Abstract
A slide member advancing/retracting mechanism includes an outer sheath; a slide member installed in the outer sheath to be slidable in an axial direction without rotating relative to the outer sheath; and an operating portion which can be freely rotated relative to, and about a common axis of, the outer sheath and the slide member. The operating portion can be operated so as to linearly advance/retract the slide member within the outer sheath.
