Abstract: A glass gob shaping apparatus for shaping glass into glass gobs with a plurality of shaping molds while causing glass to stably float, in which molten glass is supplied to shaping molds and shaped into glass gobs while causing glass to float by ejecting gas from the shaping molds and applying gas pressure, the apparatus including (1) an apparatus having a plurality of shaping molds, a gas supply mechanism for supplying said gas and a gas flow passage for supplying gas from the gas supply mechanism to the shaping molds, said gas flow passage having a buffer mechanism for suppressing the variance of gas ejection amounts in shaping molds during shaping of the glass which variance is caused by a pressure variance in gas ejection ports of other shaping molds and (2) an apparatus having a plurality of shaping molds and gas supply mechanisms for supplying said gas, said gas supply mechanisms being independently provided in a manner that one single gas supply mechanism corresponds to one shaping mold.
