description Provided is a measuring area for a wind-tunnel testing apparatus, which can measure a more practical air force while suppressing the influences of indraft air flows from the boundary layer of a floor face and the side portions. A measuring chamber (7) of a wind-tunnel testing apparatus (1) includes a placing area (17) for placing an automobile (41) along a floor face (15) in a wind-tunnel (3), and performs tests by applying an air flow blown in the wind-tunnel (3), to the automobile (41) placed in the placing area (17). The measuring chamber (7) is equipped, on the floor face (15) positioned upstream of the placing area (17) in the air flow direction, with a slit (19) arranged to extend in an intersecting direction to intersect the air flow direction, for sucking the portion of the air flow near the floor face, and side suction areas (23) arranged in the two side portions of the placing area (17), for sucking indraft air flows (R) to come into the placing area (17) from the side portions.
