PROBLEM TO BE SOLVED: To certainly stir the content in a stirring tank by optimizing the size of the motor of a drive part corresponding to stirring load while keeping the stirrer small-sized. SOLUTION: The stirrer 1 is equipped with a stirring shaft part 2 having an outer magnet 51 and an inner magnet 41 for operating the shaft 4 interlockingly in a casing 3a in a non-contact state from the outside and inside of the casing, the stirring tank 3, which has stirring blades for stirring the content by the rotation of a shaft, provided in the casing in a hermetically closed state and a drive part 6 for transmitting rotatory power to the stirring shaft part. The drive part has the motor 7 arranged to one end part thereof and the drive magnet 81 arranged to the other end part thereof to interlock with the output shaft 27 of the motor and the stirring shaft part has a driven magnet 52 arranged to one end part thereof to interlock with the outer and inner magnets outside the casing, and the drive part and the stirring shaft part are uniaxially arranged so that both magnets are opposed to each other.
