Patent ID: 7722532

Claim:
An electric bending endoscope comprising: a bending portion arranged to an inserting portion; a first unit which has a frame unit which holds a motor that generates driving force for bending the bending portion, the frame unit being connected to a cord for supplying a signal for driving the motor from a bending control device; a second unit which is separable from the first unit and which has a transmitting member for transmitting the driving force of the motor to the bending portion, the second unit having a main frame to which is connected the inserting portion; and a buffering member that is a plate member, the buffering member being connected to the frame unit at a first portion of the plate member and to the main frame at a second portion of the plate member, an intermediate portion between the first portion and the second portion of the plate member being arranged to traverse across a junction between the first unit and the second unit, the buffering member absorbing a force applied to the inserting portion by an external operation between the first portion connected to the frame unit and the second portion connected to the main frame, wherein the first unit has a frame unit which comprises an inner frame for holding the motor and an outer frame for holding the inner frame, and the buffering member further includes a fixing member which fixes the inner frame of the first unit and a main frame arranged to the second unit and the frame unit and the main frame are fixed via the fixing member by using a positioning tool for positioning in a three-axial direction.
