る。(Effect of the invention) As described above, according to the invention, an air pocket is formed in the upper part of the cylinder, so even if the liquid level rises, the liquid level within the cylinder remains at a predetermined height due to the air in the air pocket. Therefore, the display plate and the transparent plate can be isolated from the liquid without the need for a conventional sealing structure inside the cylinder, and the manufacturing cost of the liquid level gauge can be reduced. In addition, in the present invention, the lower surface of the cylinder is set below the pivot point of the pointer, so the pointer is located far above the bottom surface of the cylinder, and therefore, when the fuel level rises, the pointer's position is lower than the pivot point of the pointer. It is possible to effectively prevent the tip side from coming into contact with the liquid surface of the fuel.
