PROBLEM TO BE SOLVED: To provide a magnet coupling capable of suppressing demagnetization while reducing thrust load.SOLUTION: In a magnet coupling, a driving side rotor 23 driven by a motor and a driven side rotor 24 rotating with rotation of the driving side rotor 23 are arranged vertically oppositely so as to hold a partition wall 12b therebetween; and permanent magnets are arranged on each opposite surface of the driving side rotor and driven side rotor. On the opposite surfaces of the driving side rotor and the driven side rotor, permanent magnets 25 and magnetically permeable yokes 26 are alternatively arranged at equal intervals with respect to a rotational direction, the number of permanent magnets being identical to the number of magnetically permeable yokes. The permanent magnets of the rotors are arranged so as to make the same polarities face each other.SELECTED DRAWING: Figure 3 |
