PROBLEM TO BE SOLVED: To provide a cartridge tank allowing confirmation of an oil amount in a comfortable standing position without bending down by providing a mirror body turning and mirroring an oil gauge during fueling. SOLUTION: In a state of arranging a refueling opening 11 in a lower part when housing the cartridge tank 3 in an oil heater body 1, the mirror body 15 slightly descends by gravity with respect to a support 10, one corner part of a spindle 7 fits in a first groove part 19A, and by this, the mirror body 15 vertically closes so as to cover a whole of the oil gauge 6. When the cartridge tank 3 is reversed upside down during fueling, the mirror body 15 slightly descends by gravity, the corner part of the spindle 17 disengages from the first groove part 19A and moves into a second groove part 19B to allow turning of the mirror body 15, and one part 15A of the mirror body 15 abuts on a tank body side and stops at a position substantially 45 degrees from perpendicularity.
