Claims

[Scope of Claim for Utility Model Registration] (1) An armature, a power transmission part such as an armature hub, and an armature interposed between the armature and the power transmission part and alternately connected to the armature and the power transmission part along the circumferential direction. In armature assemblies such as friction plate type electromagnetic clutches made of disc-shaped spring members, this Disc-shaped spring members each having a through hole bored at a position that matches each relief hole are overlapped, and the spring member is attached to the armature at an intermediate portion between the through holes at equally spaced positions along the circumferential direction. A power transmission component, which is welded in advance to the spring member and has a counterbore or screw hole drilled at a position that matches each of the relief holes, is superimposed on the surface of the spring member opposite to the armature, and the spring member is An armature assembly characterized in that the armature assembly is connected by a rivet or screw interposed between the through hole of the power transmission component and a counterbore hole or screw hole of the power transmission component. (2) The armature assembly according to claim 1, wherein each of the welded portions described above is provided at a plurality of locations adjacent to each other on the same circumferential line in the intermediate portion between the through holes. . (3) The armature assembly according to claim (1) or claim (2), wherein a thin wall portion is provided on the inner peripheral side of the spring member excluding the welded portion and the through hole portion. .
