To prevent coupling breakage between an elastic body and an outer ring due to friction heat of an armature and a rotor, an solenoid clutch coupling is provided with an elastic body ( 3 ) elastically coupling a hub ( 10 ) attached to a rotation shaft ( 6 ), and an outer ring ( 20 ) coupled to an armature ( 5 ) solenoidally moved close to and apart from a rotor ( 4 ), a sleeve ( 40 ) buried in an outer peripheral portion of the elastic body ( 30 ), a fit layer ( 32 ) constituted by a part of the elastic body ( 30 ) in an outer peripheral side of the sleeve ( 40 ) and attached to an inner peripheral surface of the outer ring ( 20 ), and non-cylindrical surfaces ( 21 a) engaging with the fit layer ( 32 ) in a circumferential direction, and axial stoppers ( 23, 24 ) to an outer periphery of the elastic body ( 30 ) in a sleeve ( 21 ) of the outer ring ( 20 ).
