<P>PROBLEM TO BE SOLVED: To provide an environmental test device capable of suppressing dew condensation inside and outside of a test tank which is put into a low-temperature state. <P>SOLUTION: An environmental test device 1 comprises a test tank 2, a work support mechanism 3, a cooling mechanism 4 and a dry gas supply mechanism 6. The work support mechanism 3 is provided with a work mounting table 15 and a mounting table support shaft 16 which penetrates a wall of the test tank 2 from the outside of the test tank 2, extends into the inside, and supports the work mounting table 15. The mounting table support shaft 16 is a hollow shaft, and the dry gas supply mechanism 6 supplies dry gas from the outside of the test tank 2 to the inside of the test device 5 through the hollow part 64 of the mounting table support shaft 16. Drop of the temperature of the out-of-tank portion 16a of the mounting table support shaft 16 is suppressed by heat exchange between the mounting table support shaft 16 and the dry gas, and therefore dew condensation can be suppressed. In addition, the supply of dry gas suppresses dew condensation inside the test tank 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
