を防ぐことができる。In the description of the first embodiment, the air damper 2 corresponds to an outside air shutoff device, and the gear 3, the drive rod 4, and the solenoid valve 5 correspond to a drive device. However, in the first embodiment of the present invention, the outside air shutoff device is not limited to the air damper 2 and the drive device is not limited to the gear 3, the drive rod 4, and the solenoid valve 5. A slide-type shielding plate or the like can be used as the outside air blocking device, and the driving device can be configured by a motor and other mechanical parts. Further, as the switch 8 in the first embodiment of the present invention, a type that repeats the state of "open" and "shut off" each time it is pressed is used, but the switch piece is set to the "on" and "off" positions. That is, a slide switch or the like for moving to the "open" or "block" position can be used. The mounting position of the switch 8 on the handle 7 depends on the annular portion 1 of the handle 7.
5 may be used. In this case, it is desirable to provide a recessed portion (not shown) in the annular portion 15 of the steering wheel 7 and to embed the switch 8 therein so as not to hinder normal steering operation when driving the automobile. In the first embodiment, the switch 8 and the solenoid valve 5 are further provided.
A predetermined time is measured by the timer 17 after the switch 8 is pressed and the shut-off signal is transmitted to the solenoid valve 5, and the timer 17 is measured after the predetermined time has elapsed.
An open signal may be sent to the solenoid valve 5 from the controller. In this manner, even if the air damper 2 is turned off by pressing the switch 8 and the user forgets to open the air damper 2 again, it is possible to prevent the vehicle cabin from being shut off from the outside air.

ものである。FIG. 3 is a block diagram showing the configuration of the second embodiment of the present invention. According to a second embodiment of the present invention,
A gas concentration sensor 21 attached to a place not in contact with the outside air of the vehicle body (not shown) and a vent for taking the outside air into the vehicle compartment are provided to prevent the outside air passing through the vent from being taken into the vehicle compartment or blocked. A shutter 25 for switching, a shutter drive unit 24 for driving the shutter 25, a gas concentration threshold value storage unit 26 for storing a harmful gas concentration value in the outside air that is desired to be prevented from entering the vehicle interior, A gas concentration input unit 27 for setting a gas concentration value to be stored in the gas concentration threshold storage unit 26; an output value 28 of the gas concentration sensor 21; Output value 2
9 or a control unit 22 that compares the output value 32 of the open threshold value and sends the cutoff signal 30 to the shutter drive unit 24 or the open signal 31 to the shutter drive unit 24 via the timer 23. In the second embodiment, the shutter 25 serves as an outside air shutoff device, the shutter drive unit 24 serves as a drive device, the gas concentration value input unit 27 serves as a detection concentration setting device, and the cutoff threshold is set to a first predetermined concentration. In addition, the open threshold value corresponds to each of the second predetermined densities, but the present invention is not limited to each, and various forms can be considered.

る。The second embodiment of the present invention is configured as described above. A gas concentration value input unit 27 sets a gas concentration threshold value storage unit 26 with a cut-off threshold, which is a gas concentration value at which the shutter 25 is to be changed from an open state to a cut-off state.
An open threshold value for bringing the shutter 25 from the cutoff state to the open state is a value smaller than the cutoff threshold value by a predetermined value,
What is necessary is just to set it in connection with a cutoff threshold value.
Further, the open threshold value may be stored in the gas concentration threshold value storage unit 26 as a preset fixed value. The concentration of a harmful gas, such as nitrogen oxide, contained in the outside air detected by the gas concentration sensor 21 is sent to the control unit 22 as an output value 28. Here, examples of the harmful gas include hydrogen sulfide and carbon monoxide. The output value 28 is compared with the output value 29 of the shut-off threshold value stored in the gas concentration threshold value storage unit 26 when the shutter 25 is in the open state. In this case, a cutoff signal 30 is sent to the shutter drive unit 24.

If the value is smaller, the release signal 31 is sent to the shutter driver 24 via the timer 23. The timer 23 delays the release signal 31 sent from the control unit 22 for a predetermined time, for example, a time necessary for the harmful gas which may be slightly remaining in the vent after the release signal 31 is output to be dissipated. To the shutter drive unit 24. The shutter driving unit 24 outputs the shut-off signal 3 from the control unit 22.
When 0 is sent, the shutter 25 is turned off, and when the opening signal 31 is sent from the control unit 22 via the timer 23, the shutter 25 is turned on. Further, the shutter drive unit 24 sends the shutter 25 to the control unit 22.
The shutter state signal 33 for transmitting the "blocking" and "opening" states is transmitted.

Is blocked by the shutter 25 and discharged from the vehicle compartment (not shown) through the discharge port 37. By discharging the gas to the outside of the vehicle compartment, the harmful gas is easily dissipated from the ventilation port 34. The gas concentration sensor 21 is provided upstream of the shutter 25 in the outside air flow path of the ventilation port 34. In this way, the concentration of harmful gas can be detected by directly measuring the outside air taken into the vehicle cabin. The response time from when the gas concentration sensor 21 detects the harmful gas to when the shutter 25 is shut off is determined by the outside air
If it is kept shorter than the time that flows from the shutter to the shutter 25, it is possible to prevent almost no harmful gas from entering the car interior. Even if the response time cannot be kept small, it is possible to reduce the amount of harmful gas entering the car interior as much as possible. FIG. 5 is a cross-sectional view illustrating a configuration example of the ventilation port 34 when the shutter 25 is in an open state. The outside air indicated by the arrow 36 is taken into the vehicle interior (not shown) without being blocked by the shutter 25.
