Title: FLEXIBLE TUBE AND INSERTION APPARATUS
Abstract:
This flexible tube, which constitutes a portion of an insertion part defining a central axis of an insertion apparatus inserted into a hole, includes: a spiral tube which has concavo-convex parts formed such that convex sections and concave sections are alternately formed on a pair of edges of a strip-shaped member extending in the longitudinal axis of the spiral tube, and has a densely wound region in which the convex sections of the concavo-convex parts facing each other along the central axis press one another in a state in which the strip-shaped member is wound in a spiral shape; and a cylinder-shaped outer cover covering the outer surface of the spiral tube.
