PCT No. PCT/JP92/01387 Sec. 371 Date Jun. 24, 1993 Sec. 102(e) Date Jun. 24, 1993 PCT Filed Oct. 26, 1992 PCT Pub. No. WO/9307977 PCT Pub. Date Apr. 29, 1993.In a method of vacuum casting molten metal sucked from a molten metal reservoir into a cavity held under a reduced pressure by opening a gate having been blocking the communication between the molten metal reservoir and the cavity, the trapping of gas and foreign matter in the cavity is effectively prevented. To this end, an accommodation space for accommodating gas and foreign matter is provided in the molten metal reservoir. The accommodation space is provided at a position from which the accommodated matter is not sucked into the cavity.
