Abstract: An insertion device includes a shape-variable tube elastically returning while the shape-variable tube bends at a tube bending radius of a tube radius boundary value or more, and a shaft rotating around a shaft axis inside the shape-variable tube so that the shaft transmits a driving force to drive a motion section from a first extending direction toward a second extending direction. The shaft elastically returns while the shaft bends at a shaft bending radius of a shaft radius boundary value or more, and rotates without being deformed while the elastic return is impossible when the shape-variable tube bends in an elastically returnable range.

Abstract: An insertion apparatus includes: a flexible tube; an electric driving source arranged on a proximal end side of the flexible tube; a driven portion arranged on a distal end of the flexible tube; and a single driving force transmitting member inserted in the flexible tube and formed by being wound in a coil shape. For the driving force transmitting member, first torsional rigidity in a first rotating state of being rotated in a direction of being wound in the coil shape is set higher than second torsional rigidity in a second rotating state of being rotated in an opposite direction; and the driven portion performs a first motion by the first rotating state and performs a second motion requiring a larger amount of force than the first motion by the second rotating state.

Abstract: An attachment unit includes a tube main body attached to an insertion section of an endoscope and disposed to be rotatable around a longitudinal axis of the insertion section and a fin section protrudingly provided on an outer circumferential surface of the tube main body and spirally extended along a longitudinal axis of the tube main body. In the fin section, a first force amount necessary for bringing down the fin section toward a distal end side direction and a second force amount necessary for bringing down the fin section toward a proximal end side direction, which is an opposite direction of the distal end side, are different. In the fin section provided on the tube main body, the first force amount is larger than the second force amount.
