連結装置。 A first connecting member and a second connecting member made of a magnetic material are opposed to each other with a gap therebetween, and a magnetic field is formed in the gap to magnetize the magnetic particles present in the gap. In a magnetic particle type electromagnetic coupling device that couples a coupling member and a second coupling member by the magnetic particles, the coupling surfaces of the first coupling member and the second coupling member are connected to the surface of the magnetic particles. A magnetic particle type electromagnetic coupling device characterized in that a coating having a Vickers hardness of HV2000 or more is provided on at least the surface of the magnetic particles by a vapor deposition method.
