PROBLEM TO BE SOLVED: To provide a molten glass stirring device capable of improving stirring effect for molten glass made of platinum-based material in a molten glass carrier pipe without increasing a load on a pipe wall of the molten glass carrier pipe.SOLUTION: A molten glass stirring device for stirring molten glass made of platinum-based material in a molten glass carrier pipe includes a first stirring part and a second stirring part. The first stirring part consists of: a rotatable central axis; and a plurality of first stirring wings arranged spaced from each other along the longitudinal axis direction of the central axis. The second stirring part consists of: a plurality of support members arranged around the central axis so as to have the same longitudinal axis direction and the same rotation center as the central axis and rotatable in the opposite direction to the central axis; and a plurality of second stirring wings arranged spaced from each other along the longitudinal axis direction of the plurality of support members. |
