  As shown in FIGS. 2 and 3, the bumper louver 3 includes a frame body 30 extending in the vehicle body width direction in the bumper opening 20, and extending in the vehicle body width direction in the frame body 30. 7 and a shielding member 32 that opens or closes the bumper opening 20 by alternately repeating the vertical and horizontal movements by the rotation of the rotary shaft 31.

The frame body 30 is formed in a substantially rectangular shape along the inner peripheral surface of the bumper opening 20, and has two spaces partitioned in the middle in the vehicle body width direction by an intermediate member 30a.
The frame body 30 has an upper surface and a lower surface on the outside fixed to the inner surface of the bumper opening 20. The inside of the frame 30 becomes an air flow path through which outside air passes when the bumper louver 3 is opened.

The shielding member 32 is installed in two stages in the vertical direction in each space of the frame body 30.
The shielding member 32 is flat and extends in the vehicle width direction and is formed in a substantially rectangular shape. The rotating shaft 31 is provided in the vehicle width direction from a substantially central portion in the short direction. Both ends of the rotating shaft 31 are rotatably supported by the side surface of the frame 30 and the intermediate member 30a, and the shielding member 32 rotates as the rotating shaft 31 rotates.

  As shown in FIG. 3, when the shielding member 32 of the bumper louver 3 faces in the horizontal direction, the bumper opening 20 is fully opened, and an air passage through which traveling wind passes is formed. On the other hand, as shown in FIG. 2, when the shielding member 32 is oriented in the vertical direction, the bumper opening 20 is fully closed and the air passage is closed. In other words, the bumper opening 20 is opened or closed by the bumper louver 3 to adjust the amount of outside air that flows from the bumper opening 20 into the engine room.

The bumper louver 3 is controlled by a controller 70 so that the bumper opening 20 is opened or closed.
The means for driving the bumper louver 3 is an actuator 7 attached to the outer surface of the frame 30 as shown in FIG. The actuator 7 is an electric motor, and interlocks the upper and lower shielding members 32, 32 via a driving force reduction mechanism 73 in accordance with a command from the controller 70.

  The controller 70 has a CPU, a ROM, and a RAM. When the controller 70 receives an input signal from a device connected to the input side, the CPU reads a program stored in the ROM based on the input signal and stores a state detected by the input signal in the RAM. Or transmit an output signal to a device connected to the output side.

As shown in FIG. 4, a vehicle speed sensor 71 that detects the speed of the vehicle 1 is connected to the input side of the controller 70. The vehicle speed sensor 71 is, for example, a wheel speed sensor. A water temperature sensor 72 for measuring the water temperature of the radiator is connected to the input side of the controller 70.
On the other hand, an actuator 7 for opening or closing the bumper louver 3 is connected to the output side of the controller 70. Information regarding the cooling load is acquired by the vehicle speed sensor 71 and the water temperature sensor 72, and a signal is transmitted from the controller 70 to the actuator 7 based on this information.

  As shown in FIG. 2, an air dam 6 is provided at the bottom of the bumper 2 and at the front bottom of the vehicle 1. The air dam 6 protrudes from the inside of the bumper 2 to the lower side of the vehicle body and is inclined vertically or to the rear side of the vehicle so as to narrow an air flow path passing under the vehicle body in the engine room. The air dam 6 projects downward when it is necessary to suppress the inflow of air below the vehicle body according to an instruction from the controller 70, and is stored inside the bumper 2 when not necessary.

  The opening / closing of the bumper opening 20 by the bumper louver 3 and the storage / protrusion of the air dam 6 are (1) a state in which the bumper opening 3 is opened by the bumper louver 3 and the air dam 6 is stored. A state in which the bumper opening 20 is closed by the bumper louver 3 and the air dam 6 is retracted; and (3) a state in which the bumper opening 20 is opened by the bumper louver 3 and the air dam 6 is projected. The link mechanism 8 is used to switch the state where the bumper opening 20 is closed by the bumper louver 3 and the air dam 6 is projected by a single actuator 7.

  The link mechanism 8 is attached to the rotary shaft 31 of the bumper louver 3, and is linked with the rotary cam 80 that rotates together with the shielding member 32 by the actuator 7 by the rotation of the rotary cam 80. And a rocker arm 9 for alternately storing and projecting the air dam 6 every time.

  As shown in FIGS. 5A to 5D, the rotary cam 80 is configured in a substantially right triangle shape having two cam peaks having apexes at 90 ° phase shifted positions on the circumference. Has been. The rotary cam 80 has a right angled corner fixed to the rotating shaft 31 of the bumper louver 3, and the two cam peaks rotate in the circumferential direction as the rotating shaft 31 rotates.

  The rocker arm 9 includes a swing member 90 that changes between a horizontal state and an inclined state according to the rotational position of the cam crest of the rotary cam 80, and a connecting member 92 that connects the swing member 90 and the air dam 6. ing.

The oscillating member 90 has a fulcrum supported by a fixed shaft 90a supported by the frame 30, the force point side end 90b is in contact with the outer surface of the rotary cam 80, and the action point side end 90c is The upper end of the connecting member 92 is connected.
The oscillating member 90 changes to a horizontal state or an inclined state every time the rotating shaft 31 rotates about a half circumference with the fixed shaft 90a as a fulcrum.

The connecting member 92 has a lower end that penetrates the bumper 2 and is joined to an end of the air dam 6. The connecting member 92 can move in the vertical direction by the swinging of the swinging member 90.
An upper end portion of the connecting member 92 is provided with a flange 92 a that restricts the vertical movement of the connecting member 92. The vertical movement of the connecting member 92 is restricted when the flange 92a hits the inner surface of the bumper opening 20. Between the flange 92a and the inner surface of the bumper opening 20, an elastic member 94 such as a spring material that pushes the connecting member 92 moved downward is interposed.

  Next, the operation state of the movable member interlocking mechanism for a vehicle according to the first embodiment will be described with reference to FIGS. 5 (A) and 5 (B) are performed when the vehicle 1 is low speed, and FIGS. 5 (C) and 5 (D) are performed when the vehicle 1 is high speed. From the viewpoint of prevention, the optimum state is selected from FIGS. 5 (A) to 5 (D).

FIG. 5A shows a state where the bumper opening 20 is opened by the bumper louver 3 and the air dam 6 is stored inside the bumper 2.
When the engine load is large and it is necessary to cool the cooling water of the radiator and the refrigerant of the condenser of the air conditioner, the bumper opening 20 is rotated by rotating the shielding member 32 of the bumper louver 3 to a horizontal orientation. Open and let outside air flow into the engine compartment.
At this time, one cam crest of the rotary cam 80 is arranged to face downward, and the other cam crest is arranged to face the rear of the vehicle body. Then, the rocking member 90 of the rocker arm 9 is placed on the horizontal plane of the rotary cam 80 and kept in a horizontal state. Since the connecting member 92 is pushed upward by the elastic action of the spring member 94, the air dam 6 is stored inside the bumper 2.
As a result, since the bumper opening 20 is opened, the cooling performance is improved, but the air resistance is increased and the air resistance coefficient is increased. Further, since the air dam 6 is stored, the front lift coefficient is increased.

Next, FIG. 5B shows a state in which the bumper opening 20 is closed by the bumper louver 3 and the air dam 6 is stored inside the bumper 2.
In order to block the outside air flowing into the engine room, the bumper opening 20 is closed by rotating the shielding member 32 of the bumper louver 3 so as to be vertically oriented.
The rotation of the shielding member 32 causes the rotary cam 80 to rotate 90 degrees clockwise from the state shown in FIG. 5 (A), so that one of the cam peaks is directed downward and the other cam peak is Head forward. At this time, the rocking member 90 of the rocker arm 9 is placed on the horizontal surface of the rotary cam 80 and kept in a horizontal state. Since the connecting member 92 remains pushed upward by the elastic action of the spring material 94, the air dam 6 is stored inside the bumper 2.
As a result, since the bumper opening 20 is closed, the cooling performance is lowered, but the air resistance is reduced, the air resistance coefficient is reduced, and the front lift coefficient is further reduced.

Next, FIG. 5C shows a state where the bumper opening 20 is opened by the bumper louver 3 and the air dam 6 protrudes downward from the vehicle body.
In order to allow the outside air to flow into the engine room, the bumper opening 20 is opened by rotating the shielding member 32 of the bumper louver 3 so as to be horizontally oriented.
The rotation of the shielding member 32 causes the rotary cam 80 to rotate 90 degrees clockwise from the state shown in FIG. 5B, so that one of the cam peaks faces upward and the other cam peak. Turn to the front of the car. At this time, the force point side end portion 90b of the swing member 90 is pushed upward by the rotary cam 80 to be inclined, so that the action point side end portion 90c pushes down the connecting member 92 and the air dam 6 is moved to the vehicle body. Project downward.
As a result, the cooling performance is improved because the bumper opening 20 is opened. Moreover, although air resistance becomes large, since the air dam is protruded, an air resistance coefficient becomes small and also a front lift coefficient becomes small.

Next, FIG. 5D shows a state in which the bumper opening 20 is closed by the bumper louver 3 and the air dam 6 protrudes downward from the vehicle body.
In order to block the outside air flowing into the engine room, the bumper opening 20 is closed by rotating the shielding member 32 of the bumper louver 3 so as to be vertically oriented.
The rotation of the shielding member 32 causes the rotary cam 80 to rotate 90 degrees clockwise from the state shown in FIG. 5C, with one of the cam peaks facing upward and the other cam peak being Turn to the rear of the car. At this time, since the force point side end 90b is pushed upward by the rotary cam 80 and the swinging member 90 is in an inclined state, the action point side end 90c pushes down the connecting member 92 and causes the air dam 6 to move. Project downward in the car body.
As a result, since the bumper opening 20 is closed, the cooling performance is lowered. However, since the air dam is protruded, the air resistance becomes small, the air resistance coefficient becomes very small, and the front lift coefficient becomes very small.

  In the embodiment shown in FIGS. 5A to 5D, the air dam 6 protrudes downward from the vehicle body when the swinging member 90 is in the inclined state, but this is not restrictive. By disposing the rotary cam 80 between the operating point side end 90c of the swinging member 90 and the fixed shaft 90a, the air dam 6 is moved downward in the vehicle body when the swinging member 90 is in a horizontal state. It can also be implemented as a configuration in which it is projected and retracted when the rocking member 90 is in an inclined state.

  Next, an example of the operation of the movable member interlocking mechanism for a vehicle according to the first embodiment will be described from the flowchart shown in FIG.

  First, in step ST1, the controller 70 determines the vehicle speed of the vehicle 1 based on the speed information obtained from the vehicle speed sensor 71. Specifically, it is determined whether or not the vehicle speed is higher than 80 km / h. If the controller 70 determines that the vehicle speed is greater than 80 km / h, the process proceeds to step ST2. On the other hand, when the controller 70 determines that the vehicle speed is 80 km / h or less, the process proceeds to step ST5.

  In step ST2, the controller 70 determines the water temperature based on the temperature information obtained from the water temperature sensor 72 provided in the radiator. Specifically, it is determined whether or not the water temperature is greater than 95 degrees. If the controller 70 determines that the water temperature of the radiator is greater than 95 degrees, the process proceeds to step ST3. On the other hand, when the controller 70 determines that the water temperature is 95 degrees or less, the process proceeds to step ST4.

In step ST3, the actuator 7 that has received the signal from the controller 70 is driven to rotate the shielding member 32 of the bumper louver 3 in the horizontal direction to open the bumper opening 20 and the air dam 6 to the vehicle body. (See FIG. 5C).
In step ST4, the actuator 7 that receives the signal from the controller 70 is driven to rotate the shielding member 32 of the bumper louver 3 in the vertical direction to close the bumper opening 20, and the air dam 6 is connected to the vehicle body. Project downward (see FIG. 5D).

  In step ST5, when the controller 70 determines in step ST1 that the vehicle speed is 80 km / h or less, the controller 70 determines the water temperature based on the temperature information obtained from the water temperature sensor 72 provided in the radiator. Specifically, it is determined whether or not the water temperature is greater than 95 degrees. If the controller 70 determines that the water temperature of the radiator is greater than 95 degrees, the process proceeds to step ST6. On the other hand, when the controller 70 determines that the water temperature is 95 degrees or less, the process proceeds to step ST7.

In step ST6, the actuator 7 that has received the signal from the controller 70 is driven to rotate the shielding member 32 of the bumper louver 3 in the horizontal direction to open the bumper opening 20, and the air dam 6 is moved into the bumper 2. Store (see FIG. 5A).
In step ST7, the actuator 7 that has received a signal from the controller 70 is driven to rotate the shielding member 32 of the bumper louver 3 in the vertical direction to close the bumper opening 20 and to move the air dam 6 to the inside of the bumper 2. (See FIG. 5B).
The vehicle speed of the vehicle 1 and the water temperature of the radiator are not limited to the above values. Depending on the performance of the vehicle 1 and the like, various numerical values are used.

  Therefore, the movable member interlocking mechanism of the vehicle according to the first embodiment can switch the opening / closing of the bumper opening 20 and the storage / protrusion of the air dam 6 to four patterns by the link mechanism 8 with the single actuator 7. Therefore, the installation cost of the actuator 7 can be reduced, which is economical. Further, it is possible to achieve both improvement in fuel consumption by opening and closing the bumper opening 20 and stability of high-speed traveling by storing and storing the air dam 6.

(Second Embodiment)
Next, a second embodiment of the vehicle movable member interlocking mechanism according to the present invention will be described with reference to FIGS.

As shown in FIG. 1, the grill 4 disposed on the upper side of the front portion of the vehicle is formed between the bumper 2 and the front end of the hood 10 and has a decorative opening and a grill opening that allows air to pass through the engine room. 40 is formed.
As shown in FIG. 7, the grill opening 40 is provided with a grill louver 5 that adjusts the flow rate of outside air flowing into the engine room between the grill 4 and the radiator.

The configuration of the grill louver 5 is the same as that of the bumper louver 3 described in the paragraph numbers [0033] to [0036].
That is, as shown in FIGS. 3 and 7, when the shielding member 52 of the grill louver 5 is oriented in the horizontal direction, the grill opening 40 is fully opened, thereby providing an air passage through which outside air passes. On the other hand, when the shielding member 52 is oriented in the vertical direction, the grill opening 40 is fully closed and the air passage is closed. That is, the grill louver 5 opens or closes the grill opening 40 to adjust the amount of outside air introduced from the grill opening 40 into the engine room.

  The grill louver 5 is controlled by a controller to open or close the grill opening 40. The means for driving the grill louver 5 is an actuator attached to the outer surface of the frame 50. The actuator is an electric motor, and interlocks the upper and lower shielding members 52 via a drive force reduction mechanism 73 (see, for example, FIG. 2) in response to a command from the controller. The control means is the same as that described in the paragraph numbers [0037] to [0039], and a description thereof will be omitted.

  As shown in FIG. 2, an air dam 6 is provided at the front bottom portion of the vehicle 1. The air dam 6 projects downward when it is necessary to suppress the inflow of air below the vehicle body, and is stored inside the bumper 2 when it is not necessary, according to instructions from the controller.

  The opening and closing of the grill opening 40 by the grill louver 5 and the storing / protruding of the air dam 6 include (1) a state in which the grill opening 40 is opened and the air dam 6 is stored, and (2) the grill opening 40. And (3) opening the grill opening 40 and projecting the air dam 6, and (4) closing the grill opening 40 and closing the air dam 6. The four patterns in the protruding state are performed by the link mechanism 8 that switches with a single actuator.

  The structure of the link mechanism 8 is the same as that of the first embodiment described in the paragraph numbers [0042] to [0046]. That is, the operation state of the movable member interlocking mechanism of the vehicle according to the second embodiment is also the same as the configuration described based on FIGS.

  Therefore, the movable member interlocking mechanism of the vehicle according to the second embodiment can switch the opening / closing of the grill opening 40 and the storage / projection of the air dam 6 into four patterns by the link mechanism 8 with a single actuator.

It consists of
Note that the detailed description of the constituent members of the bumper louver 3 and the grill louver 5 is the same as the contents described in the paragraph numbers [0033] to [0036] of the first embodiment, and therefore will be omitted.

  The link mechanism 8 ′ is attached to the rotary shaft 31 of the bumper louver 3, and is linked with the rotary cam 80 that rotates with the shielding member 32 by the rotary shaft 31, and the rotary shaft 31 is rotated. A rocker arm 9 is provided that causes the shielding member 52 of the grill louver 5 to alternately perform vertical and horizontal movements each time it rotates half a circle.

  As shown in FIGS. 8A to 8D, the rotary cam 80 is configured in a substantially right triangle shape having two cam peaks having apexes at 90 ° phase shifted positions on the circumference. Has been. The rotary cam 80 has a right angled corner fixed to the rotating shaft 31 of the bumper louver 3, and the two cam peaks rotate in the circumferential direction as the rotating shaft 31 rotates.

  The rocker arm 9 includes a swinging member 90 that changes between a horizontal state and an inclined state according to the rotational position of the cam crest of the rotary cam 80, a switching member 93 that switches the grill louver 5 between a vertical direction and a horizontal direction, and the swinging member 90 and a connecting member 92 that connects the switching member 93 to each other.

The swing member 90 has a fulcrum supported by a side surface of the frame 30 of the bumper louver 3 and a fixed shaft 90a supported at both ends by the intermediate member 30a, and a force point side end portion 90b is an outer surface of the rotary cam 80. The action point side end portion 90c is connected to one end of the connecting member 92.
The oscillating member 90 changes to a horizontal state or an inclined state every time the rotating shaft 31 rotates about a half circumference with the fixed shaft 90a as a fulcrum.

  The switching members 93 are respectively attached to the rotation shafts 51 of the grill louvers 5 disposed above and below, and the respective leading end portions are attached to the other ends of the connecting members 92. In the case of the illustrated example, when the switching member 93 is turned upward, the shielding member 52 of the upper and lower grill louvers 5 is horizontally oriented, and the grill opening 40 is closed. On the other hand, when the switching member 93 is directed downward, the shielding member 52 of the upper and lower grill louvers 5 is oriented vertically, and the grill opening 40 is opened.

  The connecting member 92 has a rod shape as an example, and penetrates the bumper 2 to connect the swinging member 90 and each switching member 93. An elastic member 94 such as a spring material that comes into contact with the inner surface of the bumper 2 is attached to an intermediate portion located inside the bumper 2 of the connecting member 92.

Next, the operation state of the movable member interlocking mechanism for a vehicle according to the third embodiment will be described with reference to FIGS. From the reduction of the cooling performance and running resistance, the optimum state is selected from FIGS.
Incidentally, in the embodiment shown in FIGS. 8A to 8D, the bumper opening 20 is formed larger than the grill opening 40.

FIG. 8A shows a state in which the bumper opening 20 is opened and the grill opening 40 is opened.
When the engine load is large and it is necessary to cool the cooling water of the radiator and the refrigerant of the condenser of the air conditioner, the bumper opening 20 is opened by rotating the shielding member 32 of the bumper louver 3 to a horizontal orientation. .
In this case, one of the cam ridges of the rotary cam 80 is arranged to face downward, and the other cam hill is arranged to face rearward of the vehicle body. The rocking member 90 of the rocker arm 9 is placed on the horizontal surface of the rotary cam and becomes horizontal. Since the switching member 93 faces upward due to the elastic action of the spring material 94, the shielding member 52 of the grill louver 5 is disposed horizontally and the grill opening 40 is opened.
As a result, since the bumper opening 20 is opened and the grill opening 40 is also opened, the cooling performance is greatly improved, but the air resistance becomes very large and the air resistance coefficient becomes very large, Furthermore, the front lift coefficient becomes very large.

FIG. 8B shows a state in which the bumper opening 20 is closed and the grill opening 40 is opened.
In order to introduce the outside air flowing into the engine room only from the grill opening 40, the bumper opening 20 is closed by rotating the shielding member 32 of the bumper louver 3 so as to face vertically.
As the shielding member 32 of the bumper louver 3 rotates, the rotary cam 80 rotates 90 degrees clockwise from the state shown in FIG. The cam mountain faces the front of the car. At this time, the swinging member 90 of the rocker arm 9 is maintained in a horizontal state with the force point side end portion 90b placed on the horizontal surface of the rotary cam 80. Since the switching member 93 remains inclined upward due to the elastic action of the spring material 94, the shielding member 52 of the grill louver 5 remains horizontally and the grill opening 40 is opened.
As a result, since the bumper opening 20 is closed and the grill opening 40 is opened, the cooling performance is slightly reduced, the front lift coefficient is reduced, the air resistance is reduced, and the air resistance coefficient is reduced. .

FIG. 8C shows a state in which the bumper opening 20 is opened and the grill opening 40 is closed.
In order to introduce the outside air flowing into the engine room only from the bumper opening 20, the bumper opening 20 is opened by rotating the shielding member 32 of the bumper louver 3 so as to face horizontally.
Since the rotary cam 80 rotates 90 degrees clockwise from the state shown in FIG. 8B by the rotation of the shielding member 32 of the bumper louver 3, one of the cam peaks of the rotary cam 80 moves upward. Orientation, the other cam mountain faces the front of the car. Since the force point side end portion 90b of the rocker arm 9 is pushed upward by the cam crest of the rotary cam 80 to be inclined, the action point side end portion 90c is lowered downward to turn the switching member 93 downward. As a result, the shielding member 52 of the grill louver 5 faces vertically, so that the grill opening 40 is closed.
As a result, since the bumper opening 20 is opened and the grill opening 40 is closed, the front lift coefficient is reduced, but the cooling performance is slightly reduced, the air resistance is reduced, and the air resistance coefficient is reduced. Become.

FIG. 8D shows a state in which the bumper opening 20 is closed and the grill opening 40 is closed.
In order to completely shut off the outside air flowing into the engine room, the bumper opening 20 is closed by rotating the shielding member 32 of the bumper louver 3 so as to be vertically oriented.
As the shielding member 32 of the bumper louver 3 rotates, the rotary cam 80 rotates 90 degrees clockwise from the state shown in FIG. 8C, so that one of the cam peaks of the rotary cam 80 moves upward. Direction, the other cam mountain is facing the rear of the car body. Since the force point side end portion 90b of the rocker arm 9 is pushed upward by the cam crest of the rotary cam 80 and remains in an inclined state, the shielding member 52 of the grill louver 5 faces vertically and the grill opening 40 is closed. Is done.
As a result, since the bumper opening 20 is closed and the grill opening 40 is closed, the cooling performance is lowered. However, the air resistance becomes very small, the air resistance coefficient becomes very small, and the front lift coefficient becomes very small.

  Therefore, in the movable member interlocking mechanism for a vehicle according to the third embodiment, the opening and closing of the bumper opening 20 and the opening and closing of the grill opening 40 are made into four patterns by the single actuator 7 by the link mechanism 8 ′. Since it can be switched, the installation cost of the actuator 7 can be reduced, which is economical. Further, fuel consumption can be improved by opening / closing the bumper opening 20 and opening / closing the grill opening 40.

  Further, various opening ratios can be realized by changing the design of the opening area of the bumper opening 20 and the opening area of the grill opening 40 to various dimensions. For example, when the ratio of the opening area of the bumper opening 20 to the opening area of the grill opening 40 is set at 7: 3, the opening ratio is reduced when the bumper opening 20 is opened and the grill opening 40 is closed. Is 70%. On the other hand, when the bumper opening 20 is closed and the grill opening 40 is opened, the opening ratio becomes 30%. Therefore, since the opening ratio of the bumper opening 20 and the grill opening 40 can be finely changed by the single actuator 7 according to the cooling performance and the air resistance, it greatly contributes to the improvement of the fuel consumption and the high speed stability. Can do.

(Fourth embodiment)
Next, a fourth embodiment of the vehicle movable member interlocking mechanism according to the present invention will be described with reference to FIG.
In short, the movable member interlocking mechanism for a vehicle according to the fourth embodiment is a configuration obtained by reversing the configuration of the movable member interlocking mechanism for a vehicle according to the third embodiment.

  That is, the link mechanism 8 ′ is attached to the rotary shaft 51 of the grill louver 5, and is linked to the rotary cam 80 that rotates together with the shielding member 52 by the rotary shaft 51, by the rotation of the rotary cam 80. Each time 51 rotates half a circle, the shield member 32 of the bumper louver 3 is provided with a rocker arm 9 that alternately performs vertical and horizontal operations.

  By driving the actuator, the shielding member 52 of the grill louver 5 is rotated vertically or horizontally to open or close the grill opening 40 and rotate the rotary cam 80, whereby the rocker arm 9 causes the bumper louver 3 to rotate. The shielding member 32 is rotated vertically or horizontally to open or close the bumper opening 20.

  Therefore, since the movable member interlocking mechanism of the vehicle according to the fourth embodiment can switch the opening / closing of the bumper opening 20 and the opening / closing of the grill opening 40 into four patterns with the single actuator 7. Installation cost can be reduced and it is economical. Further, it is possible to achieve both improvement in fuel consumption by the single actuator 7 and stability of high-speed traveling by opening and closing the bumper opening 20 and opening and closing of the grill opening 40.

  Although the movable member interlocking mechanism of the vehicle according to the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the illustrated examples, and those skilled in the art are within the scope of the technical idea. I will add a note to cover the range of variations of design changes, modifications, and applications that are usually performed.

For example, the rotary cam 80 is not limited to being fixed to the rotating shaft 31. Although illustration is omitted in detail, for example, the rotary cam 80 may have a configuration in which a gear that rotates together with the rotation of the rotation shaft 31 of the bumper louver 3 is provided and rotated by the rotation of the gear. In this case, the rotary cam 80 can freely adjust the rotation angle by engaging a plurality of gears and changing the gear ratio.
Further, the rotary cam 80 can also be implemented by a configuration in which a pulley and a belt rotating with the rotation of the rotary shaft 31 of the bumper louver 3 are connected by a belt. In this case, the rotational angle of the rotary cam 80 can be freely adjusted by changing the size of the pulley.
