The objective of the invention is to retain the wear resistances of a brake-side outer ring and a stopper-abutting portion and to reduce the cost. The invention provides a clutch unit comprising a lever-side clutch portion for controlling the transmission/interruption of a rotational torque to an output side by a lever operation, and a brake-side clutch portion for transmitting the input torque from the lever-side clutch portion to the output side and for interrupting the inverse input torque from the output side. The lever-side clutch portion includes an input-side member, to which the torque is inputted by the lever operation, and has a pawl portion (14g) extending axially on the outer circumference of a lever-side outer ring (14) constituting the input-side member. The brake-side clutch portion includes a stationary-side member constricted in rotation. The stationary-side member includes a brake-side outer ring (23) arranged at an axial spacing from the lever-side outer ring (14), and a cover (24) attached to the lever-side outer ring (14) on the lever side of the brake-side outer ring (23). The pawl portion (14g) of the lever-side outer ring (14) is brought into slidable contact with the end face of the brake-side outer ring (23) by the rotation of the lever-side outer ring (14), as caused by the lever operation, and can be brought into abutment in the rotating direction against retaining portions (24e and 24f) formed on the outer circumference of the cover (24).
