Abstract
A clutch unit includes a lever-side clutch section provided on an input side, for controlling rotational torque to be input through lever operation, and a brake-side clutch section provided on an output side, for transmitting the rotational torque from the lever-side clutch section to the output side, and interrupting rotational torque to be reversely input from the output side. The brake-side clutch section has a two-layer structure, in which two one-way clutches are arranged side by side in an axial direction. The first one-way clutch interrupts rotational torque in a forward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions, whereas the second one-way clutch interrupts rotational torque in a backward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions arranged in an opposite direction.
