摘要： An electromagnetic clutch includes a rotation transmission member supported by an input shaft portion via a bearing. The rotation transmission member includes a movement regulating portion having abutment portions that abut against the bearing. The clutch further includes first and second spring members that bias an armature toward a braking member, and a connecting member overlaid on the movement regulating portion. The connecting member has first holes at portions facing the abutment portions, and second holes at portions facing regions between the abutment portions. One-end portions of the first and second spring members are attached to the armature. First fixing members inserted into the first holes fix the other-end portions of the first spring members to the connecting member. Second fixing members inserted into the second holes fix the other-end portions of the second spring members to the connecting member and fix the connecting member to the movement regulating portion.

摘要： Energization of an electric coil 45 produces flux for attracting an armature 40 of a clutch 25 into engagement with a rotor 37 in order to couple an input shaft 12 to an output pulley 13. When the coil 45 is de-energized, two angularly spaced permanent magnets 55,56 pull the armature 40 away from the rotor 37 and into engagement with fixed pole pieces 60,61 which cause a braking torque to be applied to the output pulley 13. The magnets 55,56 are located closely adjacent one another and only along a short arc of the armature 40 in order to enable the flux of the coil 45 to overcome the flux of the magnets 55,60 and effect easy release of the brake and engagement of the clutch when the coil 45 is energized.
