As shown in Japanese Patent No. -18852, in running in an open state with a hood removed, the main flow of air on the upper side of the vehicle body is separated from the front header and then rolled into the cabin from the rear side of the seat headrest. In some cases, a wrap-around airflow suppression plate is provided at the rear of the sheet, paying attention to the coming. As a result, the entry of the entrained airflow into the cabin is suppressed by the entrained airflow restraint plate, and the hair of the occupant is prevented from being disturbed.

[0003]

However, in the above case,
Not only cannot the main air entrainment itself be suppressed,
As a result of the main flow of air being suppressed by the airflow suppression plate positioned near the headrest, a wake that generates a vortex is formed behind the airflow suppression plate, and the vertical width of the flow region after that is large. I have to be. For this reason, a large pressure difference is generated between the front side of the front window glass and the rear side of the front window glass, and the pressure resistance is increased.

In order to achieve the above object, according to the present invention (the invention according to claim 1), there is provided a closed state in which an upper part of a vehicle body is covered by a hood, In an open car body structure capable of selectively taking an open state in which a state of covering an upper part is released and an upper part of the vehicle body is opened, an air flow suppressing means is provided behind a seat in a cabin of the vehicle body. In the open running state, the air flow suppressing means is an air outlet for blowing gas upward, and winds the air flow separated at the front of the cabin into the cabin. It is configured to regulate and guide the vehicle rearward. With the above configuration, even when the main flow of the airflow separated at the front of the cabin is going to be caught in the cabin during the open running, the air outlet as the airflow suppression means is moved upward from the air outlet. The gas blown toward the air restricts the air flow from being caught in the cabin and guides the air flow to the rear of the vehicle body, so that the air flow moves to the rear of the vehicle body without forming a vortex, A wake having a narrow vertical width is formed on the rear side of the vehicle body, so that a pressure difference between the front and rear of the cabin front can be suppressed. For this reason, the pressure resistance can be reduced as much as possible during traveling in the open state.
