An air flow device for a closed motor vehicle or boat for positioning in the rear aperture thereof which includes structure for attaching the air flow device to the rear aperture. There is a plate which is transparent in at least the central region thereof. The attachment structure, which includes a pivot means, is pivotally attached to the bottom portion of the plate and to the lower rim of the aperture. There are two vertical side members, each of which is attached to an end of the plate so as to extend outwardly from the plate. Each of the vertical side members is in sliding relationship with one of the vertical sides of the rear aperture and/or of window glass mounted therein. There are two narrow end members, each of which is attached to an unoccupied end of one of the vertical side members and extends away from the plate. When the plate is in an upright position so as to close the rear aperture, the vertical side members extend outwardly from the rear aperture of the vehicle. When the plate is in an inwardly pivoted position so as to extend upwardly and inwardly from the rear aperture, thereby forming a gap between the top of the plate and the vertical plane of the rear aperture, the vertical side members extend inwardly from the rear aperture thereby preventing lateral air flow into the vehicle. The end members prevent the inwards pivoting of the device beyond the outer edges of the side members.
