のが公知である。(Conventional technology) Conventionally, as a monitoring device with an oil level gauge and an oil temperature gauge,
As illustrated in Utility Model Publication No. 58-7612, in order to make the scale of the thermometer easier to see through the viewing window,
The oil level gauge is inserted into a circular hole drilled at an eccentric position in the upper and lower retaining plates, and the oil level gauge is inserted into a small hole drilled in the center of both retaining plates so that it can freely move up and down, and the oil level gauge is inserted into the lower end of the support rod. It is known that a cylindrical float made of a thin metal plate is fixed and a marker is provided at the upper end that can be moved up and down using a thermometer as a guide rod.

間どりコスト高になる難点もあつた。(Problem to be solved by the invention) In the conventional monitoring device described above, if the support rod of the oil level gauge is bent even slightly from the vertical line, the float will come into contact with the inner wall surface of the body, or the soldered part of the float will be damaged. It used to get stuck on the inner wall surface, making it difficult to move up and down freely, and therefore the sign did not indicate the oil level scale correctly. In addition, conventional floats were formed from thin metal plates in the shape of a hollow cylinder, but they also had the disadvantage that it was very time-consuming and costly to solder the upper part to the body and the lower end of the support rod. .
