said plurality of airflow members comprise (a) a plurality of airflow members (20, 21) having a large number of airflow holes (20a, 21a) and (b) a mesh plate (19) which are arranged in layers in an inner chamber following said ventilation opening (11a) of said body housing (11) through gap members (22), and said large number of airflow holes (20a) of one airflow member (20) and the large number of airflow holes (21a) of another airflow member (21) are arranged eccentrically in the whole surface of each said airflow members (20, 21) so that the large number of airflow holes (20a) of one airflow member (20) are not aligned with the airflow holes (21a) of another airflow member (21), and (c) a ventilation substrate (18) having an airflow function.

3. A car window ventilation system according to claim 1, further comprising a fan unit (30) additionally provided for reinforcing said ventilating function.

4. A car window ventilation system according to claim 3, wherein a solar panel (41) is attached to the car so that said solar panel (41) serves as a power supply for actuating said fan unit (30).

5. A car window ventilation system according to claim 3, wherein a lead wire is connected from said solar panel (41) to a battery (47) properly provided in the car so that electric power from said solar panel (41) attached to the car is supplied to said battery (47).

6. A car window ventilation system according to claim 4, wherein a temperature sensor (45) for setting temperature conditions for running/suspension of said car window ventilation system is provided in an electrically conducting system which performs electric conduction from said solar panel (41) attached to the car to said fan unit (30).

7. A car window ventilation system according to claim 1, wherein drain holes (26, 26′

) are provided so as to be opened from an inner chamber continued to said ventilation opening (11a) of said body housing (11) to an outer surface of said body housing (11).

8. A car window ventilation system according to claim 1, wherein said body housing (11) includes sunshade and weatherproof eaves (12) in a region of said ventilation opening (11a).

9. A car window ventilation system according to claim 1, wherein said ventilation system is applied to a window provided in a rear portion of the car.

10. A car window ventilation system according to claim 3, wherein, as a power supply for actuating said fan unit (30), a cigarette lighter power supply of the car is used and a power supply for a solar generator of a solar car is used when said ventilation system is installed in said solar car.

11. A car window ventilation system according to claim 1, wherein an alarm is incorporated in a circuit for performing electric bridge connection between said blocking plate A (13) and B (14 or 14′

) and said grooves (11b, 11c) of said body housing (11), whereby warning is issued for the purpose of preventing said ventilation system from being stolen or destroyed when said circuit is interrupted.

2. A car window ventilation system comprising a body housing (11), blocking plates A (13) and B (14′

), and a plurality of airflow members (18, 19, 20, 21, 55) wherein;

said body housing (11) includes grooves formed in circumferential edges thereof, and a ventilation opening (11a) formed in a center portion thereof, said grooves having, at least, a rear groove (11b) formed in a rear side of a car window region, a front groove (11c) formed in a front side of the car window region, and a lower groove (11d) formed in a lower side of the car window region, a right end of said blocking plate A (13) and a left end of said blocking plate B (14′
