To fill a casting mold with molten metal immediately without leaving no corners unfilled while hardly causing a pinhole by holding a molten metal pouring port of a crucible so as to be directed upward with the aid of an angle varying mechanism in starting the rotation of a rotary support and, thereafter, directing the molten metal pouring port to a molten metal receiving port of a casting mold with the aid of the angle varying mechanism.

When a driving cylinder is driven to lower a slant drive shaft 12, a crucible 6 is turned so that a molten metal pouring port 8 thereof is directed upward, and, under this condition, a rotary support 2 is rotated by a cylindrical rotary shaft 11. Thereby, the crucible 6 and and a casting mold 7, which are supported by the rotary support 2, are rotated around the axial line of the cylindrical rotary shaft 11 within a vacuum chamber 10. Then, a piston rod of the driving cylinder is extended to elevate the slant drive shaft 12, thereby elevating a connecting plate 19a and a coupling link 19. According to the elevation of the coupling link 19, a crucible holding body 3 is turned counter-clockwise with the aid of a pin 18, whereby molten metal in the crucible 6 is immediately discharged through the molten metal pouring port 8 by a large centrifugal force and is forcibly ejected to a molding part 30 through a molten metal receiving port 9 of the casting mold 7.
