1. An electromagnetic clutch comprising:
an input shaft portion that rotates upon receiving transmitted power; a rotor that radially extends outward from the input shaft portion and rotates integrally with the input shaft portion; a field core that includes an exciting coil and is provided at a position where a magnetic flux of the exciting coil passes through the rotor on one side of the rotor in an axial direction in a state in which rotation is regulated; a braking member arranged on the other side of the rotor in the axial direction in the state in which rotation is regulated; a bearing provided on the other side of the rotor in the axial direction on the input shaft portion; a rotation transmission member that includes a movement regulating portion that abuts against the bearing from a side of the rotor and regulates movement of the rotation transmission member to the one side in the axial direction and is rotatably supported by the input shaft portion via the bearing, the movement regulating portion including a plurality of abutment portions that are formed at intervals in a rotation direction of the rotation transmission member and abut against the bearing; a connecting member that is overlaid on one surface of the movement regulating portion in the axial direction, the connecting member including a plurality of first holes respectively provided at portions facing the plurality of abutment portions and a plurality of second holes provided at portions facing regions between the plurality of abutment portions; an armature that is formed into an annular shape with a through hole at a center and arranged between the rotor and the braking member in a state in which the input shaft portion is inserted in the through hole, and is movable in the axial direction by a distance corresponding to an air gap; a plurality of first spring members and a plurality of second spring members which include one-end portions attached to the armature and other-end portions and support the armature while biasing the armature toward the braking member; a plurality of first fixing members that are inserted into the plurality of first holes of the connecting member, respectively, and fix the other-end portions of the plurality of first spring members to the connecting member; and a plurality of second fixing members that are inserted into the plurality of second holes of the connecting member, respectively, and fix the other-end portions of the plurality of second spring members and the connecting member to the regions of the movement regulating portion. |
