A molten metal supply device designed to mount a ladle-rotating motor on a support frame and dispose a ladle-rotating rotation transfer mechanism in a predetermined link of a ladle-carrying link mechanism so as to be able to perform precise position control (tilt angle control) of a ladle. The rotation transfer mechanism is driven by the ladle-rotating motor mounted on the support frame so as to rotate the ladle. The rotation transfer mechanism is provided in a link of the ladle-carrying link mechanism for carrying the ladle. The rotation transfer mechanism is constituted by two parallel linkages. Each parallel linkage has a pair of bar links whose opposite ends are attached to two rotors respectively. When the ladle-rotating motor is being stopped, the ladle can be kept in a predetermined posture by the parallel linkages even if the ladle-carrying link mechanism has any operating posture.
