Abstract

An endoscope includes a bending section, an operation section including first and second operation sections, a grasping section housing, an exterior housing, a main frame, first and second towing members, first and second towing-member-adjusting sections, a first fixing member for fixing the first-towing-member-adjusting section, and a second fixing member for fixing the second-towing-member-adjusting section. The first and second fixing members are formed by flat plates having a same shape, selected to be fixed to the main frame with one end side directed to the insertion section on the first operation section side or fixed with the other end side directed to the insertion section on the second operation section side, and formed asymmetrically with respect to the center axis orthogonal to a direction in which the first and second towing members extend such that fixed sections are closer to the one end side than the other end side.
