PROBLEM TO BE SOLVED: To provide a clutch unit which can easily achieve the reduction of the number of part items, and the improvement of assembling workability.SOLUTION: A clutch unit is composed of a lever-side clutch part 11 which controls the transmission and block of rotational torque inputted by a lever operation, and a brake-side clutch part 12 which transmits the rotational torque from the lever-side clutch part 11 to an output side, and blocks the rotational torque which is reversely inputted from the output side. The lever-side clutch part 11 comprises: an outer ring 14 to which the rotational torque is inputted by the lever operation; an inner ring 15 which transmits the rotational torque inputted from the outer ring 14 to the brake-side clutch part 12; a plurality of cylindrical rollers 16 which control the transmission and block of the rotational torque from the outer ring 14 by engagement and release between the outer ring 14 and the inner ring 15; and a cage 17 which is sandwiched between the outer ring 14 and a cover 24 in an axial direction, and holds the cylindrical rollers 16. In the cage 17, a spring piece 17e which energizes an elastic force to the axial direction between the outer ring 14 and the cover 24 is integrally formed at an axial end face 17c. |
