside air flowing in from the grill opening can be guided to the drive mechanism portion. For this reason, the front flow straightening structure of the automobile can always cool the drive mechanism portion disposed on the outer peripheral surface of the shutter frame portion regardless of the open / closed state of the flap.

  Furthermore, the hot air that recirculates through the front of the vehicle is more likely to flow upwards of the vehicle due to the outside air flowing in from the grill opening. For this reason, for example, even in the case of a substantially U-shaped air guide member that is open at the top of the vehicle, the air guide member is configured so that the hot air that circulates through the front of the vehicle flows from the side of the air guide member to the inside. Inflow can be prevented.

  As a result, the front rectifying structure of the automobile can prevent the drive mechanism portion from being exposed to the hot air flowing back through the front of the vehicle, even if the front-side rectifying structure is a substantially U-shaped air guide member that opens at the top of the vehicle. .

  Therefore, the front rectification structure of the automobile can prevent the front part of the vehicle from being disturbed by the air guide member that integrally surrounds the drive mechanism part disposed on the outer peripheral surface of the shutter frame part without inhibiting the flow of outside air passing through the shutter unit. It is possible to prevent a malfunction of the drive mechanism due to the hot air that flows back.

  As an aspect of the present invention, the shutter unit can be arranged to face the grill opening in the vehicle front-rear direction and to have a size that can face the opening within the grill opening.

According to the present invention, the front rectifying structure of the automobile can cool the drive mechanism part more stably without hindering the flow of outside air passing through the shutter unit.
Specifically, by forming the shutter unit in a size that can be opposed within the opening range of the grill opening, the drive mechanism can reliably face the grill opening.

  Further, the airflow guide member that integrally surrounds the shutter frame portion and the drive mechanism portion enables the front rectifying structure of the automobile to more stably guide the outside air flowing in through the grill opening to the drive mechanism portion. be able to.

  In addition, when the area of the shutter frame portion in the front view is smaller than the opening area of the grill opening portion in the front view, the shutter unit can prevent the flow rate of the outside air passing through the shutter frame portion from decreasing.

For this reason, the front rectification structure of an automobile can reliably supply outside air to, for example, a heat exchanger disposed behind the shutter unit relative to the shutter unit.
Therefore, the front rectifying structure of the automobile has the shutter unit formed in a size that can be opposed within the opening range of the grill opening, so that the drive mechanism portion can be installed without hindering the flow of outside air that passes through the shutter unit. Cooling can be performed more stably.

  Further, as an aspect of the present invention, the drive mechanism portion is provided at a side portion or a lower portion of the shutter frame portion, and the wind guide member is disposed close to the bumper reinforcement in the vehicle vertical direction, and is viewed from the front. Can be formed in a substantially U-shape when viewed from the front with the upper part of the vehicle open.

  According to the present invention, the front rectifying structure of the automobile can supply outside air to the rear of the vehicle rather than the shutter unit even if the flap remains closed, for example, heat damage in the engine room Can be suppressed.

  Specifically, for example, in the case of a substantially cylindrical air guide member that connects the grill opening and the shutter unit, in the unlikely event that the flap remains closed, the heat exchanger disposed behind the shutter unit Or outside air is not supplied to the engine. For this reason, the heat exchanger or the like cannot be cooled, and the hot air heated by the engine stays there, and there is a possibility that heat damage may occur in each component in the engine room.

  Therefore, by forming the air guide member in a substantially U-shape in front view with the upper part of the vehicle open, the air guide member receives the outside air flowing in through the grille opening in cooperation with the shutter unit with the flap closed. The vehicle can be supplied to the rear of the vehicle through the opening on the vehicle upper side.

  Thereby, even if the front rectifying structure of the automobile is in a state in which the flap remains closed, the hot air accumulated in the upper space behind the shutter unit can be blown to the rear of the vehicle. For this reason, the front rectifying structure of the automobile can suppress heat damage in the engine room even if the flap remains closed.

  Furthermore, when the flap is closed, the cooperation between the shutter unit and the air guide member allows the outside air flowing in from the grill opening to be directly applied to, for example, the heat exchanger or the engine disposed behind the shutter unit. It becomes difficult to be supplied to.

  For this reason, even if it is a substantially U-shaped wind guide member that opens from the front of the vehicle, the front rectifying structure of the automobile closes the flap, for example, to generate hot air that tends to accumulate in the upper space in the engine room. While blowing air to the rear of the vehicle, the cooling water and lubricating oil can be raised to a desired temperature at an early stage.

  Therefore, the front rectifying structure of the automobile has a substantially U-shaped air guide member that is open at the top of the vehicle, so that even if the flap remains closed, the outside air is more rearward than the shutter unit. For example, heat damage in the engine room can be suppressed.

  Further, as an aspect of the present invention, a predetermined electronic device that detects the front of the vehicle from the bumper face is provided at a substantially center in the vehicle width direction in front of the shutter unit from the shutter unit, and the drive mechanism unit includes the shutter frame unit. Can be placed on the sides of

  The predetermined electronic device can be, for example, a sensor for identifying a vehicle or an obstacle ahead, a millimeter wave radar or a microwave radar as a sensor for measuring a distance from the vehicle or obstacle ahead. Or it can be set as the camera etc. which image the front.

  According to the present invention, the front rectifying structure of the automobile can suppress the occurrence of a problem in the predetermined electronic device due to electromagnetic noise generated by the drive mechanism when the predetermined electronic device is arranged in front of the shutter unit.

  Specifically, for example, when the drive motor is provided in the drive mechanism unit, the drive mechanism unit may generate electromagnetic noise as the drive motor rotates. For this reason, the closer the drive mechanism unit and the predetermined electronic device are, the more easily the predetermined electronic device is affected by electromagnetic noise, which may cause erroneous detection of the state in front of the vehicle.

  Therefore, the predetermined electronic device can be separated from the drive mechanism portion by providing the predetermined electronic device substantially at the center in the vehicle width direction and disposing the drive mechanism portion outside the vehicle width direction in the shutter frame portion. It becomes difficult to be influenced by electromagnetic noise generated by the drive mechanism.

  Therefore, the front rectifying structure of the automobile includes a predetermined electronic device substantially at the center in the vehicle width direction, and the drive mechanism portion is arranged on the side of the shutter frame portion, so that the predetermined noise is generated by the electromagnetic noise generated by the drive mechanism portion. It is possible to suppress the occurrence of defects in the electronic equipment.

  Further, as an aspect of the present invention, a heat generating device desired to be cooled is provided on the vehicle upper side of the shutter unit, and the heat generating device is provided on the air guide member above the drive mechanism portion of the shutter unit. A communication path communicating with the vicinity can be provided.

The vehicle upper side with respect to the shutter unit refers to a position offset in the vehicle width direction above the shutter unit or above the shutter unit.
The heat generating device can be, for example, a headlight unit configured with a headlamp, or a headlight unit configured with a headlamp, a vehicle width lamp, or the like.
For example, the communication path may be a communication path formed by cutting out an upper portion of a substantially U-shaped air guide member that is open on the vehicle upper side. Alternatively, a side passage in the air guide member having a substantially rectangular shape when viewed from the front, or a communication passage in which a part of the upper portion is formed to be open can be used.

According to the present invention, the front rectifying structure of an automobile can supply outside air to the heat generating device and can prevent the drive mechanism portion from being exposed to the hot air heated by the heat generating device.
Specifically, a heat-generating device that generates heat by operation, such as an LED headlamp, may be arranged above the shutter unit in the vehicle. Such a heat generating device requires forced cooling for protection of a built-in circuit board and the like and stable operation.

  However, for example, when the heat generating device is arranged at a position above the shutter unit and offset to the outside in the vehicle width direction from the shutter unit, depending on the length of the wind guide member in the vehicle vertical direction, the air flowed from the grille opening. Outside air may not be supplied to the heat generating device.

  Therefore, by providing the communication path in the wind guide member, the wind guide member can guide the outside air flowing in from the grill opening to the drive mechanism and the heat generating device. At this time, since the air guide member can guide the outside air to the heat generating device regardless of the open / closed state of the flap, the heat generating device desired to be cooled can be stably cooled.

  Furthermore, since the communication path is provided above the vehicle from the drive mechanism, the air guide member can prevent the hot air heated by the heat generating device from flowing into the internal space of the air guide member.

  Therefore, the front rectifying structure of the automobile can supply outside air to the heat generating device regardless of the open / closed state of the flap by the communication path above the vehicle than the drive mechanism portion, and the drive mechanism portion to the hot air heated by the heat generating device. Can be prevented from being exposed.

  According to the present invention, it is possible to provide a front rectification structure for an automobile that can prevent a malfunction of a drive mechanism portion due to hot air that circulates through the front of the vehicle without hindering the flow of outside air that passes through the shutter unit.

The third fixing portion 65 is formed with a bolt insertion hole 65a through which a fastening bolt 31 that is screwed into a screw hole 26a provided in the lower portion of the stay member 26 is inserted.

  As shown in FIGS. 3 and 8, the air guide member 60 having such a configuration includes upper and lower front surfaces in the outer edge portion 622, rear and lower surfaces in the inner edge portion 623, and a rear surface in the front wall portion 613. In addition, a substantially prismatic sponge 66 having elasticity is attached to the lower surface of the lower surface portion 612.

Sponges 66 affixed to the upper and lower front surfaces of the outer edge portion 622 are disposed so as to contact the rear surface of the bumper face 5 in a state where the air guide member 60 is mounted on the vehicle front portion 2.
The sponge 66 affixed to the rear surface of the inner edge portion 623 is disposed so as to contact the side mounting portion 535 of the shutter unit 50 in a state where the air guide member 60 is mounted on the vehicle front portion 2.
The sponge 66 affixed to the lower surface of the inner edge portion 623, the rear surface of the front wall portion 613, and the lower surface of the lower step surface portion 612 is disposed so as to contact the bumper reinforcement 24.

Next, in the vehicle front portion 2 having the above-described configuration, the flow of the outside air W flowing from the upper grill opening 10 will be described in detail with reference to FIGS. 9 and 10.
FIG. 9 is an explanatory diagram illustrating the flow of the outside air W when the flap 51 is open, and FIG. 10 is an explanatory diagram illustrating the flow of the outside air W when the flap 51 is closed.

  First, when the flap 51 is open, the outside air W flowing in from the upper grill opening 10 passes through the periphery of the horn 41 and the flap 51 of the shutter unit 50 as shown in FIG. The air flows down from the 28 air guide paths 28a toward the rear of the vehicle.

  On the other hand, when the flap 51 is in a closed state, the outside air W flowing in from the lower portion of the upper grill opening 10 is inhibited from flowing toward the rear of the vehicle by the flap 51 as shown in FIG. For this reason, the outside air W flowing in from the lower part of the upper grill opening 10 is deflected upward by the shutter unit 50.

  Thereafter, the outside air W deflected upward of the vehicle flows upward of the vehicle through the opening of the wind guide member 60 and the wind guide opening 60a, and flows upward from the upper grill opening 10 toward the rear of the vehicle. It merges with the outside air W that flows down and flows down to the rear of the vehicle.

  At this time, the outside air W passing through the air guide opening 60a flows toward the lamp housing 8a of the headlight unit 8, and then joins the outside air W flowing down from the upper part of the upper grill opening 10 toward the rear of the vehicle. Flow downwards.

  The outside air W passes through the periphery of the horn 41 and the air guide path 28 a of the shroud member 28, passes through the upper portion of the radiator 43, and then flows down along the lower surface of the bonnet 6. That is, when the flap 51 is in a closed state, the outside air W that has flowed from the upper grill opening 10 flows downward through the upper portion inside the vehicle front portion 2.

  The front rectification structure of the automobile 1 configured to realize the flow of the outside air W as described above does not hinder the flow of the outside air W passing through the shutter unit 50, and the actuator 54 is heated by the hot air flowing back through the vehicle front portion 2. Problems can be prevented.

  Specifically, since the actuator 54 is disposed on the outer peripheral surface of the shutter frame member 53, the shutter unit 50 is in a state in which the flap 51 is opened compared to the case where the actuator 54 is disposed inside the shutter frame member 53. The opening area of the shutter frame member 53 can be ensured with a desired size.

  Since the shutter frame member 53 and the actuator 54 are formed so as to integrally surround the air guide member 60, the outside air W flowing from the upper grill opening 10 can be guided to the actuator 54. For this reason, the front rectifying structure of the automobile 1 can always cool the actuator 54 disposed on the side surface of the shutter frame member 53 regardless of the open / closed state of the flap 51.

  Further, the hot air flowing back through the vehicle front portion 2 is more easily flowed upward of the vehicle by the outside air flowing in from the upper grill opening 10. For this reason, the air guide member 60 can prevent the hot air flowing back through the vehicle front portion 2 from flowing into the inside from the side of the air guide member 60.

  As a result, the front rectifying structure of the automobile 1 is configured such that the actuator 54 is exposed to the hot air flowing back through the front part 2 of the vehicle, even if the air guide member 60 is substantially U-shaped when viewed from the front. Can be prevented.

  Therefore, the front flow straightening structure of the automobile 1 is not obstructed by the air guide member 60 that integrally surrounds the actuator 54 disposed on the outer peripheral surface of the shutter frame member 53 without hindering the flow of the outside air W that passes through the shutter unit 50. It is possible to prevent the malfunction of the actuator 54 due to the hot air flowing back through the vehicle front portion 2.

  Further, the front unit of the automobile 1 is formed by arranging the shutter unit 50 so as to be opposed to the upper grill opening 10 in the longitudinal direction of the vehicle and to be opposed to the upper grill opening 10 within the opening range. The rectifying structure can cool the actuator 54 more stably without hindering the flow of the outside air W passing through the shutter unit 50.

  Specifically, by forming the shutter unit 50 in such a size that it can face within the opening range of the upper grill opening 10, the actuator 54 can reliably face the upper grill opening 10.

  Further, the airflow guide member 60 that integrally surrounds the shutter frame member 53 and the actuator 54 allows the front rectification structure of the automobile 1 to more stably stabilize the outside air W that has flowed in through the upper grill opening 10. Can be guided to.

  In addition, since the area of the shutter frame member 53 in the front view is smaller than the opening area of the upper grill opening 10 in the front view, the shutter unit 50 has a lower flow rate of the outside air W passing through the shutter frame member 53. Can be prevented.

For this reason, the front rectification structure of the automobile 1 can reliably supply the outside air W to the radiator 43 and the like disposed behind the shutter unit 50.
Therefore, the front flow straightening structure of the automobile 1 prevents the flow of the outside air W passing through the shutter unit 50 by forming the shutter unit 50 in a size that can be opposed within the opening range of the upper grill opening 10. Therefore, the actuator 54 can be cooled more stably.

  In addition, by providing the actuator 54 on the right side surface portion 533 of the shutter frame member 53 and forming the air guide member 60 in a substantially U-shape when viewed from the front, the front rectifying structure of the automobile 1 is Even if the flap 51 remains closed, the outside air W can be supplied to the rear of the vehicle from the shutter unit 50, and for example, heat damage in the engine room can be suppressed.

  Specifically, for example, in the case of a substantially cylindrical air guide member that connects the upper grill opening 10 and the shutter unit 50, if the flap 51 remains closed, The outside air W is not supplied to the arranged radiator 43 and engine. For this reason, the radiator 43 and the like cannot be cooled, and the hot air warmed by the engine stays in the engine room, which may cause heat damage to each component.

  Therefore, the air guide member 60 is formed in a substantially U-shape in front view with the upper part of the vehicle open, so that the air guide member 60 can move the upper grille opening 10 in cooperation with the shutter unit 50 with the flap 51 closed. The outside air W that flows in through the vehicle can be supplied to the vehicle rear side through the opening on the vehicle upper side.

  Thereby, even if the front rectification structure of the automobile 1 is in a state where the flap 51 remains closed, the hot air accumulated in the upper space behind the shutter unit 50 can be blown to the rear of the vehicle. . For this reason, the front rectification structure of the automobile 1 can suppress heat damage in the engine room even if the flap 51 remains closed.

  Furthermore, when the flap 51 is in a closed state, the cooperation of the shutter unit 50 and the air guide member 60 makes it difficult for the outside air W flowing from the upper grill opening 10 to be directly supplied to the radiator 43 and the engine. Become.

  For this reason, even if the air guide member 60 is substantially U-shaped when viewed from the front, the front rectifying structure of the automobile 1 closes the flap 51 so that hot air is easily collected in the upper space in the engine room. The cooling water and the lubricating oil can be raised to a desired temperature at an early stage while blowing air to the rear of the vehicle.

  Therefore, the front rectifying structure of the automobile 1 is more than the shutter unit 50 even if the flap 51 remains closed due to the substantially U-shaped air guide member 60 opened from the front of the vehicle. The outside air W can be supplied to the rear of the vehicle, and for example, heat damage in the engine room can be suppressed.

  Further, the front member 42 is provided with the front radar 42 and the actuator 54 is disposed on the right side surface portion 533 of the shutter frame member 53, so that the front rectifying structure of the automobile 1 can It is possible to suppress the occurrence of defects.

  Specifically, when the drive motor is provided in the actuator 54, the actuator 54 may emit electromagnetic noise as the drive motor rotates. For this reason, the closer the actuator 54 and the front radar 42 are, the more easily the front radar 42 is affected by electromagnetic noise, and there is a possibility of erroneously detecting the state in front of the vehicle.

  Therefore, the stay member 26 includes the front radar 42, and the actuator 54 is disposed on the right side surface portion 533 of the shutter frame member 53, so that the front radar 42 can be separated from the actuator 54. It becomes difficult to be affected.

  Accordingly, the front rectifying structure of the automobile 1 includes the front radar 42 on the stay member 26 and the actuator 54 disposed on the right side surface portion 533 of the shutter frame member 53, so that electromagnetic noise generated by the actuator 54 causes the front radar 42 to It is possible to suppress the occurrence of defects.

  Further, by providing the wind guide member 60 with the wind guide opening 60 a communicating with the vicinity of the headlight unit 8, the front rectifying structure of the automobile 1 allows the headlight unit 8 to be connected to the outside air W regardless of the open / close state of the flap 51. In addition, it is possible to suppress the flow of hot air from the headlight unit 8 to the actuator 54.

  Specifically, for example, in the case of a headlight unit 8 that generates heat by operation, such as an LED lamp, the headlight unit 8 requires forced cooling for protection of a built-in circuit board and the like and stable operation. It becomes.

  Therefore, by providing the air guide member 60 with the air guide opening 60 a, the air guide member 60 can guide the outside air W flowing from the upper grill opening 10 to the actuator 54 and the headlight unit 8. .

  At this time, since the air guide member 60 can guide the outside air W to the headlight unit 8 regardless of the open / closed state of the flap 51, the headlight unit 8 that is desired to be cooled can be stably cooled.

  Furthermore, since the air guide opening 60 a is provided above the vehicle from the actuator 54, the air guide member 60 can prevent the hot air from the headlight unit 8 from flowing into the internal space of the air guide member 60.

  Therefore, the front rectifying structure of the automobile 1 can supply the outside air W to the headlight unit 8 regardless of the open / closed state of the flap 51 by the wind guide opening 60 a above the actuator 54 and the headlight unit 8. The actuator 54 can be prevented from being exposed to the heated hot air.

  Further, by connecting the third fixing portion 65 of the air guide member 60 and the stay member 26, the front rectifying structure of the automobile 1 directly places the air guide member 60 in the center of the shutter frame member 53 in the vehicle width direction. Therefore, the plurality of flaps 51 can be rotated more stably than in the case where they are connected together.

  Specifically, for example, when the air guide member 60 is directly connected to the center of the bottom plate portion 532 of the shutter frame member 53 in the vehicle width direction, the lower surface portion due to the pressure variation of the outside air W flowing from the upper grill opening 10. When the vibration 61 is transmitted through the bottom plate portion 532 having low rigidity, the shutter frame member 53 may be distorted by vibration.

  For this reason, for example, in the case of a configuration in which the plurality of flaps 51 are rotated by the link mechanism supported by the shutter frame member 53, an increase in sliding resistance or an axial deviation occurs due to the distortion of the shutter frame member 53, There is a possibility that the operation of the link mechanism is hindered.

  In particular, the link mechanism that rotates the plurality of flaps 51 is more likely to be complicated in structure than the link mechanism that rotates a single flap, and thus is easily affected by the distortion of the shutter frame member 53.

  Therefore, by connecting the third fixing portion 65 of the air guide member 60 and the stay member 26, the front rectifying structure of the automobile 1 can transmit the vibration of the air guide member 60 to the stay member 26. Vibration transmission to the shutter frame member 53 can be suppressed.

  Thereby, the front part rectification | straightening structure of the motor vehicle 1 can suppress the distortion of the shutter frame member 53 by vibration.
