Abstract
In an endoscopic insertion instrument having a rigid tip end section, an elongated flexible body, and an angle section connected between the rigid tip end section and the flexible body, a joint construction connects an angle section to the fore end of the flexible body. A couple of connecting rings are provided opposingly at joining ends of the angle section and the flexible body. At least one aperture is provided in an outer one of the connecting rings to feed a flux. At least one angle section operating is passed through the connecting ring. The operating wire is encased in a sheathing coil, the fore end of which is fixed to the inner one connecting rings. To prevent flux from getting into the closed sheathing coil, a shield portion is formed around an outer periphery of the sheating coil over a predetremined range in axial length.
