ABSTRACT:
A magnetic particle type electromagnetic coupling apparatus comprises a first coupling body having a coupling surface at its inner circumferential part, a second coupling body constituted by two members divided in the axial direction which is placed inside the coupling surface of the first coupling body and has a coupling surface connectable to the coupling surface of the first coupling body, magnetic particles filled between the coupling surfaces, an electromagnetic coil received in the second coupling body to magnetize the magnetic particles thereby controlling connection between the coupling surfaces, a rotary body placed at the inner circumferential part of the second coupling body so as to transmit torque and a damper means which is placed between the second coupling body and the rotary body so as to transmit torque and which is sealingly held between the two members of the second coupling body.
