  "textContent": "A yoke core (60) of an electromagnetic brake system (100) includes a rotation shaft hole portion (60b) through which a rotation shaft (66) is penetrated, and additionally includes an inner yoke portion (60c) and an outer yoke portion (60d) which are arranged on both inner and outer sides, by pinching a concave groove (60a). A coil (64) is accommodated in the concave groove (60a) and a magnetic flux is generated by applying electricity to attract an armature (52). The armature (52) has a penetrating hole portion (52a) in the center, and a protruded shaft portion 61 formed on the inner yoke portion (60c) is inserted to the penetrating hole portion (52a). The rotation shaft (66) has one side thereof rotatably supported by a support portion (70a) of a housing (68), and the other side thereof rotatably supported by the protruded shaft portion (61) via the armature (52) and a planetary gear mechanism. Accordingly, it is not necessary to provide bearings or the like.",
