Abstract
An electric bending endoscope comprises a bending portion arranged to an inserting portion, a bending driving unit and a buffering member. The bending driving unit bends the bending portion, and includes a motor, a first unit and a second unit. The motor generates driving force for bending the bending portion. The first unit holds the motor. The second unit includes a driving force transmitting member. The buffering member connects the first unit to an outer member of the inserting portion, a connecting code and a switch. The buffering member absorbs external force generated during the operation of the electric bending endoscope.
