To improve durability by installing a part or the whole of a molten metal sucking tank, an intermediate tank and a transfer tank at the outside of a furnace.

This apparatus for sucking the molten metal 7 and transferring it to a using position is composed of the molten metal sucking tank 6 for sucking the molten metal 1 from a holding furnace 10, the intermediate tank 12 for temporarily storing the molten metal 7 and a transfer tank 22 for transferring the molten metal sucked from the intermediate tank 12 by fixed quantity. And the molten metal sucking tank 1, the intermediate tank 12 and the transfer tank 22 are mutually connected with a transfer tube, and a sucking tube communicated with the holding furnace 10 for molten metal 7 is connected to the sucking tank 6. In the transfer tank 22, a transfer tube for transferring the molten metal to the using position is provided, and heaters and inactive gas supplying/discharging tubes 9, 20, 35 are provided in respective the tanks 6, 12, 22.
