Claims

[Scope of utility model registration request]

It consists of a hub formed in the shape of a flat cylinder with a bottom, an armature plate formed in the shape of a cylinder concentric with the hub, and a disc-shaped armature fixed to the armature plate. In an electromagnetic clutch equipped with an armature assembly in which vulcanized rubber is bonded and inserted into an annular space between an outer peripheral surface and an inner peripheral surface of an armature plate, at least one end surface of the vulcanized rubber is It is characterized by being formed into a truncated conical shape with a gently sloping ridgeline that gradually moves away from the opposing surface as it goes from the periphery to the outer periphery, with the inner periphery end being chamfered in a convex shape and the outer periphery end being chamfered in a concave shape. An electromagnetic clutch.
