い。Reference numeral 2 denotes a transparent window, which is provided in the test tank section 3. Here, the test tank upper lid part 3 is formed into a roof shape so as to form a chevron-shaped inclined surface. A test tank tilted like this
The reason why the viewing window 2 is provided in the second lid part 3 is to enable observation and photography to be performed facing the inclined surfaces of a plurality of test pieces arranged at predetermined intervals. The see-through window 2 is made of a transparent material such as glass or transparent plastic. The size (area), thickness, etc. of the transparent window 2 are appropriately designed in consideration of the size of the apparatus and test piece, heat retention, etc. Also,
The see-through window 2 may be a -4 ton window to improve heat retention.

構成としである。The wiper 6 is provided inside the test chamber l, and is connected to the transparent window 2.
It moves back and forth while making contact with the inner surface of the transparent window to remove water droplets from the inner surface of the viewing window. The wiper 6 includes a wiper rubber 6a and a magnet 6b embedded inside the wiper rubber 6a. On the other hand, on the outer surface of the see-through window 2, a moving member 7 is provided which is moved by a motor 9 via a transmission means 9a such as a ball screw or a timing belt (plane 21 is a ball screw). This moving member 7 is
- It is provided opposite to the wiper 6, and similarly to the wiper 6, it has a structure including a rubber member 7a and a magnet embedded inside the rubber member 7a.
