Abstract
In an insertion equipment, a cover film forming part of an outer periphery surface of an insertion section has flexibility and is formed of a resilient material. In the insertion section, a protrusion protruding to an outer periphery side is covered by the cover film from the outer periphery side, and the protrusion moves around a longitudinal axis with respect to the cover film due to a transmission of a drive force for rotating an attachment tool. A ring member of the attachment tool is attached to the outer periphery side of the cover film in a state that the protrusion is pressed to an inner periphery side by the ring member via the cover film, and is rotatable around the longitudinal axis with respect to the cover film.
