Claims

[Claims for Utility Model Registration] A driving member that has a cylindrical shape with a bottom and is rotated around a center line, and a driving member that is provided inside the driving member with a predetermined gap therebetween so as to be concentric with the driving member and rotatable relative to the driving member. A labyrinth is formed between the driven member, which is provided on the driving member with the gap in the axial direction sandwiched between the driven member and which allows ventilation in the axial direction at the inner peripheral portion, and the driven member. a pair of annular labyrinth members forming a substantially sealed annular magnetic particle storage space together with the driving member and the driven member, and the magnetic particles are filled into the gap by magnetic force, whereby the driving member In a magnetic particle type electromagnetic clutch of the type in which rotation is transmitted to the driven member, an inner circumferential portion is connected to the outside through the inner circumferential portion of the driven member between the bottom surface of the driving member and the labyrinth member facing thereto. A communicating flat annular space is formed, and the labyrinth member and/or the drive member is provided with a plurality of fins extending radially from the inner peripheral part to the outer peripheral part within the flat annular space, and further, the outer peripheral part of the flat annular space is An exhaust hole that communicates with the outside is formed in the driving member, so that as the driving member rotates, a cooling air flow reaches the exhaust hole through the inner circumference of the driven member and the flat annular space. A magnetic powder type electromagnetic clutch characterized in that the magnetic particle type electromagnetic clutch is formed in
