STIRRER AND METHOD FOR MANUFACTURING GLASS PLATE

The present invention provides a stirrer 12 which includes a shaft 13 and a plurality of stirring blades 14 attached along the longitudinal direction of the shaft 13, and which is used for stirring molten glass in a stirring tank 6 by causing the plurality of stirring blades 14 to turn about the shaft 13 with the movement of the shaft 13. Each stirring blade 14 (blade body 14a) has a through holeopening 14aa, and a distal end 14ab of the stirring blade 14 (blade body 14a) extends along the longitudinal direction of the shaft 13. The plurality of stirring blades 14 are attached such that whenthe stirring blades 14 turn about the shaft 13, the closer a stirring blade 14 is to the upper end of the shaft 13, the more that stirring blade 14 is delayed in phase about the shaft 13 than the stirring blades 14 on the lower end of the shaft 13. 一种搅拌器(12)，其具备：轴(13)；以及多个搅拌叶片(14)，其沿着轴(13)的长度方向而被安装于轴(13)，该搅拌器用于使多个搅拌叶片(14)随着轴(13)的旋转而绕轴(13)回转来对搅拌槽(6)内的熔融玻璃进行搅拌，搅拌器(12)构成为：搅拌叶片(14)(叶片体(14a))具有贯通开口部(14aa)，搅拌叶片(14)(叶片体(14a))的前端部
