Abstract: An insertion device sets engage range which it prescribed in return power to the neutral position by elastic force of the spring and rotation resistance force by the slide power by elastic member for dial portion performing curving operation of a curving portion. If a rotary angle is beyond an engage range, the dial part lets a rotary point of view to order return in an engage range and, if there is a rotary angle in an engage range, the dial part keeps a target part in an observation field of vision.

Abstract: An attachment unit includes a tube main body extended along a longitudinal axis in a state that a gap is provided between itself and an outer peripheral portion of an insertion section or a member on the outer peripheral portion of the insertion section, and a tube proximal end portion, provided to a proximal direction side of the tube main body, to which a proximal end of the attachment unit is placed. The tube proximal end portion includes a proximal side gap reducing portion eliminating or reducing the gap as compared with a part to an inner peripheral direction side of the tube main body between itself and the outer peripheral portion of the insertion section or the member, and is placed to a distal direction side of an insertion opening in a use situation.

Abstract: An attachment unit rotates in directions around a longitudinal axis with respect to an insertion main body when rotary drive force is transmitted from a drive force transmission unit provided to an insertion section, and allows propulsive force in one of directions parallel to the longitudinal axis to act on the insertion section by rotating in contact with a paries. The attachment unit includes a fin portion which is spirally extended along the longitudinal axis and whose dimension from the longitudinal axis to an outer peripheral end vary in accordance with how external force different from the propulsive force acts in the directions parallel to the longitudinal axis in a state that the attachment unit does not rotate with respect to the insertion main body.
