In the present invention, a connecting part for a bending part used in an insertion part of an endoscope connects each bending piece through use of a sliding surface parallel to a turning axis of bending and a sliding surface in the direction orthogonal to the turning axis. External forces acting in the turning axis direction are received by the sliding surfaces in the direction orthogonal to the sliding surface, and the sliding surfaces are therefore resistant to disconnection or twisting. |
