Clutch unit

A clutch unit, comprising:

• a lever-side clutch portion provided on an input side, for controlling transmission and interruption of rotational torque to an output side through a lever operation;
• and
• a brake-side clutch portion provided on the output side, for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reversely input from the output side, wherein:
• the lever-side clutch portion comprises:
• an input-side member to be rotated through the lever operation;
• a stationary-side member restricted in rotation;
• a retainer for retaining a plurality of engagement elements at predetermined intervals in a circumferential direction, the plurality of engagement elements controlling transmission and interruption of torque input from the input-side member;
• and
• an elastic member provided between the retainer and the stationary-side member, for accumulating an elastic force obtained by the torque input from the input-side member and for restoring the retainer to a neutral state with the accumulated elastic force through releasing of the torque input from the input-side member,
• the elastic member comprising a C-shaped spring member which comprises a pair of lock portions formed by bending both ends thereof to a radially inner side;
• under a state in which the elastic member is assembled, an interval between distal ends of the pair of lock portions is set smaller than an interval between proximal ends of the pair of lock portions;
• and
• when the elastic member is extended by the torque input from the input-side member, a force acting on the lock portions of the elastic member is directed to a radially inner side.

A clutch unit, comprising:

• a lever-side clutch portion provided on an input side, for controlling transmission and interruption of rotational torque to an output side through a lever operation;
• and
• a brake-side clutch portion provided on the output side, for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reversely input from the output side, wherein:
• the brake-side clutch portion comprises:
• an output-side member from which torque is output;
• a stationary-side member restricted in rotation;
• and
• a friction ring provided to the stationary-side member, for imparting rotational resistance to the output-side member by a frictional force which is generated between the output-side member and the friction ring by press-fitting the friction ring to the output-side member;
• and
• the friction ring has an inner diameter formed in a circular shape and is made of a material capable of keeping a fixed relationship between the output-side member and the friction ring.
