MEASURING PART OF WIND TUNNEL TEST DEVICE AND WIND TUNNEL TEST DEVICE USING THIS

PROBLEM TO BE SOLVED: To provide a measuring part of a wind tunnel test device capable of measuring an air force closer to an actual air force by suppressing an influence of an airflow flowing in from a border layer of a floor surface and sides. SOLUTION: The measuring room 7 of a wind tunnel test device 1 has an arranging part 17 for arranging an automobile 41 along a floor surface 15 in a wind tunnel 3, and a test is performed by applying the airflow blown in the wind tunnel 3 to the automobile 41 arranged in the arranging part 17. This room comprises: a slit 19 formed at the floor surface 15 which is located at the upstream side in the airflow direction of the setting part 17 for sucking a part of the airflow in the vicinity of the floor surface; and side sucking parts 23 arranged at both sides of the arranging part 17 for sucking the airflow R flowing from the sides into the arranging part 17.
