PROBLEM TO BE SOLVED: To carry a molten metal in a state of being safely and certainly stored without providing a complicated moving mechanism in a molten-metal storing chamber, and to make maintenance easier. SOLUTION: The molten metal feeding device includes: a molten metal storing housing 100 having a molten metal storing chamber 110 for storing a molten metal and having a molten metal discharging part 120, at the front end of which a molten metal discharging port 121 for discharging a molten metal is formed; a molten metal introducing pipe 200, which is fitted to the molten metal storing housing 100 in such a manner that an upper end 210 of the pipe 200 is positioned inside the molten metal storing chamber 110 and which introduces the molten metal into the molten metal storing chamber 110; and a rotation mechanism 300 for giving the molten metal storing housing 100 rotational power to move the molten metal discharging port 121 upward or downward. When the upper limit of molten metal stored in the molten metal storing chamber 110 is set to be the position directly before the position where the molten metal stored in the molten metal storing chamber 110 starts to flow out of the molten metal discharging port 121 under the condition that the molten metal storing housing 100 stands upright, the molten metal introducing pipe 200 is fitted to the molten metal storing housing 100 so that the upper end 210 thereof is positioned slightly lower than the upper limit of stored molten metal.
