Claims

[Claims for Utility Model Registration] A cylindrical driving member attached to a flywheel of an engine, and a driven member provided inside the driving member so as to be rotatable concentrically and relative to the driving member, The rotational force of the engine is transmitted to the driven member by magnetically coupling magnetic particles housed in the gap between the inner peripheral friction surface of the driving member and the outer peripheral friction surface of the driven member. In a magnetic particle type electromagnetic clutch for a vehicle, the drive member is supported by the flywheel so as to be relatively rotatable, and a torque is provided between the flywheel and the drive member that can be elastically deformed according to the relative rotation between the two. A magnetic particle type electromagnetic clutch for a vehicle characterized by having a transmission member interposed therebetween.
