A clutch unit comprises: a lever-side clutch section (11) for controlling, by lever operation, the transmission of rotational torque to the output side and the prevention of the transmission; and a brake-side clutch section (12) for transmitting input torque, which is transmitted from the lever-side clutch section (11), to the output side and preventing reverse input torque from being transmitted from the output side. The lever-side clutch section (11) is provided with an outer centering spring (19) which is provided between a lever-side outer ring (14) rotated by lever operation and a cover (24) restrained from rotating, accumulates an elastic force generated by input torque transmitted from the lever-side outer ring (14), and returns the lever-side outer ring (14) to the neutral state by the accumulated elastic force when the input torque is released. The cover (24) has a sloped section (24g) which is in contact with the outer centering spring (19) and protrudes to the outer centering spring (19) side. A rounded corner surface (24g1) located at the outermost diameter of the sloped section (24g) is formed in a shape which minimizes the amount of movement of the outer centering spring (19) in the axial direction when the outer centering spring (19) returns to the initial state when the input torque is released. |
