[Action]

According to the environment testing device of the present invention, the slit for linear object insertion provided in the packing and extending inward and outward of the device does not elastically restore the packing itself when a linear object such as a cable or a pipe is not inserted in the slit. It is airtightly closed by force, and when the door is closed, the packing keeps the inside of the main body airtight.

When it is necessary to connect the sample placed in the device body and the power source outside the body with a linear object such as a cable or a pipe, the sample etc. is not removed from the linear object and these The linear object is placed at a predetermined position, and the linear object is placed in the linear object accommodation groove and inserted into the slit of the packing. The slit of the packing encloses the periphery of the linear object inserted therein airtightly by the pressing force of the packing itself applied from both sides of the slit, and thus when the door is closed, the inside of the apparatus is kept airtight by the packing.

When the sample is taken out from the inside of the apparatus main body, the linear object is simply removed from the slit of the packing and also removed from the linear object storage groove.
The measuring instruments are still connected.

Further, according to the environment testing device of the present invention, the linear object storage groove is inclined so as to become lower from the outside to the inside of the device, and the linear object insertion slit of the packing is on the extension line of the storage groove. Since the linear object is provided in the vicinity and is arranged in the storage groove so as to be lowered toward the inside of the apparatus, the linear object is incidental to the sample being exposed to the low temperature atmosphere in the environmental test apparatus. Even if dew condensation occurs on the device, the water droplets travel down the linear object toward the inside of the apparatus. Therefore, by providing the apparatus with water drop receiving means in advance, the water droplets travel along the linear object. It is possible to prevent inconveniences such as dripping outside to stain the surroundings of the device and damaging connected products such as a power supply and a measuring instrument installed outside the device.
