Abstract: A clutch unit includes a lever-side clutch portion on an input side, and a brake-side clutch portion on the output side, in which the lever-side clutch portion includes a retainer for retaining a plurality of cylindrical rollers for controlling transmission/interruption of the torque input through engagement/disengagement between the lever-side outer race and an inner race transmitting the torque from the lever-side outer race to the brake-side clutch portion, and an inner centering spring including a lock portion to be locked to an end surface of the retainer, for accumulating an elastic force obtained by the torque input and for restoring the retainer to a neutral state by releasing the elastic force obtained by the torque input from the lever-side outer race and thus accumulated, and on the end surface of the retainer, a hook portion holds the lock portion of the inner centering spring in a protruding manner.

Abstract: A clutch unit includes a lever-side clutch portion for controlling transmission/interruption of rotational torque to an output side with lever operation, and a brake-side clutch portion for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reverse-input from the output side. The lever-side clutch portion includes an input-side member to which torque is input with the lever operation and claw portions extending in an axial direction are provided on an outer periphery of the lever-side outer race of the input-side member. The brake-side clutch portion includes a stationary-side member restricted in rotation, and claw portions of the lever-side outer race are brought into slidable contact with an end surface of a brake-side outer race with rotation of the lever-side outer race, the rotation being effected with lever operation.

Abstract: Provided is a clutch unit, including: a lever-side clutch portion provided on an input side, for controlling transmission/interruption of rotational torque to an output side with lever operation; and a brake-side clutch portion provided to the outside side, for transmitting a torque input from the lever-side clutch portion to the output side and for interrupting a torque reverse-input from the output side, in which: the lever-side clutch portion includes a retainer for retaining a plurality of cylindrical rollers at predetermined intervals in a circumferential direction for controlling transmission/interruption of the torque input from a lever-side outer race through engagement/disengagement between the lever-side outer race to which torque is input and an inner race transmitting the torque from the lever-side outer race to the brake-side clutch portion; and an inner centering spring including a lock portion to be locked to an end surface of the retainer, for accumulating an elastic force obtained by the torq

Abstract: To secure abrasion resistances of a brake-side outer race and a stopper contact portion, and to reduce cost, there is provided a clutch unit including: a lever-side clutch portion for controlling transmission/interruption of rotational torque to an output side with lever operation; a brake-side clutch portion for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reverse-input from the output side, in which: the lever-side clutch portion includes an input-side member to which torque is input with the lever operation; claw portions (14g) extending in an axial direction are provided on an outer periphery of the lever-side outer race (14) of the input-side member; the brake-side clutch portion includes a stationary-side member restricted in rotation, the stationary-side member being constituted by a brake-side outer race (23) arranged while being separated from the lever-side outer race (14) in the axial direction and a cover (24) attached to the brake-sid
