Abstract
An insertion device includes an insertion portion in which a movable member is held in contact with an outer circumferential surface of a hollow cylindrical member. When drive power is transmitted from the hollow cylindrical member to the movable member as the hollow cylindrical member is rotated about a longitudinal axis of the insertion portion, the movable member is rotated around its own axis parallel to the longitudinal axis and moved around the longitudinal axis. The insertion portion includes a membrane covering the movable member from an outer circumferential side thereof. The membrane urges the movable member toward the longitudinal axis, thereby pressing the movable member against the outer circumferential surface of the hollow cylindrical member.
