Abstract

PURPOSE:To aim at improvements in exhaust efficiency, by installlng two exhaust holes, which are connected to a duct at an interval in vertical directions, in a body outer panel as well as installing a vent hole in the duct at the intermediate height of these exhaust holes. CONSTITUTION:Inside air A enters an empty space S1 formed with a rear fender 14 and a trim material 15 from an air intake installed in a rear parcel shelf. Then, it enters the inside of a drafter duct 13 from a vent hole 13e and is divided into both upper and lower exhaust holes 14a and 14b whereby it is smoothly exhausted outside a car body 20. Water being penetrated from an upper exhaust hole 14a drops down to the inside of the drafter duct 13 and discharged outside a car from a lower exhaust hole 14b. With this constitution, exhaust efficiency is improvable.

In order to deal with this problem, a drafter duct 9 is provided inside the vehicle body outer panel 6 as shown in FIG. 3 to communicate with the tel air hole 3, and as shown in FIG. Near the exhaust hole 3 of this drafter duct 9,
A ventilation system equipped with a one-way valve 1o has been proposed to prevent trees from entering the vehicle body 8 from outside. That is, this one-way valve lo has a rubber sheet 12 that closes an opening 11a formed in a frame 11.
This rubber sheet 12 is fixed at its −L end with a screw 13 on the external force side 8a of the vehicle body 8 of the frame 11, and is formed so as to open only toward the outer side 8a of the vehicle body 8 of the frame 11. It is configured to allow air to pass through M from the inner side 8b of the car body 8, but to prevent wood from entering from the outer side 8a of the car body 8. However, in the drafter duct 3 used in such a ventilation system, a one-way valve 1o must be installed to prevent water from entering the air from outside, which increases manufacturing costs. .In addition, in order to release the internal air to the outside of Φ body 8, ko J, sheet 1
The air supply path is not formed unless the opening is pushed open by the pressing force generated by the flow of internal air, resulting in large ventilation resistance and low exhaust efficiency.

(Effects of the Invention) As described above, the present invention provides at least two exhaust holes at a predetermined interval in the vertical direction of the outer panel of the vehicle body, and communicates the exhaust holes with a duct to direct internal air to the at least two exhaust holes. Since the air is discharged from the inside of the vehicle to the outside of the vehicle, the effect of increasing the air efficiency is achieved. In addition, since the ventilation hole is provided at a mid-height position between at least two exhaust holes opened in the vertical direction, water entering from the exhaust hole passes through the ventilation hole and is formed between the outer panel of the vehicle body and the inner panel of the vehicle body. There is no fear that the liquid will enter the void, and a one-way valve is no longer required, reducing manufacturing costs.
