PURPOSE:To eliminate eccentricity, to realize stabilized high-speed rotation, and further to enhance durability of the title device by supporting a main agitating shaft on the main vessel body irrespective of the attachment and detachment of a lid. CONSTITUTION:The lower bearing 5 for supporting the main agitating shaft 7 arranged at the center of the main vessel body 3 is provided on the bottom in the main vessel body 3. A driven magnetic body 6 induced by the driving magnetic body 51 arranged outside the bottom of the main vessel body 3 is fixed to the shaft 7, and one or >=2 impellers 31-33 are fixed to the shaft 7. An upper bearing 8 is mounted on the shaft 7 to support the shaft 7, and fixed in the main vessel body 3 by a bearing support 20. An end plate 40 capable of being opened and closed irrespective of the shaft 7 is provided to the main vessel body 3. As a result, eccentricity is eliminated, stabilized high-speed rotation can be realized, and the durability of the device is improved. |
