Abstract

An insertion instrument comprises an insertion portion including a bending portion provided at a distal end side of the insertion portion, a first wire provided in the insertion portion, and an operation portion provided at a proximal end side of the insertion portion. The operation portion includes a bending operation unit. The bending operation unit includes a lever having a central shaft defining a central axis, a rotor coupled to the lever, a wire attachment surface to which the first wire is attached. An inner surface of the operation portion includes a receiver body and a restriction body. The receiver body supports the rotor for rotation about the central axis and for movement of the lever from a neutral position to an inclined position, where, in the inclined position, the central shaft is inclined relative to the central shaft in the neutral position. Movement of the lever from the neutral position to the inclined position pulls the first wire to bend the bending portion. The restriction surface restricts a portion of the rotation of the rotor about the central axis.
