In other words, a high-temperature environment test for testing the vaporization state of gasoline supplied to the engine and the performance of the air conditioner indoors generally includes a chassis dynamometer that rotates while supporting the drive wheels on rollers while the automobile is fixed. The test is performed in a test room, to which a wind tunnel for supplying an airflow corresponding to the traveling wind of the vehicle is connected. The temperature and humidity of the air flow are adjusted by an air conditioner provided at an intermediate portion of the wind tunnel, and a solar radiation device for reproducing the effect of solar radiation from the sun is provided on the ceiling of the test room.

照）。When a front wheel drive vehicle is tested by such a high temperature environment test apparatus, the front wheels, which are the drive wheels, are supported by rollers of a chassis dynamometer. Since the position shifts rearward, the distance between the wind tunnel nozzle and the front end of the vehicle body increases, which adversely affects the measurement accuracy. Therefore, when testing a front-wheel drive vehicle, an extension nozzle housed in the nozzle of the wind tunnel is drawn rearward to maintain a constant distance from the front end of the vehicle body (see Japanese Utility Model Laid-Open No. 55-44206). .

して試験データに誤差が発生する問題がある。By the way, if the extension nozzle is retractably accommodated in the nozzle of the wind tunnel as in the above-mentioned conventional high-temperature environment test apparatus, not only does the nozzle increase in size, but not only presses the volume of the test chamber, but also increases the size of the nozzle. Since the cross-sectional shape of the nozzle becomes discontinuous, the flow velocity distribution of the traveling wind is disturbed, and as a result, there is a problem that an error occurs in test data.

If the extension nozzle is stored under the floor when performing the test, it is possible to eliminate the influence of the extension nozzle on the air flow and perform a precise test. In this case, the entire lower surface of the vehicle can be heated by operating the movable road surface radiation device provided on the upper surface of the extension nozzle. In addition, since the underfloor is used as the storage space for the extension nozzle, not only does the pressure of the test chamber not be limited, but also the work of moving the extension nozzle can be performed easily. Furthermore, if the extension nozzle is raised when testing a front-wheel drive vehicle, it is possible not only to make the outlet sufficiently close to the front end of the vehicle to perform a precise test, but in that case it is unnecessary.
