<P>PROBLEM TO BE SOLVED: To provide a stirring device which can improve the lubrication performance and wear resistance of a bearing arranged in a stirring tank, and can be elongated in life. <P>SOLUTION: The stirring device 1 having a stirring blade 4 rotatably arranged in the stirring tank 2 which can house a liquid L to be stirred via the bearing 7 incluldes: a magnetic coupling mechanism 9 which has a drive-side rotor 91 arranged outside the stirring tank 2 and rotating on the basis of a drive force from a drive source, and a driven-side rotor 92 connected to the stirring blade 4 in the stirring tank 2, and connects the drive-side rotor 91 and the driven-side rotor 92 via a partitioning wall; and a rotating blade 8 which rotates together with the stirring blade 4. The stirring device generates negative pressure by using the rotating blade 8 and sucks the liquid L to be stirred to a region in which the bearing 7 slides by the negative pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
