Title:
INSERTION DEVICE
Document Type and Number:
Japanese Patent JP2017000330
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an insertion device capable of reducing the diameter of a built-in object by inhibiting protrusion of a tube to the outside, with the tube fixed to any position relative to the outer periphery of a cylindrical member, improving assemblability when the tube is fixed to any position relative to the outer periphery of the cylindrical member and, after the tube is disposed relative to the outer periphery of the cylindrical member, capable of retaining the position of the tube relative to the outer periphery of the cylindrical member.SOLUTION: The insertion device includes: an insertion part to be inserted toward an object; a cylindrical member disposed in the insertion part; a tube for covering the outer periphery of an end of the cylindrical member in the insertion part and having flexibility; a groove formed around the outer periphery of a part, out of the tube, for covering the cylindrical member; and a fastening part disposed at the groove for fastening the tube to the cylindrical member by the elastic force.SELECTED DRAWING: Figure 3
