ABSTRACT:
A steering section for an endoscope or borescope employs a plurality of steering cables that pass through peripheral bores of axially aligned flat washers. Spacer beads are strung on the cables between the washers to define hinge points for the bending of the steering section. The spacer beads are tapered beads having a relatively wide base and relatively small, flat nose surface. A through-passage in the bead has a relatively narrow nose portion with a small clearance with respect to the steering cable, and a tapered or countersunk portion that expands basewards and prevents the spacer bead from binding the cable.
