<P>PROBLEM TO BE SOLVED: To provide a clutch capable of being miniaturized in a radial direction and a motor including the clutch. <P>SOLUTION: This clutch 3 includes: an annular clutch housing 31; a driving-side rotor 32 to be driven to rotate; and a driven-side rotor 35 having a control surface 73 facing radially outward in the clutch housing 31 and transmitted with rotational driving force of the driving-side rotor 32 when the driving-side rotor 32 rotates. A rolling element 34 is arranged between an inner peripheral surface of the clutch housing 31 and the control surface 73. When the driving-side rotor 32 is driven to rotate, the rolling element 34 rotates together with the driven-side rotor 35. When the driving-side rotor 32 is not driven to rotate, the rolling element 34 is held between the inner peripheral surface of the clutch housing 31 and the control surface 73 to prevent the driven-side rotor 35 from rotating. The driven-side rotor 35 includes a driven-side coupling portion 72 that can be coupled to and integrally rotatable with the driving-side rotor 32. The control surface 73 and the driven-side coupling portion 72 are provided at different positions in the axial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
