Patent ID: 8678155

Claim:
A clutch unit, comprising: a lever-side clutch portion disposed on an input side of the clutch unit, and being configured to control transmission/interruption of rotational torque to an output side of the clutch unit with lever operation; and a brake-side clutch portion disposed on the output side of the clutch unit, and being configured to transmit torque input from the lever-side clutch portion to the output side and to interrupt torque reverse-input from the output side, wherein the lever-side clutch portion comprises an input-side member to which torque is capable of being input with the lever operation, a coupling member configured to transmit the torque input from the input-side member to the brake-side clutch portion, a plurality of engagement elements configured to control transmission/interruption of the torque input from the input-side member through engagement/disengagement between the input-side member and the coupling member, a retainer that is a cylindrical member having a plurality of pockets that are spaced equally apart in a circumferential direction, the plurality of pockets accommodating the plurality of engagement elements, and an elastic member including lock portions to be locked to the retainer, and being configured to accumulate an elastic force obtained by the torque input from the input-side member and to restore the retainer to a neutral state by releasing the elastic force obtained by the torque input from the input-side member and thus accumulated, an end portion of the retainer has two cutout recessed portions formed therein, each of the two cutout recessed portions having an end surface, the end surfaces of the two cutout recessed portions being adjacent to each other, and hook portions protrude in a circumferential direction from the adjacent end surfaces of the two cutout recessed portions, the hook portions holding the lock portions of the elastic member in contact with the adjacent end surfaces to lock the lock portions of the elastic member.
