案登録請求の範囲第１項に記載の内視鏡。[Scope of Claim for Utility Model Registration] (1) In an endoscope in which a channel and other internal components of the endoscope are inserted into an insertion section having a curved tube section on the distal end side, the channel is inserted into at least the curved tube section. The tube is composed of an irregularly shaped tube whose outer peripheral side cross section is formed into a non-circular shape, and the inner surface of the curved tube portion is in contact with the outer surface of the non-circular shaped portion of the channel to restrict the radial movement of the channel. What is claimed is: 1. An endoscope characterized by having a protrusion protruding from the endoscope. (2) The endoscope according to claim 1, wherein the protrusion is a wire guide for guiding an operating wire for bending the curved tube section. (3) The endoscope according to claim 1, wherein the protruding portion is formed by partially bending a peripheral wall constituting the curved tube portion inward.
