摘要：
An electrically-bent endoscope includes a bend driving portion for bending a bending portion. The bend driving portion has a motor for generating driving force, a gear train for transmitting driving force generated in the motor, a sprocket for converting driving force of the motor to a back and forth movement of bending operation wires for bending the bending portion at the head portion of an inserting portion, and a clutch mechanism for connecting and disconnecting driving force transmitted from the gear train to the sprocket. The clutch mechanism includes a transmitting member for connecting and disconnecting the gear train and sprocket, a thrust mechanism for moving the transmitting member in the axial direction of the sprocket and a clutch operating member, connected to the thrust mechanism, for inputting instructions for connecting and disconnecting the gear train and the sprocket.
