<P>PROBLEM TO BE SOLVED: To provide a magnetic coupling device which sufficiently suppresses the occurrence of eddy current in a partition wall part and thereby suppressing the energy loss caused when driving force is transmitted while improving the strength of the partition wall part. <P>SOLUTION: A magnetic coupling device 100 includes: a load side rotating body 10 including magnet parts 12; a driving source side rotating body 20 including magnet parts 22 magnetically coupling to the magnet parts 12; and a partition wall part disposed at a position which is located between the load side rotating body 10 and the driving source side rotating body 20 and faces the magnet parts 12, for separating the load side rotating body 10 from the driving source side rotating body 20. The partition wall part includes a wall part 34 made of a nonmagnetic resin material, and twelve reinforcement plates 33 arranged at intervals twice as wide as those of magnet poles of magnet part 12 in a rotation direction B, and made of a nonmagnetic metal material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
