Claims

[Claims for Utility Model Registration] Inner and outer hubs that are mutually divided and connected by splines, and an armature that is supported by one of these hubs via a leaf spring; A connecting member that connects the two hubs and is slidable relative to one of the hubs in the axial direction and maintains a predetermined frictional force against the relative sliding, and supports the armature of the two hubs. The electromagnetic hub is moved in the same direction as the armature against the frictional force using the suction movement of the armature to adjust the gap between the armature and the transmission friction surface facing it. It is provided in a clutch or an electromagnetic brake, and enables the above-mentioned connecting member to move relative to one of the inner and outer hubs in a direction other than the axial direction, and between the two hubs or between them. In the automatic air gap adjusting device for an electromagnetic clutch/brake, an elastic member is interposed between the members of the torque transmission system, and the elastic member absorbs torque vibration caused by the buckling of the spline portion. A connecting member that is movable relative to the hub in a direction other than the axial direction, and a contact portion between the connecting member and one of the hubs is formed to be harder than the respective contact surfaces of the hub and the connecting member. An automatic air gap adjustment device for an electromagnetic clutch/brake, characterized in that a shim is inserted.
