Abstract

A mounting unit (30) equipped with a tube body (31) to be mounted to the insertion part (3) of an endoscope (2) and rotatably provided around the longitudinal axis (3Aa) of the insertion part (3), anda fin part (32) provided so as to project from the outer-circumferential surface of the tube body (31) and extend in a spiral shape around the longitudinal axis of the tube body, wherein the fin part(32), which is provided on the tube body (31), is configured in a manner such that: a first amount of force (F1) required in order to topple the fin part (32) in the tip side (Yf) direction and a second amount of force (F2) required in order to topple the fin part (32) in the base side (Yr) direction, which is the direction opposite the tip side direction, are different; and the first amount of force (F1) is larger than the second amount of force (F2).

Description

technical field [0001] The present invention relates to a mounting unit that is mounted on an insertion portion of an insertion device inserted into a portion to be inspected and is rotatable about an axis of the insertion portion. Background technique [0002] Endoscopes are used in medical fields, industrial fields, and the like. [0003] A medical endoscope can observe organs and the like by inserting an insertion portion into a body as a subject to be inspected. [0004] A typical endoscope has an operation unit and an insertion unit. The insertion part of the endoscope is inserted into the alimentary canal of the digestive organ through the anus, or through the mouth, or through the nose. The insertion part is extended from the operation part, and a flexible tube part having flexibility, a bending part capable of bending in left and right directions and up and down directions, and a front end part are provided sequentially from the operation part side. [0005] An op...
