Abstract
An oil gauge for a cartridge-type oil tank capable of quantitatively indicating the amount of oil in the tank both during use of the tank and when oil is fed to the tank, while providing the tank with airtightness. The oil gauge includes a transparent cover plate arranged on a side wall of the tank so as to airtightly cover an opening in the side wall of the tank. A gauge base is mounted on an inside of the cover plate. On the gauge base are pivotally mounted an arm rod which is provided with a float and an oil indicator having a scale for quantitatively indicating the amount of oil in the tank. The scale is visible through the transparent cover plate. The oil gauge also includes a pair of stoppers arranged on opposite sides of the arm rod such that one stopper pivotally varies the position of the oil indicator with variations in oil level when the tank is in a working position and the other stopper pivotally varies the position of the oil indicator with variations in oil level when the tank is inverted and placed in an oil feed position.
