An electric bending endoscope includes a bending portion arranged to an inserting
portion and a bending driving unit which bends the bending portion. In the electric
bending endoscope, the bending driving unit includes a motor which generates driving
force for bending the bending portion, a first unit which holds the motor, a driving
force transmitting member which transmits the driving force of the motor, and a
second unit which bends the bending portion by the driving force of the motor.
The electric bending endoscope further includes a first holding member which detachably
supports, to the first unit, a rotating shaft arranged to the driving force transmitting
member of the second unit.
