Abstract
In an electromagnetic clutch, the movable clutch plate which acts as an armature is connected to a drive member by a spring plate having a plurality of deformable arms. The deformable arms are rigidly connected to the drive member at one end thereof while the opposite ends of the arms are connected to the clutch plate by rivets with the reduced armature shank portions of the rivets being located in elongated holes in the ends of the arms. The heads of the rivets are located in notches in the drive member to prevent relative rotation of the clutch plate relative to the drive member while permitting axial movement relative thereto.
