PROBLEM TO BE SOLVED: To reduce the axial dimension of a clutch unit to facilitate incorporation of an automotive seat lifter portion or the like to a narrow space. SOLUTION: The clutch unit includes a lever-side clutch section 11 provided on an input side, the lever-side clutch section controlling transmission/interruption of rotary torque to an output side by lever operation; and a brake-side clutch section 12 provided on the output side, the brake-side clutch section transmitting input torque from the lever-side clutch unit 11 and also interrupting reversed input torque from the output side. The brake-side clutch unit 12 includes an output shaft 22 through which torque is outputted, and a component locking washer 31 attached to an end portion of the output shaft 22. The washer 31 has a cylindrical portion 31a extending toward the brake-side clutch unit 12 in the axial direction, the cylindrical portion 31a being press-fitted to the end portion of the output shaft 22.
