Abstract

A clutch is provided that includes an annular clutch housing, a driving-side rotor, a driven-side rotor having a control surface, and a rolling element located between the inner circumferential surface of the clutch housing and the control surface. The control surface faces radially outward in the clutch housing. When the driving-side rotor rotates, the rotational driving force of the driving-side rotor is transmitted to the driven-side rotor. When the driving-side rotor is driven to rotate, the rolling element rotates together with the driven-side rotor. When the driving-side rotor is not driven to rotate, the rolling element is held between the inner circumferential surface of the clutch housing and the control surface so as to prevent the driven-side rotor from rotating.
