A low-pressure casting apparatus includes a lower mold disposed on a holding furnace, an upper mold configured to be raised and lowered relative to the lower mold, and a plurality of side molds disposed above the lower mold. A cavity is formed between the lower mold, the upper mold and the side molds. The lower mold includes a lower cast main part forming an inner bottom surface of the cavity, and a lower mold base part holding the lower cast main part. The lower cast main part has a sprue bushing that opens into the cavity. At least one of the side molds is advanceable and retractable relative to a mold center. The lower mold base part has guide pillars that restrict advanced positions of the side molds. The horizontal adjustment gap is provided between the lower cast main part and the lower mold base part.
