Claims

[Claims for Utility Model Registration] (1) A first connecting body having a connecting surface on the inner periphery, and a connecting surface disposed on the inner periphery of the first connecting body and connectable with the connecting surface. a second connecting main body formed on the outer periphery and consisting of two members divided into two in the axial direction; and magnetic particles filled between each of the connecting surfaces;
An electromagnetic coil that magnetizes the magnetic particles to control the connection state of each connection surface, and an electromagnetic coil that opposes the two members with an axial gap between them at the inner circumference of the second connection main body. and a rotary hub connected to a rotating shaft, which is provided so as to be able to engage with the rotary hub and the second connecting body to transmit torque, and is housed so as to be hermetically sealed between the two members of the second connecting body. In the magnetic particle type electromagnetic coupling device comprising a damper having a coil spring, a window portion for holding the coil spring is provided on each surface of the two members of the second coupling main body facing opposite to both surfaces of the rotating hub. A magnetic particle type electromagnetic coupling device characterized in that each plate is provided with a plate made of a highly hard material. (2) The magnetic particle type electromagnetic coupling device according to claim 1, wherein the plate made of a highly hard material is a steel plate.
