Since a disc-shaped rotor is housed in the rotor and has a through hole at or near the center, the liquid that flows into the lower surface of the rotor from the through hole due to rotation of the rotor is moved outward due to centrifugal force. A lift force is generated on the rotor, and the rotor is balanced by the suction force from the stator and rotates smoothly without contacting the bottom wall, so that the stirring blades can efficiently stir the liquid in the container. It is simple and easy to handle and can be downsized, and the inside of the container is extremely easy to clean, making it possible to provide the device at a low cost.
