Abstract

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.
