    Abstract: The disclosed technology is directed to an insertion apparatus comprises an insertion portion having a tubular body freely rotates around a longitudinal axis over an outer circumferential surface. The insertion portion is flexible and configured to be inserted into a body cavity. A drive source is configured to rotate the tubular body wherein a part of the insertion portion includes a predetermined flexural rigidity to which the tubular body being mounted thereto. The part of the insertion portion is formed of a structure that is configured in such a manner that bending of the tubular body is not caused beyond a predetermined bending angle so as to avoid stop of rotation of the tubular body by a driving force of the drive source even when an external force that intends to keep a bending shape of the body cavity is received from a wall of the body cavity in contact.

    Abstract: An introduction device applies urging force linearly generated by a spring to a nut portion screwed to a drive shaft to convert the urging force to the rotation direction of the drive shaft. This conversion returns an RL operation dial provided at the end of the drive shaft in a direction opposite to the rotation direction in which the RL operation dial is operated, and then returns the RL operation dial to an original neutral position.

    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.
