To provide a magnetic levitation type rotation introduction apparatus which adopts a magnetic levitation type needless to use a magnetic fluid seal, and which makes it possible to make a length in an axial direction as a device short as much as possible.
There is provided a rotor 12 which outputs a rotation power, and the rotor 12 is rotation-supported at a prescribed position in a state of non-contact by two or more pairs of radial magnetic bearings 40 which are arranged in a radial direction of the rotor 12, and control a radial direction variation of the rotor 12 in a state of non-contact, and axial magnetic bearings 50 which are separated into 3 or more pairs and arranged in a circumference of the rotor 12, and control a axial direction variation of the rotor 12 in a state of non-contact. Radial electromagnets 44 of the radial magnetic bearing 40, and axial electromagnets 54 of the axial magnetic bearing 50 are arranged on approximately the same plane, and are fixed to a casing part 14.
