A movable bearing of a stirring shaft is provided to prevent an accident from a user by inhibiting damage to a stirring shaft when the stirring shaft is expanded or contracted by heat generated during stirring. A movable bearing of a stirring shaft includes a moving pipe(100), a guide pipe(200), a case, and a guide unit(400). The moving pipe is coupled to an end of the stirring shaft, has a predetermined length, and moves in and out of the guide pipe. The guide pipe is circular in shape and is installed in the case. The case consists of upper and lower cases(310,320) and fixes the moving pipe and the guide pipe for preventing separation of the moving pipe when the stirring shaft is expanded by heat. The guide unit is installed inside the guide pipe and includes a coupling part(430). The coupling part is coupled to an inner circumference of the guide pipe and includes guide grooves(410) and guide bodies(420). The guide bodies are circular in shape and are inserted in the guide grooves. |
