PROBLEM TO BE SOLVED: To provide a clutch capable of reducing collision noise when connecting a pulley 30 with an armature 40 or when separating the pulley 30 from the armature 40 in the clutch of self-holding type.SOLUTION: Stoppers 56,57a which regulate the movement range of a moving body 52 are formed with non-magnetic material, and delivering members 57b, 58a which allow magnetic flux to be delivered between the delivering members 57b, 58a and the moving body 52 are arranged on the inner circumferential side or the outer circumferential side of the moving body 52. As the moving body 52 comes close to the first stopper 56 or the second stopper 57a, a force actuating the moving body 52 by virtue of magnetic force is changed from the rotation axial direction to the rotation axis vertical direction and the force in the rotation axial direction decreases. |
