[Embodiment] An automobile 1 has a hood portion 2 in which a motor is housed.
And a passenger compartment 5 having front seats 3 and rear seats 4, a trunk compartment 6 for storing luggage and the like, and the prime movers mounted on the left and right sides of the bonnet section 2 and the left and right sides of the trunk compartment 6. It consists of driven wheels 7. A display unit for displaying the vehicle speed, the number of revolutions of the prime mover and the like, a blower unit for blowing ventilation air, warm air and the like into the vehicle, and a handle unit 8 for controlling the traveling direction of the automobile 1 in the front portion of the vehicle compartment 5. And a start switch for starting the prime mover.

At the center between the front seats 3 is formed a hand shake lever 10 which is manually operated. The left and right front doors 11 and the left and right rear doors 12 are formed on both sides of the vehicle compartment 5 so as to be openable and closable. The upper half of the front door 11 and the rear door 12 are molded with translucent window glasses 13 and 14 which can be opened and closed vertically. The front and rear upper half sides of the vehicle compartment 5 are translucent front glass 15 and rear glass.
It is blocked at 16.

A horizontal base portion 17 blocks up to the lower portion of the rear glass 16 behind the upper portion of the rear seat 4 of the vehicle compartment 5. The horizontal base 17 separates the interior space of the vehicle compartment 5 from the interior space of the trunk compartment 6. A ventilation passage is formed in the rear side wall of the vehicle compartment 5 to communicate the inside of the vehicle compartment 5 with the vehicle side and the inside of the trunk compartment 6 with the outside of the vehicle.

Exhaust ports 18 facing the outside of the vehicle are formed on the left and right sides of the vehicle body and in the lower portion of the trunk chamber 6. The ventilation passage has a ventilation resistance that increases toward the vehicle interior and decreases toward the vehicle exterior.

A ventilation device 20 for discharging the air in the vehicle compartment 5 into the trunk compartment 6 is mounted on the horizontal base 17. The ventilation device 20 is driven by a solar cell 21 as a power source, and is formed on the same substrate body 22 as the ventilation device 20.

When the air blower of the automobile 1 is operated, the air pressure in the passenger compartment 5 rises if outdoor air is used.
It is discharged from the exhaust port 18 at that pressure. Further, when the air blower is stopped and the natural ventilation opening at the front is opened, air flows into the vehicle compartment 5 due to the wind pressure during traveling, and is discharged from the exhaust opening 18. In this case, when the automobile 1 is stopped, exhaust is not performed.

The substrate 22 has a pair of U-shaped rail portions 24 each having a groove 23 formed in the opposing surface portion, a portion 25 connecting the outside of the bent portion of the rail portion 24, and the rail. -End plates 26 that form bent portions of the rail portion 24 on both sides, a base portion 27 that tilts and supports the rail portion 24, and the horizontal base portion 17 that is stretched on both front and rear sides of the base portion 27. And a mounting piece 28. A solar cell 21 mounted on a mounting support plate 29 is erected and fixed between the rail portions 24.

A pair of ventilation devices 20 are attached to the ends of the rail portion 24. Since the ventilation device 20 is driven by the solar cell 21, a DC motor is used to further simplify the circuit configuration. A shutter plate 30 is slidably mounted in the groove 23 of the rail portion 24.

A rotary shaft 32 driven by an electric motor 31 is pivotally supported on the end plate 26, and a shutter moving gear 33 is mounted on the rotary shaft 32. The shutter moving gear 33 is the shutter plate.
The shutter plate 30 is opened and closed by engaging the engaging holes formed on both sides of the shutter plate 30 and rotating the shutter moving gear 33.
An electric motor 31 for driving the shutter moving gear 33 is operated by using a storage battery 19 mounted on the automobile 1 as a power source, and a control circuit
Forward / reverse rotation is controlled by 34.

When the shutter plate 30 closes the solar cell 21 and the ventilation device 20, the ventilation device 20 stops its operation, and when it is opened, the solar cell 21 is irradiated with sunlight and the ventilation device 20 is closed. Be driven. By operating the ventilation device 20, the air in the vehicle compartment 5 is discharged into the trunk 6 and is discharged from the exhaust port 18 to the outside of the vehicle. Further, as the air in the vehicle compartment is exhausted to the trunk compartment, the air outside the vehicle is sucked in from the natural ventilation port in the front part of the vehicle compartment 5 to ventilate the vehicle compartment 5. Since the ventilation device 20 is driven by the solar battery 21, the storage battery can be operated by a long-term operation even during parking.
The charge capacity of 19 does not decrease.

Therefore, it is possible to suppress an increase in the vehicle compartment temperature due to outdoor parking in the summer. In the embodiment, the shutter plate is used to supply electric power from the solar cell 21 to the ventilation device 20.
