Claims

[Claims for Utility Model Registration] A cylindrical driving member that is rotated around a center line, a cylindrical hub portion for connecting to a driven shaft in the center, and a cylindrical hub portion that is located inside the driving member and is concentric therewith. a driven member provided to be relatively rotatable; and an annular member attached to both ends of the driving member for accommodating magnetic particles together with the inner circumferential surface of the driving member and the outer circumferential surface of the driven member. an annular labyrinth member forming a space, and magnetically coupling the magnetic particles within the gap between the inner circumferential surface of the driving member and the outer circumferential surface of the driven member. In a magnetic particle type electromagnetic clutch of a type that transmits rotational force to the driven member, a first annular member having an inner peripheral edge close to an outer peripheral surface of one end of the hub portion is disposed on one inner peripheral portion of the labyrinth member. The first annular wall is located at a predetermined distance from the wall toward the other end of the hub portion in the direction of the center line, and is brought into close contact with the outer peripheral edge of the first annular wall at the outer peripheral edge. A second annular wall forming an inward annular groove between the annular wall and the first annular wall, and a discharge hole communicating with the annular groove is formed in the first annular wall. electromagnetic clutch.
