A reverse-input shutoff clutch according to the invention includes an outer ring as an input-side rotation member, an inner ring as an output-side rotation member, rollers as torque transmission means, a cage for retaining the roller, a centering spring as an elastic member for positioning the cage, a housing as a stationary-side member, and a sliding spring coupled to and co-rotate with the cage while sliding against the housing. With the constitution described above, the clutch applies rotational resistance induced by friction resistance to the cage.
