摘要： Provided is a clutch unit, comprising: a lever-side clutch portion (11) for controlling transmission and interruption of rotational torque to an output side through lever operation; and a brake-side clutch portion (12) for transmitting torque input from the lever-side clutch portion (11) to the output side and for interrupting torque reversely input from the output side, wherein: the lever-side clutch portion (11) comprises an outer centering spring (19) provided between a lever-side outer ring (14) to be rotated through the lever operation and a cover (24) restricted in rotation, for accumulating an elastic force obtained by torque input from the lever-side outer ring (14) and for restoring the lever-side outer ring (14) to a neutral state with the accumulated elastic force through releasing of the torque input from the lever-side outer ring (14); the cover (24) comprises an inclined portion (24g) which abuts on the outer centering spring (19) and swells to the outer centering spring (19) side; and a rounded corner surface (24g 1 ) situated at an outermost diameter of the inclined portion (24g) is formed into a shape for controlling an amount of axial movement of the outer centering spring (19) when the outer centering spring (19) is restored to an initial state through the releasing of the torque input from the lever-side outer ring (14).

摘要： Provided is a clutch unit, including: a lever-side clutch section (11) provided on an input side, for controlling transmission and interruption of a rotational torque to be input through lever operation; and a brake-side clutch section (12) provided on an output side, for transmitting the rotational torque from the lever-side clutch section (11) to the output side, and interrupting a rotational torque to be reversely input from the output side. The brake-side clutch section (12) has a two-layer structure, in which two one-way clutches (50) and (51) are arranged side by side in an axial direction. The one-way clutch (50) on one side is configured to interrupt a rotational torque in a forward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions (23a) and (27a), whereas the one-way clutch (51) on another side is configured to interrupt a rotational torque in a backward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions (33a) and (37a) arranged in an opposite direction to that of the projection and depression portions (23a) and (27a). Accordingly, the brake-side clutch section (12) serves as a two-way clutch.
