Abstract: An endoscope includes: a rigid distal structure portion; a rotational portion; an exterior member; a bearing opposed to the exterior member and recessed from an outer surface of the distal structure portion, the bearing being; and a preventing portion. The bearing is configured to receive and support the rotational shaft and to displace the rotational shaft from the distal structure portion by the exterior member being removed from the distal structure portion. The preventing portion provided on one of the rotational portion and the distal structure portion, and configured to prevent disengagement of the rotational portion by coming in contact with the other of the rotational portion and the distal structure portion when the rotational shaft is displaced from the bearing.

Abstract: In the insertion device, the entire traction wire coupled with the swing base in the distal end constituting section is covered with a tubular elastic member in a watertight manner, and the elastic member is fixed at a position that is away from the opening of the treatment tool channel hole toward the proximal side by a predetermined distance in the longitudinal axis direction. The traction wire is not exposed to the outside, a contaminated fluid and the like do not adhere thereto during treatment, and the wrinkle of the elastic member shrunk at the time of raising the swing base is accommodated in the space created at a predetermined distance.

Abstract: The distal end portion of an insertion device is fitted into the cylindrical, hollow main body of the washing instrument. A plurality of washing ports are disposed separately from each other on the inner surface of the washing instrument main body. Washing liquids are ejected from the washing ports to a swing base at the distal end portion and its periphery in different directions for washing. When the distal end portion is detached, washing water is sprayed over a shielding wall surface, which is part of the inner surface of the washing instrument main body, to reduce the momentum of the washing liquids and thus prevent the liquids from splashing to the outside.

Abstract: An endoscope includes a distal end member including a fluid passage, a first distal end cover made of an elastically deformable material, a second distal end cover made of a material harder than that of the first distal end cover, and a nozzle. The nozzle includes a nozzle channel portion communicating with the fluid passage and an ejection port. The endoscope further includes a first nozzle configuring portion provided to the first distal end cover, configuring at least part of the nozzle, and configuring at least part of a channel bending portion having a bent shape in the nozzle channel portion. The first nozzle configuring portion is covered by the second distal end cover in a mounted state.
